Minimum energy efficiency standards for existing buildings

The clearest, strongest policy framework to support growth in the market for energy efficiency investments would be the introduction of more comprehensive minimum energy efficiency standards for all existing buildings. However, it is likely that this will remain a politically unacceptable option for some time. Therefore, we need to focus on expanding and strengthening existing standards, whilst at the same time learning from developments in Scotland, where there appears to be greater political will in this area.
