Practice Note for Authorized Persons, Registered Structural Engineers and Registered Geotechnical Engineers – Energy Efficiency of Buildings Building (Energy Efficiency) Regulation
實體風險The Building (Energy Efficiency) Regulation (B(EE)R) imposes energy efficiency requirements for buildings. It aims at reducing heat transfer through the building envelope thus saving the electricity consumption for air-conditioning by requiring the external walls and roofs of a commercial or hotel building to be designed and constructed to have a suitable Overall Thermal Transfer Value (OTTV). The suitable level of OTTV and the methodology of OTTV calculations are specified in the Code of Practice for Overall Thermal Transfer Value in Buildings 1995 (the OTTV Code) published by the Buildings Department (BD).
