An EIU European survey of building sector executives commissioned by the GBPN in collaboration with BPIE finds that European real estate and construction executives are convinced that European legislation for energy efficiency and energy performance in buildings is a benefit for the building sector. While the financial crisis has set a downward trend to real estate valuations, the renovation of the existing building stock could be a means to reverse the tendency. Regulatory uncertainty seems to be the main barrier to increased energy efficiency investments.
