The air tightness of the building is less than 0.6 times (the air exchange rate is less than 0.6 times per hour under the indoor and outdoor 50pA pressure difference).
2.
H person; the indoor carbon dioxide content is less than 1000ppm; and the raw air The demand for live hot water is 60 ℃; 25L / person / day; Condensation water and mildew shall not appear on the indoor surface.
Excellent air tightness.
Good performance of passive house Location: 1 More than 92% energy saving: the annual living electricity and heating cost of 100 square meters of passive houses is about 1781.2-2671.80 (the first grade civil electricity price in Beijing is 0.488; the annual heating cost of ordinary houses is 30.00/m2).
The indoor is extremely clean, and the cleaning cycle and degree will be greatly reduced..

Because the fresh air system continuously delivers filtered fresh air to the room, the amount of oxygen is extremely sufficient and the turbid gas is eliminated, it can greatly improve people’s quality of life, is particularly beneficial to people’s physical and mental health, and is very suitable for the living of the elderly, children and pregnant women; The green plants and flowers in the passive room grow vigorously, and the fish jump around happily; It has great improvement for patients with chronic pharyngitis and rhinitis.
Architectural design description II.
Architectural Design Description: Passive House (called near zero energy consumption building or passive ultra-low energy consumption building in China) is a kind of building that only uses passive technologies such as efficient thermal insulation peripheral protection structure, too much heat energy and building internal heat gain, and fresh air equipment with heat recovery factor of more than 75%, instead of active heating equipment, so as to realize that the building can meet the indoor comfortable temperature range required by the specification throughout the year.
