dome roof used
for toilets
- Rain falling on
supermarket roof
used to water
plants
- Waste water from baths, showers and
wash basins in village homes is filtered +
used to flush toilets + water plants
- Saving energy
- Supermarkets use
electricity for light, heat
and fridges
- Makes some of
its own - wind +
solar power

side to keep warm in winter
and cool in summer
- Glass roof lets light in
- Village houses
- Well insulated

delivered
- Abu Dhabi, Masdar (Carbon neutral city)
- World's first
carbon neutral
city
- Designed to be without cars
and skyscrapers - powered by
the sun
- Only way to survive inhospitable
terrain is with technological
support
- Need to combine 21st century
engineering with traditional desert
architecture
- Built the biggest solar farm in the
middle-east to power city and offset
inevitable burning of diesel and baking of
cement in construction
- 1 projected =
circle of mirrors
reflecting towards
a tower
- Heat energy
powers heat and
drive generators
- Narrow street - buildings
shade one another
- Surrounded by a
wall - stops
over-expansion
- Wind towers encourage a breeze
- cools streets with no energy use
- Conventional
cars must be
checked in at
gates
- Pedestrianised
streets - 'foot
friendly'
- Personal rapid
transport + pod-cars
- Driverless vehicles
guided by magnetic
sensors - powered by
solar energy
- Quality of air will be
better than anywhere
in the Gulf + world
- On top of wind tower, light
portrays energy efficiency -
Red = too much Blue = just
right
- 45m tall + visible for
miles around
- Curitiba, South Brazil

- Prioritising people

parks circle city -
greenbelt
- Built parks in 2 months
- Increased land value
+ created 'leisure
paradise'

maintained,
variety of
landscape

- Has 4x
recommended
green space
per resident

- Helping poor
- Equation of co-responsibility

plants absorb co2
- Review methods of travel
- reduce amount of petrol
used
- 'Think before you fly'
- uses enormous
amounts of fuel
- Buy local goods - reduce
transport needed for
delivery + boosts local
economy
