Outline of Final Research Achievements

This study aims to propose snow melting method by using the thermal radiation and the control of the reflection of the solar radiation.
The result of this study can be summarized as follows. Outdoor experiments of the snow melting on the eaves had been conducted and the influence of the difference of the solar reflectance of the building material on the melting snow was revealed. The time difference of snow melting has been reached up to 50 hours or more induced by specification difference. As the result of the radiation analysis and experiments, the combination of enhanced reflectivity of solar radiation of the wall and the eaves with high absorptance has been identified as specifications with the advantage of snow melting.
