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.
