Deign House In Rusia

The First Active House in Russia is energy efficient and easy to operate. To reduce CO2 emissions and optimise energy performance, the building must be considered as a whole, not just the sum of its components.

The house exploits a variety of energy sources that are integrated in the overall design. Free energy from the sun is the primary energy source of the house. The features contributing towards a positive energy balance include a highly effective heat pump, thermal solar collectors for production of hot water and a PV solar cell system to generate electricity.
VELUX solar thermal collectors designed for installation in combination with roof windows exploit the heat of the sun while providing a visually appealing and technically optimal solution. VELUX solar collectors can generally provide up to 65% of the energy required to produce domestic hot water. The sun is the most powerful source of energy we have and we should make maximum use of it.

The orientation and design of the house make it possible to utilise daylight more actively. The windows should be considered as energy contributors. They are placed strategically to allow for solar heat gain and optimum natural ventilation. The energy requirement for basic lighting in large parts of the house is minimised by effective use of daylight.
A tightly-sealed construction is vital for achieving low energy consumption. The walls are highly insulated with multiple layers. Special highly compressed gypsum is added on the inside of the walls to add thermal mass to the light timber frame construction.
The results of an energy calculation performed by the Passive House Institute in Russia show that the specific consumption of energy for heating during the heating period is 38 kWh/m2/year.
