We are working on a project which falls under the category of System 6 - Packaged VAV with PFP Boxes for the Baseline Building. The cooling system associated with this is "Direct Expansion" and you are referred to Section 6.4 for Efficiency Ratings/Levels.

In Section 6.4, it is not clear which equipment type corresponds to Packaged VAV with Direct Expansion? It appears that it could be from Table 6.8.1A, Table 6.8.1B or Table 6.8.1D. We believe the most representative system would be Table 6.8.1A Air Conditioners, Air Cooled (Package System).

Clarification on the above would be appreciated - thank you in advance!
