BedZED is a multi use complex in London designed to promote sustainable working and living lifestyles. The complex has proven the effectiveness of a holistic approach toward sustainable design over just adding on several green strategies. Asides from a complete approach toward sustainable living, BedZED incorporates insulation, triple-glazing, south facing glazed surfaces, and a passive-stack ventilation with heat recovery.


Other Case Studies:

Queens Building, De Montfort University

The environmental design strategies for the Queens Building in Leicester UK is to look to past sustainable solutions and using modern technology, update and refine those solutions. The building was designed to incorporate natural ventilation to mitigate internal heat gains. A combination of a stack effect and wind effect determined the shape and size of air intake and exhaust vents. In the summer the building is pre-cooled at night by allowing air movement through the building. 




CarPark in Heilbronn, Germany

The car park at Heilbronn utilizes natural ventilation and lighting to service the parking garage. The focus of this system is to maximize the materials. Reinforced concrete floors, steel I-beams, and a Douglas fir facade minimize the environmental impact. Spaces between the wood slats allow natural light and ventilation into the parking garage reducing operating costs. An outer steel mesh skin protects the exterior staircase creating a buffer zone to the facade. Exterior lighting along the façade lights up the area at night creating a sense of security.

  1. Excellent case studies, and good summary. I'll look up the car park example, but am familiar with the other ones.

    I recommend that you also look up the Loyola University Information Commons in Chicago. Transsolar was the environmental consultant. They use passive ventilation in a more humid environemt than England and Germany.

    Built Ecology (a subset of WSP) is working on or has finished by now a couple of projects in Virginia that use passive ventilation for the buildings. As you probably know, the humidity there is on the high end. They have a couple of approaches to getting the moisture out of the air as it enters the building.

    I couldn't find the BE case studies on their web site, but will see if I can get any information on them.

    Also look at the drop box folder for readings on ventilation, if you haven't already.

    1. It'll be amazing if you share the case study using passive ventilation in humid regions with me.It'll be of great help to me.

  2. Chris,

    The parking structure is quite elegant, as seen from the photos on the web site. Do you have more information, like plans, sections, diagrams?

    If you are interested in the buffer zone created by the mesh screen around the perimeter, you might also look at the Dripps+Phinney Studio and what they call "Constructing Weather." You can also read about Robin Dripp's land speed record there.

    The project also reminds me formally of the U Penn Chiller Plant by Leers Weinzapfel.
