SOLUTION - Case Study: Bill Dunster Architects, Bedzed, Hachbridge, Sutton, United Kingdom

Design principles

∙ Zero energy - All energy is produced from renewable sources generated on site.
∙ High quality - The apartments are finished to a high standard to attract the urban professional.
∙ Energy efficient - The houses face south to take advantage of solar gain, are triple glazed, and have                               high thermal insulation.
∙ Water efficient - Rain water is collected and reused.
∙ Low-impact materials - Building materials were selected from renewable or recycled sources                                    within 35 miles of the site.
∙ Waste recycling - Refuse collection facilities are designed to support recycling.
∙ Encourage eco-friendly transport - Electric and liquefied petrolium  gas cars have priority over cars that burn petrol and diesel.

BedZED is a project launched to provide sustainable lifstyles and building systems 
at the scale of the housinng estate. The architects mandate is to reduce the average 
household’s yearly carbon emission (typically occurring through energy use, 
vehicular use, and food sourcing) and thus its ecological footprint. Situated in a south 
London borough, it includes a mix of eighty-two housing units, workspaces, an office 
park and shared leisure and sports facilities. The project introduces the idea of 
“solar urbanism” to the design of the terraced row house.

Wind scoops capture the breeze for the wind-driven ventilation stacks. Using the
heat from the outgoing stale air, the heat recovery system perheats incoming fresh
air throughout the buildings. Omitting a fan assisted mechanical system, the system
reduces carbon emissions as well increasing general efficiency. The passive ventilation
system is one of the features of the ZED in a box standard housing type that the firm
is selling as a carbon-neutral housing kit to introduce sustainability to the construction
and development industry.
