Winter time

-20°C outside. The fresh air is introduced in the building through an underground duct [-1.80m below the natural terrain], preheating it because of the earth’s constant temperature throughout the year. It is introduced in the house at +8°C. Heating the fresh air from +8°C to +23°C requires less energy, than introducing the air directly from outside.
