Maplewood Park (Maplewood), a 110-unit multifamily apartment complex in Union City, Georgia, completed major renovations under the guidance of a third-party green building certification program in October 2012. Oak Ridge National Laboratory (ORNL) partnered with Southface Energy Institute (Southface) to use this project as a case study of energy retrofits in low-rise, garden-style, multifamily buildings in the southeastern United States. This report provides a comprehensive profile of this project including the project economics, findings of the building audit, and results of the analysis of energy retrofit measures specific to this project. With a main focus of energy retrofits, this report aims to discuss other aspects of multifamily building retrofit that would benefit future projects in terms of improved building audit process, streamlined tasks, and higher energy savings in low-rise, garden-style apartments. Maplewood received Low Income Housing Tax Credit (LIHTC) financing via the 2010 Georgia Qualified Allocation Plan (QAP). To be eligible for QAP funds in Georgia, all major renovations must incorporate energy-efficiency measures and adopt a third-party green building certification. Because of the unique demands of this financing, including requirements for long-term ownership, property owners were also especially motivated to invest in upgrades that will increase durability and comfort while reducing the energy cost for the tenants.
