This research is aimed to study the significant number of negative environmental consequences are due to the active development of cities and agglomerations. The technologies of green buildings are constantly being improved with the aim of reducing the overall influence of development on the environment and human health. Today, one of the most important trends of eco-development is to develop the innovations in the field of green building structures. Green modular roofing structures contribute to solving the problems of ecodevelopment in the construction of smart cities and smart buildings for sustainable development.

The question of a healthy way of life of students in the conditions of quarantine restrictions is considered. The urgency of scientific research is caused by the sharp deterioration of the physical and mental condition of students due to the introduction of quarantine in the country caused by the COVID-19 pandemic, and in higher education institutions of distance learning. A necessary main prerequisite for maintaining health in quarantine is a healthy lifestyle, as a system of conditions that contribute to the strengthening and preservation of health. The purpose of the work is to identify areas for ensuring a healthy lifestyle of students during quarantine in the educational process of physical education. Research methods: theoretical analysis, systematization, comparison, generalization of literature data. According to the results of scientific research, the important and unique importance of physical education in the process of ensuring a healthy lifestyle of students has been proved. The directions of ensuring a healthy lifestyle of students during quarantine in the educational process of physical education are systematized: formation of students 'stable motivations for a healthy lifestyle application of all possible technologies in classroom and extracurricular physical education classes to educate students' needs and ability to maintain and improve their health. I; to provide students with a wide range of knowledge, on the basis of which the worldview of a healthy lifestyle should be formed; acquaintance of students with alternative methods of usual physical activity, for counteraction to negative consequences of quarantine and social isolation; development of programs and technological models of forming a healthy lifestyle by means of physical culture; development of methodical recommendations on physical education on the basis of innovative methods adapted for use at home during quarantine, in the situation of impossibility to use sports halls of educational institutions, sports clubs and playgrounds. The practical implementation of the findings is aimed at radical changes that will affect the development of physical education to ensure the health of students.

The features of the repair and construction work during the overhaul of buildings are reflected in the development of organizational and technological design documents, which include calendar plans. Organizational and technological models represent the basis for the development and calculation of calendar plans, as well as for determining resource requirements. They for prevention works, the order of their implementation, the nature of the relationship between individual works, reflecting the specifics of the selected technology for the production of work and the features of the simulated object. The scheduling of overhaul works is carried out on the basis of the developed methodology, which allows obtaining rational organizational and technological solutions with a low level of certainty of the initial information. To evaluate the final set of alternative options for calendar plans and choose the best option in accordance with the described methodology, it is recommended to use quasi metric methods. This allows us to lay the foundation for the rhythmic and coordinated work of all units involved in overhaul at the stage of scheduling, as well as to keep track of the possibility of ensuring timely completion of the planned work.

The purpose of the article is to review the theoretical foundations and practical examples of investor assessment with an integrated approach to the development of urban infrastructure. The article analyzes the conditions for reducing the investment costs of projects. For this purpose, methods of clarifying the conceptual apparatus, classification, systematization and an integrated approach are used. The significance of an investment project depends on its positive influence on at least one of the external or internal markets: material and financial products, services and labor, on the social environment and the environment. Examples are provided of the impact on urban planning and the ecology of the urban landscape of investment projects in the field of tourism in recent years, implemented at the expense of the Federal Target Program “Development of domestic and inbound tourism in the Russia for 2011-2018.” in Sarapul, Barnaul and Cherepovets. The authors conclude that in the examples cited there is a relationship between the risk tolerance of the project and the complexity of the approach to its implementation, and as a result, the amount of investment. Large projects are designed not only to solve specific problems of the investor, regions, economy, state and society, but also ensure the profitability of the state budget at various levels, create new jobs, ensure GDP growth in the country and investment in various sectors, create conditions for the development of the country’s regions. The narrowly focused investment projects are fraught with great risks for the investor due to the selectivity and limited scope of the manifestation of effects.
