Designing an energy efficient building is often a challenge in itself. Numerous hurdles need to be cleared; any of them have apparently little to do with 'architecture. Individual ecologically sensitive buildings and environmentally responsible occupiers may lead to a much reduced environmental impact, yet this is highly localized and could be perceived as being of negligible benefit to the environment or indeed the city unless the subservient infrastructure evolves in a manner with actively promotes a way of living that makes the best possible use of resources, whilst contributing towards a greater standard of living for the community as a whole.

In order to understand a scale 'beyond the building' research teams produced timelines of Portland's infrastructure.
