The aim of this article is to highlight the role of Building Information Modeling in minimizing the energy consumption of a building. To achieve this, a project was selected in Iraq and the annual energy consumption in this project was determined. Through the analysis of the building using building information modeling, it was found that the addition of some alternatives during implementation effectively contributes to reducing energy consumption . For example, the use of foam Material above roofs reduces the Energy Use Intensity (EUI) to (1,135 MJ/m²/year), Electricity (294,591 kWh), and Fuel (117,587 MJ) , and using Sand Stone in Wall Finishing reduces the Energy Use Intensity (EUI) to (1,116 MJ/m²/year), Electricity (228,898 kWh), and Fuel (496,223 MJ). Through these results, it appears that new materials must be incorporated into the building, as they are of high quality in thermal insulation and reduce energy consumption. By adding the alternative materials above, and from the results that appeared, it was found that these materials reduced the energy consumption of the building by a good percentage and thus obtaining a higher quality of the building by improving its performance.
