本研究调查了塞萨洛尼基城区形态特征的不同干预情景对小气候参数的影响，如典型夏日的地表、空气和平均辐射温度分布。拟议的干预方案包括用类似的凉爽材料完全更换混凝土路面和沥青街道，增加树木数量，以及上述策略的组合。小气候模拟采用三维非静力气候模式ENVI-MET v.4。分析表明，由于用具有更高反照率和发射率的冷材料取代传统涂层，表面温度显著降低，而气温的变化则不那么重要。然而，结合使用凉爽的材料和额外的植树可以通过遮荫和树叶的蒸散来降低气温。
The present study investigates the impact of different intervention scenarios regarding morphological characteristics of an urban district of Thessaloniki on microclimatic parameters such as surface, air and mean radiant temperature distribution during a typical summer day. The proposed intervention scenarios include the total replacement of concrete pavement and asphalt streets with similar cool materials, increase of the amount of trees and a combination of the above strategies. The three-dimensional non-hydrostatic climate model ENVI-met v.4 is used for the microclimate simulation. The analysis reveals a significant reduction of surface temperatures due to the replacement of conventional coatings with cool materials of higher albedo and emissivity, while changes in air temperature are of lower importance. However, the combined use of cool materials and additional tree planting can contribute to lower air temperatures through shading and leaves’ evapotranspiration.
