Angesichts einer drastischen Übernutzung der maritimen Fischbestände wird vielfach ein Übergang zu einer nachhaltigen Fischerei eingefordert. Favorisiert werden häufig Strategien einer Privatisierung und Vermarktlichung der Fangrechte, um einen verantwortungsvollen, nachhaltigen Umgang mit den maritimen Ressourcen zu erreichen. Wie allerdings am Beispiel der Neuordnung der Fischerei in Chile durch das Gesetz "Ley Longueira" im vorliegenden Artikel deutlich gemacht wird, führen diese Strategien zur Verdrängung traditioneller Kleinfischer und sie fördern letztlich eine ökologisch problematische industrielle Fischerei. Unter Bezug auf das sozial-ökologische Leitbild der nachhaltigen Arbeit kann konstatiert werden, dass marktbasierte Strategien zur Erreichung von Nachhaltigkeit in der Fischerei zumeist ihr Ziel verfehlen. Sie verschärfen die sozialen und ökologischen Krisen und legitimieren teilweise Praktiken des Ocean Grabbings. Um eine nachhaltige Arbeit in der Fischerei zu gewährleisten, sind daher gemeinschaftsbasierte Ansätze der Ressourcennutzung zu bevorzugen. In view of the drastic overexploitation of maritime fish stocks, a transition towards a sustainable fishery is required. Strategies of privatization and marketisation of fishing rights are commonly favored in order to achieve a responsible and sustainable management of maritime resources. However, as set out in this article by the example of the reorganization of the fishery by the law "Ley Longueira" in Chile, these strategies often displace traditional small-scale fisheries and ultimately promote an industrial fishery, which is ecologically problematic. As can be argued with reference to the socio-ecological model of "sustainable work", market-based strategies to achieve sustainability in fisheries often fail. They exacerbate the social and ecological crises and legitimize ocean grabbing. To ensure sustainable work in fisheries, community-based approaches to resource use are therefore preferable.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Other literature type 2023Publisher:Unknown Authors: Dehler, Marcel; Dehler, Marcel;Plant protection products are a significant component of conventional arable farming in Germany. They have helped increase land productivity and reduce yield losses, thereby providing a significant contribution to food security. However, plant protection products have negative impacts on biodi-versity. Moreover, their degradation products can be found in ground and surface waters, and they are associated with negative effects on human health. Against this background, the aim of policy is to reduce the use of plant protection products and the associated risks. By contrast, the questions of whether and how farms can adapt their production systems and the resulting costs remain largely unanswered. Similarly, although the advantages and disadvantages of different policy implementation strategies for reducing plant protection products are discussed at both the European and national levels, the scientific publications are aimed primarily at intro-ducing a tax model. A concrete comparison of different policy measures and an assessment of the adaptation reactions as well as the associated consequences, taking agricultural expertise into ac-count, usually is not carried out. Against this background, based on a typical farm in the soil-climate region “Südhannover” and us-ing a focus group approach with farmers and advisors, the present dissertation investigated which farm adaptation measures can reduce the risks to humans and the environment associated with the use of plant protection products by 25 % or 50 % and what adaptation costs result from such measures. The risks posed by pesticides were determined with the help of the Pesticide Load Indi-cator (PLI). In order to be able to quantify the yield effects as a result of reduced pesticide use, regional and national trial evaluations were consulted. In addition, the expected yield effects were differentiated between a best and worst case and a “normal year”. In order to reduce the PLI by 25 %, farmers first will substitute less toxic active substances for those with a higher PLI. Similarly, weeds are increasingly regulated mechanically and non-selective herb-icides are replaced by mechanical tillage before summer crops. If no crop-specific PLI reduction is required and alternative crops are available, farmers will substitute crops with a low net margin per PLI unit used (e.g. rape with grain maize). If the PLI is halved, reduced fungicide and insecticide use across crops or later sowing dates in cereals also are suitable for reducing the risks from plant protection products. With a crop-specific PLI reduction of 25 %, changes in the net margin range from + 25 €/ha for sugar beet to – 60 €/ha for stubble wheat can be expected. If the PLI has to be reduced by 50 % for each individual crop, the range of adjustment costs among the crops increases further. While the PLI can be halved for oilseed rape with costs of about 50 €/ha, the net margin for stubble wheat or winter wheat after silage maize decreases by about 150 €/ha. At farm level, the results show that the more adaptation flexibility farmers are granted, the lower the adaptation costs. With a 25 % reduction of the PLI and taking into account the active ingredient substitution, manageable adaptation costs of between about 10 €/ha and 20 €/ha can be expected, depending on the adaptation flexibility granted. The change in grain units (GU) produced varies between + 4 % and – 5 %. On the other hand, the adjustment costs increase disproportionately strongly with a PLI reduction of 50 %, so that an operational net margin reduction of between about 80 €/ha and a maximum of 125 €/ha can be expected. With a PLI reduction of 50 %, the change in GU produced is between 0 and a maximum of -7 %. As farmers are in competition with their colleagues on the land and tenancy markets, they usually cannot afford to voluntarily switch to production systems that cause lower yields or cost increases and thus put them at a competitive disadvantage vis-à-vis neighbouring farms. Policymakers there-fore must change the framework conditions for all farms in such a way that the adaptation of pro-duction systems is either mandatory or economically viable. A wide range of policy measures are available for this purpose. Following on from the results of the adaptation costs, it therefore was examined how policymakers can use the "PLI" starting point to achieve their reduction target. In order to expose the selected policy measures and impact assessments to the critical judgement of the focus group, four concrete policy measures were developed that can achieve PLI reduction while addressing different secondary objectives. The measures examined include an individual farm PLI ceiling, a licensing system with tradable use rights, a state subsidy for low PLI hectare values and an increase in crop protection product prices depending on PLI. It was assumed that the policy measures would be introduced throughout the European Union. The effects that can be ex-pected on production, farm incomes and the administrative and control costs for farmers and the state were worked out in an impact assessment. The following results emerged: In the case of a PLI ceiling for individual farms and at the same time for individual crops, every farm must, in principle, reduce its PLI use if it does not yet meet the targets in the initial situation. This leads to an area-wide risk reduction without shifting the production of individual crops to third countries. However, the adjustment flexibility for farmers is comparatively low compared with other policy options. The control is carried out with the help of an online database. In contrast, an increase in plant protection prices depending on the PLI has the advantage of not having to control all farms, but only "bottlenecks" such as traders and manufacturers of plant pro-tection products. A disadvantage is the high negative income effect for the farms (> 220 €/ha) if the PLI is halved. In addition, readjustments of the levy level are to be expected in order to ap-proach the reduction target. If the PLI use rights are distributed in a licensing system depending on acreage, it can be expected that crops with a high net margin per PLI unit used will be cultivated preferentially. On the other hand, crops with a low net margin per PLI unit used will increasingly be pushed out of cultivation. Farm managers can decide on the basis of the market price for the tradable PLI use rights whether to use them themselves on the farm or sell them on the market. As a result, it is to be expected that PLI units will be saved, especially on marginal arable sites where this saving causes only low costs. The PLI units freed up there move primarily to regions where an above-average net margin per PLI unit can be produced. These are classically favourable locations for arable farming. The comparatively high administrative costs required for tradability must be viewed critically. For the state, this additional effort goes hand in hand with the advantage that the reduction target can be targeted precisely. If the state decides to promote low PLI hectare values with a premium, a negative income effect at farm level can be prevented, as the farm only participates if its costs are lower than the premium payment. The acceptance of the policy measure by farmers is high. A major challenge, however, is the controllability, as there are high incentives to undermine the system. DOI:10.3220/REP1678173967000

