Conyers may be the first city to go live with anew green building ordinances mandating that all new residential construction and city government buildings 5,000 square feet and larger met earth-friendly specifications beginning January 1, 2009. The Conyers ordinance cites guidelines from the U.S. Green Building Council’s Leadership in Energy and Environmental Design, or LEED, and Atlanta-based EarthCraft as ways to enhance public health and welfare.
“The city finds that green buildings use key resources like energy, water, materials and land more efficiently than buildings that are just built to code,” the ordinance reads. “They also create healthier work, learning and living environments, with more natural light and better air quality, and typically contribute to improved employee health, comfort and productivity.”
The Conyers City Council will vote on the proposed green building ordinance on October 1.
