The building official shall require that an energy performance level(EPL) disP ay card be completed and certified by the builder to be accurate and correct before finaf approva!of the bui(ding for occupancy.Florida law [Se�tion 553.9085,Fiorida Stafues�requires the EPL display card to be included as an addendum to each sales contract for both presold and non resold residential buildings.The EPL display oard cdntains information indicating the energy pertormance level ahd efficiencies af components installed in a dwe!ling unit.The building officia!shall verify that the EPl..display card completed and signed by the builder accuraiely reflecis the pians andi{specifications submitted to demonstrate compliance far the building.A copy flf the EPL disp{ay card can be found in Appendix G. � R402.4 Air leakage(Mandatory). The building thermal envelope shall be constructed to limit air leakage in accordance with the requirements of Sec}ions R402.1 through ft4d2.4.4. IIQ R402.4.1 Building thermal envelope. The building thermal envelope shall comply with Sections R402.4.1.1 and R402.8.1.2.The sealing methods between dissimilar materials sha!!ailow far differentia!expansion and coniraction. • R402.4.1.7 Installation. The components of the building thermal envelope as listed in Table R402.4 1.1 shall be installed in accordance with the manufacturer's lnstructions and the criteria listed in Table 402,4.1.1,as applicable to the method of consiruclion. Whare required by the code afficial,an appraved third party shall inspec#aI1 components and verify compliance. ■ R402.4.1.2 Testing. The building or dwelling unit shall be tested and veri�ed as having an air leakage rate of not exceeding 5 air changes per hour in Glimate Zones 1 and 2,and 3 air changes per haur in Glimate Zanes 3 through 8.Testing shall be conducted with a biawer door at a pressure of 0.2 inches w.g.(50 Pascals).Where required by the code official,testing shall be conducted by an approved third party.A written report of the results of the test shali be signed by the party conducting the test and provided to the code afficial.Testing shall be performed at any time after creation af aIl penefrations of#he bui(ding thermal envelope. During testing: 1 E�cierior windows and doors,fireplace and stave doors shali be closed,bui not sealed,beyond the intended weatherstripping or other infiltration control measures; - 2. Dampers including exhaust,intake,makeup air,backdraft and flue dampers shall be closed,but nat sealed beyond intended infiliraiion contro!measures; 3.In#erior daors,if installed at the time of the test,sha((be open; 4 E�erior doors for continuous ventflation systems and heat recovery ventilators shall be clased and sealed; 5.Neating and cooling systems,if installed at ihe time of the test,sha11 be turned off;and 6.Supply and return registers,if insta(ied at the time of the test,shall be fully open. �O R4Q2.4.2 Fireplaces. New wood-burning firepiacss shall have tight-fitting ffue dampers and outdoor combustion air. (� R402.4.3 Fenestration air leakage.Windows,skylights and sliding glass doors shall have an air infiltration rate of no more than 0.3 cfm per square foot(1.5 Us/m2),and swinging doors no more than 0.5 cfm.per square foot{2.6 Us/m2),when iested according to NFRG 400 or AAMAIWI7MAiCSA 10111.S.21A440 by an accredited,independant lat�oratary and Eisted and labeled by fhe manufacturer Exception: Site-built windows,skylights and daors. (� R4Q2.4.A Recassed lighting. Recessed luminaires installed in the bui(ding fherrnal envelape shall be sealed to(imit air leakage between conditioned and unconditioned spaces.All recessed luminaires shall be IG-rated and labeled as having an air leakage rate not more ihan 2.0 cfm(Q.944 Us)when tesied in accordance with ASTM E 283 at a 1.57 psf{�5 Pa)pressure differential.All recessed luminaires shall be sealed with a gasket or caulk between the housing and the interior wal(or ceiiing covering. � R403.1.1 Thermostat provision(Mandatory). At least one thermostat shall be provided for each separate heating and cooling system. I� j � R4C}3.1.3 Heat pump supplementary heat(Mandatary}. Heat pumps having supplementary electric-resistance heat shal(have controis i that��except during defrost,prevent supplemental heat operation when the heat pump compressor can meet the heating load. � R403.2.2 Sealing{Mandatory)AIl ducts,air handlers,and filtar boxes and building cavities Ehat forrrt the primary air cantairsment passageways for.air distributian systems shall be considered ducts and plenurn chambers,shall be constructed and sealed in accordance withl Section C403.2.7.2 of the Commercial Provisions of this code and shall be shown to meet duct tightness criteria by post-canstruction or rl ugh-in testing below. Duc tightness shall be verified by testing to Section 803 of the RESNET Standards by either an energy rater.certified in accardance with Section 553�99,Fiorida Statutes,or as authorized by Florida Statutes,To be"substantia(ly leak free"by eiiher af ihe folfowing: 1. Post-construction test:Total leakage shall be less than or equal to 4 cfm(113 Umin)per 100 square feet(9.29 m2)of conditioned floor area when tested a2 a pressure differ�ntial of 0.1 inches w.g.(25 Pa)across the entice system,including the manufacturer's air hancller enciosure.Ali register boats shall be taped or otherwise sealed during the test. 2. Rough-in test:Total leakage shall be leas than or equal to 4 cfm(113 l.lmin)per 100 square feet(9.29 m2)of conditioned floor area when fesied at a pressure differential of 0.1 inches w.g.{25Pa}across the system,incEuding the manufacturer's air handler enclosure.All registers shall be taped ar otherwise sealed during the test.If the air handler is not installed at the time of the test,total leakage shall be less than or equal to 3 cfm (85 Umin)per 100 square feet(9.29 m2)of conditioned floor area. � xcepfions: j1 The total leakage test is nat required for ducts and air handlers located entirely within the building envelope. � Duct testing is not mandatory for buiidings complying by Section Fi405 of this code. � 10/18/2016 4:14 PM EnergyGaugeO USA-FlaRes20i 4 -Section R405.4 1 Com Page 1 of 3