Das Wissen um die endliche Verfügbarkeit konventioneller, fossiler Rohstoffe führte zur intensivierten Auseinandersetzung mit alternativen, erneuerbaren Energiequellen. Im Zuge dieses als Energiewende bezeichneten Prozesses hat die thermische Nutzung des Untergrundes als Speicher, aber auch als Quelle von Wärme deutlich zugenommen. Diese Entwicklung verstärkte die Forschungsbestrebungen für die Beschreibung thermischer Parameter des Untergrundes sowie der Bauwerke, die zur Wärmegewinnung genutzt werden, über Temperaturverteilungen während Installation und Betrieb. Die zugehörigen Temperaturmessungen können dafür zeitgemäß, kostengünstig und unaufwendig mit Ramanspektrum basierter, verteilter Temperaturmessung auf Glasfaserkabeln (DTS) durchgeführt werden. In der vorliegenden Arbeit wurde vom aktuellen, erkundungsbezogenen Stand der Technik aus, dem Thermal-Response-Test, untersucht, inwieweit eine Vergleichbarkeit zwischen unterschiedlichen Erdwärmesonden eines Sondenfeldes gegeben ist und diese Ergebnisse auch nicht etablierten, tiefenaufgelösten TRT gegenübergestellt. Aufgrund der Notwendigkeit der Verfügbarkeit von Erdwärmesonden zur TRT-Durchführung wurde sich entsprechend auch mit alternativen Erkundungsmöglichkeiten auseinandergesetzt. Dafür wurde sich mit der Temperaturcharakterisierung von flachem Untergrund sowie der Erdwärmesonde (EWS) beschäftigt. Temperaturmessungen während Aufheizen und Abkühlen des Untergrunds wurden mit DTS durchgeführt und alternativen Erkundungsverfahren, wie Direct-Push, gegenübergestellt. In Kombination mit den TRT-Temperaturverteilungen zeigte sich dabei, dass nicht nur geologische Schichten unterschieden werden können, sondern auch, dass der Ausbau der Erdwärmesonde einen erkennbaren Einfluss auf die Messungen hat. Aus diesem Grund wurden die Arbeiten mit Untersuchungen zur Nutzung der Hydrationswärme als Werkzeug des Qualitätsmanagements von EWS abgeschlossen. Dabei wurde auf numerische Wärmeleitungsmodellierung, Laborversuche und Feldversuche zurückgegriffen. Aus der Summe der Ergebnisse wurden unterschiedliche Erklärungsansätze abgeleitet, welche notwendig sind für die Abschätzung, inwieweit die gefundenen Beobachtungen zur Erkundung und zum Qualitätsmanagement von Erdwärmesonden beitragen können. Dabei zeigte sich, dass verteilte Temperaturmessungen im Allgemeinen gut dazu geeignet sind, das relative Wärmespeichervermögen des Untergrundes zu ermitteln sowie mögliche Fehlstellen in der Hinterfüllung einer EWS zu detektieren. Damit kann die Temperaturmessung innerhalb einer EWS dazu genutzt werden, künftige Nutzungsarten zu definieren und die EWS vom Einbau an auf ihre Qualität zu überprüfen. Die Ankopplung dieser Versuche an herkömmliche Verfahren wie den Thermal-Response-Test hat sich bewährt, aber auch gezeigt, dass die Ergebnisse, die in TRT ermittelt werden, stark von den Einbaubedingungen der EWS abhängen. Eine direkter Vergleich von unterschiedlichen TRT eines EWS-Feldes (quartäre Sedimente, Sand, Kies, Schluff) wirft dabei Fragen zur Übertragbarkeit von TRT-Ergebnissen auf Nachbarsonden auf, die nicht abschließend geklärt werden konnten. Alle Temperaturdaten aus den Experimenten können von den Archivservern des Helmholtz-Zentrums für Umweltforschung (UFZ) bezogen werden. Die Ordner-Struktur des Archivs ist in Appendix A dargestellt. Zusätzlich sind die Daten der angesprochenen Publikationen hinterlegt. Link: https://www.ufz.de/record/dmp/archive/6446/de/.

The knowledge about the limited availability of conventional, fossil energy resources directed the focus on alternative, renewable energy resources. In the course of this energy transition, there is an increased use of the shallow subsurface for thermal energy mining and storage. This increase in use led to deeper research in the field of characterisation of thermal properties of the (shallow) subsurface as well as investigations in related thermal energy mining systems like borehole ground heat exchanger (BHE). Hereby, temperature evolution during operation or exploration of the BHE with thermal response tests (TRT) were of special interest. Respective measurements can be done by Raman-spectre based distributed temperature sensing (DTS). In the presented work the actual standard tool for geothermal exploration, the TRT, is the basis for further investigation. Here, the comparability between TRTs of different BHE at the same test site is of special interest as well as the comparison to the not widely established enhanced (depth depending) TRT. As the TRT itself is in need of a BHE, approaches more easy to apply were also investigated. To achieve the mentioned points, temperature evolution was measured with the help of DTS within the subsurface as well as within BHE. This was done during heating and cooling phases and partially compared to alternative exploration data like various Direct-Push (DP) techniques. The analysis of the temperature distributions showed not only that different geological layers can be distinguished during exploration phase but also that the construction process and quality have a measurable impact on the results. This led to investigations of the usability of hydration heat for BHE quality management by field site temperature measurements as well as laboratory and numeric analysis. From the sum of the results multiple explanations were deduced which help to understand how the results of the exploration and the quality management approaches can help in determining the type of use of future BHE projects. Furthermore, it was shown that distributed temperature measurements are generally well suited for deduction of subsurface relative thermal storage potential as well as detection of possible failures within the grouting of a BHE. Temperature measurements in BHE can therefore be used to define the future thermal usage of the subsurface as well as help detecting failures of the BHE from installation onwards. Combining those approaches with conventional TRT was successful. However, it could be shown that the results of TRT strongly depend on BHE installation procedure. It is also shown that the direct comparison of different BHE from the same field site (quarternary sediments, sand gravel, tilt) shows varying results, leading to questions about the comparability of TRT of adjacent BHE which could not finally be resolved. The data of all experiments is stored at the science-server of the Helmholtz-Centre for Environmental Research (UFZ). The folder structure of the server can be found in appendix A.

