FORM R405-2014 - IIAA�NDATORY REQUIREMENTS - �Continued) ' fl R403.6.1.1 Coo�ing equipment capacity.(continued) The published value for AHRI total capacity is a nominal,rating-test value and shall not be used for equipment sizing.Manufacture's expanded pertormance data sha!!be used to seleci cooling-only equipment.This ' selecfion shall be used ta select coaling-only equipment.Tt�is selecfion shall be based on the outdoor design dry hulb temperature far the load calculatian(or entering water temperature for water-source equipment),the blower cfm provided by the expanded performance data, the design value for entering wet bulb temperature and the design value for enfering dry bulb temperature. _ design vaiues for entering wet buib and dry bu{b temperature shall be for tfie indoor dry buib and reiative humidity used for the load calculation and shall be adjusted for retum side gains if 4he retum duct(s)is installed in an unconditioned space. Exceptions: 1. Attached single-and multi-family residential equipment sizing may be selected so that its cooling capacity is less than the calculated total sensibie load but nat less thart 80 percent of that load. 2. When signed and sealed by a Flarida-registered engineer,in attached single-and multi-family units,the capacity of - equipment may be sized in accordance wiin good cfesign practice. � R403.6.1.2 Heating equipment capacity ' R403.6.1.2.'t Heat•pumps. Heat pumps sizing shall be based an the coaling requirements as caiculated accarding fo Sectian R403.6,1.1 and the heat pump total cooling capacity shall not be more than 1.15 times greater than the design caoling load. . R403.6.'t.2.2 Electric resistance furnaces, Electric resistance fumaces shall be sized within 4 kW af the desiga requirements caicuiated according to the procedure selected in Section R403.6.i. ' R4U3.6.1.2.3 Fassil fuet heating equipment. The capacity af fossi!fue!heaiing equiprnent witn naturai draft aimospharic bumers. shall not be less than the design laad calcuiated in accordance with Section Fl403.6.1. � R403.6.1.3 E�cCra capacity reqaired far speclai occas[ons. Residences requiring excess cooling or heating equipment capacity an an, intermittent basis,svch as anticipated additiona(loads caused by major entertainment events,shail have equipment sized or cantrotled to prevent continuous space cooling or heating within that space by one or more of the following options: ; i. A separate cooling or hea#ing system is utilized ta provide coo[ing or heating to the major enterta3nment areas. 2. A variable capacity system sized for optimum performance during base load periods is utilized. p Fi 03.7 Systems servEng cnultiple dwe111ng units(lUlandatory). Systems serving rnultiple dweliing units shall carnp3y with Sections C 03 and C404 of the Commercial Provisions in lieu of 5ection R403. , p R Q3.8 Snow melt system controEs{Mandatflry}. Snow and ice-melting systems,supptied through energy service to the building,shall in lude automatic controls capable of shutting off the system when the pavement temperature is above 55°F,and no precipitation is falling an an automatic or manual control that will allow shutoff when the outdoor temperature is above 40�F. 0 R 03.9 Swimming poots,inground spas and portabie spas(Mandatory}. 1'he energy requirements for residential pools and in�round spas shall be as specified in Sections R403.9.1 through Fi403.9.3 and in accordance with ANSI/APSP-15.The energy II re u�reme�fs for partabEe spas shai!be in accardance 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 the heater to allow shutting oif ihe heater without adjusting the thermostat setting. , R403.9.7.1 Gas and oil-fired paol and spa heaters. All gas-and oil-fired pool and space heaters shall have a rninimum � thermal efficiency of 82 percent for healers manutactured on ar after April 16,2013 when tested in accordance with ANS!Z 21.56. Pao1 heaters fired by natura(gas ar C.P gas shal(not have continuously buming pilat lights. ' � R403.9.1.2 Heat pump pool heaters. Heat pump pool heaters shall have a minimum COP of 4.0 when tested in accordance � with AHFtI 1160,Tabie 2,Standard ftating Canditions-Low Air Temperature.A test report frorn an independent laboratory is required to verify procedure comp(iance.Geothermal swimming poo(heat pumps are not required to meet this standard. �O R403.9.2 Time switches. Time switches or ather contro!method that can automaticalty tum off and on heaters and pumps aocording to a , preset schedule shall be instalEed on all heaters and pumps.Heaters,pumps and mators that have bvilt in timers sha(I be deemed in compliance with this equipment. F.�cceptions: • 1. Where public health standards require 24-hour pump operations. 2. Where pumps are required to operate solar-and waste-heat-recovery pool heating systems. i i 3. Where pumps ara powered exc3usively irom on-site renewabie generatia�. , �O R403.9.3 Govers. Heated swimming paols and inground permane�tly installed spas shall be equipped with a vapor-retardant cover on or ; i at the water surface ar a liquid cover or other means proven ta reduce heat Eass. , Exception: Outdo�r pools 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. � ❑ RR 04.1 i.ighting equipmen#(Mandatory). A minimum of 75 percent of the famps in permanently installed Iighting fi�ures shail be high�efficacy lamps or a minimum af 75 percent of permanently installed lighting fiickures shall contain only high efficacy lamps.
