Abstract

The Computerized, Instrumented Residential Audit (CIRA) was developed to determine economically optimal mixes of energy-saving measures in existing residential buildings. To this purpose, a large number of heating and cooling loads and energy consumptions have to be calculated in a short time. In this paper, we present a simplified method of calculation that satisfies the requirements of speed and memory imposed by the microcomputer on which CIRA runs. The method is based on monthly calculations of degree-days and degree-nights for both heating and cooling seasons. The reference temperatures used in calculating the degree-days and degree-nights are derived from thermostat settings, solar and internal gains, and the thermal performance of the building envelope. Thermostat setbacks are handled by using the concept of effective thermal mass of the house. Performance variations of HVAC equipment with changes of part load and ambient conditions are taken into account using correlation curves based on experimental data. Degree-days and degree-nights for different reference temperatures are evaluated by using a climate-specific simple correlation with monthly average daily and nightly temperatures. Predictions obtained by this method and by DOE 2.1 are compared for several different houses and for four different climates in the United States.
