CS-2009 EAp2: Minimum Energy Performance
Dear all,
We know for the fact that for interior lighting:
"Trade-offs among building area types are permitted provided that the total installed interior lighting power does not exceed the interior lighting power allowance."
However, the requirement above is not explicitly stated for Exterior lighting, but section 9.4.5 discusses trade-offs and tradable surface.
My question is:
Can the installed exterior lighting power exceed the ASHRAE maximum allowance?
Thanks..

Exterior lighting is a mandatory provision so your project cannot exceed the ASHRAE maximum allowance.

Don't forget to include the 5% unrestricted allowance in your total allowable exterior lighting power. Be sure to include this in your Baseline model too.
