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

Hi, I have a project in the UK. For schemes such as BREEAM we use a SBEM - BRUKL output for the energy credits. Does anyone know if this is compliant to use for LEED as well? Or is an ASHRAE model still required? Thanks

I am not aware that any of the European standards have demonstrated equivalence to 90.1. This is a pretty involved process and would usually be undertaken by a a governmental agency or perhaps a nonprofit with funding to do so. The issue in LEED is that equivalency needs to be demonstrated to ensure that the percent savings and the point scale is associated with a baseline that would produce similar or conservative results.

Don't think SBEM meets the minimum requirement of ASHRAE 90.1 Appendix G for modeling software (G2.2), such as 8760 hours per year, thermal mass effects, precisely defined and manipulated HVAC systems etc.

Are there any updates on this? Is this now a possibility? Thanks in advance
