Energy Efficiency Ratings Aren’t Actually Predicting Energy Efficiency

Buildings with the highest U.K. performance ratings are using far more energy than those with the lowest ratings, according to recent data. It’s a disparity that shows the limitations of current green building standards.

There’s a secret dogging British buildings with some of the most coveted environmental ratings: On paper they’re green, but scratch the surface and they’re red hot. Buildings that have received the highest rating in the U.K. — an A Energy Performance Certificate — use more energy than some of their peers rated C, D, E or even F. 

This disparity between how buildings are designed and what their actual emissions are is widespread in the U.K., according to recent findings from the Better Buildings Partnership, which analyzed 2020 self-reported energy data provided for more than 1,100 commercial properties.
