Our History
In 1997, three engineers—Dave Ricketts, Marcus Dell, and Brian Hubbs—set out to transform the way buildings are designed and constructed by putting building science at the center of practice. Their vision was to bridge the gap between physics, design, and construction, creating a firm dedicated to making buildings perform better. What began as a small practice in Vancouver has since grown into a North America–wide firm. In 2015, we officially became RDH Building Science Inc.
