I think green buildings are extremely important but it's only part of the equation. A lot of people think that if I put a green building everything is going to be fine, but actually it's not just the green buildings we need, but green businesses, green governments, green economics. We have to extend the greening of buildings to our business and our lifestyles - that is the most important thing to do next.

In most ecological systems you have a composite, biotic components as well as abiotic components acting together to form a whole, whereas in a human built environment most of the components are abiotic or they are inorganic. One of the first things we need to do is to complement the inorganic components with more organic components, and to make them interact to form a whole.

I think buildings should imitate ecological systems.

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.

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.
