Optimization of the Optical Performance of TiO2/Ag/TiO2 Multilayers for Warm Climates

Article Preview

Abstract:

The optical performance of the heat mirror for warm climates was proposed, and a parameter Dx which equals the ratio of solar transmission to visible transmission was defined. To make the Dx as low as possible, the thicknesses of the films for TiO2/Ag/TiO2 multilayers were optimized through computer simulation. A TiO2 (140 nm)/Ag (16 nm)/TiO2 (140 nm) structure optimized for 16-nm Ag has a maximum decrease in Dx value (from 0.75 to 0.51), which possesses excellent building energy efficiency.
