PERFORMANCE OF A LOW-ENERGY HOUSE IN A MILD COOLING SEASON .1. THERMAL PERFORMANCE OF THE HOUSE

A low-energy house located in Halifax, Canada, was monitored for a yea r using a computerized data acquisition system. Data on indoor and out door temperatures, relative humidities, and power consumption were col lected for a whole year. The results of the analysis of cooling season data are presented. It was found that indoor temperature variations i n the house were generally small, indicating a high level of comfort. The cooling load, and the cooling energy requirement of the house were low owing to the high level of insulation, and could further be reduc ed by increasing the thermostat setting. This however would reduce the comfort level in the house. Temperature set-up during unoccupied peri ods did not reduce daily cooling energy requirement, and addition of a n economizer control would not be feasible owing to the small magnitud e of potential savings.
