ENERGY SAVINGS OF A HOUSE WITH SOLAR HEATING, EARTH COOLING AND AIR-CIRCULATION

A new type of residence with solar heating, earth cooling and air circ ulation(the SEA House) has been proposed by the authors. In winter, th e house is heated by solar energy. Thermal insulation, het storage and air circulation are used to maintain the room temperature at a comfor table level and to reduce the energy demands for air-conditioning. In summer, the cooling tubes are used for the purpose of cooling the prop osed house. In this paper, the energy savings of SEA House are analyze d quantitatively. Comparing to the energy used for the air-conditionin g of the existing residential houses in Hokkaido, Sendai, Tokyo and Ka goshima, it is estimated that only 19%, 18%, 14% and 24% of energy are needed for the air-conditioning of the SEA House respectively.
