Weaver Cooke Construction has made a commitment to becoming an industry leader in sustainable construction, so when it came time to build their own office building they decided they had to “walk the walk,” choosing to build according to Leadership in Energy and Environmental Design (LEED) guidelines.

For a number of reasons, a concrete structure helps to meet LEED guidelines. Wendy Cockerham, Weaver Cooke’s director of sustainable construction, says the company specializes in preconstruction and construction management. They’ve constructed several concrete buildings and for their own 15,000 square foot office they decided on tilt-up concrete, hiring Ace Avant Concrete Construction, Archdale, N.C., for the concrete work. Drew Davis, Ace Avant project manager, said meeting LEED requirements caused very little change in their work methods. “We submitted a list of materials that qualified with LEED as recycled materials such as rebar, polystyrene foam insulation, and fly ash. We also sorted waste such as concrete, stone, and concrete block into separate containers for recycling.”

Tilt-up construction earned LEED points too because the walls don’t leak air and the concrete has thermal mass benefits. The contractor also installed 3-inch-thick rigid foam insulation on the walls.

According to Cockerham, the features in the building design and construction that will help them gain LEED points are:

  • Tilt-up construction provides an energy-efficient building envelope
  • Concrete is produced locally, within 500 miles of the jobsite
  • The building is designed with abundant natural lighting
  • Low VOC building materials maintain high indoor air quality
  • High recycled content building materials were used
  • Water saving devices will save 50% of water usage in the building
  • There was minimal land clearing— much of the land and trees were left in their natural state.
