Ayrıca yeni yapılan parkların çoğundaişlevsellikten önce estetik değere sahip bitkisel materyallerin kullanıldığıgörülmektedir. Bu gözlemler sonucunda sert zeminlerin artmasınınkentlerimizdeki iklimi nasıl etkilediği merak konusudur.Çalışma alanı Erzurum Kalesi’ninbatısında yer alıp kentsel dönüşüm alanı kapsamında bulunmaktadır. Mevcuttaotopark olarak kullanılan ve ezilmiş toprak örtüsüne sahip alana; 5 farklısenaryo ile beraber sert zemin oranlarının değiştiği tasarımlar yapılmıştır.Yapılan tasarımlar ENVI-met programıyla değerlendirmeye alınmıştır. Butasarımlar kapsamında sert zemin oranı arttıkça iklim odaklı dış mekan termalkonforunun olumsuz yönde etkilendiği çalışma sonucunda tespit edilmiştir.Yapılan bu tespitler Predicted Mean Vote (PMV) standartlarına görebelirlenmiştir. Ayrıca çalışma sonucunda bitkilerin kullanım şekilleri veyerlerinin de önem kazandığı sonucuna varılmıştır. Çalışma alanında parkiçerisindeki dış mekan termal konforunu etkili bir şekilde arttıranparametreler; yeşil alanların artması, ağaçların kullanılması ve çalılarınağaçlarla birlikte kullanılması olarak belirlenmiştir.Sonuç olarak; tasarım yapılan parkalanı için yeşil alan kullanımı oranı azaldıkça, dış mekan termal konforunun“termal stressiz” aralığından “hafif sıcaklık stresli” ya da “sıcaklık stresli”aralığına geçiş yaptığı tespit edilmiştir.

In addition, in most of the new parks, it is seen thatplant materials with aesthetic value are used before functionality. As a resultof these observations, it is curious to see how the increase of hard surfacesaffected the climate in our cities.The studyarea is located in the west of Erzurum Castle and is within the scope of urbantransformation area. In the area with crushed land cover, which is used as acar parking area, designs with 5 different scenarios and hard floor rates werechanged.The designs were evaluated by ENVI-met program. Asthe hard floor ratio increases; climate-oriented outdoor thermal comfort wasaffected negatively in the study. These determinations were made according toPredicted Mean Vote (PMV) standards. In addition, it is observed that the useof plants and their places have gained importance. Factors that changepositively the outdoor thermal comfort of the space in the park; the increasein green areas, the use of trees and the use of trees with shrubs.As a result, as the ratio of greenspace usage for the designed parking area decreases; It has been determinedthat the thermal comfort of the outdoor thermal comfort shifts from the"Comfortable" range to the "Slight Heat Stress" or"Modereta Heat Stress" range.
