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?

Healthcare-v4 EAp2:Minimum energy performance

Water Cooled Chiller Make Up Water Cost Baseline

Hi,

Our project is using air cooled chillers as our region has water shortage. Our comparison with water cooled chiller for baseline is penalizing us big time but we believe this is not a fair comparison as we are saving huge amount of water.

In regards to above, the baseline energy cost should include water cost to have a fair comparison. Is it possible for us to report lower energy consumption than baseline but have better cost than baseline to achieve mandatory compliance?

This issue has been raised multiple times by projects primarily in the Middle East and I think such comparisons are not allowed. You could try to make your case with the reviewer to justify the rate difference but Appendix G is very clear about using identical rates.
