Summary

In this study, the development of housing renovation method and related element technologies for the solar house with air collector suitable for a typical two storied house is described. The house, House N is located at a suburb of Nagoya (35.17 N, 136.97 E). While the house has been lived by a family of four peoples, after the renovation, the house is supposed to be live by an elderly couple who will mainly use the spaces on the first floor (ground floor). Therefore, the renovation was limited for the first floor. In order to increase the thermal resistance, the envelopes have been replaced by the well insulated exterior walls and ceilings and the double pane windows. The first floor roof is provided with the glazed air collectors of 37 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 gas boiler is also used for auxiliary domestic hot water heating. The simulation study with a generalized simulator tool EESLISM was carried out in the design process of the renovation. The simulation results showed that the total heat loads of space heating, cooling and domestic hot water heating of the renovated house will be reduced by 55% for the existing house.
