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?

Dear All, I want to know that is it mandatory in LEED that we must have a fresh air in each occupied spaces of a project OR we can comply just by providing overall fresh air of the project according to ASHRAE. My second question is regarding to R-values of wall and roof for this is it mandatory that we must have a minimum R-values according to AHSRAE or if our design is not good mean we have low R-values then there is no issue regarding compliance for LEED, we know about heat gain will be more and HVAC load will increase but i want to know that we can proceed by taking low R-values as compare to ASHRAE.

Yes outside air is typically required for all occupied spaces. The R-value of the building envelop is not mandatory. You can install lower R-values. You are only required to meet the mandatory provisions and earn the minimum percent savings.
