FOf2M R405-2014 ' Florida Department of Business and Professional Regulations Residential Whole Buildin Performance and Prescri tive Methods ADDRESS: Permit Number: Dade C�ty,FL, iVIANDATORY E2EQUIRIEMENT$See individua(cade sections for fu(I details. � 401.3 Energy Performance Levet(EPL}display card(Mandatoryj. The buil8ing afficial shali require that an energy pe�farmance levei{EPL} display card be comp2eted and certified by the builder to be accurate and correct before fina!approval of the building for occupancy.Florlda law (Section 553.9p85,Florida Statues]requires the EPL display card to be included as an addendum to each saies contract for both presotd and nonpresoid residentiat buildings.The EPL disptay card confains information indicating ihe energy performance level and efficiencies af camponents installed in a dwei(ing unit.The t�ui{ding o�cial shaN verify that ilie EPL display card completed and signed by the builder accurately reflects the plans and specifications submitted to demonstrate compliance for the building.A copy of the EPL display card can be found in Appendix e. � R402.A Air leakage(Mandatory). The building lhermal envelope shall be cansfructed fo limit air leakage in accordance with the raquirements of Sections R402.1 through RA02.4.4. p R402.4.1 Building thermai enve)ope. The building thermal envelope sha11 comply wiih Sections R402.-4:9 1 a-5i'd-R442.-4:i:2.—The sealing methods between dissimilar materials shal!atlow for differential expansian and contraction. � R402.4.1.9 lnstat(ation.The campanents af the building thermat envelope as listed in 7able R4Q2.4.1.1 shall be installed in accordance with ihe manufacturer's instructians and the criteria listed in Table 402.4.1.1,as applicable to ihe meihod of construction. Where required by the code officiai,an approved third party shail inspect aA campanenfs and verify compliance. • 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 cfianges per haur in Ciimate Zones 1 and 2,and 3 sir changes per hour in G{imate Zones 3 through 8.Testing shal!be conducted wllh a biowar daor at a pressure of 0.2 inches w.g.{50 Pascals).Where required by the code official,tes6ng shall be conducted by an approved third party.A written repor#of the results of the tesi shall be signed by the party conducfing the tesf and provided ta the code official.Testing shali be perfarmed at any time after creation of a!i penetrations af#he building therma!envelope. During testing: 1.Exterior w{ndows and daors,fireplace and stove doors shaU be closed,but not sealed,beyond the intended weatherstripping ar other infiltration control measures; 2.Dampers inciuding exhaust,intake,makeup air,backdraB and ttue dampers sha!!be closed,but not sealed beyond infended infiltration contro(measutes; 3.Interior doors,if installed at the time of the test,shall be open; 4.Exterior doors for continuous ventitation systems and heat recovery ver�tilafars shali be closed and sealed; 5.Heafing and cooling systems,if installed at fhe time of the test,sha!!be turned off;and 6.Supply and return registers,if installed at the time of the test,shall be fully apen. O l2402.4.2 Fireplaces.New wood-burning fireplaces shall have tight-fitting flue dampers and outdoor combusiion air. O R402.4.3 Fenestration a3r leakage!/Uindows,skylights and sliding glass doors shall have an air infiltration rate of no more than 0.3 cfm per square foot(1.5 Lls/m2),and swinging doors na more than 0.5 cfm per square faot(2.6 Uslm2},when tested according ta NFRC 4d0 or AAMAIWDMAlGSA 10111.S.21A440 by an accredited,independent lahoratory and tisted and labeled by the manuPacturer. Exception: Site-built windows,skylights and doors. O R402.4.4 Recessed lighting. Recessed luminaires instailed in the building thermai envelape sha!!be sealed to lim3t air leakage between condiUoned and uncanditioned spaces.AII recessed luminaires shall be IC-rated and labeled as having an air leakage rate not more than 2.0 cfm(0.944 L/s}when tested fn accordance with ASTM E 283 at a 1.57 psf(75 Pa}pressure differenfial.Ai)recessed luminaires shal!he sealed wifh a gasltet or caulk between the housing and the interior wall oc ceiling cavecing. � R403.1.1 Thermostat provlsion{Mandatory}.At least one thermasiat shaJi be pravided for each separate heating and coaling system. � R403.1.3 Neat pump supplemenfary heat{14tlandatory}.Heai pumps hauing sugplementary electric-resistance heat shalf heve controls that,except during defrost,prevent supplemental heaf operation when the heat pump compressor can meet the heating load. � R403.2.2 Sealing{Mandatory}?II ducts,air handlers,and filter boxes and building cavities that form the primary air containment passageways for air distribution systems shall be considered ducts and plenum cfiambers,shail be consfructed and sealed in accordance with Section C403.2.7.2 of fhe Commercia!Provisions af this cade and shaii be shown to meei duct tighiness criferia by post-construction ar rough-in festing below. Duct tightness shall be veritJed by testing to Section 803 of the RESNET Standards by either an energy rater certified in accordance with Section 553.99,Florida Sta#utes,or as autharized 6y Florida Statutes,to be"substantialty leak free"by either of the following: 1 Post-construction test:Total leakage shall be Iess ihan or equal to 4 cfm(113 Vmin)per 100 square feet(9.29 m2}of conditioned 8oar area whe�tested af a pressure differen#ial of�.7 inches w_g.{25 Pa}actass the entire system,including fhe manufacturer's air hand(er enc{asure.A!{ register boots shall be taped or oiherwIse sealed during the test. 2. Rough-in test:Totai leakage shall be tess than or equal ta 4 cfm{113 Llmin)per 100 square feet(9.29 m2)of conditioned floor area when tested ai a pressure differential of 0.1 inches w.g.(25Pa)across the system,including#he manufacturer's air handler enclosure.A(1 registers shall 6e taped or otherwise sealed dueing fhe test.)f the air handter is not instalied at the time of the test,tofal leakage shall be less than ar equai ta 3 cfm {85 Limin}per 9d0 square ieet(9.29 m2}af conditianed floor acea. F�cce{rtions: 'f. The totai leakage test ls not cequired for ducts and air handlers located entirely within ihe bullding envelope. 2.
