Owner approach of sustainability

As the first passive ultra-low-energy building project in the Central Plains, the “Fivewin Science and Technology Museum” is designed, constructed and monitored in strict accordance with the characteristics of passive ultra-low-energy buildings. Compared with traditional construction projects, the construction indicators refer to domestic "Passive ultra-low energy green building technology guidelines" and Germany passive house PHPP design method, comprehensive optimization, to achieve a good thermal performance of the external insulation structure, high-performance door and window components, fresh air with full heat recovery, high COP soil source and air source heat pump unit. Realizing healthy, comfortable and energy-saving indoor living environment which plays an important role in promoting the innovative and healthy development of modern buildings.

The project is designed and constructed in strict accordance with the German passive house standard and domestic relevant energy-saving standards, from (1) high standard external wall thermal insulation system; (2) high performance doors and windows; (3) good air tightness; (4) near no thermal bridge design; (5) efficient fresh air heat recovery system; (6) comprehensive application of natural ventilation and natural lighting; (7) intelligent control and management of equipment and lighting; (8) utilization of renewable energy: a. ground source heat pump; b. solar photovoltaic technology; c. solar thermal technology, controlling various performance parameters, continuously optimize the node design, maximize the proximity to the idealized model, and finally make the building wall heat transfer coefficient 0.22 w/(m2.k), roof heat transfer coefficient is 0.20w/(m2.k), glass heat transfer coefficient is 0.61w/(m2.k), overall air tightness N50=0.17h-1<0.6h- 1. The fresh air heat recovery efficiency is 77.3%>75%. The energy consumption index meets the German passive house standard and has been certified by the Germany Passive House Institute.

Architectural description

First, the project uses high-efficiency fresh air heat recovery system, the sensible heat recovery efficiency is greater than 75%, and the total heat recovery efficiency is greater than 70%, effectively reducing the fresh air load. The outdoor fresh air passes through the plate type coarse filtration and medium efficiency filtration to filter out dust, PM2.5 particles and harmful substances, and exchanges heat through the plate-fin heat recovery section, then the temperature and humidity treatment from the cold section, and finally sent indoors. The unit not only saves energy but also delivers high-quality fresh air to the interior to meet people’s needs.

Secondly, the project has designed near no thermal bridge design for the building envelope, avoiding the damage caused by the heat bridge to the building envelope, such as condensation and mildew, effectively improving the comfort of the building.

Third, the ground source heat pump is used for energy conversion. The ground source heat pump is a clean renewable energy source, which greatly reduces the pollution to the environment. According to statistics, the use of ground source heat pump technology can save an average of 30% to 40% of air conditioning operating costs.

Fourth, the project adopts the building photovoltaic integrated system, which ingeniously integrates the photovoltaic film with the landscape gate and the landscape rain shelter slope roof. The translucent film not only plays the role of sunshade and rain, but also provides cleaning renewable energy for the science and technology museum. It is the perfect combination of new energy and architectural landscape. Photovoltaic power generation effectively saved the traditional energy sources for the Science and Technology Museum.

Fifth, the intelligent control system can intelligently control indoor lighting, air conditioning, fresh air, sunshade and other equipment.

Building users opinion

In terms of thermal comfort, the thermal stability of the enclosure structure of this project is significantly better than that of ordinary houses, creating an indoor environment with warm winter and cool summer, winter temperature ≥20℃, summer temperature ≤26℃, relative humidity 30%-60%, which is good for the health of residents.
In terms of air quality, the good airtightness of the building makes it impossible for outdoor polluted air to enter the room directly. At the same time, the outdoor fresh air is sent into the room through the coarse and medium-efficiency filtration of the fresh air unit, ensuring good indoor air quality, and the user is more assured and comfortable.

In terms of light environment, the building window and wall ratio is relatively large, which ensures sufficient brightness and good light quality in the room. At the same time, external shading is set to avoid glare.
In terms of acoustic environment, the building has the characteristics of sound absorption and sound insulation, and is free from traffic noise and neighbor noise, giving users a quiet and private environment.
