Where is Xeritown to be located?
What is the highest daily temperature in the area where Xeritown will sit?
100 degrees Fahrenheit (38 degrees Celsius)
110 degrees Fahrenheit (43 degrees Celsius)
120 degrees Fahrenheit (49 degrees Celsius)
How much average rainfall do most deserts receive?
10 inches a year (25.4 centimeters)
15 inches a year (38.1 centimeters)
20 inches a year (50.8 centimeters)
What is a common name given to people that spend their lives in the desert without special buildings?
On what do nomads rely for sustenance?
plants that grow near desert oases
small livestock herds
What is the principal behind the design of the proposed Xeritown?
to take advantage of the desert in ways that will achieve self-sustainability.
a geostatic dome that uses photovoltaic cells to generate electricity for cooling
solar technologies to create a cool environment using less energy than a typical city
What is xeriscaping?
planting moss and lichen to reduce use of water for irrigation.
using drought-resistant plants that are planted in a way to efficiently use water
using volcanic rock and perforated plastic channels around plants to retain water
What is another aspect of xeriscaping that people?
It's ideally suited to climates with extreme temperature changes.
It produces intensely colored blooms and foliage.
Plants require very little care after the initial planting.
What will make Xeritown different from any other city located in an arid environment?
Parks and sidewalks will be underground.
All the buildings will be coated with reflective paint.
The town will use natural and fabricated solutions to promote a low energy cooling effect.
How do the architects plan to cool Xeritown naturally and without using excessive amounts of energy from fossil fuels?
The buildings are oriented to suck cool air from the sea between islands of development.
Water from the sea will be circulated under streets and sidewalks to cool the air temperature.
Photovoltaic panels in a solar farm and on building roofs will provide low-cost energy for cooling.
How will hot winds be dealt with in Xeritown?
Xeritown will be built behind massive sand dunes that naturally block the desert winds.
Building heights will be low and at an angle designed to push the hot desert air up and over Xeritown.
After cool breezes from the Persian Gulf pass between the buildings, they will push hot desert air up and away.
How do architects plan to shade the streets, sidewalks and parks?
Thousands of palm trees planted through the development will provide shade from the sun.
Tinted translucent panels that look like ship sails will be installed at angles to block the sun.
Groupings of giant flat circles will hang over the sidewalks in areas not shaded by buildings.
How do architects plan to light the streets in Xeritown?
solar panels that provide electricity for traditional street lights
dimmable light-emitting diodes
sodium vapor lamps
Where will water come from to maintain the plants used for xeriscaping?
the Persian Gulf
treated water from sewage
gray water or industrial wastewater
What was the percentage rate of economic growth in 2007 that made Dubai famous the world over?
