The NZ roadmap sets out the purpose for developing different scenarios and the methodology to evaluate the impact of different combinations of decarbonisation options on energy consumption and carbon emissions. Included within the NZ roadmap is the Measurement and Verification (M&V) process of verifying energy savings in a transparent and fair manner. Various protocols for good practice in Measurement and Verification exist globally but the most widely used is the International Performance Measurement and Verification Protocol (IPMVP), which defines common terminology and the key steps in implementing a robust M&V process. A key part of the M&V process is the development of an 'M&V Plan', which provides a comprehensive outline to guide the M&V process in line with IPMVP requirements.
