7.20.2 Measurement and Verification key concepts

Two key concepts form the basis for IPMVP. The first is that the post project consumption is not compared with a fixed baseline but with an estimate of what the energy consumption would have been under the conditions after implementation of the project. This requires an understanding of the factors which are driving the energy use (e.g. weather, building use, building occupancy) and developing a mathematical model to relate energy to the relevant factors. The baseline energy is then adjusted according to the level of these factors in the post-installation (reporting) period. This is illustrated in Figure 8 where an increase in production post baseline has led to an upward adjustment of the baseline energy being applied, which is then measured against the actual reported energy to determine savings or avoided energy consumption.

Secondly, IPMVP also requires an M&V Plan to be produced prior to the energy saving project being implemented. This must be agreed among the Authority, Project Co and FM service provider so that evaluation procedures and key data requirements are set before the savings evaluation after project implementation (see further details below).
