This video is about how to achieve energy efficiency building based from ASHRAE Standard 90.1.
The latest is ASHRAE Standard 90.1-2007.This standard is a requirement for Green Building certification such as LEED.
For Malaysia GBI, it is not a requirement to comply to ASHRAE 90.1 but the building need to comply with MS1525 (if related to the targeted point).
ASHRAE 90.1:2007 is more stringent than MS1525. ( more costly)
For example, lighting power density for :-
ASHRAE 90.1 : 2007 = 12 W/m2
MS1525 : 2007 = 15 W/m2
ASHRAE Standard 90.1:2007
