This report has provided an estimate of the baseline energy efficiency performance of Scotland's non-domestic buildings. The analysis has shown that there is considerable variation between the emissions intensity of different building types predicted by current EPC ratings. It is also clear that there are potential issues with using the current EPC band to monitor improvements in energy efficiency over time.
Adopting a building type benchmarking approach similar to that underpinning the comparative rating and creating a Scottish 'Comparative Asset Rating' may provide a clearer picture of changes in the energy efficiency of non-domestic buildings. This supports the approach advocated in the Energy Efficient Scotland Route Map on which the Scottish Government has recently consulted.
The analysis has also highlighted that further work will need to be undertaken with public sector partners to establish a specific baseline for public sector buildings.
