Answer: Good for the environment and fair for
local people.
Sustainable Community
• A community which is
designed to have minimal
impacts on the
environment. Such
communities may make
use of energy efficiency,
renewable technologies
and also make use of local
employment and services
to reduce the impacts of
commuting.

development
(such as a
housing estate)
that does not add
any extra carbon
dioxide emissions
to the
atmosphere over
its lifetime.

BedZED claims to be the UK’s largest sustainable community. Built in 2002, it
has 100 homes designed to provide ordinary people with a high quality of life
while living within their share of the earth’s resources.
BedZED, in Beddington, south-west London, was built on a brownfield site on
previously industrial land. Fifty per cent of houses are for private sale or rent,
25% for shared ownership and 25% social housing for rent

In a BedZED home energy use for heating and hot water is reduced 81% by
simple things like south-facing windows and triple glazing. Electricity
consumption is reduced 45% by low-energy lighting and appliances
BedZED walls are thicker than average, with insulation between the bricks to
prevent energy loss. The building materials have used less energy to make and,
where possible, are locally produced
A combined heat and power plant was designed to burn BedZED waste to
produce hot water and electricity. But technical and commercial difficulties
mean the system is not in operation and will be replaced. Effluent from the
buildings is treated on site and the water is used for flushing toilets
A distinctive feature of the buildings is the wind cowls on the roofs.
These cowls ventilate the houses and recover heat from the air coming
out. The roofs are covered by solar panels (to generate electricity) and
plants (for insulation and a habitat for wildlife)
People separate their waste in their kitchens to make recycling and
composting easier. Sixty per cent of waste is recycled, three times the UK
average. Residents encourage each other to recycle
BedZED has a green transport plan to reduce car mileage. There is a carsharing club and electric car charging points. Good public transport links and
cycle storage spaces are also provided

Beddington Zero Energy Development or BedZed case study
Example exam question
“Use one or more named case studies to describe
the features of a sustainable settlement.” (6
marks)
• Introduction: What is Bedzed and where is it?
• Main part: What have they tried to achieve/ how
have they tried to achieve it? Split into sections
such as: energy, transport, community, housing
etc)
• Conclusion: what do you think of their
achievements? Is Bedzed a success? Refer to the
evidence you have collected
Homework task
