“How can we quantify the sustainability of buildings?”
Buildings are amongst the most important facets of our civilization. Because of them, we can live, work, and play freely. But like most things created by humans, they take up environmental resources. And since we want to be as sustainable as possible, we need some way to measure the environmental impact of each building. That’s why the United States Green Building Council has developed a certification system called LEED. LEED works by giving “points” for each sustainable activity the building does, whether it be brownfield redevelopment energy optimization, or using regional materials. Based upon these points, the building may be awarded a LEED certification (with levels specified by the figure) and become eligible for incentives such as tax credits. Because of the system’s success, numerous countries around the world have expressed interest in the system, including the rapidly developing India and China.
