Then and Now

Prism was founded in 1990 by Brian O’Donnell who saw an opportunity to bring Energy Management and existing building upgrades at the start of the first BC Hydro Power Smart program.

Robert Greenwald joined the firm in 1991 and became President in 2006. Under Brian and Robert’s leadership, Prism has grown from a small handful of engineers to a company of over forty-five engineers, designers, and sustainability professionals, passionate about making a difference. We are proud to still be working with many of our clients who have been with us since our early years. We continue to work with passionate people across all sectors who share our vision for reducing environmental impact through technology, people and organizational change.

Looking toward the future

Now nearing three decades in business, we have transitioned our leadership to give additional transparency and clarity to the roles, and to further build resilience into our company. Going forward, Brian will continue to play a key role in our Account Management and Client Relationships efforts.

We are pleased to introduce to you our Leadership Team, many of whom have been a part of Prism for many years and have been instrumental in stewarding our work and deepening our impact. Prism’s Principals provide strategic vision and leadership for the company. Associates have specialized knowledge and provide mentorship for key aspects of the company to ensure that we continue to deliver quality services to our clients.

Our commitment

As we move into the next decade, energy management and sustainability and reducing our environmental footprint are more important than ever. We are inspired by recent developments in addressing climate change. In addition to reducing waste and improving efficiencies, we are expanding our design services to include the low carbon systems and applying renewables to offset energy use. We are also increasing our efforts to help organizations adapt to climate change and build resilient systems.

Part of a growing community

We are incredibly grateful to our staff who make Prism’s mission come to life. We value being a workplace that is fast-paced and highly collaborative with hundreds of projects on the go at any one time. Our staff is hard-working and motivated to continually strive for better, whether researching the latest technologies or helping mentor co-op students as future innovators.

We are also thankful to all of the people who we have had the pleasure of working with along the way–from the elementary school students who participate in ‘Lights off Lunches’ to the building operators learning how to optimize digital controls systems. And from the Property Managers upgrading their building systems to the Energy Managers developing strategic programs for energy management at a mine site.

We are excited about the future. Stay tuned.
