C.K.Choi Building

Institute of Asian Research

The C.K. Choi Building, designed by Matsuzaki-Wright Architects, is located at the University of British Columbia in Vancouver and was completed in 1995. The Choi Building implemented sustainable design practices throughout its development, including the reuse of on-site building materials, natural ventilation and lighting, and rainwater storage for irrigation purposes.

Water resources were further conserved with Clivus composting toilets and a greywater system. Twelve Clivus toilet fixtures, which are located on all three of the Choi Building’s occupied levels and connect with five composting units in the basement, save nearly 100,000 gallons of water per year. Greywater in the Choi Building is used to irrigate the surrounding landscaping.
