International Conference | Bari - Lecce, Italy Session X-XI DESIGNING A PASSIVE AUTOMOBILE SHOWROOM IN HOT CLIMATIC CONDITIONS Iyad Abdaljawad1 & Hasim Altan1 1 Sustainable Design of the Built Environment, Faculty of Engineering & IT, British University of Dubai, UAE, [email protected] / [email protected] Abstract Passive design contributes to environmentally responsive design of buildings that integrates with the surrounding environment and at the same time meets the human comfort, also helping to reduce consumptions of both cooling and heating energy. Using passive strategies depends on the project context which refers to the renewable sustainable resources and the criteria available in each region, while they are adopted to reduce energy consistently and to cut down the carbon footprint in order to also help enhancing the environment. Building envelope impacts on energy performance and can influence in reducing amounts of artificial lighting and mechanical ventilation remarkably in passive designs. This paper investigates energy performance of an automobile showroom and compares between the existing case and the improved case in Dubai, UAE, considering the hot climatic conditions. IES Virtual Environment (VE) software was used to assess the overall building performance. Simulation results were compared before and after the passive cooling strategies applied accordingly. Glazing, insulation materials, and building envelope were the main elements examined in the study. Daylight factors, CO2 emissions, thermal massing and building cooling loads were evaluated before and after applying passive strategies. The simulation conducted has shown that the passive performance reduced up to 36% of the total electrical consumption. Strategies were applied on the building accordingly to improve the design form passively, to fulfil the needs for the variety of functions of the building, to enhance the indoor spaces quality, and to reduce the annual amount of mechanical cooling loads to save energy.
