Analysis of the Sponge City in Relation to the Amount of Greenery

Nowadays, many cities are struggling with overheating, mainly because cities are growing, urban development is becoming denser and greenery is disappearing from cities. There are several ways in which we can improve the urban environment. However, not every city struggles with the same conditions and therefore the principles of urban design and mitigation are different. The simplest and oldest way to reduce temperature is to use green space and cool it down by shading, or even evaporation. In addition, greenery has other benefits such as improving air quality, visual effect and acoustic comfort. Around the world, various organisations are working on this area and cities are following their own legislation. Although the legislation is already in place around the world, each city needs a different approach to the regulations. An individual approach for the design and application of green spaces is important in urban planning. New technologies and approaches to green architecture can also be used for new developments. However, a different approach will be needed for buildings to be renovated. However, before policies can be developed, urban green space needs to be analysed, broken down and analysed. In this paper I will discuss the analysis of urban greenery in the city of Košice.
