Engineered Alternatives

What Engineered Alternatives does

Engineered Alternatives, LLC is an independent energy engineering consultancy founded in 2006 and headquartered in West Simsbury, Connecticut. The firm provides a portfolio of six integrated services for non-residential building systems: ASHRAE Level II and III energy audits, project development support (scoping, engineering analysis, cost estimation), energy-efficient HVAC design-build delivered through partner contractors, technical and financial evaluations of performance contracts, long-range energy master plans for campus clients, and sustainability program coordination. The work follows ASHRAE standards and draws on staff expertise in energy codes, chiller plant analysis, retrocommissioning, and electrical/lighting design.

The firm's customer base spans hospitals and healthcare systems (Baystate Medical Center, Mercy Medical Center, Dana-Farber Cancer Institute), state and municipal governments (State of Connecticut, Town of West Hartford, City of Bristol, Scott County Public Buildings), K-12 and higher education institutions (Milton Academy, Avon Old Farms School, University of Richmond, Torrington Middle School, Ellington High School), commercial real estate, non-profits, and — notably — energy service companies and contractors (Siemens Industry, Honeywell Building Solutions, Comfort Systems USA Energy Services, Eneractive Solutions, The Eugene Steinberg Company) that subcontract the firm's engineering expertise. Geographic reach spans Connecticut, Massachusetts, and Virginia.

Revenue is generated through project-based professional services engagements with custom pricing based on scope, audit level, and client requirements, with multi-year contracts typical for larger campus and municipal relationships. The firm is founder-led by President John P. Hennessey, P.E., with a six-person technical team including Senior Energy Engineer Thomas P. Wutka, who was instrumental in the development of ASHRAE Standard 90.1. The firm operates as a privately held LLC with no external institutional investment, no disclosed revenue or growth metrics, and no digital/online presence beyond a basic company website — distribution relies on referral networks, case study reputation, and long-tenured client relationships rather than active marketing channels.
