Buildings are the largest consumers of energy and producers of greenhouse gases in both developed and developing countries. According to incomplete statistics in Russia, Belarus and China, energy consumption in buildings alone accounts for 50 % of CO2 emissions. Therefore, there is an urgent need for changes in various areas of the building industry: energy efficiency, emission ...
