Like Heather's question above, what if the equipment to be installed is less than 5 hp AND doesn't fall under the HVAC equipment categories listed in section 2.9 of the CPG, such as Variable Refrigerant Flow systems? The closest thing might be DX split systems, but this is not an apples-to-apples comparison since this equipment efficiency is regulated by ARI 340/360, yet VRF has no ARI standard, but is generally regarded to be more energy efficient. Can section 2.9 be deemed as not applicable in this case?

Also, what if the new HVAC systems are hydronic fan coils, less than 5 hp, served by an existing chiller and boiler outside the project scope? Can this credit still be achieved by just complying with section 1.4 of the CPG?
