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 everyone, Reading the v4 reference guide, it seems that the default process energy being 25% of total energy cost for the baseline disappeared from the requirements. Have you also noticed it? is it not a requirement anymore?

Marcus Sheffer has already commented this issue. Actually, such a requirement has never existed. Both in LEED 2009 and in LEED v. 4 you have to model the process energy considering "the building type or space type category" (Tab. G3.1-12). The best situation is when you can consider the real process power (with the real schedules) that is going to be installed in the building. For LEED 2009 when the process energy is less than 25% of total energy cost for the baseline model you have to provide a narrative. Best Regards
