Whether dealing with mechanical or electrical systems, our team digs down into the details and gathers data to generate a solid plan for energy and carbon savings. Our audits will identify energy and cost saving opportunities, evaluate options for upgrades and, ultimately, provide actionable recommendations for implementation.

Prism is intimately familiar with building systems including heating, ventilation, cooling, and control systems, as well as building envelope and renewable energy systems. On the electrical side, Prism will “light the way” by providing recommendations on lighting systems to reduce maintenance costs, improve visual comfort for occupants, and save energy. Considerations for electrical distribution upgrades that may be required for some mechanical measures are also considered as part of our audits. Our comprehensive approach includes a thorough review of facility operation and a detailed evaluation of energy conservation and carbon reduction measures.

Our offering ranges from high-level opportunity assessments, to walkthrough audits, to detailed energy audits with “investment grade” analysis, to deep retrofit studies.

The chart below compares the key characteristics of our energy audits.


The following diagram outlines the 6-step approach Prism follows when conducting energy audits.
This follows our philosophy of “Reduce, Avoid and Replace.”


A summary of our energy audit process:

  • Meet with the client team to understand the project needs and current challenges
  • Collect and analyze site data
  • Work closely with site personnel onsite to understand systems and challenges
  • Carry out energy analytics
  • Investigate equipment operation including controls review
  • Build an inventory and an understanding of equipment operation
  • Identify technically feasible energy reduction opportunities
  • Evaluate opportunities for conservation, efficiency, and optimization of energy supply
  • Coordinate utility and government incentive applications
  • Prepare a report clearly summarizing the opportunities, financials, and recommended next steps for implementation
