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

EA-Optimize Energy Performance

Hello,

We have an energy model for the building and are at 22% savings-9 points. My clients wants to confirm why the on site renewable energy is not include in the calculation to get more savings. In my understanding For projects with on-site renewable energy systems
and/or site-recovered energy costs, the associated cost savings are not included in the proposed design case, and therefore the team would need to pursue the performance rating method detailed in ASHRAE 90.1 Appendix G of the reference standard.

How can I confirm that the renewable energy is not part of the savings for the building?

Projects doing an energy model must use Appendix G to determine the baseline energy model. The proposed model is as designed. Renewable energy can count toward the calculations to increase the savings related to this credit. What changed for v4 is that the project must meet the prerequisite requirements without renewables. The renewables are then applied to the savings when determining the points for this credit.

Hi, We're trying to satisfy EA Prerequisite - Minimum Energy Performance under LEED NC V4, do we need to provide "Minimum Energy Performance Calculators" or can we upload our Building Energy Analysis Report (T-24) from EnergyPro software in lieu of this requirement? Appreciate any advise please.. thanks

I think you need to provide the MEPC for v4 projects. I may not have seen the reporting from the latest version EnergyPro but it it does not look like the MEPC then you probably need to provide the MEPC. Anyone submit a v4 project following T24?
