EnerPHit Standard
BG 87/2024, Useful Information Guide, written by Chin Hang “Kay” Lam and published by BSRIA in 2024, defines the EnerPHit Standard as: ‘A building standard that was developed by the Passive House Institute for existing buildings which would only achieve the Passive House Standard with great difficulty. Passive House components are used for EnerPHit buildings so that except for the slightly higher energy demand, these buildings can benefit
from almost all the advantages of a Passive House.’
