FORM R405-2014 �t1�1NDATORY �2�QUlREf[�iEMTS - (Gontinued) 0 R403.6.1.1 Coaling equipment capacPty.(continued) The published valua for AHRi tota(capacify is a naminal,rating-test value and shall npt be used for equipment sizing.Manufacture's expanded performance data shall be used to select cooling-only equipment.This selecfiort shall be.used to select cooiing-only equipment.7his selection sha!!be based on the outdoor design dry bulb temperature for the load caiculation(or entering water temperature for water-source equipmeni},the b(ower cfm pcovided by fhe expanded performance data, the design value for entering wet bulb temperature and the design value for entering dry bulb temperature. Design va(ues far entering wet buSb and dry bulb temperature shalS be for the indoor dry bulb and relative humidity used for the load calculation and shall be adjusted for return side gains if the return duct(s)is installed in an unconditioned space. Excep6ans: 1 Attached single-and multi-family residential equipment sizing may be selected so that its cooling capacity is less than the ' calculated kotai sensibie loed but nat less than 80 percent of that load. i 2. When signed and sealed by a Florida-registered engineer,in attached singie-.and muiti-fami(y units,the capaci#y of i — equipmQnk�ay be sized in accordance with good design practice. � R403.6.1.2 Heating equipment capacity ` E2A03.6.9.2.1 Neat pumps. Heat pumps sizing shaii be based on the cooling requirements as calculated accarding to Section R403.6.1.1 and the heaf pump total cooling capacity shall not be more than 1.'I5#imes greater fhan the design cooling Eoad. . R403.6.9.2.2 Electric resistance furnaces. Electric resistance furnaces shall be sized within 4 kW of the design � requirements calculated accarding ta the pracedure selecfed in Section R4�3.6.'1. ' R403.6.1.2.3 Fossil fuel heating equipment. The capacity of fossil fuel heating equipment with natural draft atmospheric burners � shall rrot be less than the design load caiculated in accardance with 8ection R403.6.1. � R403.6.1.3 Extra capacity required for special occasions. Residences requiring excess cooling or heating equipment capacity on an intermittent basls,such as anticipated additiona!loads caused by majar entertainment events,shali have equipment sized or contro!!ed ta prevent continuous space coo�ing or heating within that space by one or more of the foliowing options: 1. A separate cooling or heating system is utilized to provide cooling or heating to the maJar entertainment areas. 2. A variabie eapacify system sized for optimum performance during base laad periads is utitized. p f2403.7 Systems serving multip{e dwel{ing units{Mandatory). Systems servi�g multiple dwelling units shall comply with Sections C403 and C404 of the Commercial Pravis3ons in lieu of Section R403. p R403.&Snow melt systam controls(Mandatory). Snow and ice-melting systems,supplied through energy service to the building,shall 3nclude aufomatic confrois capable af shutting off the sysfem when fhe pavement temperature is abova 55'F,and no precipitatian is falling and an automatic or manual control that will allow shutoff when the outdoor temperature is above 40°F C3 R403.9 Swimming poois,Enground spas and portabte spas{Mandafary}. The energy sequirernents for residentiai poals and inground spas shafi be as specified in Sections R403.9.1 thraugh R403.9.3 and in accordance with ANSI/APSP-15.The energy requirements for poRable spas shall be in accordance with ANSI/APSP-14. p R403.8.1 Poo1 and spa heaters. A[I poo3 heaters shail be equipped with a readiIy accessibEe on-aff swifch that is mounfed outside the heater to allow shutting off the heater without adjusting the thermostat setting. R4d3.9.4.4 Gas and ai!-#ired poot and spa heaters. AlI gas-and oi1-fired pooi and space heaters shall have a mtnimum � thermal efficiency nf 82 percent for heaters manufactured on or after April 16,2013 when tested in accordance with ANS�Z 21.56. Pool heaters fired by natural gas or LP gas shall not have continuously buming pilot lights. o R403.9.1.2 Heat pump poat heaters. Neat pump pooi heaters shai!have a minimum GCiP of 4.0 when fesfed in accordance with AHRI 1160,Table 2,Standard Rating Conditions-Low Air Temperature.A test report from an independent laboratory is � required to verify procedure compliance.Geotherma!swimming poo!heat pumps are not required to meet this standard. O (2403.8.2 Time switches. Time switches or other control methad that can automatically turn off and on heaters and pumps according to a preset schedule sha!!be installed on all heaters and pumps.Heaters,pumps and motors that have built in timers shall be deemed in comp(iance with this equipmenf. Exceptians: - 1 Where public health sfandards require 24-hour pump operations. 2. Where pumps are required to operate solar-and westefieat-recovery paol heating&ystems, 3. Where pumps are powered exclusively from on-site renewable generation. O R403.9.3 Covers. Hea#ed swimming pools and inground permanent►y installed spas shall be equipped with a vapor-refardant cover on or at ihe water surface or a liquid cover or other means proven to reduce heat loss. Excepttan: Outdoor 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 seasan. ❑ RR404.1 Lighting equipment{Mandatory). A minimum of 75 percent of the lamps in permanently installed lighting fixtures shall be high-etficacy Iamps or a minimum of 75 percent af permanentiy instal(ed Sighting fixtures shaii cantain aniy hlgh e�cacy lamps. Exception: Low-voltage lighting shall not be required to utilize high-efficacy famps. O R4U4.1.1�ighting equipment{Mandatory). Fue!gas lighting systems shall not have continuously burning pilot lights � R405.2 Performance ONLY. AII ducfs not entirely inside the building thermal enveiope shalt be i�sulated to a minimum of R-6. , O R405.2.1 PerFormance ONLY.
