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

Compliance with ASHRAE 90.1 conflict with local norms

In Bulgaria we have a project, which if using the Building Area Method of ASHRAE 90.1-2007 meets lighting requirements; however, using the Space by Space Method requires adjustments to be made to several small rooms. We would like to use the Space by Space method because this will give us a lower baseline in the energy model and allow us to achieve 2-4 points more than the other method. Problem is that local lighting standards require lighting levels higher than those allowed using the Space by Space method. Has anyone faced this issue before? Our planned approach is to claim Special Circumstances and show how local norms prevent compliance with the Space by Space method for

Each space does not have to comply as lighting power density is not a mandatory provision. No need to claim special circumstances. As long as the total is lower you can claim the savings.
