If you are following Option 1, then the efficiency requirements of the new equipment are provided in the Core Performance Guide section 2.9. If your new equipment has a better efficiency than the values listed in the table, then it meets this part of the requirements. The design must also meet the requirements of section 1.4: Mechanical System Design and 3.10: Variable Speed Control (if applicable).
If you are following Option 2, then the baseline requirements are the minimum requirements of ASHRAE 90.1- 2007
