What does it mean…
• Energy Efficient (High Performance)• Low Impact on Environment
• low use of natural resources• low waste of materials
• Improve Lives• low exposure to unhealthy gases & materials• improved air quality• Improved indoor & outdoor environments

• Compare to 209.7 tons of Municipal solid waste / year

Why make a building Green?
• Reduce energy bills by 15% - 40% per year
• Simple payback on initial cost in 3 to 10 years

LEED Green Building Rating System
• Purpose is to establish consistent, measurable goals for Green Buildings
• Best Practices as mandated by the U.S. Green Building Council
• 8%-10% of all new construction projects are targeting LEED certification
