Cr2O3is the host component and the adding mixtures of Al2O3, V2O5and TiO2as the guest components. The composition denoted by T1 composes of Cr2O3, TiO2, Al2O3and V2O5are 80, 4, 14 and 2 wt%, respectively, gives near infrared solar reflectance of 82.8%. T1 green pigments were prepared for ceramic cool tile roofs (denoted by T1 cool roof). The comparison study on the effectiveness of T1 ceramic cool roofs and a commercial ceramic cool tile roofs (denoted by C cool roof) show that the T1 cool roof has given a better result by keeping the tested room about 4 °C cooler. © (2013) Trans Tech Publications, Switzerland.Mahidol UniversityEngineeringConference PaperSCOPUS10.4028/www.scientific.net/AMR.770.30
