This report gives an overview of the different policies and related boundary conditions in Norway, France, Germany and Italy and shows how they influence the spread of PEB concepts. National funding schemes and policies were analysed in regard to support renewable energy generation in buildings, the connection with the electric grid and neighbour buildings as well as the local energy market and environmental aspects.
Each EU country has its own building regulation and criteria for building insulation, efficiency of system technologies and share of renewable energy supply. The legal minimum requirements for nearly Zero Energy Buildings (nZEB) have strong disparities and are, except for Norway, behind the PEB standard. Nevertheless, several incentives are available for promoting PEB beyond the existing minimum legal requirements, even though the existing incentives did not increase the share of PEB significantly.
As a conclusion, the reports provide recommendations for policy makers for enhance the uptake of PEB. In particular, in order to achieve a real steering effect, a fixed CO2 target value for buildings is recommended instead of maintaining the previous assessment of reference buildings and primary energy requirement. At the same time the boundaries for the building assessment need to be expanded by the proportion of the embodied energy for building construction and the energy requirement for building operation, including the user appliances. For the envisioned coupling of the electricity, heating and mobility sectors, it is a crucial aspect to consider the introduction of district level approaches. In combination with variable energy pricing, districts can contribute to the grid stabilization by offering energy storage capacities and flexibility for energy demand and generation.