Die vorliegende Arbeit befasst sich hauptsächlich mit dem Thema Energie, dazu wurde eine Literaturrecherche durchgeführt. Es wurde ein Konzept erarbeitet, welches aus einem Zusammenschluss erneuerbarer Energien und verschiedenen Technologien besteht, aber auch der Natur ihren Platz zugesteht. Dieses Konzept wird mittels technischer Zeichnungen dargestellt, anschliessend wurden, durch Berechnungen und Simulationen, die dazugehörigen Werte der verschiedenen Systeme und Anlagen ermittelt. Das Konzept besteht aus zwei Gebäudekomplexen die Platz für zirka 12'000 Personen bieten, sie sind mit einer Fassaden- und Dachbegrünung ausgestattet und von einem Pumpspeicherkraftwerk, welches durch einen Wald kaschiert wird, umgeben. Es wurde darauf geachtet, dass verschiedene Anlageteile des Gesamtprojekts multifunktionell sind, das heisst Energie produzieren, Platz für die Natur lassen und den Bewohnern als Naherholungsgebiet dienen. Die Gebäudekomplexe besitzen verschiedene Photovoltaikanlagen, welche in den oberen Südfassaden integriert wurden, sich auf den Süddächern oder auf dem Pumpspeicherkraftwerk befinden. Die tagsüber durch die Photovoltaik erzeugte Energie, wird in den Gebäuden etagenweise mittels Akkus/Batterien gespeichert und für die Nacht verfügbar gemacht. Energieüberschüsse, welche mehrheitlich durch die Photovoltaikanlage des Pumpspeicherkraftwerkes erzeugt wurden, werden in diesem als potentielle Energie gespeichert. Das heisst am Tag wird Wasser mittels «Solarstrom» hochgepumpt und in der Nacht mittels Turbinen wieder in elektrische Energie umgewandelt. Die zwei Gebäudekomplexe A+B, sind jeweils in drei Häuser für rund 2'000 Personen gegliedert und besitzen ein eigenes, von den anderen Häusern unabhängiges, Heizungs-/Kühlungs-, Lüftungs- und Warmwasserbereitungssystem. Dieses System besteht aus Wärmepumpen und sorgt dafür, dass die Heizung/Kühlung, Kontrollierte Wohnungslüftung, sowie die Warmwasserbereitung pro Haus möglichst «klimaneutral» betrieben werden. Dazu wird das aufbereitete Hausabwasser, welches noch Restwärme besitzt, in einen grossen Brauchwassertank geleitet, wo ihm diese mittels Wärmepumpen entzogen und an den Hauptpufferspeicher des Warmwasserbereitungssystems abgegeben wird. Das nun kalte Brauchwasser wird in einen zweiten, extrem grossen unterirdischen Tank geleitet. Dort entzieht es im Winter der Umwelt Energie in Form von Wärme, respektive gibt diese im Sommer ab. Dieser Tank dient als Wärmequelle/senke für die Wärmepumpen des saisonalen Pufferspeichers, sowie als Wärmequelle für den Pufferspeicher der Warmwasserbereitung. Dadurch kann die benötigte Wärmeenergie für das Heizungs-/Kühlungs- und Lüftungssystem saisonal gespeichert und genutzt werden. Die beiden Pufferspeicher dienen dazu, da die Gebäudekomplexe relativ gross sind, die Wärme- und Kälteenergie zwischen zu speichern. Der Transport und die Verteilung der Energie wird mit Klimawärmepumpen bewerkstelligt, bei welchen der Kältekreis umgekehrt werden kann, dadurch kann die Energie, je nach Saison an das modular aufgebaute Heizungs-/Kühl-, Lüftungs- und Warmwasserbereitungssystem abgegeben, respektive aufgenommen werden. Die Warmwasserbereitung wird ganzjährig durch die Solarthermie und in der Wintersaison, durch ein Blockheizkraftwerk unterstützt. Das Blockheizkraftwerk wird mit Biogas, welches aus den biogenen Abfällen der Bewohner erzeugt wird, betrieben. The present paper deals primary with the topic of energy, for this was a literature research carried out. A concept was developed, which results form a combine of renewables energies and different technologies, but also lets nature take its place. This concept is presented by technical drawings, subsequently, the corresponding values of the various systems and facilities were determined through calculations and simulations. The concept consists of two building complexes, which have space for 12’000 people, they are covered with a green façade and roof and surrounded by a pumped storage power station, which is hided through forest. Care was taken, to ensure that different parts of the overall project are multifunctional. That means, that they produce energy, leave space for nature and serve the inhabitants as local recreation area. The building complexes have various photovoltaic systems, which are integrated in the upper south façade and are located on the south roofs, or on the pump storage power plant. The energy, which is produced by the photovoltaic systems during the day, is stored with accumulators/batteries and made it available for the night, that for the whole building floor by floor. Energy surpluses, which are mostly generated by the pump storage power plant, are stored in it as potential energy. This means, that during the day water is pumped up using «solar power», and at night it is converted back into electrical energy with turbines. The two building complexes A+B are divided into three houses, with space for 2’000 persons and each of them has their own heating/cooling, ventilation and hot water preparation system, independent of the other houses. This system consists of heat pumps and ensures, that the heating/cooling, controlled domestic ventilation and hot water preparation system is as climate neutral as possible. For this purpose, the treated domestic waste water, which still has residual heat, is fed into a large service water tank, where the residual heat is extracted by heat pumps and transferred to the main buffer tank of the hot water preparation system. The now cold process water is led into a second very large underground tank, there it extracts in the winter energy from the environment, in the form of heat, or releases it in summer. This tank serves as a heat source or a heat sink for the heat pumps of the seasonal buffer storage, and as a heat source for the buffer tank of the hot water preparation. This allows, the required thermal energy for the heating/cooling and ventilation system, to be stored and used seasonally. The fact that the building complexes are very large, the two buffer storage tanks are used, to store the heating and cooling energy temporarily. The transport and distribution of the energy is done with climate heat pumps, in which the cooling circuit can be reversed. This means that, depending on the season, the energy can be supplied to, or absorbed by the modular heating/cooling, ventilation and hot water preparation system. The hot water preparation system is supported around the year, by solar thermal energy. In the winter season, the hot water preparation system is supported by a cogeneration unit. The cogeneration unit is operated with biogas, which is produced from the biogenic waste of the residents.

Die Europ��ische Union r��umt dieser im Rahmen der 'Energieeffizienz-Richtlinie' gro��e Bedeutung ein, sodass die nationalen Parlamente in der Union entsprechende Ziele zur Erh��hung der Energieeffizienz beschlossen haben. Diese Arbeit beschreibt eine Methode, mit deren Hilfe der Einspareffekt von Energieeffizienzma��nahmen im Geb��udebereich bewertet werden kann. Diese tr��gt dem Umstand Rechnung, dass in Bewertungsprozessen unsichere Einflussgr����en die nach Ma��nahmenumsetzung eingesparte Energiemenge wesentlich beeinflussen k��nnen. Einflussparameter wie die Au��entemperatur oder die Betriebszeit einer Anlage sind nicht ��ber die Lebensdauer einer Ma��nahme vorhersagbar, k��nnen allerdings erheblichen Einfluss auf den Energieverbrauch haben. Daher unterscheidet die vorgestellte Methode zwischen festen, bekannten Einflussparametern, und unsicheren Modellparametern, welchen eine statistische Verteilung zugeordnet wird. Mittels Monte-Carlo-Simulation wird eine Verteilung des Einspareffekts gewonnen, sodass anstelle eines Einzahlwerts ein entsprechendes Intervall das Ergebnis der Bewertung darstellt, was das Ergebnis wesentlich robuster macht. Im Zusammenhang mit Bewertungsmethoden spielen die Definition und Normalisierung des Vergleichsszenarios, der Baseline, eine bedeutende Rolle, was in dieser Arbeit allgemein und anhand von Beispielen diskutiert wird. Im Folgenden wird die Methode zun��chst allgemein beschrieben und anschlie��end ihre Anwendbarkeit im Rahmen von ausgew��hlten Beispielma��nahmen demonstriert. Dabei zeigte sich, dass Modellparametern, welche nicht n��her bekannt sind, aufgrund der Durchf��hrung von Monte-Carlo-Simulationen eine geeignete statistische Verteilung basierend auf realistischen Annahmen zugewiesen werden kann, sodass die Methode selbst bei geringer Datenlage hilfreiche Ergebnisse bereitstellt. Dar��ber hinaus kann mit ihrer Hilfe der Einfluss m��glicher 'Rebound-Effekte' abgesch��tzt werden und es k��nnen jene Einflussparameter erkannt werden, welche ��ber den Einsparerfolg einer Energieeffizienzma��nahme entscheiden. Die behandelten Beispielma��nahmen f��r die betrachtete Geb��udestichprobe w��rden nach Umsetzung in Summe zu einer j��hrlichen Einsparung von rund 1200 t CO2 f��hren. As a consequence of climate protection, dependances on imports of energy resources, limited availability of non-renewable energy carriers and due to economic reasons, energy efficiency has gained in importance. The European Union even emphasizes its importance in a directive leading national parliaments to pass laws to increase energy efficiency. This thesis describes a method to evaluate the achievable energy savings by measures in the building sector. The fact that uncertain factors can significantly affect the calculated amount of saved energy is taken into account by implementation of energy efficiency measures. Influencing quantities, such as outside temperature or the operating time of an energy consuming system, cannot be predicted precisely throughout the lifespan of a measure. Consequently, the introduced method distinguishes between fixed model parameters, which stay the same throughout the simulation and uncertain model parameters, which are identified by an appropriate statistical distribution. Via a Monte-Carlo-Simulation a distribution of the achievable energy savings can be evaluated. Instead of delivering a single quantity, the introduced method provides a range of variations for the expectable energy savings leading to a much more robust result. The specification and normalization of the baseline plays a very important role in the process of evaluating energy savings of an energy efficiency measure, which will be discussed both in general and on the basis of case studies. In the following, the above mentioned method will be described in general and its applicability will be shown using a real dataset of selected buildings. It will be shown that if required model parameters are unknown for a building, it is possible to estimate them using an appropriate statistical distribution and applying it in the Monte-Carlo-Simulations. Consequently, the method leads to useful results even if there is little knowledge of required model parameters. Moreover, the influence of possible ��rebound-effects�� can be estimated as well. Finally, using the method provides information, which influencing quantities have the highest impact on the achievable savings. If all in this thesis presented examples of energy efficiency measures were implemented, about 1200 tons of CO2 emissions could be saved per year.

