DPW HQ Operation and Maintenance LEED Certification project (Public Buildings)
This project was to provide LEED Existing Buildings Operations and Maintenance Certification for the Department of Public Works (DPW) existing Headquarters building.  The building is a 12 story high-rise office building with a basement and a mezzanine floor.  Through the process of LEED certification, the building has reduced energy consumption, water usage, and material recycling; thus reduced natural resource demands on the environment.  DPW Headquarters building obtained Gold Rating from USGBC in 2011.
