The Impact of alternative window glazing types and a shading system on the daylighting of hospital patient rooms: Simulation analysis under a desert clear sky

Abstract

This paper aimed at identifying the most effective glazing type that suits different patient room layouts under desert clear skies. Year-round daylighting performance of three glazing types was compared with that of a 45 degree sun breaker for three different patient room layouts. Simulations were conducted for rooms facing south in Cairo, Egypt. The daylighting performance of the tested glazing types was less than that of a sun breaker. Electrochromic-60 and low E glazing were successful in the outboard bathroom design only, for large window sizes. The electrochromic-30 glass did not produce acceptable results in any of the tested cases.
