Building Physics

Vanke Beijing CFD ©ArupVanke Beijing Green Building Park.
Phase one of a Government sponsored Innovation Park to demonstrate future best practice for China. The Visitor’s Centre building design targets ‘true operational zero carbon’ and BREEAM ‘Outstanding’ environmental assessment. Exploits advanced building physics passive design to reduce air-conditioning capacity by 75%. Energy demand matched to output of Combined Heat & Power unit fuelled by on-site recycled waste cooling oil.

Jersey Archive and Records Office, St Helier, Jersey, Channel Islands.Jersey Archive Centre ©Arup
New 1800 sq m building for the storage, exhibition, conservation, research and education activities of publicly held artefacts, documents and historical photographic material.  The building is a low energy, naturally ventilated passive design.  It included 700 sq m of archive designed to achieve BS5454 ±5% relative humidity close-control using only passive moisture and thermal abilities of the building fabric, coupled with natural ventilation. Responsible for developing the concept of moisture control using passive building fabric characteristics and the analytical prediction techniques, the building design concept, detailed design and site implementation for integrated multidiscipline engineering and building physics design.

Deir Al-Surian Library & Archive, Wadi Al Natrun, Egypt.Deir Al-Surian Non-mechanical air-consitioning Twinn
A new 3 storey and basement library and archive building within the grounds of the Al-Surian Monastery seeking to provide a low capital and running cost, locally appropriate solution to the storage of and access to unique historic manuscripts. By harnessing features of the local climate together with careful choices of construction details and materials, the aim was to provide a completely passive approach without the need for any air conditioning, representing a contemporary interpretation of the successfully preservation over the previous many hundreds of years. Responsible for the concept design of building physics and mechanical systems.
