Research Drive Parking Garage at Duke University
Research Drive Parking Garage at Duke University
What makes this parking garage on Duke University's campus unique is that it is the first, free-standing, single-use parking structure certified by the U.S. Green Building Council in the U.S., earning 31 LEED® points.
For this precedent-setting project, the university chose Ratio Architects and Walker Parking Consultants to design the 1,917 spaces sustainable parking garage within the research zone of the medical campus. The Ratio/Walker team's design enlightened the USGBC and other sustainable design advocates about the benefits of adding freestanding garages to the list of LEED-certifiable structures.
An important element of the sustainable green design is the architectural context of this garage. The neutral color of the precast concrete panels reduces the heat island effect and blends well with the surrounding buildings on campus. The precast concrete spandrels and column covers provide a monolithic color at a distance while the medium-sandblast finish allows the red stone aggregate to provide a mix of color close up. The mixture of precast concrete spandrels and the natural terracotta and stone material at the lower levels provides a unique design solution, which gives the façade a variety of textures and colors to reduce the scale of the building.
The precast column covers provide a vertical element to the façade while concealing the concrete columns. Reveals in the precast provide a more human scale and align with the curtainwall mullions and tile joints. The structure also incorporates planted trellises on the exterior walls and the roof canopies to soften the garage aesthetic.
At the time of construction, several new building projects in the area eliminated surface parking and, necessitated the construction of a new facility to provide parking to students, faculty, visitors and patients. Garage visitors are educated about sustainable design through learning centers in the elevator lobbies.
