This is a great example of a modern school with great environmental credentials. Have a look!
In Europe there are companies now offering new school buildings essentially for free. The model works by having the school roof composed of solar panels. The school sells the energy to the grid over 15 years and can therefore pay for the money that has been borrowed to build the facility. Additionally the school receives free electricity from this approach. If you are interested in such an approach for your school let me know and i can put you in touch with the people that do this.
