Advanced facade material for urban heat island mitigation

A joint research team of Toyohashi University of Technology and Osaka City University has proposed two analytical models to evaluate the reflection directional characteristics of retro-reflective (RR) materials applied to building envelopes for urban heat island (UHI) mitigation, based on the measured data of optical experiments. The predication result of the anisotropic body of rotation of the normal distribution function (AND) model is more accurate than that of the original analytical model.
