Abstract
Humanity during its existence seriously harms the world around it. One of the negative consequences of thoughtless human activity is the global warming. There are many physical reasons for this, one of them is uncontrolled emissions of harmful gases into the atmosphere, which entail a greenhouse effect. It is investigated that a large contribution to the heat emissions into the atmosphere is made by construction activity. In this article, we propose to use green walls as an effective solution to increase the energy efficiency of buildings by reducing heat emissions from them, which, accordingly, will improve the quality of the atmosphere. We analyzed different green wall systems, their characteristics and we have measured the internal and external temperatures. The result of the experiment showed that the best thermal performance was observed in the green wall module with sandy substrate with vegetation. The use of this system allows to reduce temperature by several degrees, depending on the type of vegetation. The green wall module demonstrated the highest thermal performance. This system can lower temperatures by several degrees, depending on the plant species used. For optimal thermal effectiveness, the substrate should retain enough moisture to support healthy plant growth, but not so much that it leads to consistently high thermal conductivity from oversaturation. Green walls are environmental elements of urban infrastructure that help inhabited cities reduce, in particular, the effects of their warming due to the climate change.
