The Department of General Services (DGS) completed a $7.5 million (Federal Stimulus Dollars) Energy Retrofit Project to reduce the energy consumption of one of the District's busiest office buildings; One Judiciary Square, located at 441 4th Street, NW. The building has 875,000 gross square feet area and accommodates 20 District government agencies. Under the OJS Energy Retrofit project the building received a new building management system, digital controls and upgrades to the heating, ventilation and air conditioning system. The project created the equivalent of 16 full-time construction jobs. This project was awarded to Pepco Energy Services in August 2010 and was completed by Winter 2012. The District was targeting 20 percent saving in Energy cost at OJS by the time the project was completed. The retrofit project was mainly funded by American Reinvestment and Recovery Act (ARRA) through the DC Department of Environment.
