Any discussion on buildings would do well to start with energy and its cost, both in terms of monetary value and carbon footprint.
In the past we have built our environment using technologies and designs that assume a plentiful supply of low cost energy, an approach driven partly by the promise (in the early 60's) of boundless nuclear power. "The recent proliferation of technology, cheap accessible energy sources and exciting new materials have encouraged us to solve building problems differently" warns Chris Reardon, who goes on to make the telling statement that sustainable buildings are not new at all, but rather a lost art. An art that was honed years ago during an era of expensive and limited energy.
