Xnergy opened its doors in 2001 with D. Jason Davis and Joey Patalano as two of the original partners. The company has evolved from a General Contractor (GC) to an Engineering, Procurement, and Construction (EPC) provider to Construction Management (CM) leader. Since inception, they've facilitated the success of the company and pioneered energy and construction management methods and services that have saved millions of kilowatt-hours and dollars. In 2017, they re-branded Xnergy and continue to offer traditional construction management services and EPC services for any scope of work. We specialize in complex projects encompassing multiple trades and disciplines such as electrical, HVAC, process piping, and associated engineering.
