Energy-intensive building

This project is located on the south side of library information building in the Shandong Jianzhu University campus, adjacent to the eastern slope of the Snow Mountain. The total construction area is 9696.30 ㎡. The project is a multi-storey public building, the structure of which is steel frame.

The green land which is open to the public is made up of trees, shrubs and grass. The greening rate of this project is 40.10%. U-value of the building envelope is 10% higher than the current national standard. GSHP system will meet the cooling and heating need of the project by taking full use of the geothermal energy which is one type of the renewables. In addition, the project uses energy-efficient lamps to ensure that the main function rooms’ LDP is lower.

This project is the first passive and ultra-low energy green building with fabricated steel structure in China, which combines the dual advantages of passive buildings and fabricated buildings. The advantages include improving the indoor comfort, enhancing staff work efficiency, cleaning indoor air, saving energy, speeding up construction and improving construction precision, reducing construction waste and so on.

Owner approach of sustainability

The target of this project is to build a passive and ultra-low energy green building. Passive design methods minimized the heating and cooling demand. And renewable energy system provided heating and cooling need. And high efficiency fresh air system with heat recovery was used. Compared to the previous construction project, this project has made full use of passive technologies including the reasonable building size, reasonable building orientation and window-wall ratio, reasonable envelope design by using performance optimization design and node design. This project also strictly followed the key points of thermal bridge break design and air tightness. The energy saving rate was 81.05%.
Due to the project was assembled by steel structure system, many difficulties was met in the air tightness and thermal bridge break design. A lot of domestic initiative measures were taken during the design and implementation of this project including assembled steel structure building air tightness measures, embedded window installation form and scaffold pull joint hole airtight insulation treatment measures.
This project is the first passive ultra-low energy building with fabricated steel structure in China, the successful design and construction of which broadens the field and category of the passive ultra-low energy building. Based on actual conditions, bold research and innovation were carried. It is a major breakthrough about passive ultra-low energy buildings. The successful achievement of this project will provide many valuable experiences for other passive ultra-low energy buildings with fabricated structure.

Architectural description

The project is located on the university campus and all the landscape are open. According to the landscape design drawings of the project, the overall greening land area is 7826.35㎡and the greening land area of the declaration scope is 2581.53 ㎡. Shandong Jianzhu University is one of the green campus classics and had been selected into the United Nations Environment Programme green campus classic cases in June 2014.

If you had to do it again?

This project is overall fabricated with steel frame and precast autoclaved aerated concrete wall.
The basic passive house principles are followed in this project which include using high insulation envelope system, air tightness and thermal bridge break treatment methods and high efficiency fresh air system. Compared with other cast-in-place passive buildings, there are many challenges to solve the key issues of passive buildings through fabricated methods. The challenges include the air leakage treatment between precast outer wall board, insulation and air tight treatment of scaffold pull joint hole, the connection of the passive external window and the main structure, insulation and air tight treatment of steel column through wall and so on. There are not similar reference cases. Therefore, the construction of the project is very difficult.
To solve these technical challenges, with the leadership of the company's leading experts, the design and construction teams gave full play to their abilities to innovate and raised various professional programs including airtight strengthening measures of precast wall , setting 5cm thick insulation layer between the overhanging autoclaved aerated concrete and the floor, filling scaffold pull joint hole by using post-grouting after filling insulation material into the hole, embedded installing the exterior windows, thermal bridge break and airtight treatment of the steel beam column through the wall. To ensure the reliability of the technologies above, field tests were carried before the implementation of each special program.

Smart Building

    BMS (building management system) monitors the cold and heat source system and fresh air system. To achieve energy saving and comfortable office environment, indoor environment parameter is controlled by setting temperature and humidity sensors and air quality sensors. A special energy management platform is also set to collect energy consumption and classify monitoring data.

Urban environment

The project is located on the new campus of Shandong Jianzhu University. The campus is equipped with commercial services, sports and other places of service. The campus has public transport vehicles No. 317 and K161, which make people easy to travel. The new campus of Shandong Jianzhu University is located in No. 1000, Fengming Road, Lixia District and had been selected into the United Nations Environment Programme green campus classic case in June 2014.
