The Influence of Green Roofs on a Humanitarian Balance of the Biotechnosphere

Abstract

Greening roofs of existing buildings in urban areas with high build-up density is a reasonable way to mitigate the human impact on the biosphere in the absence of free space for landscaping. According to the results of statistical analysis for the Moscow city from 1999 till 2011 16 thousand hectares roof greening can reduce the number of patients with malignant neoplasms by 3.5%, that means green roofs have a potential to improve the urban population health, to increase the life expectancy and working capacity of the population. The absence of standards, regulates green roofs setting up in a particular place, leads to the impossibility of their distribution in megacities. Confirmation of the necessity and feasibility of green roofs installing can lead to the creating of regulatory documents obliging designers to use green roofs on new and reconstructed buildings.
