Roanoke Achieves 16% Energy Savings Since 2009
The city of Roanoke, Va., through the DOE’s Better Buildings Challenge, has committed to 20 percent savings by 2020 across more than 25 buildings, covering one million square feet. Roanoke has already achieved 16 percent energy savings since 2009, and its Better Buildings Challenge showcase project, a retrofit of the Berglund Center, is expected to result in 30 percent energy savings, totaling $180,000 annually.
The Berglund Center is a 390,000-sq-foot entertainment and convention center. In 2011, Roanoke first conducted a comprehensive assessment of the civic center and identified strategies to reduce energy use. The city then allocated $750,000 to retrofit and replace heating and cooling systems, upgrade lighting, and implement a system-wide operations and maintenance schedule to ensure that all systems were running at efficiency.
The city’s facility manager hired skilled professionals to staff Roanoke’s energy management team and perform all retrofit activities and building maintenance. The team installed a highly efficient cooling system, which cut cooling costs by 50 percent. The city also upgraded to high efficiency lighting throughout the facility and created strategies such as controlling lighting by zones.
Across the country, Better Buildings Challenge partners are deploying energy efficiency projects at more than 9,000 facilities, with more than 2,100 buildings improving efficiency by least 20 percent, and another 4,500 by at least 10 percent, compared with their baseline years.
