Abstract: Iraq is one of the countries facing a noticeable rise in temperatures caused by climate change in recent decades. This generated an increased feeling of thermal discomfort among humans. Previous studies submitted many research works in the field of outdoor thermal comfort in cities, but the study of the role of the Iraqi green buildings code in improving outdoor thermal comfort for the residential complex was not adequately addressed, especially at the local level, which was the research problem. The research proposes that the adoption of Iraq Green Buildings code will increase outdoor thermal comfort in residential complexes. The Bismayah residential complex in Baghdad was chosen for this study and tested with ENVI-MET 4.4.2 software. The simulation is based on PMV assessments performed before and after the green building code was implemented. It was found that the implementation of green buildings code improved by increasing the percentage of vegetation, trees and water bodies. Also the change in façade materials to light colours, and the type of pavement materials. had a significant role in increased (PMV) during the day by about two degrees from the model before the change.
