This paper presents the development and use of a simplified model for predicting the cumulative sensible cooling load for a single-zone building. Cooling load predictions are compared to results obtained using the detailed Thermal Analysis Research Program (TARP), a sophisticated computer model previously developed at the National Bureau of Standards. Weekly sensible cooling loads, predicted by the simplified model, agreed to within 3% of the values predicted by TARP.

The investigation described within this paper reveals that the effect of thermal mass could not be incorporated within a simplified model due to complex interactions between the structure of a building, furnishings within the building, and climatic conditions.
