    Abstract

    The housing section in Japan is promoting the introduction of renewable energy. However, it has problems such as surplus generation during a low load period and there could be a rise in voltage due to reversed power flow. Therefore, there is a need to use the generated surplus energy effectively. The aim of this study is to evaluate the effects of the precooling and preheating operation. To this end, we measured indoor environmental factors, energy consumption, and skin surface temperature and heat loss using a thermal manikin under ten conditions with different air conditioning in house with higher heat capacity.
