Determination of the design energy consumption and design energy cost.

508.1 The Design Energy Consumption shall be calculated by modeling the Proposed Design using the same methods, assumptions, climate data, and simulation tool as were used to establish the Energy Cost Budget, except as explicitly stated in 509 through 534. The Design Energy Cost shall be calculated per Equation 508.1. Based on: DECOS m = DECON ml × ECOS ml + . . . + DECON mi × ECOS mi (Equation 508.1.2) Where: DECOS = The annual Design Energy Cost DECOS m = The monthly Design Energy Cost DECON mi = The monthly Design Energy Consumption of the i th type of energy ECOS mi = The monthly Energy Cost per unit of the i th type of energy The DECON mi shall be calculated from the first day through the last day of the month, inclusive.
