What Global Facility Solutions does

Global Facility Solutions (GFS) is a U.S.-based energy and engineering consulting firm founded in 2006 by Robert K. Calloway and headquartered in Columbia, Maryland. The firm delivers MEP (mechanical, electrical, plumbing) engineering design, building commissioning and retro-commissioning, and sustainability services — including ENERGY STAR certification, LEED consulting, BEPS benchmarking, and the proprietary Energy Advisor Program — to commercial real estate portfolios, healthcare facilities, industrial plants, educational institutions, and federal/state government clients nationwide. Core offerings are organized around three pillars (Energy & Engineering Solutions, Commissioning & Retro-Commissioning, Sustainability Services) supplemented by add-on tools such as a proprietary Benchmarking Standards Database covering 50+ U.S. jurisdictions and the BGE Building Performance Tune-Up Program delivered under approved-contractor status.

GFS operates a vendor-agnostic, project-based professional services model: engagements originate through direct outreach and referrals (over 90% of new clients come from referrals) and are scoped into fixed proposals. Revenue is generated per engagement rather than via subscription, with utility incentive program participation (BGE, Pepco, DelMarva Power) acting as a key channel and demand catalyst. GFS holds three consecutive EPA ENERGY STAR Partner of the Year awards (2022, 2023, and the 2024 Sustained Excellence Award) and is an AABC Commissioning Group and USGBC member firm. Since September 2023, GFS has operated as a subsidiary of Exigent, a Huron Capital portfolio company, with management retained and the firm pursuing nationwide expansion through both organic project wins and potential inorganic roll-ups under the Exigent platform.
