E3’s leadership team has been working in energy management since the 1980s, building decades of experience that continue to shape how we serve our clients today. That foundation is reflected in the trust placed in us by hundreds of Texas school districts, healthcare systems, and municipalities. With a client list spanning more than 400 public entities and 375 completed projects, E3 has become the partner of choice for organizations seeking lasting solutions.
We know that energy management is more than solving maintenance issues—it’s about creating efficient, comfortable environments that allow our clients to focus on their true mission: serving their communities.
