Decarbonization of Cities and Communities (Cities TCP)

The Cities TCP is a joint international effort that aims to accelerate the decarbonization in cities by providing a communication platform for relevant expertise of all IEA bodies to the local scale including cities, financing institutions, utilities, service providers and building constructors. Vice-versa, the platform generates evidence-based research questions of cities needs for IEA TCPs.

IEA Hybrid and Electric Vehicles (HEV) Task 40: Critical Raw Materials for Electric Vehicles

The production of electric vehicles and batteries requires critical raw materials. In Task 40, demand and supply are compared, based on global scenarios of the development of electric vehicle fleets, battery technologies, primary and secondary raw material potentials and recycling technologies. Potential overall ecological and social impacts of raw material and battery production are assessed. Schriftenreihe 3/2024

IEA EBC Annex 73: Towards Net Zero Energy Resilient Public Communities

Public buildings such as hospitals and educational institutions often house critical infrastructure that depends on sufficient energy and resource supply. The aim of the annex was to develop tools for the planning process of resilient, efficient and low-emission energy systems for such building clusters.

IEA EBC Annex 61 - Business and Technical Concepts for Deep Energy Retrofit of Public Buildings

Target of IEA EBC Annex 61 was the development of technical and economical concepts for Deep Energy Retrofit of public buildings. To force high-quality and energy efficient retrofit, besides the enhancement and dissemination of innovative, technical retrofit concepts, the focus was in the development of innovative business models (energy-contracting).

IEA EBC Annex 67: Energy Flexible Buildings (working period 2015 - 2019)

The project increased the knowledge on building Energy Flexibility and the regarding potential buildings can provide to energy grids. The critical aspects and possible solutions to utilize the Energy Flexibility that buildings can provide were identified and a report of the “Principles of Energy Flexible Buildings” will be published in 2019.

Process Heat Collectors State of the Art within Task 33/IV (Weiss/Rommel 2008)

Approximately 128 GWth, the equivalent of 183 million square meters, of solar thermal collectorswere installed by the year 2006 worldwide (Weiss et al., 2008). Until now, the widespread use of solarthermal applications has focused almost exclusively on swimming pools and residential domestichot water preparation and space heating. Englisch

IEA EBC Annex 63: Implementation of Energy Strategies in Communities

As part of the "Annex 63" project, Austria has worked with 10 other countries to develop guidelines for the successful implementation of energy strategies at local level. The results include support for nine strategic measures, descriptions of case studies, support materials and recommendations for different target groups.

IEA HEV TCP Task 49: Electric Vehicle-Fire Safety

As the number of electric vehicles increases, so does the need for safety. The project is creating an overview of fire safety standards for electric vehicles and networking relevant stakeholders. Challenges are discussed and experiences exchanged in national and international expert workshops. The focus is on promoting the safety of electric vehicles and increasing their acceptance.

Solar Heat Worldwide - Markets and Contribution to the Energy Supply 2005

The solar thermal collector capacity in operation worldwide equaled 107.8 GWth corresponding to 154 million square meters at the end of the year 2005. Of this, 90.7 GWth were accounted for by flat-plate and evacuated tube collectors and 16.2 GWth for unglazed plastic collectors. Air collector capacity was installed to an extent of 0.9 GWth.

# EEG+ digital energy communities

The project addressed issues related to plus-energy neighborhoods and energy communities, both of which aim to make buildings more sustainable. The aim was to explore synergy effects and to research a possible implementation as a demonstration.

EdeN - Efficient decentralized sustainable food production

In the EdeN project, a decentralized vertical farming concept is extended to meet circular economy requirements. The combination of vertical farming with closed energy-, resource- and distribution-loops is a possible disruptive concept in food production. The developed concepts will be accessible and transferable to other food producers, and its limitations will be pointed out.

DigiTech4CE - Digital key technologies for circular production

DigitTech4CE analysed industrial cycles in discrete, digitalised production; their participants, advantages/disadvantages and framework conditions, as well as the key digital technologies required. Fields of action were developed, according to the needs of Austrian industry. Recommendations for action serve the development of sustainable, Austrian production that builds and expands competitiveness through circular innovations.

AGreeNew - New biobased products of the agricultural biorefinery

AGreeNew aims to expand the product portfolio of the agricultural biorefinery. Sour whey, farm manure and green silage will be used as raw materials to produce biosurfactants, fertilizers and protein-rich animal feed. The production processes of these valuable products will be assessed in terms of sustainability and economic potential.

Vertical Farm Aspern - Democratization of vertical farming under consideration of parameters of circular economy

Planning, construction and optimization of a vertical farm for urban food production, involving the users in the operational management. The building and the operator concept represent the entire food value chain, from planting to selling.

IEA EBC Working Group on Cities and Communities (WGCC)

The WGCC enables information and experience exchange, the identification of bottlenecks that lead to specific research questions and a direct communication with cities on their needs, to enable them to transform their energy systems. The working group is a joint initiative across several TCPs with in-depth participation of technical and non-technical (external) experts.

Webinar: Future weather data and heatwaves

31. May 2022
Online, AT

Well-insulated and air-tight buildings are known to be vulnerable to overheating. An increase in the severity and duration of heatwaves is expected, resulting in more severe overheating risks, affecting on their turn the health and mortality of building users. To achieve more future-proof buildings, it is crucial to design buildings that are "resilient" to overheating in future climate conditions.
