this research seeks to provide insight into the energy performance progress, of the existing non-profit housing stock in the netherlands, through the application of energy renovations. the non-profit housing stock comprises 30% of the housing market in the netherlands and a large part of the policies towards a more efficient housing stock rely on the non-profit housing sector. to that end, we determine the energy renovation rate of the stock and the impact of the applied renovations on both the predicted and actual energy consumption. the difference of predicted and actual energy savings is analysed through longitudinal statistical modelling in renovated and non-renovated dwellings. based on the knowledge gained on the renovation rates of the non-profit housing stock we compare and evaluate future renovation rates through dynamic building stock modelling and empirical data validation. in essence, we examine the effect that the improvement of thermo-physical characteristics of dwellings has on efforts to make the existing housing stock almost emission-neutral by 2050, as advocated by the european commission since 2011.
