Abstract
The increase in the number of people living in cities day by day causes both an increase in people's demands and an increase in the hard floors and building surfaces in cities. This increase also increases the urban heat island formation and affects the outdoor thermal comfort of people. Most of the work done today is on improving the climate. It is important that green areas should be increased in order for people to roam more comfortably in the outdoors and that improvement works should be done by reducing hard floors.
This study was carried out in order to improve the outdoor thermal comfort in the Yıldızkent district, where urbanization is gradually increasing in Erzurum. For the study, a site close to the TÜBİTAK measurement station was selected and the study was completed by increasing the plants at different rates. In the site, which is currently only grassy, 10%, 20% and 30% plant cover was added and analyzes were made in the ENVI-met climate model. According to the results of the study, Scenario 3, which is the scenario with 30% increment, in which the plant is used most intensively, gave the best outdoor thermal comfort. It also reduced the potential air temperature by 0.1 ℃ at the minimum, improving outdoor thermal comfort. As a result, it has been seen in this study that outdoor thermal comfort can be positively affected in spatial planning in the analysis of landscape design scenarios prepared by considering natural data.
