SDL has practiced sustainable design prior to the standardization of the process through the LEED Rating System for both structural design and site development. SDL has always strived to optimize the design of the structure to maximize structural performance by using the minimum amount of construction materials, by using materials that are locally available, by designing for longevity of service, and by attempting to accommodate anticipated future changes in the building’s use.
Civil Design incorporates environmental sustainability from initial site selection through stormwater best management practices, erosion and sediment control, water conservation and sanitary sewer treatment and disposal.
From a structural perspective, sustainable design concepts include specifying recycled content (reinforcing steel, structural steel and slag as a Portland cement replacement) and specifying materials that are locally available. Structural steel produced in the United States contains at least 93 percent total recycled content. Recycled industrial byproducts, such as fly ash and slag, can be used to offset dependence on raw materials in concrete mixes.
SDL’s Brentwood, Tennessee office achieved the first LEED for Commercial Interiors Certification in the State of Tennessee, and is awarded the Tennessee Green Award by the Tennessee Chapter of the International Interior Design Association. A highly efficient floor plan was developed that allowed for the re-use of 100% of existing workstation furniture, seating, casework, doors, and lighting fixtures from the previous office location. Additional environmentally friendly construction practices were also utilized during this tenant build-out.
