Abstract

In this study, we analyzed the relationship between four elements: long-wave radiation, the direction of the building, BVR (Building View Ratio), and cloud amount. We examined how long-wave radiations surrounding a building influences the perception of heat in the summer. The results are as follows. (1) Long-wave radiation and BVR are highly correlated regardless of geographical direction. (2) Especially, during dawn in a clear day, areas with high BVR observed high levels of long-wave radiation. (3) This correlation suggests that higher BVR in urban areas will result in a greater number of tropical nights.
