What SynEnergy does

SynEnergy LLC is a Denver-headquartered MEP (mechanical, electrical, and plumbing) engineering design firm founded in 2011 by CEO Mina McCullom. The firm delivers five core service modules — mechanical engineering, electrical engineering, plumbing engineering, building information modeling (BIM/VDC), and CFD/energy analysis — integrated under a single practice. Its technology stack combines computational fluid dynamics simulation with DOE2 hourly-simulated energy modeling in EnergyPlus and eQUEST, calibrated to ASHRAE guidelines within ±10% of utility bills, and runs an 8-step Revit-based BIM methodology for clash detection across disciplines. SynEnergy wraps these capabilities with a financial life cycle cost analysis layer that translates energy modeling outputs into capital-versus-operations cost comparisons for clients.

SynEnergy serves federal, municipal, aviation, higher education, industrial, multifamily, and commercial clients across the United States, with project sites spanning Colorado, California, North Carolina, and federal assets nationwide. Marquee engagements include the $770M Great Hall Renovation at Denver International Airport, MEP QA/QC on terminal concourse expansions ($700M, $560M, $550M), the $45M American Express Centurion Lounge at DEN, and a 5-year $150M IDIQ contract with the US Army Corps of Engineers for mechanical and electrical assessments. The firm is certified as a WOSB, EDWOSB, SDB, MBE/WBE/SBE, and DBE across Colorado, Washington, New York, and the New Jersey Port Authority — certifications that provide direct access to federal, state, and municipal set-aside contracting vehicles.

The business operates as a project-based professional services firm. Revenue is generated through consulting fees on engagements ranging from small assessments under $1M to mega-project MEP QA/QC work above $700M, delivered via IDIQ contracts, on-call service agreements, and direct project awards. Distribution is direct enterprise field sales — primarily through IDIQ vehicles and relationship-driven business development led by a Director of Business Development with prior USACE District Commander experience. Pricing is per-project and is not publicly tiered; contracts are typically multi-year. The firm is privately held with no institutional investors or parent company identified.

Core offering

SynEnergy provides MEP (Mechanical, Electrical, Plumbing) engineering design services for buildings, integrated with computational fluid dynamics analysis, whole-building energy modeling (EnergyPlus and eQUEST), and financial life cycle cost analysis. The firm delivers design, analysis, BIM/VDC, and construction administration support across aviation, federal, municipal, higher education, industrial, multifamily, and commercial projects ranging from small tenant finish-outs to mega-projects valued at $770M+.

Product overview

SynEnergy is an MEP (Mechanical, Electrical, Plumbing) engineering design firm offering five integrated service modules. The core services are Mechanical Engineering, Electrical Engineering, and Plumbing Engineering, which form the foundation of building systems design. Building Information Modeling (BIM) provides 3D visualization and clash detection across all engineering disciplines. CFD & Energy Analysis complements the design services with computational fluid dynamics simulations and energy modeling tools (EnergyPlus and eQUEST) to optimize ventilation and predict energy performance. The firm integrates these services to combine MEP design with energy and financial life cycle cost analysis.
