Application of Sustainable Passive Cooling in Hot -Dry Climate Zones

Abstract

The research is concerned with the applications of sustainable passive cooling in hot- dry climate zones. Its deals with sustainable passive cooling techniques, and how they are applied in private residential buildings. The research aims to investigate thermal comfort for occupants of residential buildings in hot -dry climate zones, and to get the suit passive cooling techniques to our environment, also it aims to examine ways that reduce energy consumption and rush out in consideration of renewable energy sources (wind, solar energy), to study how to apply these methods in both the design and planning stages of residential buildings in hot- dry climate zones, to activate sustainable passive cooling techniques, and provide ways to improve indoor air quality in all seasons of the year. The research method is based on a comparison between local models (in Greater Khartoum, area of the study) and global models to arrive at the most important results of the search. In conclusion, the research shed light on the current situation in the area of the study, and concentrating on a local residential model (Architect Osman Elkheir own house). The research concluded with some results, the most important of which are to promote passive cooling and sustainability applications by using renewable energies in the study area (sun, wind, ..) and reducing the usage of the modern building materials of concrete, which increase the amount of incoming heat to the building, and the development of the use of local building materials in a modern way. In conclusion, the research has recommendations for the case study and other public of the ability to apply the passive cooling techniques in the case study area such; as taking into account the climatic design requirements in the study area (hot dry climate), develop natural techniques, try to apply other techniques and provide support for its application, application of sustainability concepts in the area of study and make it part of the basic laws either in designing process or planning.
