The article presents the development strategy of the energy supply system for National Research University “Moscow Power Engineering Institute” (MPEI) buildings based on green building. The designing mathematical model of one of MPEI academic buildings connected with the Scientific and technical library of the University has been created in Passive House Planning Package and designPH software. The parameters of the building energy supply system with the lowest energy consumption are presented.

The spread of the dangerous Covid-19 infection caused by the SARS-CoV-2 coronavirus since the end of 2019 has become a big challenge for both the world and Russian society. Thus, on January 30, 2020, the world health organization recognized the spread of a new infection as a public health emergency of international significance. On March 11, 2020, the same organization stated that the outbreak had become a pandemic. Currently, the role of social and environmental factors (which determine the spread of many environmentally-related diseases) in the spread of coronavirus infection in the population is not fully understood. The spread of Covid-19 infection in Russia can be divided into 3 stages. Stage 1 (31.01.2020-01.04.2020) - primary distribution. At this stage, the infection occurred mainly of Russian citizens visiting other countries. Stage 2 (1.04.2020-12.05.2020) - active distribution within the country. By the end of this stage, the maximum spread of infection is recorded. Stage 3 (12.05.2020-present) - gradual decline in the appearance of new cases of coronavirus infection. To assess the specific contribution of social and environmental conditions to the spread of coronavirus infection, data from the Federal information Fund for social and hygienic monitoring of the Federal center for hygiene and epidemiology of Rospotrebnadzor on indicators of financial security of citizens, quality of health care and sanitary conditions were analyzed. Studies have shown that at the first stages, a significant contribution to the spread of infection is made by the financial security of the population. The specific contribution of the quality of medical care, which is widely differentiated within the regions of Russia, affects only the third stage of the spread of coronavirus infection. Environmental and hygiene indicators make a weak contribution to the spread of Covid-19 at all three stages of the epidemic.

The article examines three different kinds of mathematical model of nearly zero energy building. The first model enables to optimize the structure and the definition of key parameters of energy efficient building. The second model is necessary for passive house designing with renewable energy sources. The third model should be used for monitoring and control of energy supply system of nearly zero energy building through year every hour of winter and summer.
