"Green building" is not a new terminology. The underlying concept is to improve current design and construction practices and standards so that the buildings we build today will last longer (that means more sustainable), be more efficient, cost less to operate and contribute to healthier living and working environments for occupants, thereby helping to increase productivity.
Green building is also to increase the efficiency with which buildings and their sites utilize energy, water, and materials; protect natural resources; and improve the builit environment so that ecosystems, people, and communities cna thrive and prosper.
