Overview

At Ark Energy, we prioritize measurement integrity and transparent reporting in every energy efficiency project. One of the key areas where our analytics team has added measurable value is the treatment of Non-Routine Adjustments (NRAs). NRAs external changes unrelated to retrofit works often skew energy savings results if not properly addressed. To ensure our savings assessments reflect actual performance improvements, we developed a dedicated NRA Analytics Tool that enhances the reliability of our M&V reporting across diverse projects and sectors.
 

Challenge

In performance-based energy contracts, savings are often overstated due to unaccounted-for NRAs— uch as operational schedule changes, tenant variations, or external disruptions. Our client needed a solution that could accurately isolate retrofit-driven savings and avoid inflated results that could mislead stakeholders and overcompensate ESCOs. With projects spanning commercial, residential, and industrial sectors, addressing this consistently and at scale was critical.
 

Solution

Ark Energy responded by deploying a custom NRA Analytics Tool capable of identifying, quantifying, and correcting for NRAs across different projects. Leveraging statistical modeling and operational data inputs, the tool flags non-routine patterns and applies calibrated adjustments to ensure baseline alignment.

We implemented this tool across 11 projects covering various sectors, allowing our teams to refine M&V calculations and ensure savings attribution was fair and performance-based.


 

Conclusion

The deployment of the NRA Analytics Tool helped in the following:
 

• Reducing NRA-related distortions by 30%, leading to more accurate measurement of retrofit-driven energy savings

• Enhancing the reliability of savings calculations, ensuring reported performance aligns with actual retrofit outcomes

• Improving transparency and trust between clients and ESCOs by minimizing the risk of inflated savings

• Supporting informed decision-making through more credible M&V results across commercial, residential, and industrial projects
