DOUBLE SKIN FACADE AND HYBRID VENTILATION OF THE ING HOUSE AMSTERDAM (ING BANK HQ)

摘要

The ING-HQ is characterised by a full transparent 2~(nd) skin facade. This transparency in combination with high indoor temperature requirements and the wish for low energy consumption was an interesting design challenge. The cavity between inner and outer facades can be ventilated in a controlled way using glass vents to: either discard excess heat or for hybrid ventilation. Interaction between active fapade and climate system results in an intelligent building. The big amount of glass was only acceptable in case of very low solar energy transmittance (g-value). TNO Building and Construction Research (Delft, The Netherlands) did research to check our prognosis. The "Advanced Window Information System", was used in combination with the CFD code WISH-3D. Validation of the CFD-model for this specific situation was done by laboratory measurements in a full-scale model. The g-value measured in the laboratory proved to be 0,07. After corrections a practical value of 0,08-0,11 was derived.
