PARTIAL INSULATION RENOVATION PROJECT AT JAPANESE TRADITIONAL WOODEN HOUSE

Abstract

Japanese traditional wooden houses are designed to spend cool in summer by promoting as much wind flow through the house as possible. But, these houses have low thermal insulation performance. In this paper, we proposed a partial insulation renovation for Japanese traditional house. We applied this method to Kyo-machiya and verified the effect of the renovation. Insulated sliding-doors were developed by using Japanese traditional techniques. As the results, the thermal environment in the insulated compartment was improved without changing the original interior design. The insulated sliding-doors were effective for improvement of the surface temperature and of the air-tightness.
