However, the 5th Edition ofthe FBCEC has added three newprovisions (Section C406), one ofwhich must also be chosen. The totalbuilding performance compliancepath remains, although instead of theproposed design having an annualenergy cost less than the standardreference design building, thatcriterion has been reduced to 85% ofthe standard reference designbuilding (although the provisions in506.3 of the 2010 FBCEC have notbeen similarly changed in SectionC407.3 of the 5th Edition of theFBCEC).Added a new subsection to providethat additions, alterations, and

Added reference to newprovision that daylighting controlsspecified in Section C402.3 mustsatisfy the lighting section of theFBCEC (Section C405).The percentage limit of verticalfenestration area as a function ofabove-grade wall area has beenchanged to 30% and the percentagelimit of skylight area as a function ofroof area remains unchanged at 3%.New provisions have been addedthat allow the 30% to increase to

Exceptions aremade depending on climate zone,lighting power densities, blockage ofdirect sunlight on the roof, and areaswhere the daylight zone is more than50% of the enclosed floor area.All lighting in the daylighting zonemust be controlled by multi-levelcontrols that comply with SectionC405.2.2.3.3. Exceptions are madedepending on climate zone, lightingpower densities, blockage of directsunlight on the roof, and areas wherethe daylight zone is more than 50%of the enclosed floor area.Skylights in certain areas (e.g.,

An exception is madefor skylights using baffles or skylightgeometry to exclude direct sunlightfrom entering the area.All Florida-specific requirements havebeen deleted and replaced with thebase code criteria. Reference toTables 502.1.1.1(1) and 502.1.1.1(2)have been deleted and replaced withreference to new Table C402.3. Forwindows and glass doors havingdifferent PF values, the option ofusing an area-weighted PF value hasbeen removed. Each must beevaluated separately.New table that’s part of severalchanges and new tables resultingfrom Florida-specific requirementsbeing deleted and replaced with thebase code requirements.Added new provisions to allow forthe adjustment of maximumallowable fenestration SHGC valuesupwards based on projection factorand orientation of the fenestration.There will be an SHGC maximum of0.40 for all windows that are entirelyplaced at least 6 ft above thefinished floor in Climate Zones 1-3.Skylights above daylighting zonesthat have automated control systemswill have a maximum SHGC of 0.60in Climate Zones 1-6.Skylights above daylighting zonesthat have automated control systemswill have a maximum U-factor of 0.90in Climate Zones 1-3 and 0.75 in

Area-weightedaveraging of dynamic glazingtogether with non-dynamic windowswill not be permitted.Area-weighted U-factors are onlypermitted for windows within thesame product category (e.g.,operable windows and fixed windowscannot be calculated together to findarea-weighted averages).Revised the air leakage provisionsby adding provisions for air barriers,adding more detail on air leakageassociated with doors and accessopenings, and revised provisionsassociated with fenestration airleakage, vestibules, and recessedlighting.The thermal building envelope mustprovide a continuous air barriereither inside, outside, or within theenvelope assemblies or anycombination thereof. Specifics aregiven in the next several sections.Exception: Climate Zones 1-3.The continuous air barrier isexpected to be: (1) across all jointsand assemblies; (2) sealed at jointsand changes of position or materials;and (3) compliant with SectionC404.2.8 where the barrier ispenetrated (recessed light fixtures,etc.). However, buildings complyingwith Section C402.4.1.2.3 areexempt from (1) and (3).

Two particular assemblies—coated concrete masonry walls and aPortland cement/sand parge—needonly comply with Section C402.4.1.1.The completed building envelope airleakage should not exceed 0.40cfm/ft² for a pressure differential of75 Pa in accordance with ASTM E779 or an equivalent methodapproved by a code official.Deleted the provisions from the2010 FBCEC and replaced themwith a table that lists the maximumallowable air infiltration rates forfenestration.
