The building sector has enormous impacts on our environment and the influence of building performance on broader sustainability is widely acknowledged. About 40% of the overall energy consumption in Europe is related to the building sector and represents about 1/3 of Europe’s CO2 emissions. More than 50% of all materials extracted from earth and 25% of all virgin wood are transformed into construction materials and products. If the building sector is to significantly contribute to the 90% GHG reduction target for 2050, each building, on average, will have to demonstrate very low carbon emission levels and consume very low energy in the context of a decarbonised power sector. For most of Europe’s buildings, this probably means improving the current average energy consumption by a factor four or five and the installation of renewables. For some it could even mean improvement by a factor 10. In order to achieve those improvements deep renovation scenarios are needed.
In response to the above mentioned challenges BERTIM will provide:
