Özet:

The increasing urban heat impact has led to more cooling in the summer in hot climate areas, while the cold climate area has increased energy consumption with more heat demand in the winter. In recent years, many studies have been conducted to provide energy savings, to produce solutions to reduce air pollution, to offer recommendations to reduce heating and cooling costs. The excess of green spaces in cities will reduce the reflection as well to reduce the heat island impact. Study often emphasizes the cooling effects of trees. However, the contribution of trees to the warming of the environment for cold climate areas should also be examined. This research was carried out in a site garden located in the city of Erzurum, where high numbers and cold climate conditions dominate, a new settlement area located in Yıldızkent. This site consists of 16 villas. In this area, on the first floor of a house with a plant cover in the surrounding area, 2 meteorological data measurement devices are placed on the south and north fronts. In December 2017, 24-hour microclimate data from the research field was recorded, and the ENVI-met software program was used for the scenarios prepared with average values. In these scenarios, the impact of the different distances of the building to the trees on thermal comfort has been studied. The distances; close to the building, determined as 2m and 4m, which scenario was analyzed as comfortable. According to the results of the analysis, when the distance between the trees and the building is 2m, the temperature of the environment is 9.2 °C warmer than the current state. The estimated average voting (PMV) analysis of the data has created maps for the current situation and alternative scenarios that are felt by people. As a result, the condition of thermal comfort and no thermal stress is the scenarios in which plants are planted in the building at 2m and 4m intervals, and the PMV value of 0.2-0.3 °C is determined.
