I feel that more often than not - materials deemed to be "Green" - are not! Why? The embodied energy for the material never entered into the equation. For example, so-called "Strawbale Construction" is perhaps the least "Green" material on this planet - because of embodied energy.

At the same time aging has to be considered. Again, aside from the health issues related to vinyl windows - vinyl windows change drastically as they age - because the components alter and allow massive air infiltration (even though it was excellent in preventing infiltration when new). Unfortunately aluminum windows age better than any other type butter are one of the worst materials on this planet when it comes to embodied energy. The avage alumuminized potatoe chip bag likely costs $6 in electricity utilized in production (in Jamaica).
