One Dallas Center, also known as Patriot Tower, was originally designed by I.M. Pei & Partners in 1979, but over the years became financially bankrupt and left vacant. HKS decided to make their new home in the lower seven floors of the 30 story tower and concentrate their Dallas operations out of the urban core. HKS opted not to construct a new building on a greenfield site in the suburbs, but rather to redevelop an existing tower and help revitalize the downtown area. Located at 350 North Saint Paul Street, the tower has immediate access to the Dallas Area Rapid Transit (DART) system and 30 percent of the firm’s employees make use of public transportation. One Dallas Center was recently awarded LEED Platinum Commercial Interiors (CI) v2009 rating system certification and is also a pilot project for LEED v4.

“As one of the first pilot projects for LEED v4, the city and the nation will be looking to HKS for our firsthand experience with the new rating system,” says Kirk Teske, AIA, LEED AP BD+C, chief sustainability officer for HKS. “One Dallas Center is the epitome of adaptive reuse. We believe transforming this distressed, 90 percent-vacant property into a valuable asset for the city of Dallas will encourage redevelopment in the area and allow the mixed-use building to remain viable for another 30 years.”

To achieve LEED Platinum, HKS incorporated high efficiency lighting strategies, including daylighting, LED lighting technology, sensors and controls and window shading systems to achieve a Lighting Power Density (LPD) of 0.6 Watts/square foot (40 percent below code). The lighting design and control systems alone should reduce energy use by 10 percent. The HVAC system includes a new Variable Air Volume (VAV) HVAC system is paired with a new base building high-performance York chiller. Measurement, verification and commissioning will help ensure the system is working optimally. Low flow plumbing fixtures reduce water use by 40 percent and a rooftop deck and garden provides space for employees to get outside. Materials were selected for sustainability, air quality, and proximity and ongoing recycling, green energy purchasing and management practices will continue the firm’s commitment to reducing their impact.
