Abstract: The research and development of the energy-efficient coatings used in roof surface is presented. Firstly，three factors of energy-efficiency：reflectance，radiation，insulation are defined，and how membranes，reflective-pigments，infrared-radioactive pigments，heat-insulting pigments have an effect on the energy-efficiency performance of coatings is explained. Especially，the new type pigment known as CICP，which consists of the mixture of metal oxides and has a high reflectance in near-infrared region of solar spectrum is introduced.
