Prism Engineering first opened its doors in 1990–back in the days before the terms LEED buildings, carbon taxes, global warming and cleantech investments were part of the energy management lexicon.

From the very beginning of our journey, we focused on finding ways to improve efficiency in their buildings and operations and changing the “energy use culture” within their organizations. Three decades later, with the growing urgency to address climate change, our work of helping organizations lead the way to a more sustainable future has never been more relevant or important.

The case studies or projects presented on this website highlight some of Prism’s achievements over our company’s history. Each piece helps tell the story of our consulting firm, which is increasingly focused on changing systems for a better world.

The clients featured are only a sampling of the organizations and businesses with whom we have forged mutually beneficial relationships. Whether the partnership has lasted 30 years or 3 months, we are very grateful to all our clients who have entrusted their energy management, mechanical, electrical, and sustainability consulting needs to us.

To every organization we have had the pleasure to serve, we would like to say “thank you” and that we are proud to have played our part in helping your organization with new technologies and approaches to meet your carbon reduction targets. We look forward to continuing to work together.

“One of the most personally satisfying aspects of working in the energy management sector is looking back on projects and seeing the quantifiable impact we have had on our clients’ organizations and the environment. Equally rewarding has been hearing the feedback we receive from clients, who share with us their new-found passion and excitement for energy management. In those moments, it becomes very clear that we do make a difference, that we are part of the solution.”
Robert Greenwald, Principal and President
