Our Process
Our Proprietary Energy Optimization Protocol

Energy Mapping
A complete analysis of your facility detailing where energy is used and how much it costs. With this information we know where best to focus our efforts to optimize savings.

Solutions Application
Applies our experience and innovation to optimize your current system, providing you a sustainable solution which continues to save year after year. We specialize in delivering low to no capital solutions.

Procurement Analysis
A comprehensive look at how you purchase energy (gas, electric, water, fuel oil, etc.) and how to reduce the unit cost of each energy source. At the completion of our procurement analysis and implementation, you will be procuring your energy at its lowest possible cost.

Validation
Incorporates the U.S. Department of Energy’s tools to confirm the energy cost savings we achieve and to validate savings seen on your energy bills.

Loss Analysis
Utilizes our proprietary tools to determine every energy loss point of your facility and what control, design, and maintenance changes must be initiated to optimize performance.

Sustainment
The processes and procedures implemented with your team to ensure your equipment performs at peak efficiency over time. We are focused on eliminating your energy losses permanently.
