High Efficiency Small House in Musashino City, Tokyo

摘要

There has been great discussion recently about energy-saving houses. In summer in Japan, the outside temperature is high, and humidity is also high. Japanese houses have been built to be easy to live in, in summer. Traditional Japanese houses are not insulated and are open to the outside. These days, to build a thermal insulated house is recommended by the government. Because of the lack of experience in thermal insulation techniques, sometimes failures occur. We built a highly airtight and well thermally insulated house in Tokyo. Using new heating and cooling technology, the electricity costs for heating and cooling became lower. The characteristics of this house are as follows. An external thermal insulation compound system with thick wooden fiber board was used. Next, triple glass windows with wooden frames were used. Waterproof and porous sheeting was used for moisture control in the wall. In addition, to prevent solar heat gain in summer, external blinds were installed. Heating and cooling radiator panels were installed on the ground and first floors. Finally, inorganic paint was used for its fire resistance and to keep the room free of VOCs.
