FleXible user-CEntric Energy poSitive houseS

Project description

Building energy-saving solutions for harsh climates

Reducing energy consumption in multi-storey buildings is important for meeting the EU energy efficiency targets. Positive energy buildings (PEBs) generate more energy than they consume. The role of renewable energy systems (RES) and smart technologies is rather limited in harsh climates. More effective energy materials as well as upgraded single technologies are needed for construction to achieve user-centred flexible selling policies. The EU-funded EXCESS project will develop new low-cost PEB solutions for the European housing market. It will improve materials, technologies and integrated technological systems. The project will prepare the solution for the market and test it in four EU countries.


The EXCESS project builds up on nearly-zero energy multi-storey building (consumption below primary energy threshold) residential concepts of the main 4 EU climatic zones towards Energy fleXible user-CEntric poSitive houseS (EXCESS). EXCESS defines a positive energy building (PEB) as a building that produces more energy than they use, with high RES self- consumption rate (instead of using the grid for solving seasonal balancing issues) over a time span of one year. RES and smart technologies exist, but complete packages for different climates do not.
Important technical developments for plus energy building materials and other individual technologies are required to address specific climate related needs in order to meet the PEB level; especially in harsh climates. Integration is needed for upgrading single technologies to be part of a large orchestra enabling also user-context-aware energy flexible services between utilities and customers (selling flexibility). These will unlock additional revenue streams that reduce the lifetime cost of the developed PEB solutions, making them affordable also large portion of the society. Thus, EXCESS will advance new materials, technologies and integrated technological systems (TRL5-7) promoting a user centric approach (building tenants), capitalized on new ICT opportunities, for optimizing the interplay of local generation, storage, consumption at the building and district level. The demonstration activities in each of the climatic zones (Austria, Belgium, Finland and Spain) will be accompanied by co-innovation, replication and exploitation activities to maximize the project technical, social and economic impact and to prepare for a future market roll out of the PEB concept by also scouting energy efficiency funding opportunities.
