4100 Harry Hines — Dallas, TX
The 4100 Harry Hines property is a prime example of the firm’s commitment to a new triple bottom line investment strategy … People, Planet and Profit. The building, which offices CDK’s headquarters, was originally built in 1963. Prior to purchase by a venture established by CDK, the building was vacant for five years and was in such a condition of needing repair that many other developers viewed the site as a complete tear down. CDK was determined to save the existing structure and improve the surrounding neighborhood. By implementing the People, Planet, and Profit strategy, benefits of going green were achieved in the following categories.
Site Selection: By saving the existing structure the redevelopment had little to no environmental impact. To help mitigate the building’s heat island effect the use of lighter-colored roofing material and a green roof was installed, which reflect more sunlight and absorb less heat. The green roof is planted with drought-resistant plants and provides an oasis in the sky for the building’s occupants. Located next to a new light rail station qualifies the site as a transit-oriented development. Employees have a choice between bus or rail service to commute to work. This public transit option will reduce employee’s reliance on autos and reduce air pollution. Employee locker rooms with showers and bicycle storage are provided to promote pollution-free transportation. The exterior lighting system is designed to retain 95% of the light on the building’s footprint and emit no light pollution to the surrounding properties. During the demo process 65% of the demolition waste was salvaged or recycled rather than sent to a landfill.
Energy Conservation: 4100 Harry Hines consumes 30% less energy than standard buildings resulting in lowering energy costs for ownership. Energy conservation measures were designed into the renovation. The installation of high-performance windows allows for less heat transfer and results in lower cooling costs. Highly efficient lighting fixtures with occupancy sensor controls and state of the art HVAC equipment where incorporated into the building. The electricity used is generated from 100% renewable sources reducing CO2 emissions, dependence on fossil fuels and producing less air pollution.
Water Conservation: The building was designed to use 50% less water than comparable buildings. Dual-flush toilets and low flow lavatory sinks and shower-heads were installed. The entire site was landscaped with low watering native plants and grass. A rain harvesting system captures the building’s rain runoff in a 30,000 gallon underground cistern for storage and landscape irrigations needs. The condensation produced by the air condition units is captured and then used for site irrigation. No potable water is used for site irrigation. The rain harvesting system also reduces the sites storm water runoff into the city’s already overtaxed system.
Indoor Environmental Quality: The building is filled with a greater percentage of daylight and fresh air than a typical office building. These features create a workplace environment in which the building users are healthier and more satisfied, increasing productivity and lowering absenteeism. The carpet and paint used are all low VOC to avoid the introduction of toxic chemicals in to workspace. Any cleaning solutions used in building maintenance are green labels or better. The new construction materials have a high percentage of recycled content as well as materials that are locally harvested and manufactured thereby decreasing the pollution created by shipping items long distances.
