We’re proud to share that HHA's Ontario Power Generation Headquarters project has been recognized for excellence at the Ontario Engineering Project Awards (OEPA)—a program that celebrates the very best in engineering innovation, complexity, and impact across the province.
This project set out to bring Ontario Power Generation's teams together in a single, modern workplace while breathing new life into a landmark site through the adaptive reuse of the former GM headquarters. The result is a highly efficient, collaborative environment designed with long-term sustainability at its core.
HH Angus played a pivotal role as mechanical and electrical engineers, IMIT and lighting consultants, owner’s engineer, plumbing/fire protection/life safety designer, and commissioning authority. Working within an accelerated schedule, fixed budget, and increased occupancy demands, the team delivered forward-thinking solutions—from dual-function HVAC systems and high-efficiency heat pumps to ice storage and advanced energy recovery strategies.
Congratulations and thank you to our client, Ontario Power Generation, for your vision and collaboration, and to our project partners and dedicated team members who made this achievement possible. This recognition reflects what’s possible when strong partnerships and thoughtful engineering come together to create meaningful, sustainable impact.
