Nichols said he took special joy in seeing it come down because it was “not only an ugly parking garage, but a reminder of failure.” Under it were three abandoned fuel tanks, an abandoned water well and contaminated soil and water, all of which was removed.
Nichols ticked off a list of accomplishments contributing to Devon Energy Center's effort to gain gold LEED certification — for Leadership in Energy & Environmental Design — from the U.S. Green Building Council.
Demolition waste
All the material from the parking deck demolition was kept out of landfills.
• 11,200 tons of concrete was recycled and used for erosion control on a lakefront property.
• More than 15,200 tons of concrete went to the Oklahoma Department of Transportation as coarse rock.
• Nearly 500 tons of metal went to recycling centers for miscellaneous use.
• Some 500 light fixtures went to Oklahoma Electrical Supply Co. for reuse.
Construction waste
So far, 93 percent of construction waste has been recycled, a total of 69,026 tons.
• 2,565 tons of concrete.
• 2,485 tons of wood.
• 2,484 tons of metal.
• 1,486 tons of gypsum.
• 6 tons of plastics.
Building performance
“Green” features are built into building operations.
• District cooling and state-of-the-art energy management technologies maximize efficiency.
• The geometry of the tower and exterior glass fins reduce solar load.
• Energy-efficient light fixtures use minimal energy to operate.
• Light fixtures dim automatically depending on available natural light.
• Sensors dim lights when space is not occupied.
• Raised-floor air distribution increases efficiency and contributes to indoor air quality.
• The tower's geometry and glass walls allow abundant natural light in all areas.
