The reference procedures and method described in this manual establish the basis of comparison for all compliance software. The approval process ensures that a minimum level of energy efficiency is achieved regardless of the compliance software used. This level is accomplished by:

• Specifying a series of reference method comparison tests that candidate compliance software passed.
• Specifying input that may vary for credit, and input that is fixed or restricted.
• Defining standard report output requirements.
• Certifying the software vendor requirements in this manual.
