In my heart I believe that biology is the beginning and the end of everything. It's the biggest source of ideas, the biggest source of invention. Nobody can invent better than nature and so if you like nature is my biggest source of inspiration.

I'm eternally optimistic about the future. I believe that if we are committed towards it and if we continue to educate people and get the whole world community to implement green features and aspects in not just the built environment not just in their lifestyles but in their businesses in their industries then we're heading towards a green future.

I think buildings should imitate ecological systems.

I think buildings should imitate ecological systems. Ecological systems in nature before we had human beings you know interfere with them exist in a state of stasis - they are self-supporting, self-sustaining.

In nature the only source of energy is from the sun. So in ecological systems everything comes from the sun through the process of photosynthesis whereas now in human built environment our source of energy is from fossil fuels, renewable, wood energy or hydro-energy but it is not from the sun. So until we are able to operate and run a human built environment by imitating photosynthesis it will be a long while before we can have a true eco-system.

We shouldn't just look at new buildings but at existing stock building because that's an even greater problem than the new buildings being built. The renovation of existing buildings and making them green is just as important as designing new green buildings.
