FAQs about EAp2 :

Do the required savings for this prerequisite (and credit) need to come only from building energy, or also process loads?

Our project doesn't have enough energy savings to earn the prerequisite. Can we get there by incorporating onsite renewables?

Our proposed design has insulation R-values that are below those prescribed by ASHRAE 90.1-2010. Can we still meet the prerequisite?

In the context of a refurbishment, are the existing luminaires exempt from complying with the exterior lighting power and/or exterior lighting control requirements stated in ASHRAE 90.1:2010 section 9?

 

Best regards

I don't think that the luminaires are required to be retrofitted with new lamps. Controls are a bit of a grey area for me, as there is a general principle that you do not have to bring up to code compliance any system that you are not touching, I could probably go wither way. I think that the existing exterior lights would contribute to the exterior lighting power requirements as a part of the installed exterior lighting power.
