The four-story, 7,200-square-meter (77,500-sq.-ft.) Greenstone Building is a model for sustainable development north of 60. Designed as a LEED® project, this home for 200 public servants takes maximum advantage of daylight during both the short winter days and long summer days.
Greenstone houses the second largest commercial building photovoltaic system in the world. A south-facing atrium acts as a winter room, not only to maximize snowy views in this chilly city but to enhance the thermal performance of the building. Facing Franklin Avenue, Greenstone has a strong civic presence, creating a clear and transparent public entry on the main street of Yellowknife.
One of PCL's goals was to help this project achieve additional LEED points. Thought turned to reality when PCL turned a groundwater problem into a water collection success, opting to fill holding tanks and flush all urinals and toilets with 100% groundwater. This initiative, along with a close working relationship with Manasc Issac Architets, helped the Greenstone Building achieve LEED Gold.
