Located in beautiful Honolulu, Hawaii, the Punahou School, Grades 2 to 5 Neighborhood Classrooms and Learning Commons project embodies Punahou’s educational philosophy by incorporating sustainable elements that foster a direct connection between learning and the environment. Nordic PCL incorporated interactive sustainability features such as Plexiglas floor troughs and living walls in the stairwells (both feed into a rainwater catchment system that can be used for irrigation) and recycled materials from the building. The classrooms incorporate natural lighting and ventilation, with a private learning garden for each class. Built to the highest standards of green building and design, the second phase of this project is set to achieve LEED Platinum and Hi-CHPS certification and will reach completion in mid-2019. The project team received the 2018 NAIOP Kukulu Hale Sustainability Development Award for completing first phase of the project, comprised of four classroom buildings. The award recognized the team’s exceptional work on this creative and collaborative school.
2. Edmonton Tower
The 27-story LEED Gold Edmonton Tower is sustainable and architecturally progressive with a contemporary design. During construction, 25 percent of materials used were recycled or contained recycled content, 20 percent of material was from local sources, and 91 percent of construction debris was diverted from landfill. The sustainable efforts did not end with construction as innovative strategies were incorporated into the tower’s design to ensure optimal sustainability during operation and maintenance. The strategies include the following:
- Reduction of energy cost for heating and cooling through advanced, high-efficiency mechanical equipment, high thermal insulation and passive design strategies.
- Reduction of process energy from lighting and equipment through daylight harvesting, occupancy sensors, lighting controls, refrigeration heat recovery system, etc.
- An overall energy intensity target of 110 kWh/m2/yr. (one-third that of a typical Edmonton building).
- Halogen-free electrical equipment and low-mercury lighting.
3. Okanagan College Trades Complex
The Okanagan College Trades Complex is a world-class facility dedicated to inspiring the college’s trades programs to think sustainably. The PCL team retrofitted the existing building (a green building practice that substantially reduces waste and increases energy efficiency), and added 6,024 square metres of new space. To add to the college’s impressive sustainable campus (which includes the Jim Pattison Centre of Excellence), the Trades Complex has achieved LEED Platinum certification.
4. Factoria Recycling and Transfer Station
The Factoria Recycling and Transfer station in Bellevue, Washington, is a LEED Gold certified waste facility that uses 40 percent less energy than other facilities of its kind. Contributing to the sustainability of the building are a rainwater harvesting system that reduces water use by 59 percent, locally sourced recycled construction materials, and translucent wall panels which bathe the facility in natural light. The facility also diverts 5,000 tons of waste from landfill annually.
