V diplomskem delu so, na podlagi literature, analizirane dinamične lastnosti različnih tipov vetrnih elektrarn v elektroenergetskem sistemu. Namen dela je ponuditi pregled generacije vetrne energije, pri katerem je poudarek na vplivu vetrnih elektrarn na stabilnost elektroenergetskega sistema. Podani so osnovni mehanizmi delovanja asinhronskega generatorja, dvojno napajanega asinhronskega generatorja in sinhronskega generatorja s pretvornikom, njihovo tranzientno obratovanje in zmožnost dušenja oscilacij. Predstavljen je tudi stabilizator moči, ki z dodatno regulacijo vpliva na obratovanje elektroenergetskega sistema. Na izbranem modelu omrežja je prikazan vpliv različnih tipov vetrnih elektrarn na tranzientno stabilnost in dušenje elektroenergetskega sistema. Generatorji se različno odzivajo glede na njihovo obremenitev. Vsi so stabilni pri nizkih obremenitvah. Pri visokih obremenitvah pa se asinhrosnki generator in sinhronski generator s pretvornikom izkažeta kot tranzientno n This thesis describes the dynamic characteristcs of different types of wind turbines in the power grid. Its purpose is to offer an overview on wind energy generation with an emphasis on the impact of wind generation on the power system stability. The work describes the basic mechanical principles of fixed-speed induction generators, doubly fed induction generators and fully rated converter wind turbines using synchronous generators, their tranzient performance and damping. Also presented, is the power system stabilazer, which offers additional control on power system performance. The impact of different types of wind turbines on the network tranzient stability and damping is also shown in a generic test network. Generators behave differently based on their capacity. All generators are stable at low capacities. Induction generator and fully rated converter wind turbine using synchronous generator are unstable at high capacities. Power system stabilizer improves the stability of bot

In Slovenia, the production of electricity from the wind is neglected, or this share is very small. Major wind farm projects are fairly expensive and hindered by bureaucracy, and the wind situation is not the most favorable, only a small part of the territory of Slovenia is favorable for the installation of major wind power plants. Therefore, it is necessary to concentrate on projects of wind farms up to 20 kW. Within the diploma work, a detailed overview of literature and the market, which forms the basis for the design of wind power plants of small power and a review of existing and possible new construction solutions. At the designing a wind power plant is complyed the requirements and provisions of the applicable standards and regulations, and requirements and criteria for assembly and maintenance. At the design of the wind power plant is complyed wind conditions in Slovenia. In the framework of the diploma will be prepared the proposal of structural solutions, which according to the technical and economic criteria will be adequately evaluated and the optimal design chosen, as the documentation, an integrated drawing of the concept of a wind power plant is attached. V Sloveniji je proizvodnja električne energije iz vetra zanemarjena oziroma je ta delež zelo majhen. Projekti večjih vetrnih elektrarn so precej dragi in ovirani s strani birokracije, pa še vetrne razmere niso najbolj ugodne, saj je le majhen del območja Slovenije ugoden za postavitev večjih vetrnih elektrarn. Zato se je treba skoncentrirati na projekte vetrnih elektrarn do 20 kW. V okviru diplomskega dela je narejen podroben pregled literature in trga, ki predstavlja osnovo pri snovanju vetrnih elektrarn manjših moči, ter pregled obstoječih in možnih novih konstrukcijskih rešitev. Pri zasnovi vetrne elektrarne so upoštevane zahteve in določila veljavnih standardov in predpisov ter zahteve in kriteriji za montažo in vzdrževanje. Pri zasnovi vetrne elektrarne so upoštevane vetrovne razmere v Sloveniji. V okviru diplomskega dela bo pripravljen predlog konstrukcijskih rešitev, ki bodo glede na tehnične in ekonomske kriterije ustrezno ovrednotene, ter izbrana optimalna zasnova kot dokumentacija, ki je priložena kot sestavna risba koncepta vetrne elektrarne.

