Communities are now lobbying Councils and Politicians to preserve existing buildings not because of thier historical significance or even the prominence of the architecture, but rather the embodied energy within the structure.
This is likely to have a significant impact on future public works developments. In particular I would think that hospitals and stadiums are a prime candidates for this type of community activism.
I also note that the Green Buildings Council in the United States has joined the cause for the memorial Coliseum redevelopment in Portland. Save the Coliseum
Developers look to be safe in the short term but major government sponsored developments have a new risk to add to the books. Particularly those with long development timelines.
