The Crosstown Concourse, a mixed-use high-rise building in Memphis, Tennessee, has just become the world’s largest building to be awarded Leadership in Energy and Environmental Design (LEED) Platinum certification for historic adaptive reuse, according to the architect who worked on the project, says Commercial Appeal.
“Through extensive research regarding Crosstown Concourse’s size and scope, we believe this correctly qualifies the title as the largest historic adaptive reuse LEED Building Design + Construction Platinum project in the world,” Tony Pellicciotti, principal at Looney Ricks Kiss (LRK) architects, Memphis, says.
The 1.1 million-square-foot former Sears distribution center was reopened in August after undergoing extensive renovations that favored more sustainable building solutions. The mixed-use facility is now home to 267 residential apartments and roughly 40 commercial and nonprofit tenants, including a high school and various stores and restaurants.
"It starts with the whole concept of reusing the building,'' Pellicciotti says in the report. "Everything about the site is sustainable starting from the density. It’s hard to argue about the density of Crosstown,'' he said in reference to the volume of tenants now occupying the space.
Recycling also played a prominent role in helping the building achieve LEED Platinum certification. Pellicciotti says that they recycled more than 65 million pounds of material, which was 94 percent of all waste produced during the construction and demolition process.
Much of this recycled material came in the form of concrete, which was carved out of the existing structure to create more open spaces. The resulting rubble was then crushed and reused as base material for road building.
"To me, the piece I'm most proud of is we did not spend a single dollar not consistent with the (Crosstown Concourse) program,'' Pellicciotti says. "We did not do stuff to buy LEED points.''
“We believe inherently in sustainable design at the highest level, no matter the scorecard,'' Pellicciotti continues. "Every single collaborative decision we made stemmed from our innate goal to advance the mission of this transformative project.”
