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?

I am working on a building that will be owned operated by a charity in Australia. As a charity, they get free gas and very cheap electricity as a 'donation'. This means that their energy rates are not suitable to use in the PRM modelling and they do not access energy from they typical suppliers. It seems reasonable to just pick a major commercial supplier and use their publically posted rates for a similar sized supply for gas and electricity. Would this be a suitable process for the energy rates on this building?

You could use the published rates from the applicable utilities which serve this building or some sort of regional average rates published by the government. I would not "just pick" one, as it should be somehow related to the project if you are using a published utility rate. Hard to encourage saving energy when the rates are so cheap. Hopefully they have some other motivation.
