Whole Buildin Performance and Prescri tive Methods I ADDRESS: Permif Number: Dade City,FL, � iVIANDATC}RY REQUiREMENTS�ee individual code sections for fu11 details. E7 401.3 Energy Performance Levet(EPL}dispiay card(Mandatory}, The buitciing officia!sha{!reqvire that an energy perfarmance ievei{EP�} disptay card be campteted and certified by the builder io be accurate and correct before final approval of the building for occupancy.Florida law (Section 553.9085,Florida 5tatuesJ requires the EPL display card to be included as an addendum to each sales contract for both presold and nanpresoid residentiai buildings.The EPL display card confains information indicating the energy per€ormance level and efticiencies of components instai(ed in a dweEling uniE.The building afficial shall verify that the 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 C. � RA02.4 Air leakage(Mandatory). 7he building thermal envelope shall be constructed to(imit air leakage in accordance wifh the requirements of Sections R402.1 through R402.4.4 p R402.d.1 Bu3lding thermat envelope, The building thermal envelope shall comply with Sections R402:�3 1 and-R4Q2.-4:1.2.-The sealing methads between dissimilar materials shall a!!ow for differentia!expansian and contraction. • EZ402.4.1.1 instatlatian.The components of the building therma!envelope as listed in Table R402.4.1.1 sha!!be installed In ' accordence with the manufacturer's instructians and the criteria listed in 7able 402.4.1,1,as applicable to the method of construction. Where required by the code officiai,an approved third party shai!inspecf alI camponents and verify compliance. • R402.4.1.2 Testing. The buitding or dweiiing unit sha(i be tested and verified as having an air leakage rate of not exceeding 5 air changes per hour in Climate Zones 1 and 2,and 3 air changes per hour in C(imate Zones 3 khrough 8.Testing shal!be conducted with ( a blower door at a pressure of 0.2 inches w.g.{50 Pascals).Where required by the code official,testing shall be conducked by an i approved third party.A written reporl of the resulis of tfie test shali be signed by the party conducting the tesf and provided fa the cade afficial.Testing shall be performed at any time after creation of aSi penefrations af the building thermai envelope. During testing: 1 Exterior windows and daors,fireplace and stove doors sha!!be closed,but not sealed,beyond the intended weatherstripping ar other infiltration control measures; 2.C}ampers inciuding exhaust,intake,makeup air,backdraff and flue dampers shali be closed,but nof sealed beyand intended infiltration contro!measures; 3.Interior doors,if installed at the time of the test,shall 6e open; 4.Exterior doors for continuous ventilation sysfems and heaf recovery ventilators sha11 be closed and sealed; 5.HeaCing and cooling systems,if installed at the time of the test,sha!!be turned off;and I 6.Supply and retum registers,if installed at the time of the test,shali be fuliy open. i 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 leakagelNindows,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 sguare foot(2.8 tlstm2},when tested accarding to NFRC 404 or � AAMAlWDMFttGSA 109lLS.2lA440 by an accredited,independent labaratory and lisked and labeled by the manufacturer. Exceptian: Site-built windows,skylights and doors. O R402.4.4 Recessed tighf3ng. Recessed luminaires instailed in the building therma!envelope shall be sealed to fimit air leakage between conditioned and uncanditioned spaces.All recessed luminaires shall be IC-rated and labeled as having an air leakage rate not more than 2.q cfm(0.944 Us)when tasted in accordance with ASTM E 283 at a 9.57 psf(75 Pa}pressure differentiat.Ai1 recessed luminaires shati be sealed wiYh a gasket or cau(k between Ehe housing and the inieriar wall or ceIling covering. � R4d3.9.1 Thermostat provision(Mandatory}.Af least ane thermostat shali be pravided for each separate heating and caoling system. � R4d3.1.3 Heat pump sugplemenfary heat(Mandatory}.Neaf pumps having suppiementary electrio-resistance heat shall have controls thaf,except during defrost,prevent supplemental heat operation when the heat pump compressor can meet ihe heating load. � R4U3.2.2 SealIng{Mandatory}1A ducts,air handlers,and filter boxes and 6uilding cavities that form the primary air containment passageways for air distribution systems shall be considered ducts and plenum chambers,sfiail be constructed and seated in accordance with Section C4d3.2,7.2 of the Cammercla!Pravisions of ihis cade and sha!!be showr�to mee2 duct tightness criteria hy post-construciian ar raugh-in testing below. Duct tightness shall be verified by testing to Section 803 of the RESNET Standards by either an energy rater certified in accordance with Section ' 553.99,Florida Stafutes,or as authorized 6y�Iorida Statutes,to be"substantiatty leak free"by either of the foltowing: i 1 post-construction test:Total leakage shall be iess than or equal to 4 cfm(113 Umin}per 100 square feet(9.29 m2}of conditioned floor area when fested a#a pressure diiierentiai of 4.1 inches w_g.{25 Pa}across the entire system,including the manufacturer's air handSer enclosure.Ati register boots sha!!be taped or othenvtse sealed during the test. 2. Rough-in tesk:Totai leakage shal!be less t�an or equa!to 4 cfm{113 Urnin)per 900 square feet(9.29 m2)of conditioned floor area when tested at a pressure differential of 0.1 inches w.g.(25Pa)across the system,including the manufacturer's air handler enclosure.All registers shall be taped or othenvise sealed during the test.If the air handter is�ot insta)Ied at the time of the test,totai leaKage shalC be less fhan or equal to 3 cfm (85 Umin)per 104 sguare feet{9.29 m2)of conditioned floor area. ExcepUons: 1. The talal leakage tesi ls not required for ducts and air handlers located entirely withln the bullding envelope. 2. Duct testing is not mandatory for buildCngs complying by Section R4Q5 of thls code. 9!7l2017 7:51 AM EnergyGauge(�USA-FlaRes2Q14 -Section R405.4.1 Com Page 1 of 3
