The dependences of temperatures and sensible heat flow at a roof and a ceiling on the solar reflectance of the roof were calculated. From the results, characteristics of the thermochromic materials necessary to improve the thermal conditions are discussed. It has been pointed out that vanadium dioxide is one of promising thermchoromic materials because it shows metal-insulator transitions with a critical temperature in the vicinity of room temperature, which may lead to large changes in solar reflectivity as a function of the temperature. We estimated the temperature dependence of the solar reflectance of vanadium dioxide by using data in previous literatures, and found that it is unsuitable for the improvements of the thermal conditions.}, pages = {18--25}, title = {サーモクロミック材料を用いた建築・都市の熱環境改善に関する研究}, volume = {2}, year = {2016} }
