"We can't really demolish it until we finish building it."

"In the UK, post-occupancy evaluation is about people and making their lives better at lower cost to all. In the US it seems to be more about product validation."

"This is a luvvies award - an award for doing it, not for doing it well."

"In geographical parlance, the built environment produces space-time; it is naturalized as the taken-for-granted and normal. This means that changing the built environment is as much a social and psychological challenge as it is a physical and financial one. "

"First see that the design is wise and just; that ascertained; pursue it resolutely."

"I've seen many low-carbon designs but hardly any low-carbon buildings."

"It is easier to introduce new complications than resolve the old ones."
