Optical simulation of laminated glass

Tomás Baenas Tormo

In the design phase of a glazing system, multiple laminated glass configurations may be conceived for architectural purposes (mainly related to aesthetical issues, energy efficiency, safety and security and/or acoustic insulation). Therefore, the availability of computational simulations of optical and thermal properties of laminated glass as a function of the properties of its constituents (glass panes, polymeric films, selective coatings) may be of great utility. Standardised procedures for this kind of calculations are still in preparation. The theoretical study of laminated glass with internal selective coatings is especially relevant due to the introduction of reflectivity within the multilayer optical system. In this work, the simulation results obtained are compared with UV-VIS-NIR spectrophotometric measurements. Numerical simulations have been performed with DISAC software (www.disac.es).
