Precast | breathing house: Science and technology model from “city of the future”
The reason why it is special is that its birth has promoted the construction of a green and livable new urban area in xiong’an new area and created a national demonstration project for the application of green ultra-low energy consumption buildings.
These two houses can ‘breathe’ so that you can experience the feeling of four seasons like spring in a cold night.” Project leader Xiao Kelin introduced.
As the sub exhibition hall of the “xiong’an spring” calligraphy and painting exhibition, a steady stream of xiong’an citizens come to visit every day.
Every “breath” of the house comes from the control of the fresh air system.
It is estimated that ultra-low energy consumption passive houses are 70% to 90% more energy-efficient than conventional buildings.
Through the filtration, impurity removal and humidification of the air, the pure and humid fresh air is continuously sent into the room, and then the exhaled dirty air is discharged.” Introduced by he Haizhong, Secretary of the Party branch of the project.
“The high-efficiency recovery fresh air system is similar to people’s’ lungs’.
The ultra-low energy consumption passive house adheres to the “five constant” concept of constant temperature, humidity, oxygen, cleanliness and stillness, and the construction standard of ultra-low energy consumption and low emission.
The external wall thermal insulation material of ordinary buildings is generally 10cm thick, while this kind of building adopts high-performance enclosure wallboard, including 50mm air thermal insulation layer and 180mm thick class a rock wool board.
This is a breathing house, assembled integrated house, passive ultra-low energy consumption technology application, coupled with the beautiful scenery of “paradise”, it is simply a natural oxygen bar.
Even if the outdoor noise is noisy, it can make people “don’t hear things outside the window”.
“Not only green energy conservation, but also the application of passive ultra-low energy consumption technology.

The ultra-low energy consumption passive house is also vividly known as the “green magic box” because of its unique green energy-saving design.
There is no need to install heating, refrigeration, humidification, sound insulation and other facilities separately.
Staying in such a “breathing” house is like living in a “thermos”.
If the wall is compared to a “thermos bottle”, then the doors and windows are the “bottle stopper” of the house.
Through the design optimization of enclosure structure, the building has high-quality thermal insulation performance, so as to achieve the purpose of energy conservation and comfort.
Compared with the traditional heating and air conditioning that adjust the cold and hot humidity, the energy consumption of the fresh air system is relatively reduced, but the function is 4 to 5 times higher.
“The house has the characteristics of warm in winter and cool in summer, moisture resistance and strong air permeability.
According to the plan, xiong’an new area will vigorously “promote ultra-low energy consumption buildings” and build a green and livable new urban area in the future.
It is not only “thick”, but also “strict”.
The high-performance passive doors and windows with level 6 water tightness and level 8 air tightness and aluminum clad wood three-layer double hollow Low-E glass keep the indoor sound in the comfortable volume range of 30 ~ 40 dB.
If indoor hygiene can be maintained, there will be no mosquitoes.” At present, the planning and construction of xiong’an new area has entered the stage of full implementation.
It only takes 20 days to build such a house, which effectively shortens the construction period compared with traditional building construction.” Xiao Kelin said.
It is located opposite gate 5 in the west of xiong’an citizen service center.
Aunt Zhang, who lives near the citizen service center, said: “it’s hard to believe that there will be such a house without heating or air conditioning, but it can still keep the indoor spring all the year round.
There is a special building in the green space between P2 and P3 parking lots – ultra-low energy consumption passive house, with a construction area of 161.2 square meters, which is undertaken by company 9, It will be used as the sub exhibition hall of “xiong’an spring” calligraphy and painting exhibition.
In the early stage of construction, in order to fit the xiongan concept of “environmental protection, green and fast” with the design of passive housing, the project design team consulted a large number of relevant materials at home and abroad, and finally adopted the first domestic precast integrated housing combined with passive ultra-low energy consumption technology to truly realize the low pollution, low cost and low energy consumption of the building in all aspects.
