Abstract
A study has been conducted analysing the energy savings for space heating and domestic hot water in the Danish building stock due to renovation of building components at the end of their service life. The purpose of the study was to estimate the energy savings until 2050 as building components are energy upgraded according to the requirements stipulated in the Danish Building Regulations 2010. Furthermore, scenario analyses was made for the potential impact on the energy consumption of introducing different levels of tightening of the energy requirements for existing buildings in the Danish Building Regulations.
Compliance with the requirements in the Danish Building Regulations will potentially result in energy savings for space heating and domestic hot water around 30 % until 2050. Further tightening of the component insulation level requirements will only result in marginally higher savings, due to the level of the current requirements. Higher energy savings can, though, be achieved
e.g. by setting requirements for balanced mechanical ventilation with heat recovery and use of solar heating for domestic hot water.
