Thermal emissivity is defined as the ratio of the total energy emitted by a surface to the total energy emitted by a black surface at the same temperature, and is a function of the radiation wavelength, the incidence angle, the surface temperatura, color, and its finishing touch. The goal of this research is to find out the effect of glass color to its thermal emissivity. The color of a glass is defined by its absorptivity. Glass with higher absorptivity has darker color. This research is carried out by using three variation of glass absorptivity and the necessary data to calculate the thermal emissivity of the glass are collected for each variation. The result is that thermal emissivity of a glass will be increasing as its absorptivity increases
