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

System 8 Fan Power Allowance

Dear All, I have a system 8 (VAV with PFP boxes) baseline and I had a reviewer's comment stating that: "The interior fan demand reported in Table EAp2-4 for the Baseline case exceeds the Baseline fan power allowance reported in the Supplemental Table 1.4". Knowing that the values entered to Table EAp2-4 were enduse values generated by the simulation tool for all vent fans (including zones pfp), and Knowing that I tried changing Table 14 System from VAV with pfp to VAV with reheat to find that fan power allowance didn't decrease; meaning that the table isn't counting for the zones' PFP powers; Should I supply a narrative explaining that the PFP fan powers did cause this increase, or there is a certain check that I'am missing?
