Better use of space, improving the insulation, getting more daylight into the buildings, reducing the energy consumption of the air conditioning and heating systems, making sure that the internal air quality is good, that we have increased natural ventilation opportunities in the mid seasons. You know these are some of the things we can do.

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.

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.

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.

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.
