Owner approach of sustainability
Passive House Technology Center in Sino-German Ecopark is a key project of China-Germany passive house cooperation which signed by Premier Li Keqiang and Prime Minister Merkel. the project’s design and passive ultra-low energy green building certification consultant are completed by China Academy of Building Research and the German ROA firm, which is the most Representative passive house project in China. It has been certified by PHI and China Passive Nearly zero Energy Building.
1) The project adopts the German passive house design concept, which can effectively improve the indoor environment quality and reduce energy consumption. It is the first public building in the cold climate zone to meet China's passive ultra-low energy green building standards;
2) The accumulated cooling and heat load of the air-conditioning and heating period and air tightness meet the German passive house standard, and the relative energy saving rate exceeds 85%;
3) In terms of architectural design, the project combines the terrain and geomorphology to reasonably set the building space and reduce the body shape coefficient. It is equipped with a natural lighting, ventilated atrium, with a self-shading structure, and implements the passive concept of “active firstly, passive optimizely”.
4) The whole process service is adopted without heat bridge, airtight fine design and design and construction. The air tightness test result of the project is N50≤0.45.
5) Uncontrolled power chilled beam and dual heat recovery new fan unit technology with independent control of temperature and humidity bring significant energy saving benefits and high indoor comfort standards.
6) The transmission and distribution system is optimized to the ultra-low resistance design, which greatly reduces the energy consumption of the pump.
Architectural description
As a passive green energy-saving building, this project strives to become a passive green building demonstration project in Qingdao. It draws on the natural forms such as ocean, river and pebbles in the planning and design concept, and adopts the design principle of building, indoor and landscape integration as energy-conservation services.
Architectural design
The pebble shape in harmony with surrounding environment and greening. The main lighting surface of the building faces the southeast facing green space, maximizing the illumination and landscape orientation;
At the same time, the building and the semi-subsidence square are facing southeast (Qingdao summer dominant wind direction), which is convenient for discharging of waste heat rapidly; the low-sloping sun in winter allows the building to make maximum use of sunlight while keep the northwest wind from the building and square.
Interior design
Adopting green design concept of low energy consumption;
The sunlight is introduced into the room from the skylight for sufficient illumination, and the room around the atrium can be lit through the high window;
The atrium is made of transparent glass slats for light transmission to save energy.
Landscape Design
The streamlined green landscape design not only improves the surrounding micro-environment of the building but also plays a good guiding role in the functional streamline. To create a “watching and being watched” interaction between architecture and landscape, nature and architecture are symbiotic, and the building is perfectly integrated into the environment;
Atrium landscape design integrates indoor part and outdoor part. The project introduces the greening into the room, which can adjust the indoor microclimate and reduce some energy consumption.
Building users opinion
Satisfaction survey was conducted for users working in the building: lighting environment satisfaction was 100%, air quality satisfaction was 95.24%, thermal environment satisfaction was 85.72%, acoustic environment satisfaction was 90.48%, and the calculated PMV value was calculated. -0.08, the PPD value is 5.14%. The main reason for dissatisfaction is that indoor temperature and humidity in summer are slightly uncomfortable while the overall satisfaction level is good.
