The design of architecture energy conserving coatings with the metal double layers and the tripe layers is presented. A detailed discussion involves the design parameters as well as the transmittance and the reflectance properties. Uniformity of thicknesses of large area coatings is simulated by a computer and optimized distribution of evaporation sources is given. Experiments show that acceptable uniformity can be reached by using computer simulated distribution of evaporation sources. The measured spectral properties of such coating are presented.
