Application of the Building Environmental Performance Model (BEPM) in Hong Kong

Since the energy crisis of 1973, engineers have endeavoured to implement energy conservation in buildings. Unfortunately, their efforts have often resulted in energy saving which ignores the fundamental delivery of indoor satisfaction. Hence, either energy is conserved sacrificing indoor environmental quality (IEQ), or additional energy is consumed for the cooling of occupancy space. These misconceptions have prompted the development of an integrated design and operation protocol based on a so-called Building Environmental Performance Model (BEPM).
