DEVELOPMENT OF A HYBRID HOUSE WITH THE PHOTOVOLTAIC SYSTEM AND EARTH HEAT-STORAGE SYSTEM

To make full use of surplus electricity at night and even off the peak electric demands in the daytime, a residence(the Clean Energy House) with the earth heat storage system and the photovoltaic system is bein g developed in Kumamoto City, Kyushu Island. The thermal performance o f the earth heat storage system including the house is predicted by nu merical simulations. The performance of the solar cells installed on t he roof of the house is predicted with the regression equations from s ome experimental studies conducted by the authors. It is predicted tha t the house can be air-conditioned only by surplus electricity at nigh t. The other electric demands such as lighting, cooking etc. can be me t by the photovoltaic system.
