ABSTRACT
In today’s energy science, specifically in its building power energy section, it is ascertained that in the rating of primary energy end users, modern construction and operational building technologies have steadily occupied the impressive second position, following industry (transport occupies the third position). These have a different share in the national energy balances, varying within 26%–39%. The existing data on the energy consumption in rapidly developing countries, like India and China, have outlined an upward tendency of energy share in the construction business. In developed countries like those in the EU, the United States, Japan, South Korea, Canada, and Australia, systematic and comprehensive activity has gotten underway with the reduction of the consumption of primary energy generated by fossil fuel resources and in a wider implementation of renewable energy sources. Economy of energy so far has been pursued in different ways-from governmental state regulations and subsidies to informal social and even personal efforts of the citizens in their roles as private investors in various energy-saving projects.
