Buildings And Efficiency
The desire to minimize the energy consumption for heating buildings and reduce the negative impact on the environment led to the development of so-called "Passive" houses. To achieve unprecedented cost of these buildings have helped a number of factors. Firstly, the introduction of energy-efficient heating and ventilation systems. icult to be quoted properly. Secondly, application of modern architecture and high thermal performance building envelope (walls, roofs, windows). A related site: Philadelphia Condos mentions similar findings. Heating "passive" houses takes no more than 15 kWh per square meter. m per year. It is 10 times smaller than conventional indicators.
However, the construction of energy efficient homes and stands on a 5-10% more expensive than an ordinary house construction. Particularly active construction of "passive" buildings is carried out in Germany, Denmark, Norway and Sweden, where climatic conditions are comparable with those in central Russia. Total in Europe recent years, built a few thousand such objects. And this is only the beginning! In December 2009 the European Union adopted the Directive in building energy performance (Energy Performance of ). According to this document, by 2020 all new homes will have ultra-low power consumption (not bolee30 kWh per square meter. m per year). Significant changes have occurred in the psychology of the Europeans.
Two generations have grown up citizens of a united Europe, for which conservation all kinds of resources (including water, electricity, heat) is part of everyday life. Population saves money and at the same time making a contribution to the common cause of reducing energy consumption. The average Europeans like to have an image of a man who cares not only about their own budget, but also about the environment.
