@4240 Building Receives LEED Platinum Certification
@4240, an adaptive reuse project in St. Louis’ Cortex Innovation Community, earned LEED Platinum certification, the highest designation awarded by the U.S. Green Building Council.
HOK’s St. Louis office collaborated with Tarlton Corporation on the design-build project, transforming a former telephone factory into a state-of-the-art lab and research facility while preserving the 1949 building’s historic character.
Wexford Science & Technology commissioned the $73 million project as part of the Cortex Innovation Community, a 200-acre technology district integrated into St. Louis’ historic Central West End and Forest Park Southeast residential neighborhoods.
Adding modern, high-performance systems to the industrial building, the design team cut floor openings into the central portion of the building to allow skylights to bring daylight into a slot courtyard, light wells, the interior areas of the building and a new two-story concourse.
The team also worked within historic guidelines to restore the building’s deteriorating brick skin, add insulation under a new roof and upgrade the industrial windows with historically accurate insulated replacement glazing. The building is now 45 percent more energy efficient than a typical lab/office facility.
Home to Washington University’s Office of Technology Management, @4240 will also house the Cambridge Innovation Center, Boeing’s Ventures discovery unit, Husch Blackwell’s intellectual property and corporate fund formation units, creative agency Manifest Digital, Washington University School of Medicine and yeast producer AB Mauri.
