Q: What is the relationship between IPMVP and cost-effectiveness testing?

A: I assume that cost effectiveness tests (CET) is referring to standard demand-side energy management program tests such as Participant Cost Test, Total Resource Cost Test, etc. (see http://www.epa.gov/sites/production/files/2015-08/documents/cost-effectiveness.pdf). CET's require a number of inputs, including energy or "resource" savings and utility bill savings. Energy and utility bill savings are common outcomes (or outputs) of M&V activity, and these outcomes can be used as inputs to various CETs. CET's can be calculated based on pre-project estimates of expected energy and utility bill savings, in which case the CET's could not use M&V results.
