Periodic Reporting for period 1 - RES4BUILD (Renewables for clean energy buildings in a future power system)
Reporting period: 2019-05-01 to 2020-10-31
Decarbonising energy consumption in buildings is a priority in order to meet EU targets for a clean and efficient energy future. While the use of renewable electricity in buildings has progressed, the uptake of renewable energy heating/cooling solutions in the built environment has been slower. Their larger energy share within buildings, together with the many technological options available and the diverse types of buildings and requirements of the end users makes it difficult to find a standard solution.
RES4BUILD will address these challenges by developing integrated cost-competitive renewable-energy-based solutions that are tailored to the needs and requirements of the users and the installers. The project will:
• Improve the performance and reduce the cost of the most innovative components of the RES4BUILD solutions.
• Develop tools for simulation, sizing and control; making optimal use of the IES and the flexibility of consumption, while respecting the wishes of the end-users.
• Engage all relevant stakeholders in co-designing IES that suit current needs and future expectations.
• Test and validate various RES4BUILD solutions in different climates to pave the way for bringing the developed solution to the market, ensuring wide adoption.
Innovative combinations of promising and established technologies designed together with the main stakeholders will deliver IES to decarbonise the energy used in the main building types in Europe. RES4BUILD prioritizes the space heating, space cooling and hot water needs of buildings, while managing the electricity generation and the buildings energy demand, ensuring that the interaction with the grid is minimised. The co-design process will assist towards obtaining consensus of an integrated package of energy measures fit-for-purpose – resulting in clean, more efficient and affordable energy options for consumers in buildings across Europe.
Besides establishing strong interdisciplinary, intersectoral and international collaborations, the participation of industrial organisations will help advance the implementation of innovative scientific ideas. New knowledge generated outputs will be relevant beyond the application of the project, with opportunities for adapting them to develop products and/or services in any aspect of the building sector and potentially other industries.
The integrated solution is intended to be implemented on a building-scale that has the potential to supply all a building’s heating, cooling and electricity needs, allowing for implementation without excessive requirements. The flexible approach allows for solutions to be applicable to a wide variety of buildings, new or renovated, tailored to their size, type and the climatic zones of their location. The final RES4BUILD Integrated Energy Systems (IES) will cover an estimated 80 - 100% of the energy needs for new multi-family buildings across Europe - leading to more efficient operation and optimised interaction with the grid, and thus a lower energy bill for European consumers. The integrated approach is expected to be cost competitive compared to traditional solutions by 2025, considering the effect of economies of scale.
The co-design process will help improve understanding of the best process to approach renovations of energy systems in a more integrated and systematic way. This approach of RES4BUILD will address the complex social priorities and needs in order to accelerate the energy transition. The project will lead to buildings which provide higher comfort levels and wellbeing for their occupants. Well-heated and ventilated buildings reduce negative health impacts caused by dampness. In addition, the increased construction activities in the form of renovation will lead to job creation and increase economic growth in the EU.
