Environmental Impact of Materials

The choice of windows can add value to a structure and the environment. The most commonly used evaluator of a structure’s environmental impact is the U.S. Green Building Council’s LEED® (Leadership in Energy and Environmental Design) Green Building Rating System. This guide for designing, constructing, operating, and certifying buildings is based on accepted energy and environmental principles.

LEED’s measurement standard follows a point system. The four levels of LEED certification and required points for each are:

The points are earned within six categories. The five environmental categories (not including Innovation and Design Process) are divided into credits. One or more points are available within each credit, and points are achieved by meeting specified requirements.

• Sustainable Sites: 8 credits, 14 points
• Water Efficiency: 3 credits, 5 points
• Energy and Atmosphere: 6 credits, 17 points
• Materials and Resources: 7 credits, 13 points
• Indoor Environmental Quality: 8 credits, 15 points
• Innovation: 4 points
