Abstract
The objective of this paper is to evaluate the applicability of multiple linear regression (MLR) models, based on engineering principles, to measured cooling energy consumption in commercial buildings (with either a dual-duct constant volume (DDCV) or a dual-duct variable air volume (VAV) system). The cooling energy consumption in five large commercial buildings in Texas was modeled and compared on both a daily and an hourly basis. The daily models showed higher coefficients of determination (R2) and lower coefficients of variation (CV) than the hourly models for both the DDCV and VAV systems. The outdoor dry-bulb and dew-point temperatures accounted for most of the variation in the cooling energy consumption. Compared to the base model (two-parameter model with outdoor dry-bulb as the only variable), all the MLR models showed a decrease in the CV between 10 and 66 percent, with an average decrease of about 33 percent, thus clearly indicating the superiority of MLR models.