In the following thesis, we discussed aspects of sustainable design in construction. We presented the principles and indicators of sustainable construction, recognized by the profession. We introduced the concept of integrated planning, which is a relatively new approach to designing of the buildings using BIM. Integrated design is embraced in the BIM design itself, as a holistic approach to building construction, as will be described below. We also described how the software actually verifies environmental aspects such as the orientation of the object, the shape of the building, daylight, energy analysis, collecting rain water and materials. In the practical part of the thesis, we first define the location of the building. Accordingly, we adjusted the type of construction, which should be from environmentally friendly materials that are suitable and efficient for use in Slovenia. Wrapping of the buildng and foundations were adapted to wooden supporting structure, we took into account also the size and intended use of the building. Through the programs we have determined the optimum orientation of the object. This was followed by construction of the object in ArchiCAD BIM software program. We have created a building information model, where we performed energy analysis. The results were compared with results which we got out with program called Knaufinsulation Energy. Finally, the analysis of illumination in specific area, we performed in the program called Velux. With this we demonstrated the potential use of computer tools as to assist in the planning of buildings with minimum burden on the environment, and taking into account the user's comfort. V diplomski nalogi smo obravnavali vidike trajnostnega načrtovanja v gradbeništvu. Predstavili smo načela in indikatorje trajnostne gradnje, ki jih priznava stroka. Predstavili smo tudi koncept integralnega načrtovanja, ki je dokaj nov pristop k projektiranju objektov s pomočjo orodij BIM (angl. Building Information Modelling). Integralno načrtovanje je zaobjeto tudi v samem BIM projektiranju, ki nudi celovit pristop h gradnji stavb. Opisali smo tudi, kako s programsko opremo konkretno preverimo okoljske vidike, kot so: orientacija objekta, oblika stavbe, dnevna svetloba, energetska analiza, zbiranje meteorne vode in materiali. V praktičnem delu diplomske naloge smo najprej definirali lokacijo objekta. Temu smo prilagodili tip gradnje, ki je moral biti iz okolju prijaznih materialov, ki so primerni in smotrni za uporabo v Sloveniji. Ovoj stavbe in temeljenje smo prilagodili leseni nosilni konstrukciji, upoštevali smo tudi velikost in namembnost objekta. S pomočjo programov smo določili najbolj optimalno orientiranost objekta. Sledila je izdelava objekta v BIM računalniškem programu ArchiCAD. Izdelali smo informacijski model stavbe, kjer smo izvedli energetske analize. Rezultate smo primerjali z rezultati iz programa Knaufinsulation Energija. Končno analizo osvetljenosti konkretnega prostora pa smo izvedli v programu Velux. S tem smo prikazali možnosti uporabe računalniških orodij kot pomoč pri načrtovanju objektov s čim manjšo obremenitvijo okolja ter upoštevajoče ugodje uporabnikov.

