The building envelope is a key element of a building which affects its energy balance and the quality of the indoor climate (heat, sound, air and light comfort). It is exposed to the tem- perature differences between outer and inner spaces, through which the building directly loses heat, so its analysis is very important. Buildings lose about 21% of energy through exterior walls and about 51% through windows (Figure 1). Minimal energy consumption in buildings is in- fluenced by many parameters, which include:

Principi implementacije SVO (Cekié, 2019) The analysis of the characteristic features of the building is an architectural analysis of the build- ing itself, on which the installation of the VGS system is planned. This analysis is conducted independently and it defines the constructive and design paremeters, which directly influence the selection of the appropriate type model o the VGS system. It is exactly on the elements of this analysis that a further analysis of the planning structure is carried out. It can be said that, depending on the parameters defined by the analysis of the characteristic features of the building, further analyses and even the design of the VGS system are carried out. The design of the system is developed on the basis of the concept and conceptual design, which is the re- sult of previous architectural analyses. The de- sign defines in detail the choice of substructure, plant material, method of installation, as well as all other requirements that the system must sat- isfy in order to be successfully implemented. Ac- cording to the chosen system design, a planned maintenance system is performed as well as the cost-benefit analysis for the intended model at a specific location (Figure 4). The basic principle of VGS system implemen- tation is based on a detailed analysis of the location where VGS system implementation is planned. Primarily, urban analysis is used to define the narrower and broader locations and from which directly results the analysis of mi- croclimatic conditions. Microclimatic conditions are a very important element in planning the application o f a VGS system, since the certain types’ need for increased insolation along with the strong air flow can cause permanent damage to the system. That is why this analysis should be conducted mate inputs. according to the correct microcli-
