Utilize BIM Technology for Achieving Sustainable Terminal Building of Airport

Abstract

The airport industry is the world's largest energy consumer, which negatively influences the environment. In this article, the research methodology is applied Building Information Modeling (BIM) technology in 3D simulation and energy analysis. This research aims to use BIM technology and its advantages in improving the sustainability of the building through the use of solar panels and adding different alternatives to the building to see the extent of their contribution to reducing the energy used and the percentage of emissions. The case study of this research was applied in one terminal of the Baghdad international airport. The researcher found that using BIM technology helps a lot in improving energy performance in various ways, improving the percentage of emissions, and controlling them during the design stage. The results concluded that applying BIM technology, use photovoltaic (PV) panels reduced annual energy consumption by around 45, 13, and 23% when operating in different places of the roof and achieves cost-saving about (258,601, 76,471, and 130,483 $/year, respectively, total electricity consumption equal to (4,466 MWh/year and annual fuel consumption are 9,472, 795 MJ/year) this results reduced by using different alternatives. The use of double glazing, foam material, and replacing part of the curtain wall with a block wall is the most effective alternative in improve energy saving and reduce CO2 emissions.
