MEASUREMENTS OF INDOOR THERMAL ENVIRONMENT AND ENERGY CONSUMPTION FOR SPACE HEATING IN 15 HOUSES IN TOHOKU DISTRICT DURING THE WINTER

Abstract

Measurements were carried out during the winter to evaluate the indoor climate and energy consumption of well-insulated detached houses equipped with central kerosene heating systems in Tohoku District. Indoor temperatures were found to be stable during the day and had small vertical temperature differences, excluding the cases where the systems were used improperly. The operation of the heating systems and energy consciousness vary depending on individual cases and accordingly the daily kerosene consumption range from 10 to 20L/day. The results clearly indicate that proper use of central heating system would save energy while maintaining the indoor thermal comfort.
