"In my career as a school superintendent this is my third energy performance contract project. I can say without reservation that ECG's involvement in the current project has made it the smoothest process that I have experienced."

"I can recommend ECG to any school district considering an energy performance contract project. The involvement of this firm in the earliest stages of the energy performance contract process is critical to the ultimate success of the project."
- Dr. Martin D. Handler, Superintendent
