BRICKER Project: Power, Heating and Cooling for Non-Residential Buildings Feeding with RES
Abstract
Existing non-residential buildings represent a valuable asset in Europe. These buildings account for 25% of the total building stock in Europe and comprise a more complex and heterogeneous sector compared to the residential one. The public non-residential building stock represents an average 31% of the total non-residential sector in Europe. Understanding the energy use and CO2 emissions in the non-residential sector is complex as end-uses such as lighting, ventilation, heating, cooling, refrigeration, IT equipment and appliances vary greatly from one building category to another within this sector. The average specific energy consumption in the non-residential EU27 sector is 280kWh/m2 (covering all end-uses). A retrofitting solution package for existing public-owned non-residential buildings is needed in order to achieve a drastic reduction of the energy consumption (beyond 50%) and GHG emissions in this sector. This retrofitting package is based on; Envelope retrofitting solutions for demand reduction through made-to-measure façades, innovative insulation materials and high performance windows and zero emissions energy production technologies based on a cogeneration system fed with locally available and clean renewable sources. The retrofitting solution package is implemented in three real demonstration multi-buildings complexes, located in different climate conditions in three different European Countries and with different end-uses: Sanitary, Educational and Administrative.
