We received a review comment back, on Energy Modeling report use to document EA cr1.3, that stated the following: "The Proposed design air cooled chiller COP for office is indicated 2.5 does not comply with the requirements of ASHRAE 90.1-2007, Section which requires the minimum efficiency requirement of air cooled chiller per Table 6.8.1.C. This will preclude the project from using Alternate Baseline method"
The reviewer goes on to recommend using the Baseline method of modeling instead. My question is if the design chiller COP used in the model was too low to meet the requirements, couldn't we just simply rerun the model using the min. efficiency COP from Table 6.8.1.C. ...which should generated even better savings? Am I missing something here?
