[NEXT] Building the future


24 Jul 2002. Imagine a housing development constructed from sustainable resources
that uses no fossil fuels, produces no net CO2, recycles household
waste, provides a crèche, sports club, and solar-powered electric car,
is located in a desirable area — and is affordable. Sounds too good to
be true? The truth is that this futuristic place already exists, in
southwest London. Beddington Zero-Energy Development (BedZED) is
sustainability in practice. This ground-breaking, energy-efficient
eco-village comprises some 80 homes and enough office and work space
for 200 people, all tucked away in the south London borough of Sutton,

The pioneering initiative was born from an idea conceived and
initiated by the BioRegional Development Group — which has a vision of
local sustainability — and leading architect Bill Dunster. BedZED was
developed by the Peabody Trust, which is committed to providing
high-quality, affordable housing for people on low incomes. The Trust
has partners from the mainstream engineering, construction, and
quantity surveying companies Arup, Ellis and Moore, and Gardiner and

The conservation organization WWF also supported the project
from the beginning. Work began on the brownfield site in May 2000. In
the words of the developers, the aim was « to make sustainability easy,
attractive, and affordable ». The overall objective is to enable people
to live in a sustainable way — within an « ecological footprint » of two
hectares, the per capita environmental space available globally — but
without sacrificing the comforts and advantages of a modern, mobile
lifestyle. This approach paid off, and by July the same year the
project had won a prestigious Royal Institute of Builders and
Architects (RIBA) award for excellence in housing design. BedZED is now
nearing completion, with the first residents moving in. Apart from
producing no net CO2 from energy use and using no fossil fuels, BedZED
addresses a range of environmental, social, and economic concerns. For
example, Forest Stewardship Council (FSC) certified timber and
reclaimed steel were used for construction. In addition, most
construction materials were sourced within a 60km radius of the site,
reducing pollution and environmental damage by minimizing freight
transport. BedZED derives all its energy from renewable sources. The
homes are highly energy efficient: heating is reduced by 90 per cent
and total energy consumption by 70 per cent compared to conventional
homes. The development also incorporates combined heat and power
generation as well as state-of-the art photovoltaics for solar
electricity. In addition, a solar electric car pool has been set up for
use by the householders. The development harvests rainwater, uses
water-saving appliances and systems, and recycles sewage water through
a reedbed « Living Machine ». Household waste is also recycled. The homes
are for sale at comparable prices to conventional houses in the area,
with 60 per cent of the homes retained by The Peabody Trust for people
on low incomes. By using local materials, the project has supported
local economic development and at the same time created a number of new
jobs related to maintaining the water treatment systems, power plant,
woodchip supply, car pool, and local food deliveries. In addition the
eco-village will have a range of community facilities such as a healthy
living centre, sports club and playing fields, village square, crèche,
and café.

As a result of the success of this pilot project, WWF,
BioRegional, and Bill Dunster Architects have teamed up with the
Midrand EcoCity Project and a number of business partners* to make a
twin BedZED in South Africa. The « Zero Energy Development » (ZED),
located in Ivory Park in the Johannesburg area, has the full support
and involvement of the local community, which has land and planning
permission for an eco-village development of 30 homes and a community
Working with South African architects and engineers, the ZED team will
adapt the design strategies for application in South Africa. The aim is
to build low cost, very high environmental performance buildings that
reduce energy needs, maximize on-site opportunities for renewable
energy, and minimize water consumption. The project will also include
water recycling facilities. The returns from energy efficiency and
renewable energy are particularly great in South Africa, where
electricity supplied by the national grid is generated by inefficient
and polluting coal-fired installations. This is just the beginning of
what could prove to be a worldwide housing revolution. The existing
partners are interested in rolling out the concept, initially at a
regional level and subsequently developing a series of twinning
projects across the globe. The future is ZED! (731 words)

WWF’s mission
WWF’s mission is to conserve nature and ecological processes, to seek
the sustainable use of natural resources, and to promote the reduction
of pollution and wasteful consumption whilst recognizing and respecting
human needs and livelihoods. WWF’s aim is to slow down, and eventually
reverse, the accelerating degradation of our planet’s natural
environment; and to help build the future in which people live in
harmony with nature.

The BioRegional Development Group
Established in 1994, the BioRegional Development Group
is founded on the green ideal of local production for local needs. The
Group takes a market-led approach to sustainable development and
promotes the application of appropriate technology. Their vision of the
future is a network of regional industries based on sustainable
land-use, providing fulfilling employment and maintaining biodiversity.
The Peabody Trust
The Peabody Trust
is London’s largest charitable housing trust, and a registered housing
association, providing over 19,500 homes across the city. Unusually, it
has its own Act of Parliament, stipulating the Trust’s objectives to
work solely within the London region for the relief of poverty. The
Trust is also a leading force in the regeneration of London, working to
provide people with affordable housing in thriving, sustainable

Ecological footprints
Ecological footprints
are a conservative measure of the environmental impact of human
activities. An ecological footprint represents the biologically
productive area required to produce the food and wood people consume,
to give room for infrastructure, and to absorb CO2 emitted from burning
fossil fuels. The ecological footprint is expressed in « area units »,
where each unit corresponds to one hectare of biologically productive
space. Each person can use up to two area units a year for all their
activities without damaging the environment.
Forest Stewardship Council
The Forest Stewardship Council
(FSC) is an independent, non-profit, non-governmental organization
committed to good forest management worldwide. Founded in 1993, the FSC
supports environmentally appropriate, socially beneficial, and
economically viable management of the world’s forests.
The main activity of the FSC is to accredit organisations that certify
the quality of forest management. Certification is the process of
inspecting forests to see if they are being managed according to an
agreed set of principles and criteria. These include recognition of
indigenous people’s rights and forest workers, long-term economic
viability, protection of biodiversity, conservation of ancient natural
woodland, long-term responsible management, and regular monitoring.

Living Machines
Living Machines are man-made systems that simulate the water
purification observed to take place when polluted water is led into
naturally occurring wetlands. A complete system for wastewater
treatment, they can be used for domestic and municipal sewage treatment
and also for industrial effluents. The treated water can be recycled
for non-potable uses or discharged directly to the environment.

Midrand EcoCity Project
The Midrand EcoCity Project
is a partnership between Johannesburg City Council and the
non-governmental organization, the Midrand EcoCity Trust. It was
established in 1999 by the Midrand Town Council and is now ‘owned’ by
the Johannesburg council and driven by the Midrand EcoCity Trust. The
project is a needs-driven people’s programme that addresses poverty
alleviation through local economic development.
