Study on Compatibility of Energy Conservation and Thermal Comfort in Japanese House with High Air-tightness and Insulation equipped with H.V.A.C. System

The compatibility of energy conservation and thermal comfort in Japanese house with high air-tightness and insulation equipped with the whole-housing heating, ventilation and air conditioning (H.V.A.C.) system was examined by a numerical analysis. In addition to the present situation, several scenarios for achieving the compatibility were supposed. Thermal environment, thermal comfort and electricity consumption of H.V.A.C. system were analyzed throughout a year for each scenario. A combination of proper scenarios was found to be achieved the compatibility.