0.5 g/L and 1.0 g/L. We took notes of daily water usage and statistically processed the data with a computer, using Microsoft Excel 2010, where we tried to figure out the differences by analysis of variance (ANOVA). With the computer program SPSS 17.0, we used t-test for determination of difference characteristics and Pearson's correlation coefficient for analysis of connectedness. We calculated the level of normalized relative transpiration (the NRT) from absolute water consumption. At the end of the experiment, we measured height, thickness of the shoots and counted the number of shoots and made a graphic comparison between them. The results: The clone V160 used most of water with all concentrations of NaCl. In clone V093, NRT was the highest with the NaCl concentration of 1.0 g/L, in clone V160 at concentration 0,2 and 0.5 g/L, and in clone V052 at concentration 0.5 g/L. In clone V052, at NaCl concentration of 0.2 g/L, NRT was less than 100% from the beginning of the experiment. Discussion and conclusion: In our experiment, NaCl did not pile up in the ground to such extent that it would slow down the transpiration and affect the growth of willow trees. Based on the obtained results, we can expect that in S. alba clones V093, V160 and V052 it would not come to effects of NaCl on the efficiency of treatment of urban wastewater in real ETS at a concentration of NaCl up to 1.0 g/L in 1 vegetative period. We assume that the results in real ETS could differ from ours, because we did not use wastewater that could boost the uptake of water and speed up the accumulation of NaCl. In addition, it would make sense to monitor the response of willow trees and the interaction of various factors on the growth of willow trees during more vegetative periods. 0,5 g/L in 1,0 g/L. Beležili smo dnevno porabo vode in podatke statistično obdelali z računalniškim programom Microsoft Excel 2010, kjer smo razlike ugotavljali z analizo variance (ANOVA). Z računalniškim programom SPSS Statistics 17.0 smo za ugotavljanje značilnosti razlik uporabili t-test in za analizo povezanosti Pearsonov korelacijski koeficient. Iz absolutne porabe vode smo izračunali stopnjo normalizirane relativne transpiracije (NRT). Na koncu poskusa smo izmerili višino, debelino poganjkov, prešteli število poganjkov in naredili grafično primerjavo med njimi. Rezultati: Klon V160 je pri vseh koncentracijah NaCl porabil največ vode. Pri klonu V093 je bila največja NRT pri koncentraciji NaCl 1,0 g/L, pri klonu V160 pri koncentraciji 0,2 in 0,5 g/L in pri klonu V052 pri koncentraciji 0,5 g/L. Pri klonu V052 je bila NRT pri koncentraciji NaCl 0,2 g/L od začetka poskusa nižja od 100 %. Razprava in sklep: V našem poskusu se NaCl ni nakopičil v zemljo do te mere, da bi zaviral transpiracijo in vplival na rast vrb. Na podlagi pridobljenih rezultatov lahko pričakujemo, da pri klonih vrbe S. alba V093, V160 in V052 ne bi prišlo do vplivov NaCl na učinkovitost obdelave odpadne komunalne vode v realnem ETS pri koncentraciji NaCl do 1,0 g/L v 1 vegetacijski dobi. Predvidevamo, da bi se lahko rezultati v realnih ETS razlikovali od naših, saj nismo uporabili odpadne komunalne vode, ki bi lahko povečala privzem vode in pospešila kopičenje NaCl. Poleg tega bi bilo smiselno spremljati odziv vrb in medsebojno delovanje različnih dejavnikov na rast vrb več vegetacijskih dob. Introduction: Evapotranspiration systems (ETS) are among the cleaning plants for treatment and disposal of municipal wastewater, where all wastewater is used to grow plants such as willows. In the ETS, the concentration of salt (NaCl) eventually increases, which has an impact on the efficiency of wastewater treatment and the growth of willow trees. Purpose: With the help of pot experiment, we wanted to determine the impact of different concentrations of NaCl on growth and evapotranspiration of willows in the ETS and compare responses of salinity of 3 different clones of willow trees. Working methods: The pot experiment took place in the greenhouse on 3 clones of White Willow (Salix alba) in the 5 test portions and control batch without NaCl (a total of 90 samples). We tested the following concentrations