Very interesting. There was no mention of what lighting was used. This discipline is the easiest with which to save energy and increase productivity.
General office lighting is ceiling suspended with electronic ballasts and T5 tubes of 104 lumen/W efficacy. Compact fluorescent downlights are used in the common areas and T5 light fittings are used in the garage.
Congratulations on such a dramatic building.
The last sentence of your brief of Malaysia's Green Diamond states that the building uses fours times less energy than a typical office building. I'm not really sure what that means. Do you mean that it uses 1/4 of the average office building? If a typical building uses 1 MW, will MGD use 0.25MW. The way it's stated, 'four times less energy', would mean that MGD would create 3MW. (1MW *4)-1MW=-3MW. Just curious. Either way, it's good stuff.
The sentence should state that the Diamond Building uses one-quarter of the energy used by a typical Malaysian office building.
