Company History

The company began as Energy Squared and later rebranded to reflect a deeper alignment with a national service platform. The early years focused on refrigeration and controls for local commercial buildings. Over time the practice grew to include full MEPR/FP services and energy modeling work tied to sustainability goals.

Growth came from repeat clients in retail, light industrial, and institutional sectors, plus a steady stream of retrofit work as municipalities and building owners sought to reduce energy use in the local climate of hot summers and cold winters.

Leadership

Leadership is made up of licensed engineers and project managers with decades of combined MEPR/FP experience. The founding team has hands-on experience in field investigations, code review, and energy analysis. Leaders are active in regional engineering networks and work with local contractors, architects, and planning boards in Princeton and nearby towns.

Specialties & Highlights

• Single-source MEPR/FP coordination that reduces design conflicts on remodels.
• Focused energy modeling and emissions planning to support decarbonization goals.
• Practical inspection services: electric inspection and plumbing inspection for projects at permitting stage.
