Project Net-Zero Energy Residential Test Facility - a house built on the site of the National Institute of Standards and Technology in Washington, DC. Scientists and researchers simulated in this lovely house lives a family of four. As a result, for the year the house nageneriroval 13,577 kWh of energy, which is 491 kWh more than originally planned result.
What are the characteristics of the house itself? It is 252 square meters, two floors. The design is nothing unusual - the house as a house. However, the whole area of the roof integrated solar panel. These panels are able to create a surplus of energy to survive the bad weather during the winter. Within 38 days of the 32 panels were covered with snow.
Energy consumption has been calculated as if the ordinary American family of four lives in the house, family members go in the shower, charge mobile phones and laptops, watching TV and so on. One of the important components in the construction of houses were volatile materials and layout: virtually eliminated unwanted air infiltration, while the level of insulation in the walls and the roof was twice that reduces the need for heating energy facilities. Also the house has a geothermal system for heating and cooling control.
The use of such technology in the construction of the house will cost 162 thousand dollars. In the US, the savings on electricity will be 4373 dollars a year. The experiment will continue to reduce the difference between the starting investment and savings. In favor of the preservation of money, of course.
