Environmental Aspects of the Housing Renovation Program in Moscow under Sharing and Circular Economy Conditions

Since 2017, a housing renovation program has been implemented in Moscow, which is a unique program aimed at settling and demolishing shabby low-rise housing stock and new construction on the vacated territory. The renovation program raises a fundamental issue of construction waste disposal. Many current technologies of building mass demolition imply dusting of adjacent territories, have low efficiency in transporting construction waste generated in this process and lead to environmental problems resulting from its disposal, so the rational use of construction waste becomes one of the environmental protection's main points. In this research, we address the question: how the principle Green Digital Technologies, reflected in the Moscow development concept Smart City, which is a part of the housing renovation program in Moscow, is currently implemented. Three implementation ways of this principle have been revealed: contraction of smart houses under the renovation program according to smart 1.0 standard; use of BIM-technologies in the program; use of smart demolition technology. It is proposed to consider the process of recycling construction waste after demolishing old houses under the renovation program according to the principles of sharing and circular economy to increase the program's environmental friendliness and reduce environmental risks for the Moscow population.
