Résumé

For reducing the environmental load in the housing sector, the house renovation to improve the energy efficiency and the thermal comfort is desirable rather than the rebuilding after destruction. In this paper, the renovation method and the related element technologies for the small solar house, House T with air collector are described. The house located at a suburb of Takasaki (36.32 N, 139.01 E) was lived by a young couple and two small children. In order to increase the thermal resistance, the envelopes have been replaced by the well insulated exterior walls and roofs and the double pane windows. The roof is provided with the PVT pre-heating collectors of 54 m2 with a PV capacity of 5.2 kWp and the glazed air collectors of 10 m2 to be used for space heating and domestic hot water heating in heating season. In summer, the solar collectors are used for only domestic hot water heating. The heat pump air conditioners are used for auxiliary space heating and cooling. The heat pump is also used for auxiliary domestic hot water heating. As a result of the detailed simulation using EESLISM, it is expected that the total energy use of the renovated house will be reduce to 36% of the house before the renovation and the house will work as a net zero energy house using PV system.
