Summary- Green building menas a building which consist of materials that have no damage on environment. These days, a number of people try to build these green buildings to save energy and water.The buildings which are facing South and have large windows can accept huge amount of sun light. It makes it possible not only to get heat but also to store them in solar cells and use as aeletricity. And extra energy are be used in other buildings' other systems.Garden on roof can block much more sun light than ordinary roof, and it makes the building cool inside. Also in winter, plants and soil block the heat's escaping.Actually, there is not much water that is able to be drank. So green building use fresh water and they reuse it. For an example, a new library in Santa Monica, California store rain drops and use them as plants' water or toilets' water.Trees in the world are not enough because of deforestaion. So green building use bamboo. Bamboo is a grass, so it grows far faster than other trees. Green building also save our forest.Old thrown away things are able to be used as parts of green buildings as well as environmental sources.There are not so many green buildings now in cities, but many people support them building them. So the number of this type of buildings are increasing. The city would be more healthier and greener.

If we build green buildings by the way this book said, we can leave much better future for our offsprings. I feel very very good.
