Sustainable Design




The firm’s sustainability outlook begins with the belief that the most responsible buildings are designed to endure, adapt, and operate efficiently over time. This approach is evident in projects such as the Ontario Secondary School Teachers’ Federation Headquarters, where structural mass timber, generous daylighting, and an efficient building form are combined to reduce embodied carbon and operational energy use while supporting occupant health and long-term flexibility. Designed to target high-performance environmental standards and net-zero carbon, the project demonstrates how careful material selection, passive strategies, and systems integration can deliver environmental responsibility alongside architectural clarity and workplace well-being.
