Building of energy -efficient houses and buildings: dignity and trampling
The construction and operation of housing is one of the most energy -intensive areas of the economy. For example, the buildings and buildings of Great Britain use approximately 30% of the total energy of the state.
Practice shows that in order to change the current situation, great efforts are necessary on the part of the whole country, for a phased decrease in energy consumption in the housing and construction fields by mass construction of energy -efficient houses and the reconstruction of existing.
A perfect energy -efficient building is an almost closed system: gas is produced from sewer departments, sunny batteries are transmitted, water supply is transmitted, water supply is implemented using rain and groundwater.
The fundamental importance for energy -efficient buildings is low heat transfer of protective structures – windows and walls. Heat loss of an ordinary brick house-250-350 kW/h with a square meter of heated area per year. In energy -efficient buildings, this indicator is almost 20 times less – 15 kW/h with 1 square meter.