The potentials of shallow geothermal energy have not been exploited so far, in particular due to the high complexity of planning and approval processes. In addition, the various stakeholders involved in the planning process create interfaces, which can lead to transfer gaps and barriers for an optimized system design. In order to raise the potentials and optimize the system design, a holistic planning process and the combination of different planning tools are necessary, which enable, among other things, geothermal site evaluations, the representation of the mutual thermal influence of geothermal borehole heat exchangers and their effects on neighboring properties, as well as the evaluation of geothermal systems under consideration of economic and ecological decision parameters. In this context, a simulation-based multi-level planning methodology is presented, which enables the holistic planning of geothermal heat pump systems with borehole heat exchangers on the scales of single buildings up to district level in the early planning phases. By integrating calculation tools for mapping the upper ground and subsurface into a closed simulation chain, existing transfer gaps between different trades can be closed. Using a prototypically implemented system configurator, geothermal heat pump systems can be designed in detail, compared with conventional systems, and evaluated on the basis of technical, energetic, economic, and ecological criteria. The combination of configuration, immediate result plotting and automatically triggered simulations running in the background enables an iterative and practical design process. In this context, a heat pump system model is presented which is adapted to the functionalities of the system configurator and specialized for the early planning process. This model includes thermal storage balances and control algorithms, is applicable on city district level and can be coupled bidirectionally to subsurface models. The tool chain's connection to an existing web- and GIS-based geoportal including databases enables a central data aggregation and geothermal site evaluations. This can provide tool-based support for the application and approval process of shallow geothermal systems and holistic planning approaches such as municipal heat planning.

Das Klima in Antalya tritt im Allgemeinen in das mediterrane Klima ein. Die Sommer sind heiß und trocken, die Winter regnerisch und stürmisch. Da Antalya eine Touristenstadt ist, gibt es hier Unmengen an Hotels, die vorwiegend für Großfamilien mit Kindern sind. Dieser Entwurf ist anders als die „herkömmlichen“ Hotelprojekte, die es in Antalya schon gibt. Das Ziel des Entwurfes ist ein Treibhaus- und/oder Gewächshaushotel mit all seinen nachhaltigen Nutzen entlang der Küste zu schaffen. Neben der nachhaltigen Gebäudestruktur des Öko-Hotels werden viele energiesparenden Maßnahmen eingesetzt. Im Fokus stehen hierbei die Verwendung von natürlichen Baumaterialien in monolithischer Bauweise, unterirdische monolithische Betonzisterne für Trink- oder Nutzwasser zur Bewässerung des Innengartens und ebenso eine Meerwassersolaranlage, die als zusätzliches Trinkwasser fungieren soll. Durch Gebäudeintegrierte Photovoltaik-Module (GiPV) an der Fassade und auf dem Dach des Atriums wird die Sonnenenergie genutzt und in Strom zur Erwärmung des Duschwassers umgewandelt. Ein Gebäude, dass nicht nur nimmt, sondern auch gibt! Gegen die Monotonie im Alltag soll das Öko-Hotel eine abwechslungsreiche und beruhigende Entspannung fördern. Als therapeutische Zwecke wird die Thalasso- und Kneipp-Therapie angewendet. Thalasso ist einfach eine Heilbehandlung am und mit dem Meer, aber mit allem, was dazugehört: Wasser, Algen, Schlick, Wind, Salz und frischer, daher schadstoff- und pollenfreier Meeresluft. Einzigartige, heilende Kräfte für Körper und Seele! This diploma thesis describes the idea of designing a sustainable, ecological and economical hotel in Antalya. The climate in Antalya generally enters the Mediterranean climate. Summers are hot and dry, winters are rainy and stormy. Antalya is a tourist city, there are tons of hotels here, which are mainly for large families with children. This design is different from the „conventional“ hotel projects that already exist in Antalya. The aim of the design is to create a greenhouse and/or glasshouse hotel with all its sustainable benefits along the coast. In addition to the sustainable building structure of the eco hotel, many energy-saving measures are used. The focus here is on the use of natural building materials in monolithic construction, underground monolithic concrete cisterns for drinking water or water for other purposes to irrigate the inner garden and also a seawater solar system, which is intended to serve as additional drinking water. Building-integrated photovoltaic modules (BiPV) on the facade and on the roof of the atrium use solar energy and convert it into electricity to heat the shower water. A building that not only takes, but also gives! Against the monotony of everyday life, the eco-hotel is intended to promote varied and soothing relaxation. Thalasso and Kneipp therapy are used for therapeutic purposes. Thalasso is simply a healing treatment by and with the sea, but with everything that goes with it: water, algae, mud, wind, salt and fresh sea air, which is therefore free of pollutants and pollen. Unique, healing powers for body and soul!

Especially in the material handling sector, vehicles with electric drives have gained increasing market acceptance over the past decades. However, the electrification of counterbalanced forklift trucks with high tonnages requires batteries with extended energy capacity. Higher energy capacity usually correlates with higher volume-to-surface ratios resulting in decreased heat dissipation and, therefore, increased average operating temperatures of the commonly used lead acid batteries. As a consequence, battery lifetime is greatly reduced. Without design changes, one possibility for avoiding high operating temperatures is an adapted battery management strategy. This thesis reports on results obtained with flooded lead acid batteries, demonstrating that, with management strategies which include operation in a partial state of charge, energy efficiencies can be increased from about 0.7 to about 0.85 with minimal impact on lifetime.

Damit Unternehmen ihre wirtschaftlichen Tätigkeiten als nachhaltig ausweisen dürfen, müssen sie unter-schiedlichste Kriterien erfüllen, nur eine Anforderung ist bei allen Tätigkeiten dieselbe: die Durchführung einer Klimarisiko- und Vulnerabilitätsanalyse. Mit dieser soll erhoben werden, ob die Geschäftstätigkeit und in weiterem Sinne das Geschäftsmodell klimafit und somit zukunftsfähig ist oder ob Anpassungsmaß-nahmen zur Erhöhung der Anpassungsfähigkeit erforderlich sind, um das Ge-schäft wirtschaftlich nachhaltig, d. h. profitabel zu halten. Die Durchführung von Klimarisiko- und Vulnerabilitätsanalyse ist für Unterneh-men noch großteils unbekanntes Terrain und aktuell existieren noch keine Leit-fäden für Unternehmen, wie sie solche standortbezogenen Analysen zeit- und ressourcenschonend durchführen können. In dieser Arbeit werden daher aus den zwei bekanntesten und umfangreichsten Rahmenwerken für Klimarisiko-analysen die wesentlichen Aspekte herausgearbeitet, um darauf basierend eine Vorgehensweise zu definieren, die Unternehmen als Leitfaden zur Durchfüh-rung eigener Klimarisikoanalysen dienen kann. Zudem wird die erarbeitete Vor-gehensweise am Beispiel eines fiktiven Unternehmens vorgeführt, um vor allem den Umgang mit Klimaszenarien zu demonstrieren und wie die darin enthalte-nen Prognosen für einzelne Klimagefahren interpretiert werden können. Zu gu-ter Letzt wird in dieser Arbeit auch auf Quellen für belastbare Daten und Klimamodelle hingewiesen, wodurch die Durchführung von adäquaten Klimari-sikoanalysen ermöglicht wird, die den Anforderungen der TaxonomieVO Genüge tun. With the Taxonomy Regulation, the EU Commission has for the first time created a classification system for determining when an economic activity of a company can actually be considered sustainable. In order for companies to be allowed to classify their economic activities as sustainable, they must fulfill a wide variety of criteria, but only one requirement is the same for all activities: the performance of a climate risk and vulnerability analysis. The purpose of this is to determine whe-ther the business activity and, in a broader sense, the business model are clima-te-compatible and thus fit for the future, or whether adaptation measures are re-quired to increase adaptive capacity in order to keep the business economically sustainable, i.e. profitable. The performance of climate risk and vulnerability analysis is still largely unknown territory for companies and currently there are no guidelines on how to perform such location-based analyses in a time- and resource-saving manner. In this master thesis, therefore, the essential aspects of the two best-known and most comprehensive frameworks for climate risk analyses are elaborated in order to define a procedure based on them that can serve as a guideline for companies to carry out their own climate risk analyses. In addition, the approach developed is demonstrated using the example of a fictitious company, in order to show how climate scenarios are handled and how the forecasts they contain can be used for a single company. Last but not least, this work also points to sources of robust data and climate models, enabling the performance of adequate climatic risk ana-lyses that meet the requirements of the Taxonomy Regulation.

