— Officials with the City of Indianapolis recently announced that the City-County Building earned the prestigious Environmental Protection Agency's Energy Star certification.
To qualify for the Energy Star, the facility must be more energy efficient than at least 75 percent of similar buildings nationwide. Energy-efficiency retrofits completed over the past year on the 50-year-old, 731,000-square-foot building reduced costs for taxpayers and helped qualify it for the recognition, making it a model for green building in Indianapolis.
"Receiving the Energy Star recognition emphasizes the savings taxpayers are receiving from these retrofits annually in addition to the reduction of our environmental footprint," Mayor Greg Ballard said in a press release. "The city is leading by example in demonstrating to local businesses the benefits of energy efficiency upgrades."
Performance Services, an Indianapolis design-build engineering company, led the design of the retrofits completed over the past year. The Energy Star energy performance scale accounts for differences in operating conditions, regional weather data, and other important considerations. With the recent improvements, the City-County Building has guaranteed $750,000 in annual savings for the next 15 years.
The improvements within the CCB include: heating, cooling, and ventilation system improvements; expanded building controls; lighting occupancy sensors; installation of renewable energy with a geothermal heat-recovery chiller system and solar thermal and solar PV systems; and solar and wind powered LED plaza lights.
