FOFtM R405;2014 ' � ' Florida Department of Business and Professional Regulations Residential Whole Building Performance and Prescri tive Methods ADDRESS: Permit Number: - , w_ Zephyrhills,F�, - , MANCIATORY REQUIREMENTS See individual code sectio�s'for full details. � 401.3 Energy Performance Level(EPL)display card(Mandatory). The building official shall require that an energy performance level(EPL) display card be campleted and certified by the builder to be accurate and correct before fina!approval of the building for occupancy.Florida law [Section 553.9085,Fla�ida Statues]requires the EPC display card to be included as an addendum to each sa(es contract for both presold and nanpresold residential buildings.The EPL display card contains infarmation indicating the energy pertormance level and efficiencies of components installed in a dwelling unit.The building official shall verify that the EPL display card completed and signed by tne builder accurately reflects the plans and specifications submitted ta demonstrate campliance for the building.A capy of the EPl..dsplay card can be€aund in Appendix C � R402.4 Air leakage(Mandatory). The building thermal envelope shall be constructed to limit air leakage in accordance with the requirements of Sections R402.1 thro�gh R402.4.4. Q R402.4.1 Buiiding 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 al(ow for differentia!expansion and cantraction. • R402.4.1.1 installation. The components af the building thermal envelope as listed in Table R402.4 1.1 shall be installed in accordance with the manufacturer's instructions and the criteria listed in Tahle 402.4,1 1,as applioable to the method of construction. Where required by ihe cade afficial,an approved fhird party shall inspect a!1 camponents and verit�t compliance. • R402.4.1.2 7esting. The building or dwelling unit shall be tested and verified as having an air leakage rate of not exceeding 5 air chatages per hour in Giimate Zonas 1 and 2,and 3 air changes per hour in C(imate Zones 3 through 8.Tesfing 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 cpnducted by an approved third party.A written report of the results of the test shall be signed by the party conducting the test and pravided to the code official.Testing shall be performed at any Time after creation of a11 psnetrations of the building thermal envelope. During testing: 1.EMerior windows and daors,fireplace and stove doors shall be closed,but noi sealed,beyo�d ihe intended weatherstripping or other infi(tratian oontrol measures; 2. Dampers including exhaust,intake,makeup air,backdraft and flue dampers shall be closed,but not sealed beyond intended infiltration ca�trol measures; 3.Interior doors,if insta(Ied at the time af the fest,shall be open; 4,Exterior doors for continuous ventilation systems and heat recovery ventilators shail be closed and sealed; 5.Heating and cooling systems,if insialled af Yhe time of the tesi,sha!!be turaed off;and 8,Supply and return registers,if instal(ed at the tirne of the test,shal(be ful(y open. O R402.4,2 Fireplaces. New wood-buming fireplaces shall have tight-fitting flue dampers and outdaor combustion air, O R402.A.3 Fenestration air teakage.Windows,skylights and sliding glass doors shall have an air infiltratinn 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 tested according to NFRC 400 or AAMA/WOMA/CSA 141tI.S.21A440 by an accredited,independent lat�ora#ory and listed and labeled by the manufacturer. Exception: Site-built windows,skylights and doars. O R402.4.4 Recessed lighttng. Recessed luminaires instailed in the building thermal e�velope shall be sealed to limit air leakage between conditioned and unconditioned spaces.All recessed luminaires shall be IC-rated and labeled as having an air leakage rate not more than 2.0 cfm(0.944 lJs)when tested in accordance with ASTM E 283 at a 1.57 psf(75 Pa)pressure differential.Al!recessec! lumi�aires sha11 be sealed with a gaskef or cau[k befween the hausing and the interiar wal(or ceiling cavering. � R403.1.1 Thermostat provision(Mandatory). At least one thermostat shall be provided for each separate heating and cooling system. _ � R903.1.3 Heat gump supplerr�entaty heat(Mandatory}. !-3eat pumps having supplsmenfary e(ectric-resistance heat shai(have controls that,except during defrost,prevent supplemental heat operation when the heat pump compressor can meet the heating load. ' � R443.2.2 SealEng{Mandatary)A!!ducts,air hand(ers,and filter boxes and building cavities thai form the primary air canfainment passageways 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-construc#ion or rough-in tesiing below. Duct tightness shall be verified by testing to u�ection 803 of the RESNET Standards by either an energy rater certified in accordance with Section 553.99,Florida Statutes,or as autharized by Flaida Statutes,to be"substaniially leak free"by either of the fo!lowing: 1. Post-construction test:Tota�leakage shail be less than or equal to 4 cfm (113 Umin)per 100 square feet(9.29 m2)of conditioned floor 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.Ali . register boots shall be teped ar otherwise sealed during the tesi. 2. Rough-in test:Total leakage shall be less than or equal to 4 cfm (113 Umin)p�r 100 square feet(9.29 m2)of oonditioned floor area when tested at a pressure differentiai af 0.1 inches w.g.(25Pa)across the sysierrt,inc(uding the manufac#urer's air handler enclosure.AII registers shall be taped or otherwise sealed during the test.If the air fiand(er is not installed at the iime ofi 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. Exceptians: 1. The total leakage test is not required for ducts and air handlers located entirely within the building envelope. 2. Duct testing is not mandatory for buildings camplying by Sectian R405 of this cade. 10J90t2017 4:19 PM EnergyGaugeC�USA-FlaRes2014 -Section R405.4.1 Gom Page 1 of 3
