HEMSによる家庭用冷暖房・照明エネルギーの削減効果の検証  [in Japanese] VALIDATION OF ENERGY CONSERVATION EFFECT FOR HOUSEHOLD USING HEMS  [in Japanese]

This study shows the results on a validation of energy conservation effect for household using HEMS. The experiment was carried out in 100 detached houses in Hiroshima. Using a signal of human body detection sensor, the air-conditioner control by HEMS performs regulation of set point temperature, and a stop of the air-conditioner at the absence time, and acquires the energy conservation effect. Lighting is turned on by the signal of the detection sensor and an illuminometer. Although the annual energy conservation effect by air-conditioner control was a maximum of 13%, the average of 100 households is 2.3% and a so much effect cannot be expected. The energy conservation effect by lighting control of a passage was presumed to be 4.3%. The energy conservation effect by HEMS to the energy consumption of the whole building was only 0.6%.
