I am not clear from CPG whether VAV is required for Option1 (Equipment Efficiency - 5 points). I have Constant Volume RTUs serving the tenant space. All of them have supply fan less than 5 HP. Can this qualify under option1?
Also latest CPG states that "Packaged unitary equipment shall meet the minimum efficiency requirements in table 2.9.1 and 2.9.2 and be Energy Star labeled." I used to think that either the packaged system has to qualify the above tables or Energy Star but not both. Any views will be appreciated.

Free and fast, pick one. :-)
As long as your fan motors are less than 5 HP they do not need to comply so you should be fine under option 1.
The previous version of CPG also says "and". For an international project I would think that if you can demonstrate that it meets the efficiency requirement it would not necessarily have to also be ES labeled.
