In Egypt, adoption of the “International Style” of building has changed the profile of energy consumption, user aspirations and building technologies. Energy consumption has risen by 6- 7% per annum, with work places consuming 7% of the total energy consumption of the country. This paper investigated the use of double skin facades in hot arid areas’ using a dynamic building simulation software to predict the thermal and daylight performance of Double Skin facades in hot arid areas under sunny sky conditions. Previous simulations predict the possibility of reducing cooling demands in office buildings in hot arid areas if a selective double skin facade is used. The reductions on cooling loads in rooms range between 19%- 40% depending on the visual characteristics of the exterior glazing of the double skin façade. A possible 40% reduction in cooling loads is achieved when reflective glazing is used, on the exterior surface of the double skin. Daylight availability has been simulated using Radiance software. Results indicate that during direct solar radiation hours on the west and east facades, glare can not be avoided. But for providing appropriate levels of daylight for increasing productivity and the use of VDUs at the room depth a spectrally selective glazing is needed.
