the Sustainable Building

  In regard to the sustainable buildings, there are many attached new nouns, such as, zero carbon homes, eco homes and low energy homes. All of them have been exploring the further relationship between nature and buildings.
  According to the book, the sustainable building bible ," No building can be eco-friendly, by definition...... The best way we can hope for is to reduce the level of unfriendliness." ( This idea is the same with mine)
  "A sustainable home tends to focus on materials and provide accommodation and facilities in a way that has the lowest possible impact on the ecology and on natural resources. That will apply to the build process, the operation of the building and its eventual demolition and/or re-use."
  Designing the sustainable buildings has become a trend. We can see the sustainable buildings all over the world.

  There are three design issues about the sustainable buildings.
  ENERGY: it is a core part of the design. Try to use the new energy, renewable energy and reduce the waste of energy.
  SIZE:the sustainable buildings will be big enough to meet current needs but with the ability to extend or shrink to meet future needs. Designer should to avoid size as a status symbol, preferring other ways of demonstrating his prowess and sensitivity.
  LIFESPAN: for most buildings, extend their lifespan.
