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?

Hi, 

I am modelling a CS building, the facade for the core (stairs, restroom, elevators, and all  non conditioned area) is 100% wall am I allowed to model it as non conditioned area but considering the wall to reduce the window to wall ratio?

Thanks

If all those spaces are not conditioned then any exterior walls associated with those spaces would not be considered a part of the exterior envelop. So you should model those spaces as unconditioned if they are unconditioned. You cannot count the wall area associated with these spaces in the window to wall ratio because that only include the envelop associated with conditioned spaces.
