How are Energy Savings measured in TX Standard Offer?
They use two processes in Texas to measure savings: One is a savings assumption determined before the work starts – either by “deemed savings” or “simplified savings”. • Deemed savings – These are taken from a list provided by the PUC of savings assumptions for specific measures installed in certain types of facilities (similar to the DEER database in CA, developed by the CEC). The measure installations were studied in the past and determined to save such and such, based on various assumptions. Example is a showerhead installed in multifamily residential. We know it saves x kWh and x kw – and we know it lasts 10 yrs. • Simplified savings is a measurement plan. For example we know that in office buildings on average their lights are on 4000 hrs. a year, and if they have air conditioning they’ll save this much more in air conditioning because of the reduced heat. Then we can go in and look at wattage – delta etc. Though it’s not deemed, we can calculate the savings at the beginning of th
