The gap between predicted and actual energy performance of new buildings is acknowledged to be significant. One aim of BREEAM is to encourage all those involved in the building design, construction, commissioning, facilities management and operation to take practical steps to close this performance gap. To this end, Guidance Note 32 describes the energy performance prediction and subsequent post-occupancy monitoring methodology for the BREEAM UK New Construction 2018 scheme.
