Robert GreenwaldROBERT GREENWALD,
P. Eng., MBA -- Principal and President

Robert Greenwald has a passion for energy management. His unbridled enthusiasm for helping organizations save energy and reduce their environmental impact has served Robert and the firm's clients well since he joined Prism Engineering as a recent graduate of the University of Waterloo in 1991. Four years later he became a principal of the firm and has served as its President since 2005.

"One of the most personally satisfying aspects of working in the energy management sector is looking back on a project and seeing the quantifiable impact we have had on our client's profitability and on the environment. I also love to hear from participants in the workshops we deliver, who share their newfound excitement about improving energy efficiency in their own organizations. In those moments, it becomes very clear that we do make a difference; that we are part of the solution."

-- Robert Greenwald

Over the course of his first two decades in the industry, Robert has conducted hundreds of energy audits, assessed countless energy management opportunities, developed dozens of high-level Energy Management Plans, and facilitated the design, specification and implementation of scores of building retrofits. As well, Robert helped generate Prism's Utility Monitoring and Analysis (PUMA) database to allow businesses and government agencies to better track and tame utility costs. He has also taken on the key role of Energy Coach for several clients to support and sustain their organizational energy management programs.

Robert's excitement for this industry is perhaps most apparent when he is developing and delivering energy management training. Since 2000, he has produced and presented over 200 (and counting) energy management workshops to a variety of commercial and industrial sectors. Robert is proud to have conducted training on behalf of leading organizations and utilities including BC Hydro, BCIT, the Building Owners and Managers Association of BC (BOMA BC), Manitoba Hydro, and NRCan's Office of Energy Efficiency. In 2010, he helped launch BOMA's e-Energy training for Building Operations, an on-line training course which raises energy management awareness among building operations personnel across the country.

Robert holds a Bachelor of Science degree from the University of Waterloo and an MBA from the University of British Columbia. He is also the recipient of numerous awards for his work from the Association of Professional Engineers and Geoscientists of BC (APEGBC), The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and BC Hydro.

Brian O'DonnellBRIAN O'DONNELL,
P.Eng -- Principal and Founder

"Embarking on an energy management program is a lot like going on a diet or exercise program -- commitment to change is required for sustained results and it is human nature to resist change. In order to be successful, energy management must fully engage people in the process. In some ways, getting individuals to understand and embrace the changes being proposed is even more critical to the project than the specific technology or equipment being used. I believe that one of the reasons many of Prism's earliest clients are still with us today including Bentall, Vancity, Austeville Properties, and Air Canada, is because we focus on guiding and helping people through the process, and it provides real value to their organizations."

-- Brian O'Donnell

In 1973, Brian witnessed the crippling effect of the OPEC oil embargo on the Canadian and US economies. It was then he decided to pursue work to help North America strive towards energy independence. Rather than pursuing a career in renewable energy, he determined that he would have the greatest and most immediate impact by focusing on energy efficiency in existing buildings. After completing his degree in Mechanical Engineering at UNB in 1979, Brian travelled to Vancouver and joined BC Hydro's Energy Conservation Division, now known as Power Smart.

In 1981, Brian moved to Toronto where he worked as a project engineer for nine years honing his energy management skills. During that time, he developed an expertise in conducting energy audits, analyzing utility data, monitoring and verification, training building operators and designing and implementing retrofit projects. Keeping his eye on the momentum that BC Hydro was generating out West, Brian saw an opportunity to apply his skill set in providing guidance to the rapidly growing number of early adapters of energy management in BC. To that end, Brian moved back to the West Coast in 1990 and founded Prism Engineering.

Over the last two decades, while energy management has waxed and waned in popularity, Brian has maintained an unwavering focus on improving building energy efficiency and comfort while reducing operational costs. Brian now leads a team of mechanical engineers and designers in finding innovative ways of upgrading building mechanical systems to provide improved reliability and long term performance. His "whole building approach" and talent for the preparation and implementation of master plans for mechanical and electrical system upgrades have proven invaluable to many clients including Department of Fisheries and Oceans, Vancity Savings Credit Union, and Public Works and Government Services Canada.

He is a past president of the local chapters of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the Association of Energy Engineers, and has received numerous ASHRAE and BC Hydro awards.

In his downtime, Brian enjoys spending time with his family and recharging at his weekend getaway. He is also an avid outdoorsman who keeps fit with skiing, hiking, biking, and kayaking.
