Table 406.2 • Energy Credits (2015 Code) OPTION DESCRIPTION CREDIT(S) Estimated Cost 2c AIR LEAKAGE CONTROL AND EFFICIENT VENTILATION 2c: 1.5 Compliance based on Section R402.4.1.2: Reduce the tested air leakage to 1.5 air changes per hour maximum and All whole house ventilation requirements as determined by Section M1507.3 of the International Residential Code shall be met with a heat recovery ventilation system with minimum sensible heat recovery efficiency of 0.85. To qualify to claim this credit,the building permit drawings shall specify the option being selected and shall specify the maximum tested building air leakage and shall show the heat recovery ventilation system. 3a" HIGH EFFICIENCY HVAC EQUIPMENT 3a: 1.0 Gas,propane or oil-fired furnace with minimum AFUE of 94%,or Gas,propane or oiled-fired boiler with minimum AFUE of 92% To qualify to claim this credit,the building permit drawings shall specify the option being selected and shall specify the heating equipment type and the minimum equipment efficiency. 3b' HIGH EFFICIENCY HVAC EQUIPMENT 3b: - 1.0 Air-source heat pump with minimum HSPF of 9.0 To qualify to claim this credit,the building permit drawings shall specify the option being selected and shall specify the heating equipment type and the minimum equipment efficiency. 3e" HIGH EFFICIENCY HVAC EQUIPMENT 3c: 1.5 Closed-loop ground source heat pump;with a minimum COP of 3.3 or Open loop water source heat pump with a maximum pumping hydraulic head of 150 feet and minimum COP of 3.6 To qualify to claim this credit,the building permit drawings shall specify the option being selected and shall specify the heating equipment type and the minimum equipment efficiency. 3d1' HIGH EFFICIENCY HVAC EQUIPMENT 3d: 1.0 Ductless Split System Heat Pumps,Zonal Control:In homes where the primary space heating system is zonal electric heating,a ductless heat pump system shall be installed and provide heating to the largest zone of the housing unit. To qualify to claim this credit;the building permit drawings shall specify the option being selected and shall specify the heating equipment type and the minimum equipment efficiency. 4 HIGH EFFICIENCY HVAC DISTRIBUTION SYSTEM: 1.0 All heating and cooling system components installed inside the conditioned space. This includes all equipment and distribution system components such as forced air ducts,hydronic piping,hydronic floor heating loop,convectors and radiators.All combustion equipment shall be direct vent or sealed combustion. For forced air ducts:A maximum of 10 linear feet of return ducts and 5 linear feet of supply ducts may be located outside the conditioned space.All metallic ducts located outside the conditioned space must have both transverse and longitudinal joints sealed with mastic.If flex ducts are used,they cannot contain splices.Flex duct connections must be made with nylon straps and installed using a plastic strapping tensioning tool. Ducts located outside the conditioned space must be insulated to a minimum of R-8_ Locating system components in conditioned craw]spaces is not permitted under this option. Electric resistance heat and ductless heat pumps are not permitted under this option. Direct combustion heating equipment with AFUE less than 80%is not permitted under this option. To qualify to claim this credit,the building permit drawings shall specify the option being selected and shall specify the heating equipment type and shall show the location of the heating and cooling equipment and all the ductwork.
