Abstract

As part of developing a generic rating system for green constructions, this research introducing a comparison between the credits owned by different international rating systems and the generic rating category developed for energy efficiency. One of Concordia University campus buildings in Canada has been simulated using the IES-VE simulation tool to calculate energy consumed applying different constraints of various rating systems against the developed one. The generic developed category describes international credits that suit those mentioned in LEED USA, BOMA BESt Canada, BREEAM UK, Greenship Indonesia, CASBEE Japan, BEAM Hong Kong, and Green Building Index Malaysia rating systems. By considering five rating systems, the case building fails to achieve the prerequisites of energy category in LEED USA and Canada, Greenship Indonesia, Green Building Index Malaysia, and the developed rating system, while it is rated in the case of Hong Kong. Hence, a comparison is conducted to stand for the amount of energy saving required to achieve the credits between each of the five selected rating systems and the developed one. The results show that the generic developed energy category surpasses the other rating systems as it requires more energy conservation for the building to be rated. The difference between the energy saving needed in the developed rating system and the existing ones ranging between 2,181.11 MWh /year, and 6,503.71 MWh /year.
