I think the simple answer is that EnergyPlus (for which DB is an interface) uses COP for cooling coils. This is a long-standing situation! You need to convert EER to COP. For packaged systems, this requires adjusting EER to account for the fan power - not a simple numerical conversion. You can find conversion procedures (I think) by searching this forum or contacting me privately. I'd be happy to help. (jim at fsmgmt.co)
