Microclimatic Effects of Green Facades in Urban Environment
The processes of the last decades’ – such as climate change, growth of cities, and the decreasing of urban green spaces – increase the risk of overheating during the summer. The significance of vegetable shading is, that through evapotranspiration it can minimise the risk of overheating and the negative effects of urban heat island. Although there are some previous data about the effect of vegetation, there are still questions in the scope of the microclimatic and energetic effect of vegetation planted in front of the façades. The effectiveness of urban vegetation varies on a large scale depending on environmental conditions. For example the effect of street tree lines on wind speed changes in relation with the angle of the axis of the street and the prevailing wind direction. The mentioned dilemma is a major issue of planning urban ventilation. That is why more precise calculations are needed to be able to use urban vegetation properly and most effectively. Scientific research should provide a background for quantifying the effect of urban vegetation so that designers could be helped to use more confidentially the vegetation as an important “building element” in the build-up environment. In order to facilitate vegetable shading the paper presents an attempt for the quantitative evaluation of green facades.