Angesichts einer drastischen Übernutzung der maritimen Fischbestände wird vielfach ein Übergang zu einer nachhaltigen Fischerei eingefordert. Favorisiert werden häufig Strategien einer Privatisierung und Vermarktlichung der Fangrechte, um einen verantwortungsvollen, nachhaltigen Umgang mit den maritimen Ressourcen zu erreichen. Wie allerdings am Beispiel der Neuordnung der Fischerei in Chile durch das Gesetz "Ley Longueira" im vorliegenden Artikel deutlich gemacht wird, führen diese Strategien zur Verdrängung traditioneller Kleinfischer und sie fördern letztlich eine ökologisch problematische industrielle Fischerei. Unter Bezug auf das sozial-ökologische Leitbild der nachhaltigen Arbeit kann konstatiert werden, dass marktbasierte Strategien zur Erreichung von Nachhaltigkeit in der Fischerei zumeist ihr Ziel verfehlen. Sie verschärfen die sozialen und ökologischen Krisen und legitimieren teilweise Praktiken des Ocean Grabbings. Um eine nachhaltige Arbeit in der Fischerei zu gewährleisten, sind daher gemeinschaftsbasierte Ansätze der Ressourcennutzung zu bevorzugen. In view of the drastic overexploitation of maritime fish stocks, a transition towards a sustainable fishery is required. Strategies of privatization and marketisation of fishing rights are commonly favored in order to achieve a responsible and sustainable management of maritime resources. However, as set out in this article by the example of the reorganization of the fishery by the law "Ley Longueira" in Chile, these strategies often displace traditional small-scale fisheries and ultimately promote an industrial fishery, which is ecologically problematic. As can be argued with reference to the socio-ecological model of "sustainable work", market-based strategies to achieve sustainability in fisheries often fail. They exacerbate the social and ecological crises and legitimize ocean grabbing. To ensure sustainable work in fisheries, community-based approaches to resource use are therefore preferable.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Other literature type 2023Publisher:Unknown Authors: Dehler, Marcel; Dehler, Marcel;Plant protection products are a significant component of conventional arable farming in Germany. They have helped increase land productivity and reduce yield losses, thereby providing a significant contribution to food security. However, plant protection products have negative impacts on biodi-versity. Moreover, their degradation products can be found in ground and surface waters, and they are associated with negative effects on human health. Against this background, the aim of policy is to reduce the use of plant protection products and the associated risks. By contrast, the questions of whether and how farms can adapt their production systems and the resulting costs remain largely unanswered. Similarly, although the advantages and disadvantages of different policy implementation strategies for reducing plant protection products are discussed at both the European and national levels, the scientific publications are aimed primarily at intro-ducing a tax model. A concrete comparison of different policy measures and an assessment of the adaptation reactions as well as the associated consequences, taking agricultural expertise into ac-count, usually is not carried out. Against this background, based on a typical farm in the soil-climate region “Südhannover” and us-ing a focus group approach with farmers and advisors, the present dissertation investigated which farm adaptation measures can reduce the risks to humans and the environment associated with the use of plant protection products by 25 % or 50 % and what adaptation costs result from such measures. The risks posed by pesticides were determined with the help of the Pesticide Load Indi-cator (PLI). In order to be able to quantify the yield effects as a result of reduced pesticide use, regional and national trial evaluations were consulted. In addition, the expected yield effects were differentiated between a best and worst case and a “normal year”. In order to reduce the PLI by 25 %, farmers first will substitute less toxic active substances for those with a higher PLI. Similarly, weeds are increasingly regulated mechanically and non-selective herb-icides are replaced by mechanical tillage before summer crops. If no crop-specific PLI reduction is required and alternative crops are available, farmers will substitute crops with a low net margin per PLI unit used (e.g. rape with grain maize). If the PLI is halved, reduced fungicide and insecticide use across crops or later sowing dates in cereals also are suitable for reducing the risks from plant protection products. With a crop-specific PLI reduction of 25 %, changes in the net margin range from + 25 €/ha for sugar beet to – 60 €/ha for stubble wheat can be expected. If the PLI has to be reduced by 50 % for each individual crop, the range of adjustment costs among the crops increases further. While the PLI can be halved for oilseed rape with costs of about 50 €/ha, the net margin for stubble wheat or winter wheat after silage maize decreases by about 150 €/ha. At farm level, the results show that the more adaptation flexibility farmers are granted, the lower the adaptation costs. With a 25 % reduction of the PLI and taking into account the active ingredient substitution, manageable adaptation costs of between about 10 €/ha and 20 €/ha can be expected, depending on the adaptation flexibility granted. The change in grain units (GU) produced varies between + 4 % and – 5 %. On the other hand, the adjustment costs increase disproportionately strongly with a PLI reduction of 50 %, so that an operational net margin reduction of between about 80 €/ha and a maximum of 125 €/ha can be expected. With a PLI reduction of 50 %, the change in GU produced is between 0 and a maximum of -7 %. As farmers are in competition with their colleagues on the land and tenancy markets, they usually cannot afford to voluntarily switch to production systems that cause lower yields or cost increases and thus put them at a competitive disadvantage vis-à-vis neighbouring farms. Policymakers there-fore must change the framework conditions for all farms in such a way that the adaptation of pro-duction systems is either mandatory or economically viable. A wide range of policy measures are available for this purpose. Following on from the results of the adaptation costs, it therefore was examined how policymakers can use the "PLI" starting point to achieve their reduction target. In order to expose the selected policy measures and impact assessments to the critical judgement of the focus group, four concrete policy measures were developed that can achieve PLI reduction while addressing different secondary objectives. The measures examined include an individual farm PLI ceiling, a licensing system with tradable use rights, a state subsidy for low PLI hectare values and an increase in crop protection product prices depending on PLI. It was assumed that the policy measures would be introduced throughout the European Union. The effects that can be ex-pected on production, farm incomes and the administrative and control costs for farmers and the state were worked out in an impact assessment. The following results emerged: In the case of a PLI ceiling for individual farms and at the same time for individual crops, every farm must, in principle, reduce its PLI use if it does not yet meet the targets in the initial situation. This leads to an area-wide risk reduction without shifting the production of individual crops to third countries. However, the adjustment flexibility for farmers is comparatively low compared with other policy options. The control is carried out with the help of an online database. In contrast, an increase in plant protection prices depending on the PLI has the advantage of not having to control all farms, but only "bottlenecks" such as traders and manufacturers of plant pro-tection products. A disadvantage is the high negative income effect for the farms (> 220 €/ha) if the PLI is halved. In addition, readjustments of the levy level are to be expected in order to ap-proach the reduction target. If the PLI use rights are distributed in a licensing system depending on acreage, it can be expected that crops with a high net margin per PLI unit used will be cultivated preferentially. On the other hand, crops with a low net margin per PLI unit used will increasingly be pushed out of cultivation. Farm managers can decide on the basis of the market price for the tradable PLI use rights whether to use them themselves on the farm or sell them on the market. As a result, it is to be expected that PLI units will be saved, especially on marginal arable sites where this saving causes only low costs. The PLI units freed up there move primarily to regions where an above-average net margin per PLI unit can be produced. These are classically favourable locations for arable farming. The comparatively high administrative costs required for tradability must be viewed critically. For the state, this additional effort goes hand in hand with the advantage that the reduction target can be targeted precisely. If the state decides to promote low PLI hectare values with a premium, a negative income effect at farm level can be prevented, as the farm only participates if its costs are lower than the premium payment. The acceptance of the policy measure by farmers is high. A major challenge, however, is the controllability, as there are high incentives to undermine the system. DOI:10.3220/REP1678173967000

