Wall insulation, reducing window area, sealing joints, eliminating unnecessary air exchange, and heat exchange of air before ventilation are all ways for passive buildings to maintain appropriate temperature.
First of all, we understand the local residents’ understanding and attitude towards passive architecture in the form of questionnaire.
It is understood that the Qingdao urban and Rural Development Commission issued the guidelines for energy efficiency design of passive low-energy buildings in Qingdao (hereinafter referred to as the guidelines) on March 20, 2017, which came into force on April 1, 2017.
In order to meet the requirements of passive housing, the construction cost will increase to a certain extent, so the house price will also increase to a certain extent.
By designing the questionnaire, we also popularize the advantages of passive architecture.
60.56% of people think that it accounts for about 5% of the purchase budget, which is more acceptable.
The maintenance of constant temperature in four seasons is mainly realized through the thermal insulation layer and tightness of the house.
According to the survey report, only 14.09% of people have a certain understanding of passive buildings, 60.56% think that building energy conservation is very important, and people still attach great importance to building energy conservation.
It is said that in this stone shaped house, without air conditioning and heating, the indoor temperature can always be maintained at about 20 degrees Celsius, whether it is snowing outdoors or the sun is in the sky.
Due to the epidemic situation, we have given up the idea of visiting Siemens innovation center.
Compared with traditional buildings, the cost of passive buildings is indeed higher.
The reconstructed buildings and buildings such as hospitals, shopping malls and industrial plants can be implemented with reference.
56.34% of people think that passive buildings are attractive to them, and the main characteristics of passive buildings are constant temperature and low energy consumption.
The advantages of the fresh air system used in passive buildings are to replace indoor and outdoor air in time, purify the input air, and maintain appropriate temperature and humidity.
When the right time comes, we will conduct a field visit to Qingdao Siemens innovation center.
Through field investigation and consulting relevant materials, we found that Qingdao Siemens innovation center was once called the passive housing technology experience center of Sino German ecological park.
When investigating whether people know the average incremental cost of passive buildings, only 14.08% know.
This building is shaped like a huge stone on the top of Laoshan Mountain, with a special sense of streamline and rhythm.
It is currently the largest passive housing project in Asia.
By letting people know that passive buildings can obtain long-term and comfortable experience and service life at a higher cost, and weighing the advantages and disadvantages, people will also make the choice that is most beneficial to themselves.
The guidelines are applicable to the energy-saving design of new and expanded passive low-energy civil buildings such as residence, office, hotel, school, kindergarten and nursing home in Qingdao.
Like solidified music, it emits charming rhythm and rhythm and attracts people’s attention.

The thermal insulation layer of the passive house is made of rock wool, with a thickness of 25cm, which is more than twice the thickness of the thermal insulation layer of ordinary buildings.
Further understand and understand passive architecture, and contribute to the innovation and promotion of passive architecture and the development of green architecture in China.
As a passive building demonstration project in Qingdao, it is built by Sino German ecological park in cooperation with Germany Rongen architecture firm, Germany passive Housing Research Institute and China Academy of Building Sciences.
In order to further explore the development and popularization of passive buildings, members of the social practice team of “paying attention to passive buildings and bringing green energy conservation into life” of the school of civil engineering of Shandong University of architecture went to Huangdao District of Qingdao on January 29 to carry out field research and practice.
However, it is not only the streamline of the building that attracts more people’s attention.
