Clark and Grand Hotel Complex in Chicago Achieves LEED-NC Silver Certification

Aloft Entry

The Clark and Grand Hotel Complex in the River North neighborhood recently achieved Leadership in Energy and Environmental Design (LEED) for New Construction (NC) Silver certification from the U.S. Green Building Council.

Clark_Grand_Southeast_FIXDesigned by HOK, this is the first high-rise select service hotel in Chicago made up of three distinct hotel offerings under one roof.

The Clark and Grand Hotel Complex consists of a Hyatt Place, a Fairfield Inn & Suites and an Aloft Hotel offering a total of 664 guest rooms. The complex achieved a 28 percent water use reduction by using low flow plumbing fixtures, in addition to a landscape design that only uses non-potable water for irrigation. The efficient heating and cooling systems reduce energy use by 38 percent, along with an optimized exterior envelope with insulation and a window-to-wall ratio of 38 percent.

As the third new construction LEED-certified hotel project in Chicago, the energy performance of this complex is 38 percent better than a typical hotel in the city. The design team created a high-performance envelope with efficient mechanical systems and controls, which both respond to the increase in perimeter thermal performance.

By maximizing open space through vegetated green roofs, HOK’s design minimizes storm water runoff, reduces the heat island effect, and enhances and restores habitats through the use of native and adaptive plant species. The design incorporates 24.7 percent regional materials and diverted 91.7 percent of the construction and demolition waste.
