1180 Peachtree, also known as the “Symphony Tower”, is a 780,036 square foot, 41-story office tower developed by Hines and completed in February 2006 in Midtown Atlanta, GA. The building was the first high-rise office building in the southeastern United States to receive Gold certification under the LEED BD+C: Core & Shell rating system. The office tower contains several green features. A pedestrian terrace and green roof on the 18th floor provides access to open space for building occupants in a dense, urban area. The building also has a unique water-management system using captured and stored rainwater and condensate from the building’s mechanical system to provide much of the building’s landscape irrigation water, circumventing the need for city water for irrigation. During the LEED performance period, the property performed an ASHRAE Level II Energy Audit to assess areas where efficiencies could be found and energy could be saved. This has helped to gradually raise the building’s ENERGY STAR score, which is currently a 96 – putting the building in the top 4th percentile in terms of energy efficiency for similar sized office buildings. SIG provided LEED Consulting and Engineering services for 1180 Peachtree’s 2nd recertification (and third overall) LEED EB: O+M application in 2019, recertifying at LEED Platinum in October 2019.
