Through the review of the studies related to urban heat island countermeasures by building materials, their technical characteristic and performance are arranged and “the table on the effect of urban heat island countermeasures by building materials” is made. On the basis of their characteristics, the appropriate technical choice for the various areas and the various building uses is promoted. The evaluation tool is developed for estimating the performance of countermeasures from the viewpoint of public benefit, i.e. outdoor air temperature reduction and improvement of the thermal environment of human body in the outside space. When a user selects solar reflectance or evaporation efficiency, surface temperature, sensible heat flux and air temperature reduction at 13:00 and 21:00 can be estimated easily.
