Title-24 Compliance (Conditioned & Unconditioned spaces)

2 posts / 0 new
Last post

I've performed a preliminary Title-24 compliance (Envelope/Mechanical/Lighting) for a building with conditioned and unconditioned spaces. Although I've assigned unconditioned spaces to a system, the Preliminary report's General Information lists 12 zones as Unconditioned & 9 zones as Conditioned, however, the Unconditioned Floor Area is zero square feet. Additionally, the lighting for the unconditioned space is not included in the Preliminary report's Total Building lighting Watts compliance. Can someone help me get eQUEST to perform lighting calculations for the conditioned & unconditioned spaces? I've included the equest model if needed. Thanks, Mike Schaefer, PE, LEED AP

I have not looked at your input files but here are a couple thoughts: * eQUEST has conditioned/unconditioned inputs for both the spaces and for the zones so make sure these are set accordingly in both places. I have not payed close attention to unconditioned areas in the T-24 reports so I'm not sure if those are reported correctly. * The Title 24 ACM manual explicitly says to not include lighting power for unconditioned spaces in the standard model. I believe that if you include lighting for these spaces in your proposed model, that you're simply taking an energy hit since that power is set to 0 in the baseline whereas eQUEST keeps your proposed lighting. I'm pretty sure about that last part but you should check your input files to confirm. For a normal building, this is probably only a minor impact, but sometimes you need every bit of savings you can get... Good luck. Hwakong