of NaCl: 0.1 g/L Uvod: Evapotranspiracijski sistemi (ETS) sodijo med čistilne naprave za obdelavo in odstranjevanje komunalnih odpadnih voda, kjer se vsa odpadna voda porabi za rast rastlin, kot so vrbe. V ETS se sčasoma povečajo koncentracije soli (NaCl), kar vpliva na učinkovitost obdelave odpadne vode in rast vrb. Namen: S pomočjo lončnega poskusa smo želeli ugotoviti vpliv različnih koncentracij NaCl na rast in evapotranspiracijo vrb v ETS in primerjati odzive na slanost 3 različnih klonov vrb. Metode dela: Lončni poskus je potekal v rastlinjaku na 3 klonih bele vrbe (Salix alba) v 5 paralelkah in kontrolno serijo brez NaCl (skupaj 90 vzorcev). Testirali smo naslednje koncentracije NaCl: 0,1 g/L 0,2 g/L 0.2 g/L

terasni bloki v Kosezah, atrijski bloki na Viču in stolpnice ob Streliški cesti. Pri vsakem posameznem modelu zazidave je bil opazovan objekt, ki je glede na sončne dobitke lociran najbolj neugodno. S programom Rhinoceros 3D sem izdelala modele pozidave, na katerih je bila nato izpeljana parametrična študija tistega faktorja, ki ima največji vpliv na prejeto sončno sevanje. Prvi parameter, ki je bil opazovan je bila razdalja, kjer sem povečevala ali zmanjševala razmake med objekti, drugi parameter opazovanja je bila rotacija, kjer sem objekte sukala od 0 do 30° v smeri od juga proti zahodu, naslednji parameter je bil razpon notranjega dela atrija, s čimer sem spreminjala velikost notranjega dvorišča. Zadnji parameter obravnave je bila višina, kjer sem spreminjala višino sosednjih objektov. Izvedeni sta bili dve vrsti analize the first was done with the software tools Grasshopper and Diva, where I calculated the average annual solar radiation received by the treated object, and the other included the calculation of the energy required for heating the object in the UMI software tool. The analysis showed that when designing energy efficient buildings, the appropriate density should be taken into consideration, where the solar potential depends on the distance between the objects, the floor area ratio and the consequent mutual shading of objects, as well as the orientation where is the most important the maximized exposure of surfaces to sunlight and its associated shape and object geometry. prva je potekala s programskima orodjema Grasshopper in Diva, kjer sem izračunala, kolikšno je povprečno letno prejeto sončno sevanje obravnavanega objekta, druga pa je obsegala izračun energije, potrebne za ogrevanje objekta v programskem orodju UMI. Analiza je pokazala, da moramo pri načrtovanju energijsko učinkovitih stavb upoštevati primerno gostoto pozidave, kjer je sončni potencial odvisen od razmaka med objekti, faktorja zazidljivosti in posledičnega medsebojnega senčenja objektov, ter tudi orientacijo, kjer je najbolj pomembna čim večja izpostavljenost površin sončnemu sevanju ter z njo povezano obliko in geometrijo objekta. terraced blocks in Koseze, atrium blocks on Vič and skyscraper along Streliška cesta street. For each individual model the building, which is the most unfavorable in terms of solar gains was selected. With the Rhinoceros 3D program, I created the urban patterns models, where a parametric study of the factor which has the greatest influence on the received solar radiation was performed. The first parameter that was observed was the distance between the buildings, where I increased or reduced the spacing between the objects the second parameter of the observation was the rotation, where the objects were rotated from 0 to 30 ° in the direction from south to west. The next parameter was the range of the inward part of the atrium, which changed the size of the inner courtyard. The last parameter of the discussion was the building height where I changed the level of the adjacent objects. Two types of analysis were performed This graduation theses includes a study of the parameters that influence the energy efficiency of the settlement. Influence of factors, that utilization of solar potential depends upon, was observed. According to the discussed apartment building typology, three different, existing urban patterns in Ljubljana were selected Diplomsko delo zajema študijo parametrov, ki vplivajo na energijsko učinkovitost naselja. Opazovan je bil vpliv dejavnikov, od katerih je odvisna izraba sončnega potenciala. Glede na obravnavano večstanovanjsko tipologijo so bili izbrani trije različni, obstoječi vzorci pozidave v Ljubljani

