On June 28, 2016, the Atlanta History Center and historic Swan House, in Atlanta, Georgia, were recognized as one of the Atlanta Better Buildings Challenge’s 2015 top performers.
The Swan House’s performance was based on complete utility data entered in ENERGY STAR ® Portfolio Manager ® through December 31, 2015. The Swan House energy use is down 30% due to smarter scheduling and HVAC modifications that allowed temperature and humidity levels to drift seasonally, and careful use of power by staff and security utilizing the building. Additionally, water supplied by the City of Atlanta decreased 60% due to the use of AHC supplied well water being used in the air conditioning systems.
Griffith Engineering, Inc. provided retrocommissioning services that identified several options for reducing energy in this historic building including:
▪ Identification of controls sequences that had been causing excessive reheat.
▪ Identification of failed components causing room discomfort and recommendation of replacements.
▪ Confirmed space conditions were not being maintained within the strict parameters that the system should have been maintaining.
▪ Recommended changes /upgrades to consider in order to maintain the strict temperature and humidity requirements of museums while saving energy and protecting the historical structure and artifacts stored here.
The Swan House is a ca. 1928 mansion designed by renowned Atlanta architect Philip Trammell Shutze, and is owned by the Atlanta Historical Society. The house is operated by the Atlanta History Center and is maintained as a 1920s and 1930s historical house museum.
Griffith Engineering was a energy and retrocommissioning sub consultant to Lord Aeck Sargent for this project