Das Wissen um die endliche Verfügbarkeit konventioneller, fossiler Rohstoffe führte zur intensivierten Auseinandersetzung mit alternativen, erneuerbaren Energiequellen. Im Zuge dieses als Energiewende bezeichneten Prozesses hat die thermische Nutzung des Untergrundes als Speicher, aber auch als Quelle von Wärme deutlich zugenommen. Diese Entwicklung verstärkte die Forschungsbestrebungen für die Beschreibung thermischer Parameter des Untergrundes sowie der Bauwerke, die zur Wärmegewinnung genutzt werden, über Temperaturverteilungen während Installation und Betrieb. Die zugehörigen Temperaturmessungen können dafür zeitgemäß, kostengünstig und unaufwendig mit Ramanspektrum basierter, verteilter Temperaturmessung auf Glasfaserkabeln (DTS) durchgeführt werden. In der vorliegenden Arbeit wurde vom aktuellen, erkundungsbezogenen Stand der Technik aus, dem Thermal-Response-Test, untersucht, inwieweit eine Vergleichbarkeit zwischen unterschiedlichen Erdwärmesonden eines Sondenfeldes gegeben ist und diese Ergebnisse auch nicht etablierten, tiefenaufgelösten TRT gegenübergestellt. Aufgrund der Notwendigkeit der Verfügbarkeit von Erdwärmesonden zur TRT-Durchführung wurde sich entsprechend auch mit alternativen Erkundungsmöglichkeiten auseinandergesetzt. Dafür wurde sich mit der Temperaturcharakterisierung von flachem Untergrund sowie der Erdwärmesonde (EWS) beschäftigt. Temperaturmessungen während Aufheizen und Abkühlen des Untergrunds wurden mit DTS durchgeführt und alternativen Erkundungsverfahren, wie Direct-Push, gegenübergestellt. In Kombination mit den TRT-Temperaturverteilungen zeigte sich dabei, dass nicht nur geologische Schichten unterschieden werden können, sondern auch, dass der Ausbau der Erdwärmesonde einen erkennbaren Einfluss auf die Messungen hat. Aus diesem Grund wurden die Arbeiten mit Untersuchungen zur Nutzung der Hydrationswärme als Werkzeug des Qualitätsmanagements von EWS abgeschlossen. Dabei wurde auf numerische Wärmeleitungsmodellierung, Laborversuche und Feldversuche zurückgegriffen. Aus der Summe der Ergebnisse wurden unterschiedliche Erklärungsansätze abgeleitet, welche notwendig sind für die Abschätzung, inwieweit die gefundenen Beobachtungen zur Erkundung und zum Qualitätsmanagement von Erdwärmesonden beitragen können. Dabei zeigte sich, dass verteilte Temperaturmessungen im Allgemeinen gut dazu geeignet sind, das relative Wärmespeichervermögen des Untergrundes zu ermitteln sowie mögliche Fehlstellen in der Hinterfüllung einer EWS zu detektieren. Damit kann die Temperaturmessung innerhalb einer EWS dazu genutzt werden, künftige Nutzungsarten zu definieren und die EWS vom Einbau an auf ihre Qualität zu überprüfen. Die Ankopplung dieser Versuche an herkömmliche Verfahren wie den Thermal-Response-Test hat sich bewährt, aber auch gezeigt, dass die Ergebnisse, die in TRT ermittelt werden, stark von den Einbaubedingungen der EWS abhängen. Eine direkter Vergleich von unterschiedlichen TRT eines EWS-Feldes (quartäre Sedimente, Sand, Kies, Schluff) wirft dabei Fragen zur Übertragbarkeit von TRT-Ergebnissen auf Nachbarsonden auf, die nicht abschließend geklärt werden konnten. Alle Temperaturdaten aus den Experimenten können von den Archivservern des Helmholtz-Zentrums für Umweltforschung (UFZ) bezogen werden. Die Ordner-Struktur des Archivs ist in Appendix A dargestellt. Zusätzlich sind die Daten der angesprochenen Publikationen hinterlegt. Link: https://www.ufz.de/record/dmp/archive/6446/de/.

The knowledge about the limited availability of conventional, fossil energy resources directed the focus on alternative, renewable energy resources. In the course of this energy transition, there is an increased use of the shallow subsurface for thermal energy mining and storage. This increase in use led to deeper research in the field of characterisation of thermal properties of the (shallow) subsurface as well as investigations in related thermal energy mining systems like borehole ground heat exchanger (BHE). Hereby, temperature evolution during operation or exploration of the BHE with thermal response tests (TRT) were of special interest. Respective measurements can be done by Raman-spectre based distributed temperature sensing (DTS). In the presented work the actual standard tool for geothermal exploration, the TRT, is the basis for further investigation. Here, the comparability between TRTs of different BHE at the same test site is of special interest as well as the comparison to the not widely established enhanced (depth depending) TRT. As the TRT itself is in need of a BHE, approaches more easy to apply were also investigated. To achieve the mentioned points, temperature evolution was measured with the help of DTS within the subsurface as well as within BHE. This was done during heating and cooling phases and partially compared to alternative exploration data like various Direct-Push (DP) techniques. The analysis of the temperature distributions showed not only that different geological layers can be distinguished during exploration phase but also that the construction process and quality have a measurable impact on the results. This led to investigations of the usability of hydration heat for BHE quality management by field site temperature measurements as well as laboratory and numeric analysis. From the sum of the results multiple explanations were deduced which help to understand how the results of the exploration and the quality management approaches can help in determining the type of use of future BHE projects. Furthermore, it was shown that distributed temperature measurements are generally well suited for deduction of subsurface relative thermal storage potential as well as detection of possible failures within the grouting of a BHE. Temperature measurements in BHE can therefore be used to define the future thermal usage of the subsurface as well as help detecting failures of the BHE from installation onwards. Combining those approaches with conventional TRT was successful. However, it could be shown that the results of TRT strongly depend on BHE installation procedure. It is also shown that the direct comparison of different BHE from the same field site (quarternary sediments, sand gravel, tilt) shows varying results, leading to questions about the comparability of TRT of adjacent BHE which could not finally be resolved. The data of all experiments is stored at the science-server of the Helmholtz-Centre for Environmental Research (UFZ). The folder structure of the server can be found in appendix A.

