Businesses today rely on up-to-the-minute information to support fast and accurate data-driven decision-making, and modern software technology is now making it possible to do the same in the measurement of energy efficiency savings. Optix Quantify, which enables this measure-as-you-go approach, does this by using proven EM&V methodologies to continuously and automatically analyze savings.
Optix Quantify employs open industry standards, such as IPMVP Option C and ASHRAE Guideline 14-2002, and best practices in data cleaning and outlier detection, to build models of energy usage for each premises treated by a program. The predictions of usage from these models are then compared with the actual usage data—AMI or monthly— to assess the realized savings for each project.
Optix Quantify aggregates results across a series of projects to identify the signal in noisy usage data and also compares groups of treated and untreated premises to detect biases and influences beyond the DSM program. With the passage of time, new projects and usage data are added in to Optix Quantify. The result is a rolling assessment of program savings, one that is continually refined as more information becomes available.
Identifies Leading Indicators of Performance
By measuring program performance continuously beginning with the first completed project, Optix Quantify provides utilities, their implementation partners and trade allies with the speed, agility, and insights to make better decisions and meet energy savings targets. Quantify provides utilities with leading indicators of program performance to identify issues and take action long before a formal evaluation.
Actionable Data for all Stakeholders
Real-world savings data provides the basis for a shared view of program performance that is maintained and used by the program, but audited, verified, and analyzed by evaluators. By bringing program stakeholders together around a shared view of program performance, Optix Quantify helps programs move from disagreement over savings to action to identify and address issues.
Complements Traditional Evaluation
Just as accounting software doesn’t replace financial auditing, Optix Quantify doesn’t replace an independent evaluation. A measure-as-you-go approach brings evaluators, program planners, and program implementers together, enabling better and faster decision-making.
Transparency for the Market
Optix Quantify measures actual savings, providing reliable results to utilities, grid operators, customers, and regulators. Building programs on a foundation of actual savings, rather than engineering estimates, provides DSM programs a consistent measurement platform. Actual savings measurements strengthen the case for increased market investment in energy efficiency programs from both utilities and third-party sources.
