Summary : In order to protect the nature, architects and builders look for greener buildings nowadays. They design in a way that can save more energy and water, and utilise the materials that do not harm the environment.
Sunlight is a very useful resources in terms of green design. One good example is the big windows. At Clackamas Highschool in Oregon, big windows allow lots of sunshine to come in and help the school reduce the use of electricity. The sunshine can supply natural heat as well as natural light. The sun's warmth not only keeps you warm in winter, but also it can be used to generate electricity, converted by solar cells.
Another interesting eco-friendly idea is found at Calhoun School in New York. The building's rooftop is filled with grass and flowers, forming a rooftop garden. This keeps the building cooler in summer, warmer in winter.
Furthermore, a new library in Santa Monica makes use of rainwater in drainage system to save water, and many buildings use fast-growing bamboo for floors instead of wood in order to save the trees. Many other green materials such as recycled substances are used to protect the environment.
The eco-friendly tendency is spreading out rapidly thesedays, with the global encouragement. The buildings are certainly becoming healthier and greener every day.
