Abstract—Global warming, which is also referred as climate change, is considered as one of the critical environmental issues nowadays that comes with anticipated effects of increasing global temperatures. Reactions to this climate change and concern about its effects are also increasing. Thus, possible responses to this change are being taken, including different ways such as future climate engineering. Therefore, this work intends to observe and discuss the impact of greenery strategies and wind speed for the urban area with high rise buildings and maximum sky view factor on the urban microclimate. The mean radiant temperature is used as the indicator for the thermal comfort. The study was conducted on the hottest day in summer in Baghdad city by the evaluation of vegetation, mean radiant temperature to assess the human comfort in high rise buildings area. The assessment was done on the hottest day where the mean radiant temperature, sky view factor, air temperature distributions have been analysed using ENVI-met version 4.0 which allows simulating three-dimension geometrical configuration that performs an essential role in controlling longwave radiation heat loss, which shows the effect of different patterns of greenery strategies on the climate in the area of study. As a result of this modelling process and among the four scenarios that were simulated, the scenario of green ground was found as an effective solution to provide thermal comfort during summer time in the study area.

Index Terms—Global warming, vegetation, thermal comfort, mean radiant temperature, ENVI-met.
