High comfort: the indoor temperature is 20-26 degrees, and the surface temperature of all sides of the enclosed room is not lower than the indoor temperature by 3 degrees; Air relative humidity 40-60%; Indoor air velocity is less than 0.2m/s; The noise is less than 35 dB; The air exchange capacity is 20-30 cubic meters H person; Indoor carbon dioxide content is less than 1000ppm; Domestic hot water demand 60 degrees; 25L / person / day; There shall be no condensed water and mildew on the indoor surface.
Therefore, it can greatly improve people’s quality of life and is particularly beneficial to people’s physical and mental health.
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.
Construction time of passive low-energy buildings for self built houses of rural houses in Beijing: September 16-december 31, 2021; Project content: foundation, main body, thermal insulation, doors and windows, fresh air system and interior decoration; General contractor: Beijing Sunshine Shida Construction Technology Co., Ltd; Technical director: giant expert of China Building Energy Conservation Association; Construction Supervision: Phi certified constructor of German passive Housing Research Institute; Parts and components: doors and windows, fresh air system, air tight tape, thermal insulation materials and other parts that have obtained the recent certification certificate of phi or relevant national testing institutions; Project quality acceptance: Phi constructor and giant experts in the passive housing industry; Service life of the building: 70 years.
The room is extremely clean, and the cycle and degree of cleaning will be greatly reduced.
Architectural design description passive house (called near zero energy consumption building or passive ultra-low energy consumption building in China) is a kind of passive technology that only uses efficient thermal insulation, such as peripheral protection structure, superheat energy, heat gain inside the building and fresh air equipment with heat recovery factor of more than 75%, instead of active heating equipment The building can meet the indoor comfortable temperature range required by the specification throughout the year.
Architectural Design Description 2.
1、 Construction time of self built passive houses for rural houses in Beijing: 2021.10.12-11.22, 2022.03.15-4.25; Project content: foundation, main body, thermal insulation, doors and windows, fresh air system and interior decoration; General contractor: Beijing Sunshine Shida Construction Technology Co., Ltd; Technical director: giant expert in passive housing; Construction Supervision: Phi certified constructor of German passive Housing Research Institute; Parts and components: doors and windows, fresh air system, air tight tape, thermal insulation materials and other parts that have obtained the recent certification certificate of phi or relevant national testing institutions; Project quality acceptance: Phi constructor and giant experts in the passive housing industry; Service life of the building: 70 years.
The air tightness of the building shall be less than 0.6 times (the air exchange rate shall be less than 0.6 times per hour under the pressure difference of 50pA indoor and outdoor).
Excellent air tightness.

Benefits of passive housing: 1.
Energy saving of more than 92%: the annual living electricity and heating cost of 100 square meters of passive housing is about 1781.2-2671.80 (the first grade civil electricity price in Beijing is 0.488; the annual heating cost of ordinary housing is 30.00/m2).
