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?

NC-v4 EAp2:Minimum energy performance

Baseline heating source where no fossil fuel is provided to building

Hi,

We are modeling a 47,000 sf 2 story office bldg in climate zone 3C. The baseline is system 5 w/ fossil fuel heat. This project will not have any fossil fuel onsite. It looks like the system should now switch to system 6 with an electric heating baseline but I cannot find the reference for this exception when no fossil fuel is available to the building.

Whether fossil fuels are available to the building is not an issue. The selection of the appropriate baseline system is based on the heating fuel source in the proposed design. If it is electric then you use system 6.
