The building officia(shal�require that an energy performance levei(EPL) dtsplay card be completed and certified by the builder to be accurate and correct before final approval of the building for occupancy. Florida law [S�ection 553.9085,Fiorida Statues]requires the EPL display card'to be included as an addendum ta each sales cantract far bath presolc3 and npnpresald residential buildings.The EPL display card contains information indicating the energy performance level and efficiencies of camponents installed in a dwelling unit.The building official shall verify that the EPL display card completed and signed by the builder accurately reflects the plans and specifications submitted to cfemonstrate compliance for the building.A copy of fhe EPt�disp}ay card can be faund in Appendix G. � RaIO2.4 Air leakage(Mandatory). The building thermal envelope shall be constructed to limit air leakage in accardance with the requirements of Sections R402.1 through R402.4 4. Q R402.4.1 Building thermal envelope. The building thermal envelope shall comply with Sections R402.4.1.1 and R402.4.1.2,The sealing methods between dissimilar materials shall allow for differential expansion and cantraction. � R402.A.1.1 tnstatiatian. The camponents af the building thermai enveiope as listed in Table R402.4.1.1 sha(1 be instailed in � accordance with the manufacturer's instructions and.the criteria listed in Table 402.4.1.1,as applicable ta the method of construction. Where required by the code afficial,an appeoved third party shaH inspect all components and verify comptiance. • R402.4.1.2 Testing. The building or dwelling unit shall be tested and verified 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 hour in Glimate Zones 3 through 8.Testing shall be condncted with a b(ower door at a pressure afi 0.2 inches w.g.{5d Pasca(s).Where required by the code official,testing shall be conducted by an approved third party.A written report of the results of the test shall be signed by the party conducting the test and provided to the cade afficial.Tesiing shal!be pertormed at any lime after creation a€all penetrations of the buitding therrnal envelape. During testing: 1.Exterior windows and doors,fireplace and stove doors shall be closed,but not sealed,beyond the intended weatherstripping or other infiltrafion cantrol measures; 2, Dampers including exhaust,intake,makeup air,backdraft and flue dampers shall be closed,but not sealed beyond intended infiltration control measures; 3.Interior doars,if i�stalled at the time af fhe test,shatl be open; , 4.Exterior doors for continuous ventilatian systems and heat recavery ventilators shall be closed and sealed; 5.Heating and cooling systems,if installed at the time of the test,shall be turned off;and 6.Supply and refum registers,if i�stalled at the time of the tesf,shal[be fully apen. O R402.4.2 Fireplaces. New wood-buming fireplaces shall have tight-fitting flue dampers and outdoor combustion air. � , O R402.4.3 Fer�estratioa air leakage.Windows,skyligfits and siiding giass doors shaiE have an air infltration rate of no more than d.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 tested according to NFRC 400 or AAMA/WDMA(GSA i01!l.S.2/A440 by an accrediied,independeni labaratary and listed and labeled by the manufacturer. Exception: Site-buiit windows,skyiights and doors. � Ft4Q2.4.4 Recessed lighting. Recessed luminaires installed in the building thermaf enveiope sha[I be seafed Eo limit air leakage , between conditioned and unconditianed spaces.All recessed luminaires shall be 1C-Yated and labele`d as having an air leakage rate not more than 2.0 cfm(0.944 Us)when tested in accordance with ASTM E 283 at a 1.57 psf(75 Pa)pressure differential.All recessed luminaires sha!!be sealed with a gasket or caulk between the housing and the interiar wall or ceiling cavering. ❑ R 03.1.1 Thermostat provision(Mandatary). At least one thermostat shall be provided for each separate heating and caoling system. ', � R4�3.1.3 Heat pump supplementary heat(1Utartdatory}. Heat pumps having supplementary electric-resistance heat sha11 have controEs th�t,except during defirost,prevent supplemental heat operation when the heat pump compressor can meet the heating load. � Fi4Q3.2.2 Seating(Mandatory}AH ducis,air handlers,and filter baxes and building cavities that form the primary air cantaittment passageways far air distribution systems shai(be considered ducts and plenum chambers,shaii be canstructed and sealed in accordance wi#�Section C403.2.7.2 of the Cammercial Provisions of this code and shall be shown to meet duct tightness criteria by post-construction or ugh-in testing 6elaw. Du t tightness shall be verified by testing to Section 803 of the RESNET Standards by either an energy rater certified in accordance with Section ' 55i.99,Florida Statutes,or as authorized by Florida Statutes,to be"substantially leak free"by either of the following: i 1.` Post-construction test:Total leakage sha(I be less than or equa(to 4 cfm(113 Vmin}per 100 square feet(9.29 m2}of conditioned flaor area : � when tested at a pressure differential of 0.1 inches w.g.(25 Pa)across the entire system,including the manufacturer's air handler enclosure.All ' register boots shal!be taped or otherwise sealed duting the test. 2. I Rough-in test:Total leakage shall be less than or equal to 4 cfm(113 Umin)per 100 square feet(9.29 m2)of conditianed floor area when tested �; , at a pressure differential of 4.1 inches w.g.(25Pa}across the system,.including the rnanufactttrer's air handler enc(osure.All registers sha{!be taped or otherwise sealed during the test.lfi#he air handler is not instalEed at the time of the test,total ieakage shall be iess than ar equai to 3 cfm �, (85 Umin)per 100 square feet(9.29 m2)of conditianed floor area. i F�ceptions: 1 The total leakage test is not required for ducts and air handlers Ipcated entirely within the building envelope. 2. Duct tesfing is not mandatory for huildings camplying by Section R405 of this code. 1 1141201 6 4:11 PM EnergyGauge�USA-FEaRes2014 -Secfion R405.4.1 Com Page 1 of 3
