Study on Roof Tile’s Colors in Malaysia for Development of new Anti-warming Roof Tiles with Higher Solar Reflectance Index (SRI)

This paper presents the preliminary findings of on going study intended to develop a cool house by introducing roofing materials with higher Solar Reflectance Index (SRI). SRI is a composed measure that accounts for surface’s solar reflectance and emittance. It is measured on a unitless scale from 0...
