-------
technological and/or market changes affect its usefulness to consumers, industry, or the environment.
In keeping with current policy, revisions to the specification are arrived at through industry
discussions. In the event of a specification revision, please note that the ENERGY STAR qualification
is not automatically granted for the life of a product model.

Energy Efficiency Criteria for Equipment <65.000 Btu/h: In 2010, EPA intends to evaluate Tier 1
performance levels in this Version 2.1 specification for single package and split system central air
conditioner and air-source heat pump equipment rated below 65,000 Btu/h to determine if new levels
are warranted for Tier 2. EPA plans to use the performance data provided in the AHRI Certified
Directory to establish Tier 2 requirements with the goal of representing approximately the top 25% of
available models. Tier 2 is scheduled to go into effect on July 1, 2011.

Energy Efficiency Criteria for Equipment > 65,000 Btu/h: EPA intends to revisit the performance levels
presented in this Version 2.1 specification for equipment rated at and above 65,000 Btu/h once more
IEER data become available. This IEER data will help EPA to characterize the market with regard to
model availability, evaluate cost-effectiveness, and determine whether the levels in Tables 1 and 2 of
this Version 2.1 specification represent the top energy efficiency performers. EPA expects to begin the
Tier 2 review process immediately following the Tier 1 effective date (i.e., May 1, 2010). Tier 2 is
scheduled to become effective on July 1, 2011.

Similar to the Version 2.1 development process, any revisions to the program requirements will be
shared with industry stakeholders for review and comment.