Energy efficiency is an area that is becoming more and more actual. To achieve energy efficiency, different approaches are required. These approaches must be based on ISO 50001 standard and directives of the European Union to assure quality. With the implementation of effective approaches, we reduce energy consumption, costs and extend the lifespan of heating systems, ventilation and air conditioning. Moreover, the comfort of the occupants is improved. The aim of the master thesis is to show the processes by which any building manager optimizes the use of energy with minimal investment. At the Faculty of electrical engineering, we have analysed the condition of the building and its systems of heating, ventilation and air conditioning. For the purpose of analysis, we thoroughly reviewed the state of electrical installations. Where necessary, we created new labels for mentioned installations. For the analysis, we created a tree structure and redesigned building layouts which contained electrical cabinets. With help of this analysis, we have developed procedures that can be performed at the faculty and are suitable for other similar public and private buildings. Soft measures are processes that users can implement themselves and contribute to lower energy consumption. We wrote what are the possible measures to regulate the heating station and what measures for the rooms. We wrote measures that would contribute to the improvement of air quality and a more optimal temperatures in the rooms without an excessive use of heating through the heating station. To determine the energy consumption costs of the faculty, Information system and Energy accounting system were established. A draft of Quality manual was made, which defines duties and persons who must perform these duties. Users often do not know what the procedures for the reduction of energy consumption are. That is why information courses are needed for employees, so that they get enough information to perform these procedures Energetska učinkovitost je področje, ki je vedno bolj aktualno. Za dosego energetske učinkovitosti so potrebni različni pristopi, ki se za zagotovitev kakovosti opirajo na standard ISO 50001 in direktive Evropske unije. Z izvajanjem pristopov učinkovito zmanjšamo rabo energije, stroške in podaljšamo življenjsko dobo sistemov ogrevanja, prezračevanja in klimatizacije. Poleg tega se izboljša tudi udobje uporabnikov prostorov. Cilj magistrskega dela je prikaz postopkov, s katerimi lahko vsak upravljalec stavbe optimizira rabo energije z minimalnimi investicijskimi vložki. Na Fakulteti za elektrotehniko smo analizirali stanje stavbe in njenih sistemov ogrevanja, prezračevanja in klimatizacije. Za namen analize smo najprej temeljito pregledali stanje električnih inštalacij. Kjer je bilo potrebno, smo izdelali nove oznake omenjenih inštalacij. Za analizo smo izdelali drevesno strukturo in prenovili tlorise lokacij električnih omar. S pomočjo analize smo izdelali postopke, ki se lahko izvedejo na fakulteti, primerni pa so tudi za druge podobne javne in zasebne stavbe. Mehki ukrepi so postopki, ki jih uporabniki lahko izvedejo sami in s tem pripomorejo k nižji rabi energije. Zapisali smo, kateri so možni ukrepi na regulaciji toplotne postaje in kateri v prostorih. Za prezračevanje in klimatizacijo smo zapisali ukrepe, ki bi pripomogli k izboljšanju kakovosti zraka in bolj optimalni temperaturi v prostoru, ne da bi s tem obremenili ogrevanje preko toplotne postaje. Za ugotavljanje stroškov na fakulteti je bil vzpostavljen informacijski sistem in energetsko knjigovodstvo. Izdelan je bil tudi osnutek poslovnika kakovosti, v katerem so zapisane dolžnosti in osebe, ki morajo te dolžnosti izvajati. Uporabniki sami velikokrat ne vedo, kakšni so postopki za znižanje rabe energije. Zato so potrebna izobraževanja za zaposlene, preko katerih dobijo dovolj informacij, da lahko izvajajo postopke.

