Can Green buildings save India from going grey?
Buildings at present are being constructed with lots of glass, which in turn increases the temperature of the building. The amount of energy needed to cool the building is enormous. How is this balanced?
Pankaj Gupta: Technology has helped us to ease many difficulties in our life. One is nanotechnology, which has been applied in glass frames. This helps the entry of light into a building but reduces the amount of heat entering the building. Air conditioning in large buildings should be centralized and CFC-free to reduce pollution. Ideally the energy used for cooling a green building should be obtained from solar voltaic cells installed in the building itself. Green building requires 30% more of fresh air therefore; ideally the outgoing air is renewed and brought back to the system.
