The study aims to optimize the envelope for office building in hot arid climate, in order to achieve thermal and visual comfort, energy efficiency, and make use of renewable energy. The study analysed the outdoor and indoor climatic conditions, taking different case studies to understand the problems of overheating, discomfort, and the energy needed to achieve indoor environment quality. The effects of applying different technologies and design strategies using computer simulation programs (Ecotect and Trnsys) on the comfort and energy efficiency were evaluated. The evaluations of technologies included: glazing performance, shading and solar control, insulation and thermal mass, and P.V integrated facades, as well as design strategies included: opaque transparent ratio, orientation, and natural day and night ventilation. The results showed a significant decrease in cooling loads and energy for lighting, and increase in thermal and visual comforts. These design strategies and technologies are suitable for architects and buildings facades engineers to be aware of the environmental performance of building facades and sustainable design, which adapt to the climatic conditions.

Abstract
The study aims to optimize the envelope for office building in hot arid climate, in order to achieve thermal and visual comfort, energy efficiency, and make use of renewable energy. The study analysed the outdoor and indoor climatic conditions, taking different case studies to understand the problems of overheating, discomfort, and the energy needed to achieve indoor environment quality. The effects of applying different technologies and design strategies using computer simulation programs (Ecotect and Trnsys) on the comfort and energy efficiency were evaluated. The evaluations of technologies included: glazing performance, shading and solar control, insulation and thermal mass, and P.V integrated facades, as well as design strategies included: opaque transparent ratio, orientation, and natural day and night ventilation. The results showed a significant decrease in cooling loads and energy for lighting, and increase in thermal and visual comforts. These design strategies and technologies are suitable for architects and buildings facades engineers to be aware of the environmental performance of building facades and sustainable design, which adapt to the climatic conditions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
