I go to Sandy High School in Sandy Oregon, and this year I took a trip with the Green Club at school into Portland to view some of the many eco-friendly green roofs installed on several large and small buildings throughout the city. There was even a middle school with an eco-garden. After the trip I was very impressed by how effective and efficient these green roofs are. Within the next four years we are supposed to have a new high school built, up and running. The blueprints and such are currently in the works, from what I know, and evidently the architecht is environmentally oriented.
