These rating methods also underlie policies that promote adoption of high performance products, such as performance labels and public benefit incentives. A good testing procedure that closely approximates field performance increases confidence that programs and policies will actually save energy.

Therefore, developing and refining these methodologies is a continual process and a critical one to ensure sound policy and to minimize market barriers.
