The Federal Energy Management Program (FEMP) Measurement and Verification (M&V) guidelines provide a standardized method for quantifying energy savings in federal buildings. These guidelines are intended to ensure that energy savings calculations are accurate, consistent, and verifiable.
The International Performance Measurement and Verification Protocol (IPMVP) is a globally recognized standard for M&V in energy efficiency projects. It provides a flexible framework for determining energy savings and includes options for different levels of measurement accuracy and complexity.
National Energy Measurement and Verification Protocols (NEMVPs) are similar to the IPMVP but are specific to individual countries. They provide specific guidelines and requirements for M&V in that country, and may differ from the IPMVP in certain ways.
In summary, FEMP M&V guidelines, IPMVP, and NEMVPs are all protocols for measuring and verifying energy savings in buildings and facilities. They provide a standardized method for quantifying energy savings, and ensure that the savings are accurate, consistent, and verifiable.
