The Mammalian Genetics Office Building at Oak Ridge National Laboratory (ORNL) was awarded ENERGY STAR® recognition on September 24, 2004 by the Environmental Protection Agency, outperforming more than 90 percent of the office buildings across the United States in terms of energy efficiency. This is ORNL's second ENERGY STAR® building and the first obtained under ORNL's new In-House Energy Management "Model Program" studies funded by FEMP's Departmental Energy Management Program. This building joins ORNL's Buildings Technology Center Headquarters and other federal buildings that have achieved the prestigious rating, and provides an excellent example of the energy efficiency that can be achieved with limited investments in technology and close attention to detail in operating the building's energy-consuming systems.
Constructed in 1992, the two-story, all-electric, 7,000-square-foot office building has about 30 occupants, many of whom utilize their offices to support research activities in nearby buildings. Significant electrical loads are for heating and air conditioning, personal computers, and office support equipment. An energy management system was installed at construction, and the building contains T-8 lighting and electronic ballasts. The building also includes numerous through-the-wall HVAC units controlled by the building occupants and by the energy management control system (EMS), which has over-ride timer controls in each room. The EMS turns the units off during non-occupied periods unless space temperature dictates a need to maintain the off-shift temperature or an occupant over-ride timer is activated.
Although the building does not contain occupancy sensors, Wayne Parker, ORNL's energy manager, states that contributing factors in enabling the award were not only the management of utilities when occupants are present, but also their dedication to the reduction in energy consumption when they leave the building to either conduct research work elsewhere or go home at the end of the day. This example demonstrates that the greatest energy savings are achieved by turning off lighting, equipment, and systems when they are not needed.
