Challenges and Issues Statistics
Population growth 2.1 % every year
Water scarcity 41% scarcity
Air pollution Ranked 6th reason for death
Health infrastructure 21% of the world’s disease
burden rates of maternal
and infant mortality.
Energy consumption 80 TWh in 2000 to 186 TWh
in 2012, and constitutes
22% of total current
electrical consumption

Materials used in the interiors:
• Polished Concrete flooring-Low cost, low
energy and durable
• Particle Board-Sustainable replacement for
wood used in interiors
• Low VOC paints-To improve indoor air quality
• Eco friendly fabric-Easy maintenance and to
protect the indoor air quality

• VRF HVAC System is used because of low
cooling energy and hence more reduction in
EUI.

Oasis Abode will act as an affordable energy efficient
prototype that can be used by the developer in India.
Aesthetically similar to typical houses, is based on vastu
principals and therefore is an easily marketable solution.
