Evaluation, measurement, and verification (EM&V) is the collection of methods and processes used to assess the performance of energy efficiency activities so planned results can be achieved with greater certainty and future activities can be more effective.
The main objectives of an EM&V process are to assess the performance of an energy efficiency program or project, to measure the energy or demand savings, and to determine if the program is generating the expected level of savings. EM&V data can inform recommendations for improvements in program performance. Having a clear understanding and description of how the program is expected to deliver results is critical to an effective EM&V process.
State regulators, public and private energy efficiency portfolio administrators, program implementers and evaluators can use the following resources to help with:
- Guidance on planning evaluation efforts
- Approaches for determining and documenting program impacts
- Improving the efficacy of energy efficiency portfolios
- Comparing demand- and supply-side resources.
