FORM R�05-2014 � 1VIA�IQATQEiY REQUIREMENTS - (Continued) 0 R403.B.1.1 Cooling equipment capacity.(continued) The published value for AHRI total capacity is a nominal,rating-test value and sha(f not be used for equipme�t sizing.Manufacture's expanded performance data shall be used to•seleet cooling-anly equipment.This selection sha(I be used to se(ect coaling-anly equipment.This seEecfion shal[be hased an fhe outdoor design dry bulb temperature for the load calculation(or entering water temperature for wa#er-source equipment),the blower cfm provided by the expanded performance data, the design value far entering wet bulb temperature and the design value for entering dry buib temperature. _ Design values for entering wet bulb and dry bulb temperature shall be for the indoor dry bulb and relative humidity used for the load calculation and shall be adjusted for retum side gains if the return duct(s)is installed in an unconditioned space. Exceptians: 1 Attached singie-and multi-family residential equipment sizing may be selecied so that its cooling capacity is less than the ca(cu3ated tota(sensible(aad bttt nat less than 8d percent af that load. 2, When signed and sealed by a Florida-registered engineer,in attached single-and multi-family units,the capacity of equipment may be sized in accordance wiin good design practice. � R403.6.1.2 Heating equipment capacity ' R4�3.6.1.2.1 Heat pumps. Heaf pumps sizing shai(be based on the cao3ing requirements as calculated according to Section R403.6.1.1 and the heat pump total cooling capacity shall not be more than 1.15 times greater than the design cooling load. . R903.6.'1.2.2 Electric resistance furnaces. Electric resistance furnaces shall be sized within 4 kW af the design requirements calculated according to the procedure selected in Section R403.6.1. ' R403.fi.1.2.3 Fossit fuel heating equipment. The capacity af fossi!fuei heating equipment with nafurai draft atrrtaspheric bumers shall not be(ess#han the design load calcuiated in accordance wi#h Section R403.6.1. Q R40S.6.'f.3 E�ctra capacity required for special occasions. Residences requiring excess cooling or heatirtg equipment capacity on an intermittent basis,such as anticipated additional loads caused by major entertainment events,shall have equipment sized or controlled to prevent continuous space cooling or heating within that space by one or more of the following options: 1. A separafe coating a�heating system is utilizsd to provide coaling or heating ta the major entertainment areas. 2. A variable capacity system sized for optimum performance during base load periods is utilized. O R403.7 Systems serving multlple dwelling anits(Nlandatoryj. Sys#ems senring multip(e dweliing units shai(comply with Sections C403 and C404 of the Cammercial Provisions in lieu of Section R403. Q R403.8 Snow melt system controEs{Mandatary). Snow and ice-melting systems,supp(ied through energy service to the building,sha!( include automatic controls capable of shutting off the system when the pavement temperature is above 55°F,and no precipitation is falling and an automatic ar manual control that will allow shutoff when the outdoor temperature is ebove 4Q°F. � R403.9 5wimming pools,inground spas and portable spas(Mandatory). 7he energy requirements for residential pools and inground spas shall be as specified in Sections R403.9.1 through R403.9.3 and in accordance with ANSI/APSP-15.The energy requiremenfs for partable spas shal[be in accordance with ANSIIAPSP-14. Q R403.9.1 Pool and spa heaters. All pool heaters shall be equipped with a readily accessible on-off switch that is mounted outside tha heater to ailow shutting off the heater without adjusting the therrnostat setting. � R403.9.1.1 Gas and oil-fired pool and spa heaters. All gas-and oil-�red pool and space heaters shali have a rninimum thermai efficiency of 82 percent for heaters manu#acYured on or after App)16,2019 when tested in accordance with ARISf Z 2i.56. Poal hea#ers ftred by natural gas ar LP gas shal(not have continuousiy buming pi{ot(ights. � R403.9.1.2 Heat pump pooi heaters. Heat pump pool heaters shall have a minimum COP of 4.0 when tested in accordance with AHRI i 16�,Table 2,Standard Rating Gonditions-�aw Air Temperature.A test repart fram en independent labaratory is required to verify procedure compliance.Geothermal swimming paol heat pumps are not required to meet this standard. O R403.9.2 Time switches. Time switches or oiher contro(methad that can auiomatically#um off and an heaters and gumps according ta a preset schedule sha(1 be instailed on all heaters and pumps.Heaters,pumps and motors that have buiit in timers shall be deemed in compliance with this equipment. Exceptions: • 1. Where public health standards require 24-hour pump operations. 2. Where pumps are required to operaie solar-and waste-heat-recovery poo!neating sysfems. 3. Where pumps are powerad exclusively from on-site reaewable generation. O R403.9.3 Covers. Heated swimming pools and inground permanently installed spas shall be equipped with a vapor-retardant cover on or at the water sur�ace or a liquid caver or ot}�er means praven to reduce heai loss. Exception: Outdoor poals deriving over 70 percent of the energy for heating from site-recovered energy,such as a heat pump or ' solar energy source computed over an operating season. ❑ RFi404.1 Lighting equipment(Mandatory). A minimum of 75 percent of the�amps in permanently insta�ied lighting fixtures shall be high-efficacy lamps or a minimum af 75 percent af permanently installed lighting fi7ctures shall contain only high efficacy lamps. Excegtion: Law-voltage lighfing shail nat be required to ufilize high-efficacy Iarrips. � R404.1.1 Lighting equipment(Mandatory). Fuel gas lighting systems shall not have cantinuausly burning pilot lights � R405.2 Performance ONLY. A!i d�cts not entirely inside ihe buiiding thermal envelope shaIl be.insulated to a minirnum of R-6, O R405.2.1 Pertormance ONLY. Ceiiings shall have minimum insulation af R-19.Where single assemby af the exposed deck and beam type or concrete deck roofs do not have sufficent space, R-10 is allowed. 1 i1412016 3:25 PNf EnergyGaugc�USA-FlaRes2614 -Secfiar�R4d5.4.1 Gom Page 3 af 3
