10 sustainable buildings

Recently, I found an interesting site about 10 sustainable or green buildings in the United States. These buildings are mainly water and energy sufficient out ­of environmentally friendly materials and the purpose is to show encouraging examples of different green building methods. Unfortunately the buildings are quite expensive but in the long run, the cost may be equal because of the lower water and energy bills. There is a lot of detailed information about each building and the structures vary enormously between each others. For instance some of them are constructed by renewable resources like bamboo, recycled mild steel or scrap materials from bordering buildings and a great part of the wastes that resulted from the construction were also recycled. On the other hand you can argue about if all of these solutions really are sustainable? See the link below for more information.
