Alternative compliance procedure.
CFR · 2024-01-01 · US · Title 10
(a) If a proposed building design includes unusual or innovative energy conservation measures which are not covered by the COSTSAFR program, the Federal agency shall determine whether that design meets or exceeds the applicable energy consumption goal in compliance with the procedures set forth in this section. (b) The Federal agency shall determine the estimated discounted energy cost for the COSTSAFR prototype building design, which is the most similar of the COSTSAFR prototypes to the proposed building design, by— (1) Printing out the COSTSAFR compliance forms for the prototype showing the points attributable to levels of various energy conservation measures; (2) Calculating the estimated unit energy cost on the compliance forms, on the basis of selecting the optimum levels on the compliance forms or otherwise in the User's Manual for each energy conservation measure; and (3) Multiplying the estimated unit energy cost by 100. (c) The Federal agency shall determine the estimated discounted energy cost for the proposed building design by— (1) Estimating the heating and cooling total annual coil loads of the proposed building design with the DOE 2.1C computer program on the basis of input assumptions including— (i) Shading coefficients of 0.6 for summer and 0.8 for winter; (ii) Thermostat setpoints of 78 degrees Fahrenheit for cooling, 70 degrees Fahrenheit for heating (6 am to 12 midnight), and 60 degrees Fahrenheit for Night Setback (12 midnight to 6 am, except for houses w