Die vorliegende Arbeit befasst sich hauptsächlich mit dem Thema Energie, dazu wurde eine Literaturrecherche durchgeführt. Es wurde ein Konzept erarbeitet, welches aus einem Zusammenschluss erneuerbarer Energien und verschiedenen Technologien besteht, aber auch der Natur ihren Platz zugesteht. Dieses Konzept wird mittels technischer Zeichnungen dargestellt, anschliessend wurden, durch Berechnungen und Simulationen, die dazugehörigen Werte der verschiedenen Systeme und Anlagen ermittelt. Das Konzept besteht aus zwei Gebäudekomplexen die Platz für zirka 12'000 Personen bieten, sie sind mit einer Fassaden- und Dachbegrünung ausgestattet und von einem Pumpspeicherkraftwerk, welches durch einen Wald kaschiert wird, umgeben. Es wurde darauf geachtet, dass verschiedene Anlageteile des Gesamtprojekts multifunktionell sind, das heisst Energie produzieren, Platz für die Natur lassen und den Bewohnern als Naherholungsgebiet dienen. Die Gebäudekomplexe besitzen verschiedene Photovoltaikanlagen, welche in den oberen Südfassaden integriert wurden, sich auf den Süddächern oder auf dem Pumpspeicherkraftwerk befinden. Die tagsüber durch die Photovoltaik erzeugte Energie, wird in den Gebäuden etagenweise mittels Akkus/Batterien gespeichert und für die Nacht verfügbar gemacht. Energieüberschüsse, welche mehrheitlich durch die Photovoltaikanlage des Pumpspeicherkraftwerkes erzeugt wurden, werden in diesem als potentielle Energie gespeichert. Das heisst am Tag wird Wasser mittels «Solarstrom» hochgepumpt und in der Nacht mittels Turbinen wieder in elektrische Energie umgewandelt. Die zwei Gebäudekomplexe A+B, sind jeweils in drei Häuser für rund 2'000 Personen gegliedert und besitzen ein eigenes, von den anderen Häusern unabhängiges, Heizungs-/Kühlungs-, Lüftungs- und Warmwasserbereitungssystem. Dieses System besteht aus Wärmepumpen und sorgt dafür, dass die Heizung/Kühlung, Kontrollierte Wohnungslüftung, sowie die Warmwasserbereitung pro Haus möglichst «klimaneutral» betrieben werden. Dazu wird das aufbereitete Hausabwasser, welches noch Restwärme besitzt, in einen grossen Brauchwassertank geleitet, wo ihm diese mittels Wärmepumpen entzogen und an den Hauptpufferspeicher des Warmwasserbereitungssystems abgegeben wird. Das nun kalte Brauchwasser wird in einen zweiten, extrem grossen unterirdischen Tank geleitet. Dort entzieht es im Winter der Umwelt Energie in Form von Wärme, respektive gibt diese im Sommer ab. Dieser Tank dient als Wärmequelle/senke für die Wärmepumpen des saisonalen Pufferspeichers, sowie als Wärmequelle für den Pufferspeicher der Warmwasserbereitung. Dadurch kann die benötigte Wärmeenergie für das Heizungs-/Kühlungs- und Lüftungssystem saisonal gespeichert und genutzt werden. Die beiden Pufferspeicher dienen dazu, da die Gebäudekomplexe relativ gross sind, die Wärme- und Kälteenergie zwischen zu speichern. Der Transport und die Verteilung der Energie wird mit Klimawärmepumpen bewerkstelligt, bei welchen der Kältekreis umgekehrt werden kann, dadurch kann die Energie, je nach Saison an das modular aufgebaute Heizungs-/Kühl-, Lüftungs- und Warmwasserbereitungssystem abgegeben, respektive aufgenommen werden. Die Warmwasserbereitung wird ganzjährig durch die Solarthermie und in der Wintersaison, durch ein Blockheizkraftwerk unterstützt. Das Blockheizkraftwerk wird mit Biogas, welches aus den biogenen Abfällen der Bewohner erzeugt wird, betrieben. The present paper deals primary with the topic of energy, for this was a literature research carried out. A concept was developed, which results form a combine of renewables energies and different technologies, but also lets nature take its place. This concept is presented by technical drawings, subsequently, the corresponding values of the various systems and facilities were determined through calculations and simulations. The concept consists of two building complexes, which have space for 12’000 people, they are covered with a green façade and roof and surrounded by a pumped storage power station, which is hided through forest. Care was taken, to ensure that different parts of the overall project are multifunctional. That means, that they produce energy, leave space for nature and serve the inhabitants as local recreation area. The building complexes have various photovoltaic systems, which are integrated in the upper south façade and are located on the south roofs, or on the pump storage power plant. The energy, which is produced by the photovoltaic systems during the day, is stored with accumulators/batteries and made it available for the night, that for the whole building floor by floor. Energy surpluses, which are mostly generated by the pump storage power plant, are stored in it as potential energy. This means, that during the day water is pumped up using «solar power», and at night it is converted back into electrical energy with turbines. The two building complexes A+B are divided into three houses, with space for 2’000 persons and each of them has their own heating/cooling, ventilation and hot water preparation system, independent of the other houses. This system consists of heat pumps and ensures, that the heating/cooling, controlled domestic ventilation and hot water preparation system is as climate neutral as possible. For this purpose, the treated domestic waste water, which still has residual heat, is fed into a large service water tank, where the residual heat is extracted by heat pumps and transferred to the main buffer tank of the hot water preparation system. The now cold process water is led into a second very large underground tank, there it extracts in the winter energy from the environment, in the form of heat, or releases it in summer. This tank serves as a heat source or a heat sink for the heat pumps of the seasonal buffer storage, and as a heat source for the buffer tank of the hot water preparation. This allows, the required thermal energy for the heating/cooling and ventilation system, to be stored and used seasonally. The fact that the building complexes are very large, the two buffer storage tanks are used, to store the heating and cooling energy temporarily. The transport and distribution of the energy is done with climate heat pumps, in which the cooling circuit can be reversed. This means that, depending on the season, the energy can be supplied to, or absorbed by the modular heating/cooling, ventilation and hot water preparation system. The hot water preparation system is supported around the year, by solar thermal energy. In the winter season, the hot water preparation system is supported by a cogeneration unit. The cogeneration unit is operated with biogas, which is produced from the biogenic waste of the residents.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Other literature type 2016Publisher:TU Wien Authors: Schl��gl, Klemens;Das Themenfeld 'Energieeffizienz' gewinnt aus Gr��nden des Klimaschutzes, der Importabh��ngigkeit von Energietr��gern, der Beschr��nktheit bestimmter Rohstoffe und aus wirtschaftlichen Gr��nden immer mehr an Bedeutung. Die Europ��ische Union r��umt dieser im Rahmen der 'Energieeffizienz-Richtlinie' gro��e Bedeutung ein, sodass die nationalen Parlamente in der Union entsprechende Ziele zur Erh��hung der Energieeffizienz beschlossen haben. Diese Arbeit beschreibt eine Methode, mit deren Hilfe der Einspareffekt von Energieeffizienzma��nahmen im Geb��udebereich bewertet werden kann. Diese tr��gt dem Umstand Rechnung, dass in Bewertungsprozessen unsichere Einflussgr����en die nach Ma��nahmenumsetzung eingesparte Energiemenge wesentlich beeinflussen k��nnen. Einflussparameter wie die Au��entemperatur oder die Betriebszeit einer Anlage sind nicht ��ber die Lebensdauer einer Ma��nahme vorhersagbar, k��nnen allerdings erheblichen Einfluss auf den Energieverbrauch haben. Daher unterscheidet die vorgestellte Methode zwischen festen, bekannten Einflussparametern, und unsicheren Modellparametern, welchen eine statistische Verteilung zugeordnet wird. Mittels Monte-Carlo-Simulation wird eine Verteilung des Einspareffekts gewonnen, sodass anstelle eines Einzahlwerts ein entsprechendes Intervall das Ergebnis der Bewertung darstellt, was das Ergebnis wesentlich robuster macht. Im Zusammenhang mit Bewertungsmethoden spielen die Definition und Normalisierung des Vergleichsszenarios, der Baseline, eine bedeutende Rolle, was in dieser Arbeit allgemein und anhand von Beispielen diskutiert wird. Im Folgenden wird die Methode zun��chst allgemein beschrieben und anschlie��end ihre Anwendbarkeit im Rahmen von ausgew��hlten Beispielma��nahmen demonstriert. Dabei zeigte sich, dass Modellparametern, welche nicht n��her bekannt sind, aufgrund der Durchf��hrung von Monte-Carlo-Simulationen eine geeignete statistische Verteilung basierend auf realistischen Annahmen zugewiesen werden kann, sodass die Methode selbst bei geringer Datenlage hilfreiche Ergebnisse bereitstellt. Dar��ber hinaus kann mit ihrer Hilfe der Einfluss m��glicher 'Rebound-Effekte' abgesch��tzt werden und es k��nnen jene Einflussparameter erkannt werden, welche ��ber den Einsparerfolg einer Energieeffizienzma��nahme entscheiden. Die behandelten Beispielma��nahmen f��r die betrachtete Geb��udestichprobe w��rden nach Umsetzung in Summe zu einer j��hrlichen Einsparung von rund 1200 t CO2 f��hren. As a consequence of climate protection, dependances on imports of energy resources, limited availability of non-renewable energy carriers and due to economic reasons, energy efficiency has gained in importance. The European Union even emphasizes its importance in a directive leading national parliaments to pass laws to increase energy efficiency. This thesis describes a method to evaluate the achievable energy savings by measures in the building sector. The fact that uncertain factors can significantly affect the calculated amount of saved energy is taken into account by implementation of energy efficiency measures. Influencing quantities, such as outside temperature or the operating time of an energy consuming system, cannot be predicted precisely throughout the lifespan of a measure. Consequently, the introduced method distinguishes between fixed model parameters, which stay the same throughout the simulation and uncertain model parameters, which are identified by an appropriate statistical distribution. Via a Monte-Carlo-Simulation a distribution of the achievable energy savings can be evaluated. Instead of delivering a single quantity, the introduced method provides a range of variations for the expectable energy savings leading to a much more robust result. The specification and normalization of the baseline plays a very important role in the process of evaluating energy savings of an energy efficiency measure, which will be discussed both in general and on the basis of case studies. In the following, the above mentioned method will be described in general and its applicability will be shown using a real dataset of selected buildings. It will be shown that if required model parameters are unknown for a building, it is possible to estimate them using an appropriate statistical distribution and applying it in the Monte-Carlo-Simulations. Consequently, the method leads to useful results even if there is little knowledge of required model parameters. Moreover, the influence of possible ��rebound-effects�� can be estimated as well. Finally, using the method provides information, which influencing quantities have the highest impact on the achievable savings. If all in this thesis presented examples of energy efficiency measures were implemented, about 1200 tons of CO2 emissions could be saved per year.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Doctoral thesis 2023Embargo end date: 18 Sep 2023 GermanyPublisher:RWTH Aachen University Authors: Weck-Ponten, Sebastian;In future, heat pumps and shallow geothermal energy will play a central role in the decarbonization of the building and energy sector. The potentials of shallow geothermal energy have not been exploited so far, in particular due to the high complexity of planning and approval processes. In addition, the various stakeholders involved in the planning process create interfaces, which can lead to transfer gaps and barriers for an optimized system design. In order to raise the potentials and optimize the system design, a holistic planning process and the combination of different planning tools are necessary, which enable, among other things, geothermal site evaluations, the representation of the mutual thermal influence of geothermal borehole heat exchangers and their effects on neighboring properties, as well as the evaluation of geothermal systems under consideration of economic and ecological decision parameters. In this context, a simulation-based multi-level planning methodology is presented, which enables the holistic planning of geothermal heat pump systems with borehole heat exchangers on the scales of single buildings up to district level in the early planning phases. By integrating calculation tools for mapping the upper ground and subsurface into a closed simulation chain, existing transfer gaps between different trades can be closed. Using a prototypically implemented system configurator, geothermal heat pump systems can be designed in detail, compared with conventional systems, and evaluated on the basis of technical, energetic, economic, and ecological criteria. The combination of configuration, immediate result plotting and automatically triggered simulations running in the background enables an iterative and practical design process. In this context, a heat pump system model is presented which is adapted to the functionalities of the system configurator and specialized for the early planning process. This model includes thermal storage balances and control algorithms, is applicable on city district level and can be coupled bidirectionally to subsurface models. The tool chain's connection to an existing web- and GIS-based geoportal including databases enables a central data aggregation and geothermal site evaluations. This can provide tool-based support for the application and approval process of shallow geothermal systems and holistic planning approaches such as municipal heat planning.

