Mr. Chris Hughes:

There will be a harmonisation of the BER scheme to simplify the scale. Currently, it goes from A1, A2 and A3 all the way to G. It will be simplified to run from A to G. A high-performance building today will still be a high-performance building in the future. A zero-emissions building will be A and G will be the 15% of poor-rated buildings, with an equal division across the other classifications.
