[] n40e.4 Air leakage<Mongatory>. The building thermal envelope shall be constructed to limit air leakage in accordance with the requirements of Sections n^uo/through nwux4.4 . ��' O R*oo.«.1ouim|n8mhemoa/wmve!vne The hundino thermal envelope shall comply mNo8em �.—F saa|inmmothodabaxwoenuias|nd|ormamhmxsxvoaoow for differential expansion and contraction. ^ m40c4.1'1 Installation.The components uf the building thermal envelope aa listed in Table n«me.41.1 shall be installed in accordance with the manufacturer's instructions and the criteria listed in Table 402.4.1.1,as applicable to the method of construction. Where required by the code official,an approved third party shall inspect all components and verify compliance. ^ n402.*.1.2Tosung. The building or dwelling unit shall ba tested and verified ua having un air leakage ratev/notmmoedinDuair changes per hour in Climate Zones 1 and 2,and 3 air changes per hour in Climate Zones 3 through u.Testing shall m,conducted with u blower door ata pressure ofo.2 inches w.g.(50 Pascals).Where required by the code official,testing shall be conducted by an approved third party.x written report vf the results of the test shall ue signed by the party conducting the test and provided m the code official.Testing shall be performed at any time after creation of all penetrations of the building thermal envelope. During testing: 1.Exterior windows and doors,fireplace and stove doors shall uo closed,but not sealed,beyond the intended weatherstripping mr other infiltration control measures; 2.Dampers including exhaust,intake,makeup air,backdraft and flue dampers shall be closed,but not sealed beyond intended infiltration control measures; o.Interior doors,if installed u'the time nfthe test,shall uaopen; 4.Exterior doors for continuous ventilation systems and heat recovery 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 return registers,if Installed at the time of the test.shall be fully open. O R402.4.2 Fireplaces.New wood-burning fireplaces shall have tight-fitting flue dampers and outdoor combustion air. O R402.4.3 Fenestration air leakageVVindows,skylights and sliding glass doors shall have an air infiltration rate of no more than O.acfm per square foot tuUuxnu>.and swinging doors no more than V.00mo per square foot(2.oupxnu).when tested according mmpRo*000, xxmmvNDw^/CSA l0l/L&2/A440 by an accredited,independent laboratory and listed and labeled by the manufacturer. Exception: Site-built windows,skylights and doors. u R4n2AA Recessed lighting. Recessed luminaires installed in the building thermal envelope shall be sealed m limit air leakage between conditioned and unconditioned spaces.All recessed luminaires shall ba IC-rated and labeled as having mn air leak waurate not more than 2.0 cim(0.944 L/s)when tested in accordance with ASTM E 283 at a 1.57 psf(75 Pa)pressure differential.All recessed luminaires shall be sealed with a gasket or caulk between the housing and the interior wall or ceiling covering. O R403.1.1 Thermostat provision(Mandatory).At least one thermostat shall be provided for each separate heating and cooling system. O R403.1.3 Heat pump supplementary heat(Mandatory).Heat pumps having supplementary electric-resistance heatshall have controls that,except during defrost,prevent supplemental heat operation when the heat pump compressor can meet the heating load. O Soehne(Mandatory)NJI ducts,air handlers,and filter boxes and building cavities that form the primary air containmentpassageways for air distribution systems shall be considered ducts and plenum chambers,shall be constructed and sealed In accordance with Section C403.2.7.2 of the Commercial Provisions of this code and shall be shown to meet duct tightness criteria by post-construction or rough-in testing below. Duct tightness shall be verified by testing m Section mmof the nESNET Standards by either an energy rater certified in accordance with Section u53.an.Florida Statutes,mas authorized by Florida Statutes,toba"substantially leak free"by either of the following: 1. Post-construction test:Total leakage shall ba less than nr equal m4 cln(113Umin)per 1ou square feet(o.2Sm2)uf conditioned floor area when tested ute pressure differential o,n1 inches vuu.(25 Pa)across the entire system,including the manufacturer's air handler enclosure.All register boots shall uu taped m otherwise sealed during the test. } e. Rough-in test:Total leakage shall he less than o,equal to 4 cfm(113 L/min)per 100 square feet(9.29 m2)of conditioned floor area when tested ata pressure differential ufo1 inches w.o.(25Pa)across the system,including the manufacturers air handler enclosure.All registers shall be taped v,otherwise sealed during the test.|f the air handler is not installed at the time of the test,total leakage shall be less than or equal to 3 cfm (uuumN)per 1on square feet(9.2om2)m conditioned floor area. Exceptions: 1. The total leakage test is not required for ducts and air handlers located entirely within the building envelope. z.
