Buildings retrofitting potential in the EU is huge and existing heating/cooling technologies do not sufficiently enable the integration of new advanced efficient systems. Proposals should embrace two types of buildings: residential buildings and district heating/ cooling connected buildings. For both types, the integration of new reliable systems should be based on new or existing reliable design tools which would facilitate taking the decision on the installation of the best solutions. The research activities should at least address the following areas:
Concerning the district systems, advanced District Heat and Cooling (DHC) systems, i.e. systems operating at low temperatures, must be able to deal with both centralised and de-centralised hybrid sources (e.g. solar thermal, biomass, geothermal, heat pumps, waste heat, excess renewable electricity storage).
Proposals should provide detailed information on the energy data of the buildings (current energy use and proposed reduction with new equipment, the gross floor area of the building together with the targeted annual energy use per m2, broken down by space heating, cooling, domestic hot water production, and lighting). The energy use should achieve at least the national limit values for new buildings according to the applicable legislation based on the Energy Performance of Buildings Directive.
Activities are expected to focus on Technology Readiness Levels 5 to 7 and to be centred around TRL 6.
A significant participation of SMEs with R&D capacities is encouraged.
The Commission considers that proposal requesting a contribution from the EU between EUR 5 and 7 million would allow this specific challenge to be addressed appropriately. Nonetheless, this does not preclude submission and selection of proposals requesting other amounts.Expected Impact:
Proposals should include a business case and exploitation strategy, as outlined in the Introduction to the LEIT part of this Work Programme.
