The Net-Zero Energy Residential Test Facility project is a home built at the National Institute of Standards and Technology in Washington, DC. Scientists and researchers simulated in this lovely house the life of a family of four. As a result, over the year the house generated 13,577 kWh of energy, which is 491 kWh more than the originally planned result.

What are the characteristics of the house itself? It is 252 square meters, two floors. There is nothing unusual in design - a house is like a house. However, solar panels are built into the roof over the entire area. These panels were able to create a surplus of energy in order to survive the bad weather during the winter. Within 38 days, all 32 panels were covered with snow.

The energy consumption was calculated in such a way as if an ordinary American family of four lives in the house, family members go to the shower, charge mobile phones and laptops, watch TV and so on. One of the important components in the construction of a non-volatile home was the materials and layout: unwanted air penetration was almost eliminated, while the insulation level in the walls and roof was two times higher, which reduced the energy needed for heating the premises. The house also has a geothermal system for controlling heating and cooling.

The use of such technologies in building a house will cost 162 thousand dollars. In the United States, energy savings of $ 4,373 per year. The experiment will continue in order to reduce the difference between the initial investment and savings. In favor of the safety of money, of course.
