AbstractMost Iraqi cities suffer from a stark negligence in achieving equilibrium between the constructed objects and their effects on local climate, especially in providing green areas. This led to disturbing the natural equilibrium in the urban environmental system, which in turn led to an increase in temperature degrees inside the cities, resulting in the cities to move outside of the temporal comfort boundaries. Therefore, this research studies one of the technologies that reduce this temporal effect that was generated by the shortage of green areas in the city, which is the green roofs technology. The green roofs are important technologies that have effects on the local climate, they provide temporal comfort inside the building and outside of it, therefore, they reduce the effect of heat island especially at locations with hot and dry climate, however, the efficiency of the plants in green roofs differs according to the climatic nature and the location specifics. From here, the research problem was assigned about “The lack of a clear picture about the rule that green roofs play in environmental solutions in buildings”, and the object was assigned as “Creating a clear and measurable notion about the rule that green roofs play in the climatic aspects for buildings within the urban level” while the research hypothesis is “The green roofs have a positive rule in improving the environmental performance of buildings”..
