When projects have been implemented without an M&V Plan, but independent evaluation is still required.

The business constraints of financing a project whilst capital is available, pressure to deliver results today rather than tomorrow and lack of available historical data can mean that an IPMVP adherent process is not possible.

This does not mean that the M&V is without value, but may mean that that the uncertainty around any savings reported is higher. We use whatever data is available to provide the most accurate report possible.
