What do you mean, "Green School?"
Green schools, or green buildings generally, is a term given to schools that are designed to be environmentally sensitive, energy efficient, and healthy for their occupants. Any building that is hard to heat or cool, that requires a great deal of lighting, that wastes water, uses no recycled materials, or has an unpleasant "feel" to the people who work and study there is definitely not a green school!\n\nAt first, the "green-ness" of this school may not be apparent to you. After all, it feels warm in the winter and cool in the summer just like any other school. And there doesn't seem to be anything odd about the lighting. The doors and windows, walls and floors look pretty routine. So what's the difference?\n\nThe difference is that the architect considered environmental sustainability and operating efficiency at every possible opportunity when designing and equipping the new school.\n\n * Lights and appliances work very efficiently.\n * High tech controls adjust or turn off fixtures or appliances depending on their current use.\n * Non-polluting solar power produces some of the school's electricity.\n * Some of the flooring materials, carpets, and many furnishings are manufactured out of renewable or recycled materials and can be readily recycled when they have to be replaced.\n * Fresh air comes into the school mechanically (rooftop vents draw it into the heating ducts) and through the operable windows.\n * Stale air that is being vented out of the building gives up some of its energy to pre-heat incoming fresh air.\n * Lots of natural lighting creates a pleasant, healthy indoor environment.\n * Exterior windows are airtight and designed to keep heat inside in the winter.\n * No toxic paints, finishes, or polishes were used.\n\n\nThe Green Schools Healthy Schools Project \nThe Green Schools Project establishes community, student, and school-staff pride in your school's building and grounds. It builds an understanding of the school's green systems, ma
Green Schools Alliance - Take Action
The November 2007 report from the United Nations Intergovernmental Panel on Climate Change describes climate change as "severe and so sweeping that only urgent, global action" can head it off. Confronting climate change will require solutions of immense proportions and an unparalleled nature. There are more than 95,000 public schools and 34,000 private and independent schools in the U.S. Schools must be active participants in global efforts to conserve resources, reduce greenhouse gas emissions, and prepare citizens to think and act in new and creative ways. No individual school or subset of schools can solve this problem alone. We must work together now to preserve our planet so that future generations can thrive.

Green Schools : Teach Stewardship
Of the “Four Pillars” discussed in “The Little Green Schoolhouse” report, this is perhaps the most important. Environmental education is the kind of place-based education that, according to analyst Jack Chin, “provides students with opportunities to connect with themselves, their community and their local environment through hands–on, real–world learning experiences…[that] enables students to see that their learning is relevant to their world, to take pride in the place in which they live, to connect with the rest of the world in a natural way and to develop into concerned and contributing citizens.” What better place to start than in the place known as school? Let’s teach students about --
* the resources their schools consume, and involve them in making consumption more sustainable.
* toxics issues in and around schools, and involve them in minimizing their use.
* gardens and food systems, and involve them in growing their own food.
If we invest the time and money to teach our children these lessons in precaution and sustainability, they can play an integral role in making our schools, communities, and planet more sustainable and healthy.
