Facility Energy Efficiency Studies

Energy Experts employs a systematic approach to document current energy consumption and identify the most practical approach to improve performance.

We have found that mapping facility energy flows using Sankey diagrams can be a particularly useful tool to understand energy consumption and identify potential opportunities. An example of a Sankey energy flow diagram is shown below.

Typically, the study will prioritize and focus on key energy consuming equipment and processes where opportunities for improvement are greatest. This approach allows the study to be tailored to meet specific needs or budget constraints. If a more comprehensive assessment is desired, we recommend an “Integrated Energy Audit”.



Key steps include:
  • Inventory Unit Operations
  • Measure and Map Energy Flows
  • Data Analysis and Integration of Impacts
  • Quantify and Prioritize Opportunities
  • Communicate and Train
