Testimonials

“As a global manufacturer of building materials, energy is a big expense for us. The slightest fluctuation wreaks havoc on our budgeting and materials prices. We are thankful for your help on our global energy management team and development of our enterprise-wide, real-time energy management program.”

“This project has not only made our buildings more comfortable, the learning experience has improved dramatically and allows us to illustrate renewable energy, energy efficiency and energy management first hand.”

“This was a marquis project, not just for Port Hueneme, but for the entire US Navy. Your “netzero energy” designs will be replicated and adopted across the Navy. Your engineering is certainly industry leading. Thanks.”

“We were really pleased how the company educated us about energy efficiency, explored many options, came up with great “out of the box” solutions, and then walked us through the whole process.”