The purpose of this diploma thesis is the energy balance calculation of an apartment building in Logatec, at the address Sončni log 1 and 1a. This data represents the energy efficiency or inefficiency of the apartment building and can be used to introduce renovation possibilities, with which the criteria of an energy efficient building, according to the Regulations on Energy Efficiency in Buildings (PURES 2010, Ur. l. RS, nr. 52/2010: 7840), can be met. . The calculations were carried out using the KI Energija software that is based on the methodology of the Regulations PURES 2010 and the directive Tehnična smernica - učinkovita raba energije (TSG nr. 1-004, 2010). Also carried out was a comparison of the actual U-factors with those in effect at the time of construction planning, because of the inadequate values of thermal transmittance factors of constructional complexes. The KI Energija computer software recorded energy balance calculations which indicate energy efficiency. The chosen building’s energy balance does not meet the criteria of PURES 2010, because the legislation in effect at the time of construction planning, in 2005, involved criteria that were less strict. The most substantial deviations occur in the split-level constructional complex, which divides the heated zone and the garage, because it is not thermally insulated and the U-factor exceeds the threshold by 1,1 W/(m2K). The most energy-efficient renovation measures include additional thermal insulation of split-level constructional complexes and the non-permeable exterior, while also installing a mechanical ventilation system with heat recovery. Namen diplomske naloge je izračun energetske bilance za večstanovanjsko stavbo v Logatcu, na naslovu: Sončni log 1 in 1a, v okviru katere želimo prikazati energijsko ustreznost oziroma neustreznost večstanovanjske stavbe in podati predloge sanacije, s katerimi lahko dosežemo kriterij energetsko učinkovite stavbe po Pravilniku o učinkoviti rabi energije v stavbah (PURES 2010, Ur. l. RS, št. 52/2010: 7840). Izračun je izveden s programom KI Energija, ki temelji na metodologiji po PURES-u 2010 in Tehnični smernici - učinkovita raba energije (TSG št. 1-004, leto 2010). Zaradi neustreznih vrednosti faktorjev toplotne prehodnosti konstrukcijskih sklopov je narejena primerjava med dejanskimi U faktorji in faktorji, ki so bili veljavni v času projektiranja. S pomočjo računalniškega programa KI Energije je izpisana tudi računska energetska izkaznica, ki je pokazatelj energetske učinkovitosti. Energetska bilanca izbrane stavbe ne ustreza kriterijem PURES 2010, saj je bila v času projektiranja leta 2005 veljavna zakonodaja z manj strožjimi kriteriji. Največja odstopanja so pri medetažnem konstrukcijskem sklopu, ki ločuje ogrevano cono in garažo, ker ni toplotno izoliran in U faktor presega mejne vrednosti za 1,1 W/(m2K). Energetsko najučinkovitejši sanacijski ukrepi so dodatna toplotna izolacija medetažnih konstrukcijskih sklopov in netransparentnih zunanjih površin ter vgradnja mehanskega prezračevanja z rekuperacijo toplote.

The Sun is one of the biggest alternative sources of energy that can be exploited for heating water and living or work areas with the help of the solar collector. The use of the solar collector can be presented to the pupils in primary school in a very illustrative way. A model of the solar collector can help pupils to learn about the energy flow when water is heated using the solar collector. The purpose of my thesis is to present one of many ways how to interconnect many physical phenomena in one specific example and how to learn something from it. I have used the measurements of energy flow which I had carried out on the model of the solar collector to calculate how much energy is used to heat water. I have also investigated where the rest of the energy is diverted, where the losses of energy occur and how the energy in the model of the solar collector flows. Energy conservation is one of the most important concepts in the curriculum for primary schools. All the pupils are expected to acquire knowledge of this field. Therefore, it is very important to present them these concepts in an illustrative and interesting way. Based on the analysis of the measurements I have prepared the material, which could allow pupils to better understand the energy conservation as well as of the functioning of the solar collector. The material is suitable for use in primary schools. I have prepared additional material for the students of the Faculty of Education. The material is intended to be used during a science day. Sonce je eden izmed največjih alternativnih virov energije, ki ga lahko s pomočjo sončnih kolektorjev zelo dobro izkoriščamo za segrevanje vode in prostorov. Uporabo sončnega kolektorja lahko na zelo nazoren način predstavimo osnovnošolcem. Z uporabo modela sončnega kolektorja učenci spoznajo energijske procese, ki potekajo pri segrevanju vode s sončnim kolektorjem. Predstaviti želim enega izmed mnogih načinov, kako lahko na konkretnem primeru povežemo več fizikalnih pojavov in se iz njih tudi kaj koristnega naučimo. Z meritvami