抄録

This paper presents the effect of ‘retro-reflection film’ improving not only indoor but also outdoor radiative environment. Solar heat shielding against solar radiation over the entire building envelope is one of the most effective measures for achieving air conditioning energy savings. On the other hand, solar radiation from the mirror reflection of a heat-shielded building envelope by Low-E glass for example, deteriorates the street radiative environment. These facts indicate that retro-reflection is an effective method to improve the current situation. We propose a newly developed heat-shielding film, which possesses a retro-reflective property and a wavelength-selection property, while having the same degree of transparency as usual glass. The proposed film embodies an innovative heat-shielding technique that makes it possible to effectively return solar radiation toward the sky, while minimizing the secondary effects to other buildings, to the ground, and so on. In order to verify these effects, several aspects of quantitative evaluation are demonstrated.
