We should conduct more green buildings! I have read some papers about green building.I think it is good to construct green buildings instead of regular buildings. In the past decades, the construction industry in China has got a very high-speed development. It has made a remarkable contribution to the rapid growth of gross domestic product. However, a great amount of environmental problems were raised at the same time. In order to reduce the negative influence to the nature, and save energy and cost during the life cycle of a building, the new concept of sustainable building was put forward. Sustainable buildings can be defined as the facilities which are the outcomes of sustainable construction for the purpose of promoting occupant health and resource efficiency, minimizing the environmental impacts of the construction procedures. Through a flourishing development due to a growing market demand for environment-friendly solutions and products, the green philosophy is now widespread in the construction industry.
