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?

Domestic Water Booster Pump Energy in LEED

Has anyone successfully claim energy saving with domestic water booster pump? These pumps are often huge and there're no diversity profiles that I know of. The closest profile is the service hot water but it does not include the usage of the toilets. I'm thinking because the proposed building is required to have a 20%+ saving in domestic water, it will make sense if we at least save the pump energy with the same proportion and document it using exceptional calculation.

I have not seen it done, but it would certainly be possible using an exceptional calculation if the savings are significant enough to make a difference.
