Building Energy Management in Airport Construction Projects Utilizing BIM Technique

Abstract

Building Information Modeling (BIM) is one of the modern technologies that has become widely applied in many aspects of construction projects and energy management. This paper aims to use modern technologies in designing and constructing airports to control energy consumption, know the possible strategies to obtain the lowest consumption and the most appropriate cost, and compare simulated electrical energy outcomes with actual electrical energy consumption. By investigating the impact of sun path analysis on energy performance, analysis and evaluation of energy performance, and water usage. Analysis using BIM technology tools. As the airports are the largest part of buildings in energy consumption and due to the lack of research available in Iraq on how to obtain optimal use of the consumption of available electricity and water efficiency in Airport projects that can be used to obtain an environmentally and economically sustainable airport. Using BIM technology and the associated programs, it is possible to know the optimal strategies in terms of economic terms. The environment in the early stages of the life of the project. The idea of this study applied to one terminal of Baghdad international airport. The results illustrate that BIM is very useful to perform various analyses that help find different strategies for improving the project’s energy efficiency, such as sun path analysis and GBS tool based on BIM helpful technology tool to energy analysis. The result illustrates that most energy electricity consumption goes for cooling space with consumption around 63871 kWh in August month and most fuel consumption for the purpose space heat with consumption around 1409261 MJ in January month and where indoor water-saving around (23.7%). GBS tool based on BIM technology is an effective tool that can help designers and architects to energy performance assessment and calculate energy costs in the early design stage were help in finding the best solutions that contribute to improving energy efficiency in the early stages of the project life cycle.
