On the premise of protecting traditional styles of the dwellings, performances of thermal insulation and anti-radiation performances of traditional wooden dwellings of Tujia Minority in West Hunan and the interior thermal environment were improved through technological improvements in this paper. By improving wall construction technologies, thermal insulation boards and wooden planks were added to exterior walls of these dwellings. Furthermore, a two-layer air cavity formed and thus greatly improved thermal resistance of walls. Meanwhile, feasibility of improvement technologies proposed in this paper was validated by practical engineering tests and data detected before and after tests
