Potential heat savings during ongoing renovation of buildings until 2050

Research output: Book/ReportReportCommissioned


This report presents analyses with the purpose to clarify the energy savings of net heating until 2050 if the building components are being upgraded according to the requirements stipulated in the Danish Building Regulation 2010. Upgrading is assumed to be introduced when the building components need renovation anyway due to the building materials used having reached the end of their service life. The analyses are compared with an evaluation of the effect of a 100 % compliance with the requirements as this constitutes the ultimative energy savings in combination with planned building renovation. Additionally, the effect of implementing more tight energy requirements has been analysed.
A calculation model has been established using information from the Danish building and dwelling stock register (BBR) and data from the Danish building energy certification (EPC) scheme that include information about insulation level, building component areas, i.e. roofs, external walls, floors and windows/doors, per unit area (gross heated floor area).

The report is made for the Danish Energy Agency and targeted the Danish building industry, the agency itself and political decision makers in preparation for the Danish 2014 strategy for energy renovation of buildings.
