This measure involves plumbing a separate drain line system and control valves to allow the rinse cycle water to be used in the next wash cycle. The alternative requires laundry machines to operate to selectively direct rinse water to the inlet for other washers, or possibly a short term storage tank for use in the same machine in the next wash cycle. The wash cycle water would still be directed to the drain after each wash. Can we receive an initial indication from the council on whether this measure is worth developing an alternative method of analysis for, that is, does the council agree there is a potential for eligible energy costs savings for these items?
To document savings from this scheme, follow the ECB Exceptional Calculation Method. See Section 11.5 of the ASHRAE 90.1 User\'s Manual. The savings should be modeled as a discrete measure, and the resulting energy savings deducted from the DEC\'. This handles the "exceptional" savings in the same fashion as renewable energy. An engineering narrative must provide a theoretical basis and describe the expected interactive modes the measure will have with other systems of the basic simulation, and it shall describe all of the assumptions in the analog system model used to predict the savings. Advanced approval (prior to Application) of the proposed analog model and the predicted savings through this Credit Interpretation Request process is suggested. Applicable Internationally.
