Actual heating energy savings in thermally renovated Dutch dwellings

Since previous research has indicated large discrepancies between the theoretical and actual heating consumption in dwellings, it is important to know what savings renovations achieve in reality. The register of the Dutch social housing stock was analysed, containing dwelling thermal performance information of ca. 2 million dwellings between 2010 and 2013. Renovated dwellings were identified, providing insight into the performance gap before and after the renovation and the actual vs. the theoretical energy reduction of renovation measures. Improvements in efficiency of gas boilers (space heat... Mehr ...
