Nowadays, not only the factories, industries start their journey towards the green future but also many educational institutions like schools and colleges started to prepare their students towards the energy efficient green buildings, green economy and green jobs. By this the colleges can create good citizens for the future with the greater knowledge about the environmentally-friendly features. Some of the colleges started to offer green building courses for the students as a part of their contribution to the eco-friendliness. Here are three colleges that include various excellent the green practices:

College of the Atlantic

college-of-the-atlanticCollege of the Atlantic (COA) at Bar Harbor, Maine, USA was inaugurated on Oct 8, 2006 by the president David Hales had taken an oath to be a Carbon NetZero college by the end of 2007, to achieve that mission, the students, faculties and the staff worked together and carried out many researches and analyses to offset the green house gas emission. As on Dec 19, 2007, COA invested in a green house gas reduction project operated by The Climate Trust of Oregon to offset the 2,488 tons of carbon output over the past 15 months.

By obtaining the electricity through a low-impact hydroelectric generator in Maine, COA reduced its annual green house gas emission and this will be further reduced by 22 percent or about 450 tons by next year. Incandescent light bulbs have been replaced by compact fluorescent where possible. This college makes use of the natural light by installing light shelves, which bounces the light from the windows to ceiling to lights the interior of the rooms. Commuting methods such as carpooling and biking promotes the employees to work from the home.

COA uses only certified woods, not from the old-growth forest and no materials that emit gas-chemicals. COA uses a renewable wood pellet boiler to heat 20 percent of the college campus. It keeps the temperature as 65 during the day time and 50 at night time. Coolant from air-conditioning in library stacks and kitchen used to preheat the hot water. All toilets, urinals, faucets and shower heads use less than three gallons of water.

Berea College

berea_kyBerea College at Berea, Kentucky, amazingly locates an Ecovillage that occupying a 5 acre eco-friendly community. The complex includes 50 apartments, a state-of-the-art Child Development Laboratory, a common house and a Sustainability and Environmental Studies (SENS) demonstration house. The Ecological machine, wetlands, permaculture food forest and individual gardens are the other community features. This energy efficient Ecovillage reduces the energy usage by 75 percent, water usage by 75 percent.

Ecovillage recycle and reuse 50 percent of the sewage and waste water. Skillfully, Ecological machines are used to convert the sewage water to swimmable quality water. This village also incorporates passive solar heating, photovoltaic panels andwind-powered. The roof top captures the rain water used for the landscape irrigation and for the production of fruits and vegetables. Berea college maintains it own farm to provide the organic produce, beef and pork.

Evergreen State College

evergreenGreen roof of the new building is a greatest highlight of Evergreen State College at Olympia, Washington. This building is being evaluated for the LEED-Gold rating under the USGBC. This tremendous green roof builds 24,000 square-feet on 13 separate green roof areas. This green roof is a live visual representation to develop the sustainability. Roughly, $18 is incorporated for a square-foot with polyisocyanurate insulation with an R-value of 21, bitumen roof system which incorporates recycled materials and stainless steel flashings.

Green Roof uses Garland’s filterdrain 110 as the drainage layer. It is a very high density polyethylene filter fabric fused to a geotextile filter fabric. A drip irrigation system will be used only during the severe drought periods. Important advantage of this green roof is it reduces the size of the storm water preservation ponds. The green roof collects, filters the rain water incident on it and allow it to flow into a 20,000 gallons reservoir tank, which is designed in such a way to release water back to the environment. The students of this college use benches and patio  areas, arranged around these green roofs as an interaction place with their staff members.
