Lawson Centre for Sustainability

Construction is well underway for ߲Ƶ’s new mass timber, zero carbon and LEED platinum building that uses geothermal heating and cooling as well as rooftop photovoltaics and an underground cistern for rainwater collection and reuse. The Lawson Centre for Sustainability will provide critical residential, academic and community spaces for the community, and features a rooftop farm and a community kitchen to make sustainability part of daily life at the College.

Bird’s-Eye View of the Construction Site

The solar-powered camera looks westward from Philosopher’s Walk to capture photos of the entire construction site: ߲Ƶ proper is on the left (south); the Gerald Larkin Building is on the far left (along Devonshire Place); the construction zone is in the centre (north field and former parking lot); and the U of T Varsity Centre is on the right (north).
