The subject being examined is the development of low-rise residential construction. The aim of the research is the development of investment activity methods in low-rise residential construction by means of public-private partnership projects. This article is focused on the method of low-rise construction investment activities namely the utilization of public-private partnership (PPP) principles in implementation of such projects. It also analyzes forms, models and mechanisms of public-private partnership project implementation existent in the building sector. The classification of Russia's regions according to the level of the building complex development is carried out and degree of the state participation in PPP projects according to the region's socio-economic development is studied. The impact degree of various factors on building sector is researched and a new scheme of cooperation in low-rise construction based on public-private partnership is suggested. Interpretation of received data is conducted using pictorial schemes, tables and formulae. Obtained results laid the foundation for reduction of construction costs and increase in affordability of low-rise accommodation for certain categories of residents within the framework of public-private partnership. Results of the research can be utilized in regional sector strategic planning.

Purpose. Thermal and economic parameters of power systems in low-rise buildings during their construction and operation. Methodology. Analysis and comparison of thermal and economic parameters of energy systems in low-rise buildings. Research findings. The construction of low-rise buildings instead of individual houses confirms saving of capital construction and power system costs as well as energy savings while in operation. Based on the developed methodology, the capital and operating costs for power systems of an individual residence and a section of blocked houses are calculated. The main indicators for both house options are summarized and the most optimal option is selected. Research applications. These recommendations can be applied in modern housing construction and serve as a basis for new investment and construction projects on low-rise buildings that meet the energy efficiency requirements. Conclusion. Calculations show a 7% heat loss reduction during the construction of blocked houses. The capital cost savings for the construction of the sectional blocked lowrise building amount to 180.574 rubles.

-The given paper presents the new method to assess the effectiveness of low-rise housing projects based on the public-private partnership principles. The basic indicators of low-rise housing project effectiveness were defined. The possible options for the mentioned projects implementation were considered. The algorithm was suggested to assess the effectiveness of low-rise housing project based on the publicprivate partnership principles.
