One of the things which makes working today different from, say, 20 years ago, is the consciousness of the need to make buildings which are not only ecologically sensitive but which also reduce energy consumption and are thoughtful in terms of energy-saving methods. So that buildings, you know, like the Smith House, you know, would no longer be possible today. The code wouldn’t even allow it, you couldn’t have that amount of glass. It’s something of the past and so today, you know, what one has to think about is very judicious use of... of open transparent surfaces in order to maximise the energy-saving elements within a building. And right now, in fact, one of the projects which we’re doing in Italy is... is going to achieve a Platinum Leads Certificate because not only is the building energy efficient in every way, but you know, the water is recycled within the building. Every material is thought about in terms of its longevity and its quality. Every aspect of the building, you know, is, sort of, given a mark, as it were, in terms of it's energy consciousness.  So this changes the architecture and it changes the expression of the buildings.

[Q] And for example these glass buildings?

Well, the glass in many of these buildings has a U-coating to reduce the amount of solar gain within the building. It’s probably, at least double, maybe triple glazed, you know, single glazing just wouldn’t be possible in these buildings. It has all kinds of, I would imagine, you know, solar controlling devices.
