Beddington Zero Energy Development

The first ever sustainable, carbon-neutral compound development project in Britain, the BedZed, has been developed as a compound housing, office, and business complex.

Overview
  • ㆍLocation : Sutton, London, UK
  • ㆍArea : 16,500m²
  • ㆍNo. of Households : 100
  • ㆍBackground and purpose of the development project :

    - The complex was developed using zero energy technologies on the site of a former waste water treatment facility (Total area: 16,500m²).

    - Various entities, including the low-income class, social work groups, community environmental activist groups, architectural companies, quotation companies, engineers, designing companies, etc., cooperated in development of the new, environmentally-friendly city.

 

Principles and Characteristics of the Project Plan
  • Aimed to realize zero energy

  • Improvement of energy efficiency and recycling of water

  • Eco-friendly transport reducing carbon emission

  • Adopting various renewable energy sources, including solar energy

  • Energy saving architecture directed to realize a low-carbon city

 

Achievements
  • ㆍEnergy : Compared to the average energy consumption in the area, the facility saved 81% of the energy used for heating and 45% for electricity. Also, the facility achieved a 64% saving effect compared to the average automobile usage in the area, which was 2,318km per year.
  • ㆍWater resource: Saved 58% from the average daily water consumption of 72 liters per capita.
  • ㆍGargabe reusing : 60% of the total garbage volume is reused.
  • ㆍFood : 86% of the residents in the community purchase organic food materials.
  • ㆍLocal community : Each member of the community knows around 20 neighbors by names, indicating a higher level of intimacy among the community members.
 

Challenges
  • ㆍTechnical challenges :
    It was attempted to use the biomass boilers to serve the hot water needs as well, in the BedZed town. However, due to the noise and frequent equipment failure, they are now using city-gas.
  • ㆍInsufficient infrastructure to support electric cars :
    The community had 10 charging stations. But, the lack of use of electric vehicles renders the stations virtually useless.
