Green building
The green building movement is changing the way buildings are constructed. This movement started in the 1970s, as people began to see that modern life was destroying the environment we all share. Nature resources were being destroyed, energy and water consumption was rising, and so was pollution of all kinds. This environmental destruction has continued, and one important factor has been the way that buildings are constructed. In fact, energy use in buildings represents about 32% of all energy use in the United States.
