Examples of concrete compositions are provided, application and tendering aspects are discussed, practical applications are described by means of some historical and recent cases, … and many more. This e-handbook can help you to become actively involved into a more sustainable built environment. This open access e-handbook is the joint effort of the EU-projects URBCON and DuRSAAM.

Coming to an end in April 2020, the ERIGrid project organised its Virtual Final Conference dedicated to presenting the outcomes of the 5 years of work towards the integrated research infrastructure for smart grid systems. The project consortium presented the ERIGrid holistic testing approach for validating cyber-physical energy systems and other outstanding achievements on April 1, 2020. ERIGrid’s free access to Europe’s leading laboratories (Transnational Access) has also been covered, i.e., successful users presented their energy efficient solutions that they tested at the labs of ERIGrid partners. The following presentations have been provided: Session “ERIGrid Achievements“ Welcome and ERIGrid Overview System-level Testing Approach Laboratory Coupling Approach Laboratory and Hardware-in-the-Loop based Assessment Methods Simulation-based Assessment Methods Education and Training Methods and Tools Outlook ERIGrid 2.0 Session “Facilitating Effective Laboratory Testing by Lab Users” Overview of Achievements of the ERIGrid Transnational Access Programme Application of OLTC Transformer and Distributed Generation for Voltage Control on Low Voltage Distribution Networks Datalogging, Power Converters and Machine Learning: How ERIGRID has kick started my research on planned perennity in microgrids Hardware-in-the-Loop Modelling, Simulation and Closed-Loop Testing of a distribution integrated PV Plant VILLAS4ERIGrid: Geographically Distributed Real-time Simulation and PHIL between TU Delft, DTU Risø, Lyngby and RWTH Aachen Extensive Impacts of SunHILL Impact of Time variant Grid Impedance on Power Line Communication System

Solar energy has been actively promoted as a clean energy source since 1973���s oil crisis, evidenced by the emergence of initiatives such as the Solar Heating & Cooling Programme of the International Energy Agency or the US Department of Energy. Nonetheless, solar technologies have not been widely used in the built environment, limiting their operation to industrial and macroscale applications. Commercially available products such as building integrated PV panels (BIPV) or building integrated solar thermal collectors (BIST); and novel prototypes and concepts for solar cooling integrated facades are seen as interesting alternatives for the development of new performance based fa��ade components for high-performing commercial buildings. However, there are barriers to overcome in order to promote widespread application of architecturally integrated solar components. The present paper seeks to discuss perceived barriers for widespread fa��ade integration of solar technologies, in order to define the current scenario and generate guidelines for future developments. In order to achieve this, the paper presents the results of a survey addressed to professionals with practical experience in the development of fa��ade systems for office buildings, situated at any stage of the design and construction process. Hence, architects, fa��ade consultants, system suppliers and fa��ade builders were considered. The outcome of this study is the definition of the main perceived barriers for fa��ade integration of solar technologies, discussing the results from the survey along with other related experiences found in the literature. This study is part of the ongoing PhD research project titled COOLFACADE: Architectural integration of solar cooling strategies into the curtain-wall, developed within the Fa��ade Research Group (FRG) in the Green Building Innovation programme (GBI) of the Faculty of Architecture and the Built Environment, TU Delft.

This report summarises findings on wind integration from the 17 countries orsponsors participating in the International Energy Agency Wind TechnologyCollaboration Programme (IEA Wind TCP) Task 25 from 2006–2020. Both realexperience and studies are reported. Many wind integration studies incorporatesolar energy, and most of the results discussed here are valid for other variablerenewables in addition to wind.The national case studies address several impacts of wind power on electricpower systems. In this report, they are grouped under long-term planning issuesand short-term operational impacts. Long-term planning issues include gridplanning and capacity adequacy. Short-term operational impacts includereliability, stability, reserves, and maximising the value of wind in operationaltimescales (balancing related issues). The first section presents the variability anduncertainty of power system-wide wind power, and the last section presentsrecent studies toward 100% shares of renewables. The appendix provides asummary of ongoing research in the national projects contributing to Task 25 for2021–2024.The design and operation of power and energy systems is an evolving field. Asambitious targets toward net-zero carbon energy systems are announcedglobally, many scenarios are being made regarding how to reach these futuredecarbonized energy systems, most of them involving large amounts of variablerenewables, mainly wind and solar energy. The secure operation of powersystems is increasingly challenging, and the impacts of variable renewables, newelectrification loads together with increased distribution system resources willlead to somewhat different challenges for different systems. Tools and methodsto study future power and energy systems also need to evolve, and both shorttermoperational aspects (such as power system stability) and long-term aspects(such as resource adequacy) will probably see new paradigms of operation anddesign. The experience of operating and planning systems with large amounts ofvariable generation is accumulating, and research to tackle the challenges ofinverter-based, nonsynchronous generation is on the way. Energy transition anddigitalization also bring new flexibility opportunities, both short and long term.

This e-book has been made in the framework of the European Training Network on Durable, Reliable and Sustainable Structures with Alkali-Activated Materials (DuRSAAM), which organized a training course on AAM technology held at Karlsruhe Institute of Technology 27-29 January 2020. This open source book collects the lecture notes by the teachers of this training course and provides building professionals and stakeholders new insights on alkali-activated concrete as an emerging building technology.

The quality of indoor air is linked to detrimental health effects. Indoor air is a research and design issue in healthy housing, rarely considered in sustainable building. By analysing the relation between sustainable building and indoor air, a framework for discussion is constructed. The question is how the relation between healthy indoor air and sustainable building can be improved. The authors conclude that fresh air can be treated as an essential consumption good, which is produced by building services. Fresh air must be “created” in situations when the collected outdoor air needs to be filtered, heated, transported, consumed and replaced. After its use, the air is exhausted as waste material. The energy consumption, pollution process and re-cycling can be accounted for in life cycle assessment calculations. From the perspective of flows, airflows can be added to the flows of materials, energy and water during the entire life cycle of the building. The integration of flows in terms of consumption of fresh air will result in a better balance between strategies on the level of each flow. In this way it will be possible to make a stronger link between healthy indoor air and sustainable building.

The information bundled in this e-book is that of a 4-day course, formatted as a training school open to researchers, practicing engineers, etc., in fact, for all those who want to obtain profound starting knowledge on the structural application of alkali-activated concrete, also in the wider framework of circular concrete solutions.
