Sustainable Development & LEED Certification

(Leadership in Energy & Environmental

Design)

LEED is an internationally recognized green building certification system,  providing third-party verification that a building or community was designed and built using strategies aimed at improving performance across the metrics that matter most: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts (www.USGBC.org).

What is LEED?

Leed Rating Systems

• New Construction • Existing Buildings: Operations and Maintenance

• Commercial Interiors

• Core and Shell

• Schools

• Retail

• Healthcare

• Homes

• Neighborhood Development

LEED points are awarded on a 100-point scale, and credits are weighted to reflect their potential environmental impacts

• Certified• Silver • Gold• Platinum

1. Lowering operating costs and increasing asset value. 2. Reducing waste sent to landfills. 3. Conserving energy and water. 4. Developing healthier and safer buildings for occupants. 5. Creating compact and walkable communities with good

access to neighborhood amenities and transit 6. Protecting natural resources and farmland by encouraging

growth to be located in areas with existing infrastructure. 7. Reducing greenhouse gas emissions. 8. Qualifying for tax rebates, zoning allowances, and other incentives. 9. Demonstrating an owner's commitment to environmental stewardship and social responsibility.
