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

Can SHGC be higher in the proposed than in the baseline model?

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

New Table 1.4 Spreadsheet SI-Units

Dear all, we gladly noticed that the Table 1.4 spreadsheet improved a lot. Now it is more like a interactive toolkit. Unfortunately most of the items are just in IP-Units available. That makes this kit very error-prone because we are working in SI-Units and have to transfer everything (e.g. U-Values). I asked the GBCI if a SI-Unit-implementation is planned - they replied "As far as we know, this is not in development". We would appreciate, if this will be developed shortly, also becaused SI-units are generaly admitted by the USGBC. I would like to ask you if you are also concerned by this to ask again and again for it, to put some pressure on it. Merci! regards, Johannes

I would second that as well would 40% of all LEED projects being outside of the states (i.e. using the metric system...funny, when I think about it, just the states still uses IP).

We do remain backward when it comes to measuring things. If the project does not do the conversion then the reviewer must do it since the reviewers are mostly familiar with the IP units. USGBC has a conversion tool and we developed our own spreadsheet to help as well. Ideally the form would contain both and you could enter one or the other and it would do the conversion.
