Founded in 2008, Coolearth Architecture is a Toronto-based firm dedicated to designing functional, high-performing, and highly energyefficient buildings. Guided by a mission the firm describes simply and clearly – to create “buildings for human prosperity within a flourishing planet” – Coolearth approaches each project with a focus on balancing aesthetics, functionality, and sustainability. At the helm is Sheena Sharp, principal architect, for whom architecture has always been about more than buildings. It is about responsibility – to people, to communities, and to the planet those buildings will serve for generations. After more than 16 years at a large firm focused primarily on development-driven projects, Sheena sought a more intentional approach to the impact of her work. That personal shift became a professional one as she connected with likeminded collaborators who shared her concern about climate change and the role buildings play within it. While the firm has evolved over time, that original focus – designing buildings that respond intelligently to environmental realities – has remained constant. Today, Coolearth Architecture operates as a fullservice architecture practice, working across design, detailing, and delivery, with a particular depth of expertise in low-emissions and energyefficient buildings. The firm’s size – roughly 10 people – has proven to be a strategic advantage rather than a limitation. By focusing deeply rather than broadly, Coolearth has developed the technical knowledge required to support complex, high-performance projects, often partnering with larger firms to bring that expertise to scale. That depth is increasingly being applied to multiJANUARY 2026
