UDD NetZero Building Base #1
Taicang, China
The three-storey office building designed by NEUBAU best.energy is located near Shanghai in the city of Taicang and has been recognised as the first premium passive house building in China. Individual and open-plan offices as well as meeting rooms are located on a total floor space of 2,050 m².
The prevailing warm and humid climate posed a particular challenge for the construction method. In order to achieve the Passive House Premium standard under these challenging conditions, careful planning was essential. Tailor-made solutions such as a specially designed lighting concept with presence and environment-dependent control, a reservation and access system to minimise standby consumption are just a few of the energy-efficient pieces of the puzzle in the overall concept.
Passive summer heat insulation and building tightness were important parameters in order to minimise energy requirements accordingly. A 151 kWp photovoltaic system guarantees sustainable energy for the existing requirements. The building uses concrete ceilings for cooling. Due to the high regional humidity, a humidity management system was implemented, which enables the separation of dehumidification and sensitive cooling. This prevents the formation of condensation.
