§ 5E-2-1 H AWAI‘I C OUNTY C ODE Fuel type: same as proposed design.As proposed Efficiencies: As proposed Electric: Air-source heat pump with prevailing federal minimum standards. Nonelectric furnaces: natural gas furnace As proposed d, e Heating systems with prevailing federal minimum standards. Nonelectric boilers: natural gas boiler with As proposed prevailing federal minimum standards. Capacity: sized in accordance with Section As proposed R403.7. Fuel type: Electric Efficiency: in accordance with prevailing As proposed d, f Cooling systems federal minimum standards. Capacity: sized in accordance with Section As proposed R403.7. Fuel type: same as proposed designAs proposed Efficiency: in accordance with prevailing As proposed Service water federal minimum standards. d, e, f, g heating Use: Same as proposed design gal/day = 30 + (10 × N) br Duct insulation: From Section R403.2.1 A thermal distribution system efficiency (DSE) of 0.88 shall be applied to both the As tested or as specified heating and cooling system efficiencies for Thermal distribution in Table R405.5.2(2) if not all systems other than tested duct systems tested. Duct insulation systems. For tested duct systems, the shall be as proposed. leakage rate shall be 4 cfm (113.3 L/min) 22 (9.29 m) of conditioned floor per 100 ft area at a pressure of differential of 0.1 inches w.g. (25 Pa). Type: Manual, cooling temperature Same as standard Thermostat setpoint = 75°F; reference Heating temperature setpoint = 72°F 2 For SI: 1 square foot = 0.93 m, 1 British thermal unit = 1055 J, 1 pound per square 2 , 1 gallon (US) = 3.785 L, °C = (°F-32)/1.8, 1 degree = 0.79 rad. foot = 4.88 kg/m a. Where required by the code official, testing shall be conducted by an approved party. Hourly calculations as specified in the ASHRAE Handbook of Fundamentals, or the equivalent shall be used to determine the energy loads resulting from infiltration. SUPP. 9 (1-2021) 5E-24
