Equipment cooling efficiency shall be better than the WSEC required minimum efficiency by at least 64% in Climate Zone 4C and 59% in Climate Zone 5B per Table C403.3. System ID Exp 4 Equipment that provides hydronic chilled water for chilled beams and chilled ceiling systems that is served by a water economizer system per C403.3.4 in lieu of air economizer. System ID Exp 5 Water -source heat pumps with heat recovery. Heat pump efficiency shall be 15% better than WSEC required minimum efficiency. Provide at minimum 60% air economizer. Energy recovery to preheat OSA shall have at least 50% effectiveness. Additional system requirements apply. System ID Exp 6 Cooling equipment serving Group R occupancies. Per unit limit is less than 20,000 Btu/h cooling capacity for equipment installed outdoors or in a meth room adjacent to the outdoors. For cooling equipment installed in other locations the unit limit is less than 54,000 Btu/h. Efficiency shall be 15% better than WSEC required minimum efficiency. i System ID Equipment Location Cooling Capacity (Btu/h) Exp 7 Variable refrigerant flow (VRF) systems with energy recovery. Outdoor unit shall be a reverse -cycle heat pump with variable speed compressor(s) and condenser fan(s). Outdoor unit cooling capacity shall be not less than 65,000 Btu/h. Energy recovery to preheat outdoor air shall have at least 50% rated effectiveness. System shall be capable of providing simultaneous heating and cooling by tranferring recovered energy from zone(s) in cooling mode to other zone(s) that are in heating mode. Outdoor Unit System ID Cooling Capacity (Btu/h) Exp 8 Cooling equipment serving Controlled Plant Growth Environments. Equipment cooling efficiency shall be better than WSEC required minimum efficiency by at least 20%. Not eligible: unitary and applied heat pumps. System ID SEER, EER, & IEER Exp 9 Cooling equipment with energy recovery. Spaces served shall have year-round design cooling loads from lights and equipment greater than 5 watts per square foot. Energy recovery system shall utilize recovered energy for on -site space heating or preheating of service hot water. Provide calculations to the code official that demonstrate the amount of recovered energy used for on -site heating purposes is equivalent to the annual energy that would be saved by the cooling system with air economizer per C403.3.