energijskih procesov, ki sem jih na modelu sončnega kolektorja opravila, sem izračunala del energije, ki se porabi za segrevanje vode. Raziskala sem, kam se preostali del energije preusmeri, kje nastajajo izgube in kako pri modelu sončnega kolektorja potekajo energijski procesi. V učnem načrtu za osnovno šolo je ohranitev energije eden izmed pomembnejših konceptov, ki naj bi jih učenci osvojili na vseh nivojih, zato je pomembno, da učencem takšne koncepte približamo na nazoren in njim zanimivejši način. Na podlagi analize meritev sem pripravila gradivo, ki bi učencem omogočalo kakovostnejše razumevanje ohranitve energije kot tudi samega delovanja sončnega kolektorja. Uporaba gradiva je predvidena za izvedbo naravoslovnega dne v osnovni šoli. Posebej sem pripravila še dodatno gradivo za študente Pedagoške fakultete.

The research presented in this thesis is concerned with the accessibility of information on the world web, crucial for the decision making process regarding products and services required for building refurbishment. This information is often dispersed, poorly structured and written in various formats. As a consequence, information search on the web can be extremely time-consuming and difficult to carry out. The information can be sequenced in a workflow consisting of a series of interconnected services which are executed in orchestrated steps. The research hypothesis postulates that the workflow information system model is able to encompass a large proportion of key information and knowledge from the sustainable construction field. As such, it represents efficient information support to potential clients and construction contracting companies. Information support requirements of various stakeholders from the construction sector were identified by using a survey. The obtained results exhibit a clear need for structured information, as well as a significant willingness of stakeholders to share the information. An overview of the existing solutions and accomplishments in sustainable construction is presented. The concept of sustainability assessment is presented, along with an overview of the most frequently employed approaches for the sustainability assessment of buildings, which reveals differences in assigning relative importance to individual sustainability aspects. An overview of the Slovenian residential building fund is carried out. It shows that the majority of residential building stock is in need of refurbishment. Further, semantic technologies that enable the establishment of advanced information systems are presented. The second part presents the development of a workflow-based prototype information system. The design of the information system architecture is presented, together with the decision making model and the ontology that supports information recording into workflows and data storage into the OWL/RDF database. The validation of the information system is presented in the concluding part. It is shown that the system requirements defined in the beginning of the research were achieved Doktorska disertacija obravnava področje dostopnosti informacij, pomembnih za odločanje o izbiri storitev in proizvodov pri prenovi stavbe. Te so pogosto neurejene in razpršene po celotnem spletu ter zapisane v različnih formatih. Posledično je lahko iskanje želenih informacij zelo zamudno in nepregledno. Informacije lahko zajamemo v delotoku, ki predstavlja zaporedje povezanih storitev, izvajanih v primerno orkestriranih korakih. Osnovna hipoteza trdi, da lahko model informacijskega sistema delotokov zajame visoko stopnjo ključnih informacij in znanj na področju trajnostne gradnje in načrtovanja ter kot tak predstavlja primerno informacijsko podporo gradbenim podjetjem in investitorjem. Potrebe po informacijski podpori ugotavljamo s pomočjo raziskave med ključnimi deležniki na področju gradbeništva. Rezultati izvedene raziskave razkrivajo velike potrebe po dostopu do urejenih informacij in kažejo na veliko pripravljenosti deležnikov za sodelovanje ter medsebojno deljenje informacij. Izdelan je pregled obstoječih rešitev in dognanj na omenjenem področju. Predstavljen je trajnosten pogled na stavbe s pregledom najbolj razširjenih in aktualnih pristopov trajnostnega ocenjevanja stavb, ki razkriva razlike pri pripisovanju teže posameznim trajnostnim vidikom. V nadaljevanju izdelamo pregled stanja slovenskega stavbnega fonda, ki razkriva, da je velika večina stavb potencialno potrebnih prenove. Predstavljene so tudi semantične tehnologije, ki omogočajo izdelavo naprednih informacijskih sistemov in ki jih zato uporabimo v nadaljnjem delu. V nadaljevanju dela je predstavljen razvoj prototipa informacijskega sistema, ki temelji na delotokih. Opisana je zasnova arhitekture informacijskega sistema, model sprejemanja odločitev in razvita ontologija, ki podpira zapis informacij v delotoke in hrambo informacij v pripadajoči podatkovni bazi OWL/RDF. V zaključnem delu je predstavljena validacija prototipa informacijskega sistema, ki kaže, da smo uspeli zadostiti opredeljenim zahtevam. Postavljena hipoteza je torej potrjena. the initial hypothesis is therefore confirmed.

