NC-2009 EAp2:Minimum Energy Performance

Unconditioned Spaces

While modeling the building in the space-by-space method, there are a couple of closets that are not conditioned, therefore have been model as unconditioned in TRACE 700. These spaces have lights, and is contributing to the lighting load. The energy simulation shows that there is a little lighting load from these spaces. On the LEED form there isn't an unconditioned space lighting load. Is this lighting load to be added to the interior lighting, or was the simulation run incorrectly, and need to be corrected to remove this load?

All the lighting must be included. What is the function of the closets? Typically they are storage or mechanical/electrical.

They are just for storage. The electrical rooms end up requiring supplemental cooling, the the mechanical rooms are just heat pump closets with indirect conditioning.
