Circadia Group Inc. has opened newly renovated North-East Regional Headquarters at 2265 Route 33 in Hamilton Township. Township and Circadia officials held a ribbon cutting on November 7.
The company develops, manages, and implements comprehensive, campus-wide programs that support clients in achieving their decarbonization goals. Founded in 2018 by Brian Robertson, who previously led the successful conversion of Princeton University’s campus lighting to LED, the company has grown into an owner’s representative firm overseeing more than $500 million in energy-conservation projects.
The company’s new facility, a transformed former bank building, has been redesigned into an energy-efficient, collaborative workspace that fosters teamwork among vendors, staff, and regional clients. The modernized space reflects Circadia Group’s commitment to sustainable design, innovation, and operational excellence.
Robertson expressed gratitude to the many contributors on his team who brought the project to life, including Janisak Biddle Architects, J&M Consulting Engineers, and Irwin & Leighton, Inc.
“This new headquarters represents more than just a building — it’s a symbol of progress, partnership, and purpose,” he said. “We’re excited to continue growing here in Hamilton Township and look forward to many years of collaboration and innovation.”
Mayor Jeff Martin welcomed the company’s expansion into Hamilton, noting the alignment between Circadia’s mission and the Township’s long-term vision.
“Circadia Group’s commitment to sustainability and forward-thinking energy solutions makes them a perfect fit for Hamilton,” said Mayor Jeff Martin. “We are proud to welcome a company that not only invests in our community, but also helps institutions across the region build a cleaner, greener future. We look forward to supporting their continued growth and success right here in our township.”
