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.

The ecologist has a much more comprehensive and holistic view of the world. We're looking at the natural environment as well as the human built environment and the connectivity between the two - how do the natural environment and the human-built environment interact and interface with each other.

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.

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'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.
