The Impact of Envelope Building Materials On The Thermal Comfort .Case of hot and dry climate

Abstract

Envelope Building materials play an important role in the architecture by providing the protection requirements, comfort, and technical performance while promoting an architectural language and an image. The impact of the building materials varies according to their physical, chemical, mechanical and thermal properties; Also, their interaction with the environmental factors: heat, humidity ... etc. Therefore choosing the right building materials is a key factor in achieving a certain level of comfort inside the building witch effect directly the energy use and consumption. In this study, we investigate the impact and the thermal behavior of different envelope materials, the most used materials; traditional and modern under the climatic conditions of Biskra a hot and arid climate. Also, we analyzed the results of a different simulation using “ecotect5.0” to performed thermal analysis and we used “opaque3.0” and “u-wert” to figure some envelope materials proprieties in order to choose the best material that ensures thermal comfort inside the building. The results show that choosing local massive materials and thermal insulation can achieve that to a certain degree.
