RDH Building Science is a consulting and engineering firm with 11 locations across North America, dedicated to delivering climate-resilient solutions for the built environment. As 80% of the buildings that will exist in 2050 are already in place today, we focus on reducing carbon emissions and enhancing building performance through our expertise in building enclosure consulting, energy modeling, and sustainable engineering. Our services include developing comprehensive building retrofit plans and assisting design teams in executing deep energy retrofits.

We specialize in deep energy retrofits, repairs, renovations, and preserving heritage and historical buildings. By integrating sustainability and building science with architectural restoration, we work to safeguard Canada’s built heritage. Our range of services extends from building enclosure and energy consulting to modular construction, capital improvement projects, and research and development, all grounded in science-based solutions that prioritize durability, performance, and climate resilience.

Led by exceptional technical teams in Toronto and Waterloo, we provide tailored strategies to create low-carbon, energy-efficient buildings that address today’s challenges while supporting the needs of tomorrow.
