Design values far entering wet bulb and dry bulb temperature shall be(o�the indoor dry bul6 and relative humidity used for the load calculalion and shall be adjusted for return side gains if the return duct(s)is installed in an unconditioned space. Excep#ions: 1 Attached single-and multi-family residential equipment sizing may be selected so that its cooling capacity is less than the calculated total sensible loed but not less than 80 percent of that load. 2. When signed and sealed by a Florida-registered engineer,fn attached single-and multi-famiiy units,the capacity of equipm�nl_m�be sized in accordance with good design practice. � R403,6.1.2 Heating equipment capacity ' R403.6.1.2.1 Heat pumps. Heat pumps sizing shall be based on the cooling requirements as calculated according to Section RA63.&.'1.1 and the heat pump tota(cooling capaeity shatl not be more than 1.15 times greater than the design cooling Ioad. . R403.6.9.2.2 Electric resistance furnaces. Electric resistance furnaces shall be sized within 4 kW of the design requiremenfs calculafed according to the procedure selected'm Section ft443.B.1. ' R403.6.1.2.3 Fossil fuel heating equipment. The capacity of fossil fuel heating equipment with natural draft atmospheric burners sha(i nof be less than fhe design laad calculated in accordance wiEh SecUon R403.6.1. � R403.6.1.3 Extra capacity required for special occasions. Residences requiring excess cooling or heating equipment capacity on an infermiftenf basis,such as anBcipafed additianal loads caused by major eniertainment events,shall have equipmsnt sized or controtled ta prevent continuous space cooling or fieating within that space by one ar more of the fo!(owing optians: 1. A separate cooling or heating system is utilized to provide coaling or heating to the major entertainment areas. 2. A variabie capacify system sized for optimum performance during base toad periods is utiiized. p t2443.7 Systems serving multiple dwelling units(Mandatorya.

The energy requirements for ressdentia!paofs and inground spas shalt be as specified in Sections R403.9.1 througfi R403.9.3 and in accorda�ce with ANSIIAPSP-i 5.The energy requirements for portable spas shall be in accordance with ANSI/APSP-14. p R4a3.9.1 Pool and spa heafers. AlI pool heaters shaf{be equipped with a readily accessibie on-aff switch that is mounfed outside the heater to allow shutting off the heater without adjusting the thermostat setting. i2403.9.4.1 Gas and oil-fired paot and spa heaters. Ati gas-and aii-fred poal and space heaters shall have a minimum thermal efficiency of 82 percent far heaters manufactured on or after April 16,2013 when tested in accordance wifh ANSi Z 21.56. Pool heaters fired by natural gas or LP gas shall not have continuously burning pilot lights. , R4d3.9.�1.2 Heat pump pool heafers. Heat pump poat heafers shall have a minimum COP of 4.0 when tested in accordance with AHRI 1160,Table 2,Standard Rating Conditions-Low Air Temperature.A test report from an independeni laboratory is � required to verify procedure compliance.Geothermaf swimming pool heat pumps are not required to meet this standard. O R403.9.2 Time switches. Time switches or other control method that can automaticaily turn off and on heaters and pumps according to a preset schedule shall be installed on all heaters and pumps.Heaters,pumps and motors that have built in timers shall be deemed in campiiance with this equlpment. Exceptions: • 1 Where pubiic health standards require 24-hour pump operations. 2. Where pumps are required to operate solar-and waste-heat-recavery pool heafing sys#ems. 3. Where pumps are powered exclusively from on-site renewable generation. O R443.9.3 Covers. Heated swimming paols and inground permanentiy instalied spas shali be equipped wifh a vapoe retardant caver on ar at the water surface or a liquid cover or other means proven to reduce heat loss. Exception: Outdoor pools deriving over 70 percent of the energy for heating from site-recovered energy,such as a heat pump or ' soiar ene�gy source computed over an operating season. ❑ RR404.1 Lighting equipmenE(Mandatory). A minimum of 75 percent af the lamps in permanently installed lighting fixtures shall be high-efficacy lamps or a mfnimum of 75 percent of permanenfiy instailed isghiing fixtures sha0 contain anly high e�cacy Iamps. Exception: Low-vottage fighting shalf not be required to utilize high-efficacy lamps. � R404.9.9�tghting equipmeat(Mandatory).
