Towards very low energy buildings
This survey investigates the impacts associated with a wider introduction of very low energy buildings in five Member States of the European Union. In Denmark, France, Germany, The Netherlands, and United Kingdom, energy and CO2 savings were estimated going from current building regulations’ minimum energy performance requirements to the future national standard of very low energy buildings. Based on the estimated savings two different scenarios were calculated, one moving stepwise to very low energy buildings and one moving directly to the very low energy standard for all new buildings.
Furthermore, an overview is given that outlines established promotion instruments and also the barriers for introducing very low energy buildings in the selected countries.
