Documenting Rated Power for Gas Appliances

Only electric appliances are included in the Energy Star calculations.

I had this same question, and thought it important to close the loop on this forum thread so it's not hanging out there with old information. Anyhow, the USGBC issued an addendum to the 2009 LEED Reference Guide ID+C on Oct 12, 2012: Page 181, under 6. Calculations, "Add the following sentence to the end of Step 2: For gas equipment, convert BTU/h to watts to compare power usage." So gas equipment, if eligible for Energy Star, does need to be included and the energy use converted to watts.

At www.fishnick.com, you can download the LEED Prescriptive Measures *.xlsx spreadsheet that lists both baseline & prescriptive limits for both gas & electric equipment, along with approving agencies, of which Energy Star & CEE are two. Gas food service equipment, in general, is rarely over 40-45% efficient for cooking equipment like ovens & ranges, yet electric is often 65-70+ for most cooking, best case, induction, and 90+ for ware washing tank & booster heat. So I'm confused as to why we'd calculate with btu to watts to measure when there is a substantial difference between that and the baseline for same oven, for instance, but in electric instead of gas. Example: A full size convection oven, baseline idle rate 2KW (@65% baseline efficiency) and full size gas, 18000 btu in idle, (30% baseline efficiency.) But converting btu to watts bumps the KW to 5.275KW, and is still more than 2, even factoring efficiencies. Fryers are an even bigger spread. Plus, you have substantially more energy usage with gas due to vastly different ventilation requirements. In the case of ranges,it's almost half. But that's another can of worms!
