This design for a 44-storey tower at 880 Bay Street, within the Queen’s Park government precinct, is a substantial new addition to the provincial government’s Toronto Accommodation Plan. Each facade of the tower has a unique design in order to achieve optimal solar orientation as part of an overall sustainability strategy targeting a minimum of LEED Gold. The building’s long, thin form creates narrow floor plates that optimize natural light penetration. Daylight harvesting occurs on the south face through light shelves inside and brise-soleils outside; glazing on the north face  maximizes natural daylight penetration. Vertical fins reduce glare on the east facade, and fritted glass is placed on the west facade to screen the offices from solar gain. At street level, the building base relates to the scale of the adjacent two-storey arcades of the existing Queen’s Park complex, creating a seamless pedestrian experience  within the precinct.