V diplomski nalogi je predstavljena izdelava računskih energetskih izkaznic za izbrana stanovanjska objekta. Povečanje obsega energijske prenove starejših stavb je ena izmed glavnih pobud za doseganje ciljev evropske energijsko okoljske politike. Obstoječe stanje stavbnega fonda v Sloveniji zahteva velike potrebe po energiji. S spodbujanjem energetske učinkovitosti in uporabo obnovljivih virov energije v stavbah bi lahko potrebo po energiji znatno zmanjšali. V diplomskem delu sem opisala evropsko in slovensko zakonodajo na področju energetske učinkovitosti stavb. Osredotočila sem se na opis metodologije izdelave in izdaje energetskih izkaznic. Pri izdelavi energetskih izkaznic sem upoštevala zahteve aktualnega Pravilnika o učinkoviti rabi energije v stavbah (2010). Računske energetske izkaznice sem izdelala za dve stanovanjski stavbi one is a family house in Horjul and the other is an apartment building in Ljubljana. I described the location and technical properties of both buildings. Hardware TOST was used for calculating energy efficiency properties of the buildings. First I analyzed existing condition of the buildings then I chose some cost efficient measures. I compared the results with existing condition and chose the most efficient ones for renovation. After selecting cost efficient measures I created the final energy performance certificates. The first two certificates describe the existing condition of buildings. The other two energy performance certificates present the simulation of reduced energy efficiency indicators after implantation of chosen cost efficient measures. enostanovanjsko hišo v Horjulu in večstanovanjski blok v Ljubljani. Opisala sem lokacijo in tehnične lastnosti posameznih stavb. Za izračun kazalnikov energijske učinkovitosti stavb sem uporabila računalniški program TOST. Najprej sem naredila analizo obstoječega stanja nato sem predlagala in preverila učinkovitost posameznih možnih ukrepov. Za vsako stavbo posebej sem primerjala rezultate z obstoječim stanjem stavb. Na podlagi rezultatov sem izbrala kombinacijo stroškovno učinkovitih ukrepov, za katere sem tudi izdelala končno energetsko izkaznico. Končni rezultat predstavljajo štiri izdelane računske energetske izkaznice. Prvi dve opisujeta obstoječe stanje stavb, v drugih dveh energetskih izkaznicah pa je prikazana simulacija prenove. The thesis presents calculated energy performance certificate of two selected residential buildings. The targets of European climate and energy policies for reduction of consumed energy include energy efficiency of buildings. Current buildings fund in Slovenia demands great need for energy. Great reduction of energy demands and its’ more efficient use can be achieved by use of renewable energy sources in buildings. In the thesis I have described European and Slovenian legislation regarding energy efficiency in buildings. The focus lies in the methodology for making energy performance certificate. It must meet the demands of current Slovenian legislation. I did the energy performance certificate for two selected buildings
