Qingdao Tongda Sino-German Friendship School Passive House Project

Qingdao Tongda Sino-German Friendship School Passive House Project

The city of Qingdao has an averagely mild climate, with four distinct seasons, affected by recurring monsoons and lies in a transition belt between a subtropical humid climate and a temperate continental (humid) climate. Winters can be long and dry, cold and windy so that reducing the heating energy consumption is of major concern; during the summer, temperature differences between day and night are large: with hot daytime and chilly nights. Here, applying shading  measures are crucial to be considered accordingly. At the primary and secondary entrances of the southwest facade of the school building, a concave design is used to provide shade to the building. In addition, fixed sunshade louvers are being implemented in front of the large glass windows above the entrance area. The facade insulation layer is beveled under the premise of ensuring the effective thickness to form a slanted window gang, enriching the facade styling, thus offering additional shading effects. The southwest façade is provided with movable shade shutters, too.


Qingdao has very abundant solar energy resources. Therefore, solar photovoltaic panels are installed on the roof of the dormitory building. Doing so, the overall heat loss, i.e. heating and cooling energy consumption of the building, are calculated by combining the parameters of the building ventilation and heating and cooling systems, aiming at to control and ultimately reduce the building energy consumption. In order to avoid problems due to the lack of air ventilation in public toilets and shower rooms, as well as to avoid the humidity in summer to affect the fresh air quality in these public spaces, dedicated fan systems are being installed. The entire building adopts a passive external wall thermal insulation system, certified passive doors and windows, a continuous uninterrupted airtight layer, a fresh air system with a total heat recovery efficiency of up to 75%, a non-thermal bridge node design, and an energy-efficient integrated hot water heating and cooling units.
