The New York City Department of Design and Construction (DDC) hired e4, inc., in conjunction with Horizon Engineering, to conduct a three month study of the feasibility of achieving a LEED for Existing Buildings: Operations & Maintenance (EB: O&M) Silver Rating for three City cultural buildings and evaluating the approach as a way to reduce energy consumption and greenhouse gas emissions across the City portfolio of buildings. In addition to these three buildings, e4 also evaluated which credits could be addressed portfolio-wide. This was the first time that the City had commissioned a comprehensive study of applying LEED EB: O&M to their existing building stock.

e4, inc. provided existing building services for the TIAA-CREF New York and Charlotte Campus Headquarters. Both locations were seeking LEED for Existing Buildings Operation & Maintenance (EB: O&M) Ratings and LEED for Commercial Interior Ratings for ongoing renovations. e4 worked with TIAA-CREF to develop, implement and document building operation procedures that reduced energy consumption and improved the sustainability of ongoing operations. TIAA-CREF expanded e4’s initial scope to include achieving LEED EB ratings for every building on the Charlotte campus except its data center.
8500 Andrew Carnegie Boulevard is the centerpiece of TIAA-CREF’s Southern Service Center located in Charlotte,North Carolina. Comprised of five office buildings and one data center, the campus setting presented unique challenges to LEED EB: O&M certification. e4, inc. worked with ownership to develop required operational policies and plans and implement them on a campus wide basis while also focusing on improved operations within the headquarters building. As a result of these efforts, the building achieved LEED Gold certification.
