NC-2009 EAp2:Minimum Energy Performance

Utility Service Changed During Construction

Hello - My project submitted, and received approval, of our energy model based on natural gas DHW heating and everything else electric. I recently discovered that they installed all electric in the building due to issues with the local utility provider. (This is a light commercial project for a large franchise). We are also pursuing M&V. I now have conflicting information between my design and construction submissions. It seems there are three options: 1) modify design credits to installed - expensive!, 2) submit construction credit with installed condition and add a note of explanation - risk being rejected, or 3) base the construction credit on the designed system - reduces the value of the credit to the project. How do I proceed?

When doing a split submission you are required to state that nothing changed during construction to affect previously approved credits when you submit your construction credits. You are technically required to update the energy model to reflect what was built. This is why we always defer the energy model until the construction submission. When it comes to M&V the whole idea is to verify predicted savings. So if you already know your prediction is flawed, the correct action is pretty obvious( #1). If you do #2 it would automatically open your previously approved energy model to further review. If you do #3 you will knowingly be submitting inaccurate information.

Great, thank you so much. I thought that was the answer, but needed to verify it for my project team. Very helpful and I appreciate the quick response!
