Four Positive Energy Building (PEB) demo sites lie at the heart of EXCESS to test cost-competitive building technology packages in four EU climatic zones: Graz, Austria The PEB will have multifunctional facade elements with integrated PVs and elements for load shifting, storage, user integration and interaction with the local electricity grid. Hasselt, Belgium A district heating network sourced by geothermal heat pumps, PVT panels and a small windturbine will provide renewable electricity, heating and domestic hot water. Granada, Spain The planned PEB will optimise energy generation via photovoltaic applications, a geothermal system, an integrated control system and prioritise self-consumption of renewable energy and include natural ventilation systems. Helsinki, Finland The PEB will have a hybrid geothermal energy system combining semi-deep geothermal energy wells with coaxial collectors in ~800 meter deep boreholes, heat pumps, PV panels, solar thermal PVT for electricity and heat.
Overall, the EXCESS project is guided by a S.M.A.R.T. approach (Specific, Measurable, Achievable, Relevant and Time-Oriented) to reach its ambitious objectives. In so doing the project consortium will deliver measurable impacts, including (1) the advancement of new materials, technologies and integrated technological systems; (2) the optimisation of the interplay of local energy generation, storage, consumption at building and district-level; (3) the promotion of a user-centric approach as well as (4) the effective dissemination, communication, replication and exploitation of activities and improved market uptake.