Das Klima in Antalya tritt im Allgemeinen in das mediterrane Klima ein. Die Sommer sind heiß und trocken, die Winter regnerisch und stürmisch. Da Antalya eine Touristenstadt ist, gibt es hier Unmengen an Hotels, die vorwiegend für Großfamilien mit Kindern sind. Dieser Entwurf ist anders als die „herkömmlichen“ Hotelprojekte, die es in Antalya schon gibt. Das Ziel des Entwurfes ist ein Treibhaus- und/oder Gewächshaushotel mit all seinen nachhaltigen Nutzen entlang der Küste zu schaffen. Neben der nachhaltigen Gebäudestruktur des Öko-Hotels werden viele energiesparenden Maßnahmen eingesetzt. Im Fokus stehen hierbei die Verwendung von natürlichen Baumaterialien in monolithischer Bauweise, unterirdische monolithische Betonzisterne für Trink- oder Nutzwasser zur Bewässerung des Innengartens und ebenso eine Meerwassersolaranlage, die als zusätzliches Trinkwasser fungieren soll. Durch Gebäudeintegrierte Photovoltaik-Module (GiPV) an der Fassade und auf dem Dach des Atriums wird die Sonnenenergie genutzt und in Strom zur Erwärmung des Duschwassers umgewandelt. Ein Gebäude, dass nicht nur nimmt, sondern auch gibt! Gegen die Monotonie im Alltag soll das Öko-Hotel eine abwechslungsreiche und beruhigende Entspannung fördern. Als therapeutische Zwecke wird die Thalasso- und Kneipp-Therapie angewendet. Thalasso ist einfach eine Heilbehandlung am und mit dem Meer, aber mit allem, was dazugehört: Wasser, Algen, Schlick, Wind, Salz und frischer, daher schadstoff- und pollenfreier Meeresluft. Einzigartige, heilende Kräfte für Körper und Seele! This diploma thesis describes the idea of designing a sustainable, ecological and economical hotel in Antalya. The climate in Antalya generally enters the Mediterranean climate. Summers are hot and dry, winters are rainy and stormy. Antalya is a tourist city, there are tons of hotels here, which are mainly for large families with children. This design is different from the „conventional“ hotel projects that already exist in Antalya. The aim of the design is to create a greenhouse and/or glasshouse hotel with all its sustainable benefits along the coast. In addition to the sustainable building structure of the eco hotel, many energy-saving measures are used. The focus here is on the use of natural building materials in monolithic construction, underground monolithic concrete cisterns for drinking water or water for other purposes to irrigate the inner garden and also a seawater solar system, which is intended to serve as additional drinking water. Building-integrated photovoltaic modules (BiPV) on the facade and on the roof of the atrium use solar energy and convert it into electricity to heat the shower water. A building that not only takes, but also gives! Against the monotony of everyday life, the eco-hotel is intended to promote varied and soothing relaxation. Thalasso and Kneipp therapy are used for therapeutic purposes. Thalasso is simply a healing treatment by and with the sea, but with everything that goes with it: water, algae, mud, wind, salt and fresh sea air, which is therefore free of pollutants and pollen. Unique, healing powers for body and soul!

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Doctoral thesis 2018 GermanyAuthors: Büngeler, Johannes;The replacement of internal combustion engines by electric motors has been identified as a way to achieve widely-accepted international climate protection goals. Especially in the material handling sector, vehicles with electric drives have gained increasing market acceptance over the past decades. However, the electrification of counterbalanced forklift trucks with high tonnages requires batteries with extended energy capacity. Higher energy capacity usually correlates with higher volume-to-surface ratios resulting in decreased heat dissipation and, therefore, increased average operating temperatures of the commonly used lead acid batteries. As a consequence, battery lifetime is greatly reduced. Without design changes, one possibility for avoiding high operating temperatures is an adapted battery management strategy. This thesis reports on results obtained with flooded lead acid batteries, demonstrating that, with management strategies which include operation in a partial state of charge, energy efficiencies can be increased from about 0.7 to about 0.85 with minimal impact on lifetime.

Damit Unternehmen ihre wirtschaftlichen Tätigkeiten als nachhaltig ausweisen dürfen, müssen sie unter-schiedlichste Kriterien erfüllen, nur eine Anforderung ist bei allen Tätigkeiten dieselbe: die Durchführung einer Klimarisiko- und Vulnerabilitätsanalyse. Mit dieser soll erhoben werden, ob die Geschäftstätigkeit und in weiterem Sinne das Geschäftsmodell klimafit und somit zukunftsfähig ist oder ob Anpassungsmaß-nahmen zur Erhöhung der Anpassungsfähigkeit erforderlich sind, um das Ge-schäft wirtschaftlich nachhaltig, d. h. profitabel zu halten. Die Durchführung von Klimarisiko- und Vulnerabilitätsanalyse ist für Unterneh-men noch großteils unbekanntes Terrain und aktuell existieren noch keine Leit-fäden für Unternehmen, wie sie solche standortbezogenen Analysen zeit- und ressourcenschonend durchführen können. In dieser Arbeit werden daher aus den zwei bekanntesten und umfangreichsten Rahmenwerken für Klimarisiko-analysen die wesentlichen Aspekte herausgearbeitet, um darauf basierend eine Vorgehensweise zu definieren, die Unternehmen als Leitfaden zur Durchfüh-rung eigener Klimarisikoanalysen dienen kann. Zudem wird die erarbeitete Vor-gehensweise am Beispiel eines fiktiven Unternehmens vorgeführt, um vor allem den Umgang mit Klimaszenarien zu demonstrieren und wie die darin enthalte-nen Prognosen für einzelne Klimagefahren interpretiert werden können. Zu gu-ter Letzt wird in dieser Arbeit auch auf Quellen für belastbare Daten und Klimamodelle hingewiesen, wodurch die Durchführung von adäquaten Klimari-sikoanalysen ermöglicht wird, die den Anforderungen der TaxonomieVO Genüge tun. With the Taxonomy Regulation, the EU Commission has for the first time created a classification system for determining when an economic activity of a company can actually be considered sustainable. In order for companies to be allowed to classify their economic activities as sustainable, they must fulfill a wide variety of criteria, but only one requirement is the same for all activities: the performance of a climate risk and vulnerability analysis. The purpose of this is to determine whe-ther the business activity and, in a broader sense, the business model are clima-te-compatible and thus fit for the future, or whether adaptation measures are re-quired to increase adaptive capacity in order to keep the business economically sustainable, i.e. profitable. The performance of climate risk and vulnerability analysis is still largely unknown territory for companies and currently there are no guidelines on how to perform such location-based analyses in a time- and resource-saving manner. In this master thesis, therefore, the essential aspects of the two best-known and most comprehensive frameworks for climate risk analyses are elaborated in order to define a procedure based on them that can serve as a guideline for companies to carry out their own climate risk analyses. In addition, the approach developed is demonstrated using the example of a fictitious company, in order to show how climate scenarios are handled and how the forecasts they contain can be used for a single company. Last but not least, this work also points to sources of robust data and climate models, enabling the performance of adequate climatic risk ana-lyses that meet the requirements of the Taxonomy Regulation.
