Three universities partnered to create the Collaborative Life Sciences Building (CLSB) and Skourtes Tower, a new allied health, academic and research building located on a brownfield site. An innovative model of interdisciplinary health sciences education, research and education, CLSB incorporates numerous sustainable design innovations, including eco-roofs, non-potable water storage for toilet flushing, atrium heat recovery and low ventilation fume hoods. Innovative material re-use included salvaging oil drilling pipes for use as foundation piles. The building is predicted to have 45% energy savings thanks in part to its thin profile that allows the labs to get daylighting from two sides.

Despite a challenging site for a complex university facility, the designers created a building that engages not only three university clients but also a variety of patients in an inviting fashion. To focus on rigorous sustainability with multiple stakeholders is challenging without clear leadership from the design team, and it’s obvious the design leadership had to follow through on clearly identified priorities, but this project demonstrates that even a large building with a complex program can achieve high performance. This building has a remarkable 67% of its occupants able to use public transit, cycling or walking to access the site, and it houses 400 bike parking spaces. Like the other winners this year it seems to buck the trend of over-glazed large buildings. The façade thoughtfully handles solar control and daylight harvesting.


  • Estimated % of occupants using public transit/cycling/walking: 67%
  • Daylighting at levels that allow lights to be off before nightfall: 55%
  • Lighting power density (watts per square-foot): 0.60 watts/sq.ft.
  • Outdoor views: 80%
  • Reduction of regulated potable water: 62%
  • Total EUI (kBtu per square-foot per year): 110
  • Net EUI (kBtu per square-foot per year): 110
  • Percent reduction from National Median EUI for Building Type: 45%
