Evaluation of the effectiveness of ""green"" buildings is usually carried out by a third party using a rating system. The rating system STO NOSTROY 2.35.4–2011 assesses habitat sustainability according to 46 criteria, which are grouped into 10 categories, presented in Table 1. STO NOSTROY 2.35.4–2011. The article presents the methodology developed on the basis of the above-mentioned rating system, as well as the foreign LEED system, and the S-factor for the designed 16-storey residential building is calculated. The calculation for clarity is presented in the form of a diagram. Since the design we strive to get as close as possible to the highest grade of assessment, the most attention is paid to such concepts as energy saving and energy efficiency. Calculation of economic efficiency is possible on the basis of the resource-technological model by calculating the volume of waste during the overhaul and demolition of the designed building. This is a necessary task, since the construction of environmentally-friendly, sustainable buildings requires full consideration of the life cycle of the building, and accounting for the entire life cycle necessitates integrated design. The time spent at an early stage on the complex design of the building, taking into account the concept of sustainable development, is rather quickly compensated with the start of building operation, since it is known that the largest share of costs falls on the operational period of the building. So, as a result of calculating the S-factor, the building is assigned a certain grade of assessment. Raising the grade of an assessment of a building being erected will lead to an increase in its investment attractiveness. That is why it is important to perform a similar calculation at the design stage of the life cycle of the construction object, since in this case we have the opportunity to increase the value of the S-factor to the required.
