IEA ES Task 44: Power-to-Heat and Heat integrated Carnot Batteries for Zero-Carbon (industrial) heat and Power supply
The rise of renewable energy causes fluctuating energy production. The electrification of heat supply further challenges the electricity grid. Coupling electricity and heating with thermal storage helps to strengthen grid resilience and ensures stable energy supply. This project identifies and evaluates heat-integrated Carnot battery concepts to store thermal and electrical energy and supply electricity and thermal energy on demand.

EASEY Venture Capital Transfer
Sensitizing and capacity building for networking of venture capital and developers of sustainability technologies was performed to develop options for establishing a financing platform which regards sustainability requirements.
IEA ES Annex 50: Prefab Systems for Low Energy/High Comfort Building Renewal
Development of integrated concepts for multi-storey buildings, which enable renovations of buildings with high energy efficiency at good user acceptance during the realisation phase as well as afterwards (comfort, affordability). Relevant components: integrated solutions of roof and façade with high rate of pre-fabrication, the possibility of integrating the energy façade/roofs and energy distribution and supply.
IEA ES Annex 49: Low Exergy Systems for High-Performance Buildings and Communities
The objective of Annex 49 is the development of approaches for reducing the exergy demand of buildings, so as to reduce the CO2 emissions of the building stock and support structures for sustainable and reliable energy systems in the building sector. To achieve the objectives of Annex 49, the following activities have been carried out:Application of exergy analysis and providing tools, guidelines, best-practice examples and background information for planners and decision makers in the fields of construction, energy and politics Support of cost-efficient low-energy/exergy measures for renovation and new building taking into account both the residential and the service sector Promotion of exergy-related performance analysis of buildings, particularly from the perspectives of communities / regions
HY3GEN - A Regenerative Building
The "third generation hybrid building" (HY3GEN), whose main features are being defined in this project, has expanded this approach to include the integration of aspects of efficient resource utilization in construction and operation as well as the use of regenerative raw materials and renewable energy.
IEA ES Task 45: Accelerating the uptake of Large Thermal Energy Storages
The aim of Task 45 is to accelerate the market launch of large-scale heat storage systems. For this purpose, numerical simulation techniques and material measurement techniques are to be improved and a material database expanded. In addition, a standardized evaluation and communication basis will be developed leading to a method for yield assurance. The methods and findings will be disseminated specifically to municipal utilities, planners and operators of district heating systems as well as decision-makers.
IEA EGRD Workshop: Technologies and innovations for the climate-neutral city

User-Centred Energy Systems (UsersTCP)
The UsersTCP provides evidence from socio-technical research on the design, social acceptance and usability of clean energy technologies. Users play a central role within energy systems. The findings will support political decisions for a clean, efficient and safe energy system.
ERSCP 2021 - European Roundtable on Sustainable Consumption and Production
8. - 10. September 2021
Graz
ERSCP21 will consider the possibilities to reduce the emission of climate-relevant gases during production as well as to reduce upstream emissions by changing consumer behavior. The topics discussed at the conference cover a number of UN Sustainable Development Goals.
RCC – Reduced Carbon Concrete: Implementation of CO2-redudes concrete in construction sites
The objectives of the present project "RCC - Reduced Carbon Concrete" were to test the current knowledge about the temperature-dependent curing processes of performance concretes by concrete work on large components on the construction site, under summer and winter conditions, and in precast production. The results will be incorporated into construction practice and standardization work.

IEA EGRD Workshop - Green Fuels
21. - 22. October 2019
IEA headquarters in Paris (FR)
The workshop aimed to address questions about energy carriers of the future, the role of alternative fuels in sector coupling as well as technological challenges, risks and co-benefits.
Wastewater cycle. Cascadic recycling of wastewater and organic residue streams in buildings.
Basic research is being conducted for a sustainable cycle-oriented system for the building-integrated recycling of wastewater and food waste. This includes nutrient recovery for a sustainable circulation system (production of plant fertiliser and biochar), electricity production to meet the demand (up to 15 %) of plus-energy buildings, as well as water recovery for irrigation of the building's own or urban greenery and for summer cooling.
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.
