Morrison Residence Hall at the University of North Carolina at Chapel Hill has won the U.S. Environmental Protection Agency’s first National Building Competition, followed closely by a Sears store in Glen Burnie, Maryland, and a JCPenney store in Orange, California.
Here’s why UNC took the top slot. Morrison Residence Hall reduced its energy use by 35.7 percent in one year, saved more than $250,000 on energy bills and reduced more than 730 metric tons of greenhouse gas (GHG) emissions.
The residence hall reduced its energy use through a combination of energy efficiency strategies, including improved operations and maintenance as well as outreach to dormitory residents. A computer touch-screen monitor in the dormitory’s lobby helped Morrison residents and the UNC energy team to keep track of energy consumption. The hall also made improvements to the heating, ventilation and air conditioning system, as well as lighting to help increase energy efficiency.
A Sears store in Glen Burnie, Maryland, came in second place with a 31.7 percent energy reduction, and a JCPenney store in Orange, California, claimed third place with energy savings of 28.4 percent.
Together, the fourteen competitors reduced their energy use by more than 44 million kBtu, saved more than $950,000 in utility bills, and prevented nearly 5,000 metric tons of GHG emissions.
The National Building Competition measured energy reductions from September 1, 2009, through August 31, 2010. The energy use of each building was monitored through EPA’s Energy Star online energy measurement and tracking tool, Portfolio Manager.
The winner is the building with the greatest percentage-based reduction in weather normalized, energy use intensity. Third-party utility statements were required to verify the energy performance of each building.
