Virginia building green HVAC upgrades expected to reduce energy use, costs
Trane recently presented the Virginia Department of Motor Vehicles with the Energy Efficiency Leader Award, which recognizes the agency as a national leader in reducing environmental impact.
Agency officials expect recently completed upgrades to the state DMV building located in Richmond, Va., to reduce energy consumption by 36 percent and save $284,000 a year.
“These improvements address building systems that were at the end of their useful life while providing significant cost reductions for the state,” said Richard D. Holcomb, Virginia DMV commissioner. “The upgrades enable DMV to exceed state requirements for energy efficiency while creating a more comfortable and productive environment for customers and employees. The upgrades so significantly reduced our energy costs that our utility company actually called us to see if we had shut down a third of our building.”
The majority of the upgrades to the 310,650-square-foot, 9-story facility were completed to address aging and outdated infrastructure. Officials say the project supports Gov. Terry McAuliffe’s recently released energy plan and his new executive order on reducing energy consumption in state buildings.
Upgrades to the building included replacing all interior and exterior lighting systems with highly efficient illumination. Water retrofits were completed throughout the building to increase energy efficiency and conserve water. Chilled-water system upgrades included installing two new centrifugal chillers, variable-flow drives and deduct meters, which help reduce sewer fees for cooling-tower water.
The project team replaced outdated pneumatic building controls to allow for chiller plant optimization and control of the heating plant, lighting system and other upgrades throughout the building. The team also replaced outdated windows with highly efficient windows for increased energy efficiency for the building.
