Bus garage puts the brakes on poor IAQ with ERV, air curtains
Although it’s only 25% complete, the Central Ohio Transit Authority’s (COTA) ongoing $75 million conversion to compressed natural gas (CNG) fueled buses is already saving more than 2.5 million gallons of diesel fuel and emitting 100 tons less bus emission contaminants annually in the greater Columbus, Ohio, area.
The bus conversion project is accompanying an HVAC retrofit of the 400,000-sq-ft CNG bus maintenance and garage areas into an energy-saving showcase that will preserve the environment and help COTA reach its future LEED silver goal.
