In recent years, there have been movements to consider traditional houses as local resources which are used for revitalizing the region. Traditional houses often do not have sufficient heat insulation performance, so it is necessary to renovate them. However, excessive renovation impairs the design of the traditional houses and loses their cultural values. In this paper, in order to verify renovation methods that secure the environmental performance while maintaining the design and cultural value, we analyze the thermal environment such as the skin heat performance and the heating load of traditional houses at Maezawa village in Fukushima prefecture.
