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?

What guidelines should be used for district thermal energy systems in v4 when using option 1, specifically combined heat and power systems? The credit language does not clarify how it should be modeled and I could not find any guidance documents on USGBC's website. ASHRAE 90.1-2010 has a section on purchased heat but this section was excluded in v2009.

The DES modeling methodology has been incorporated into the Reference Guide for v4 and is now mandatory. It is under Further Explanation - Project Type Variations.
