Benchmark energy performance value – clarification - KBCN1724
The benchmark energy performance value is a performance level which achieves the
median performance within a local energy performance standard's range of values.
Example
In the UK, assets are rated using Energy Performance Certificates (EPCs).
Assets are rated from A to G. The median performance is a D rating. The D rating itself represents a range of performance values.
The benchmark energy performance value is the value at the middle of the D rating.

Sometimes the boundaries for energy performance ratings for meeting building regulations are split in a different way to the BREEAM assessment boundary.
If the BREEAM assessment boundary covers multiple energy ratings, for this issue only enter data on the rating which covers the largest NIA (Net Internal Area).
