FAQs about EAp2 :

Our project has a large process load—75%. Despite our efforts to make an efficient HVAC design, the cost savings are minimal. What can we do to earn this prerequisite and be eligible for LEED certification? Is there any flexibility in how we model the p

Our process load is higher than 25%. Do we have to justify that?

Do I need to justify the electrical and fuel rates I am using in my model?

Our local code references ASHRAE 90.1-2010. Should I use that for my documentation, or 90.1-2007?

Can I claim exterior lighting savings for canopy lighting even though a baseline model cannot include shading elements?

The project is built on a site with existing exterior lighting installed. How should this be accounted for?

NC-2009 EAp2:Minimum Energy Performance

unfinished space simulation

My building has four floors, and 4th flr is left empty for future use. I did not include it in simulation, so I got the comments from the reviewer: Revise the model as necessary to include all unfinished space, and to model any unfinished lighting, HVAC, and receptacle systems identically in the baseline and proposed case, consistent with ASHRAE 90.1 baseline requirements. On the other hand, the owner has identified the design of 4th flr will be the same as 3rd flr, current system has taken 4th flr into account. My question is how to simulation 4th flr in proposed model? Should I use the parameters on 3rd flr or refer to baseline model?

Technically the 4th floor must be modeled identically to the baseline even if the owner says that it will be fitted out identical to the 3rd. Projects can only claim credit for the current scope of work of the project, not for future scopes of work.
