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?

CS-2009 EAp2:Minimum Energy Performance

DCV requirement for high-occupancy areas

Project location :

Hello! We have a canteen project in Shanghai. The building has three floors, total GFA is 64,067 square feet. The baseline HVAC system type is system 6. In the second floor, there are only two air conditoned zones, dining area (12,588 sf2) and restroom (415 sf2). The dining area need to use DCV in baseline system. We have two questions about the model of eQUEST: 1. Do we need to use system 4 for the dining area and system 6 for the restroom? or both use system 6? or system 6 for the dining area and system 4 for the restroom? 2. Shall we use the minimum ventilation rates for the baseline system?

1. See Section G3.1.1. For a system 6 you need to model it in the baseline as a system per floor. You also must apply any of the applicable exceptions to G3.1.1. 2. The ventilation rates must be identical to the Proposed unless the Proposed has DCV.
