We present the methodology used in developing an equation for estimating the cooling energy consumption of large commercial buildings. The equation was developed from a database of results generated from computer simulations using the DOE‐2 program. Factors accounted for by the equation include: part‐load performance of equipment, the number of cooling‐degree days, diversity of building operation, and the overall thermal transfer value of the building envelope. Also, the equation has been generalized to take into account the oversizing of the chiller from 110% to 160% of the design capacity. Parametric analyses using single‐ and multiple‐parameter variations validated the accuracy of the equation.
