(a)Fenestration product performance must be certified in accordance with NFRC and requires supporting documentation.
In the following requirements,blank checkboxes identify requirements that the applicant has not acknowledged as being met. Checkmarks
identify requirements that the applicant acknowledges are met or excepted from compliance. 'Plans reference page/section'identifies where in
the plans/specs the requirement can be verified as being satisfied.
Fenestration Product Rating:
6/ 1. U-factors of fenestration products(windows,doors and skylights)are determined in accordance with NFRC 100 by an accredited,
independent laboratory,and labeled and certified by the manufacturer or are determined using the commercial size category values
listed in Chapter 15 of the 2009 ASHRAE Handbook of Fundamentals,Table No.4 and shall include the effects of the window frame.
The temporary label afixed to the fenestration products must not be removed prior to inspection.
Plans reference page/section:A500 Division 8
v 2. Solar heat gain coefficient(SHGC)of glazed fenestration products(windows,glazed doors and skylights)shall be determined in
accordance with NFRC 200 by an accredited,independent laboratory,and labeled and certified by the manufacturer or be determined
using the Solar Heat Gain Coefficients(SHGC)in Chapter 15 of the 2009 ASHRAE Handbook of Fundamentals,Table No.10.The
overall values must consider type of frame material and operator for the SHGC at normal incidence.

v 5. Curtain wall,storefront glazing and commercial entrance doors.Curtain wall,storefront gla ung and cotnnterja11I4e4 s'injing
entrance doors and revolving doors are tested for air leakage in accordance with ASTM E:83.For curtain v►afls aAd Voifrgnt glazing,
the maximum air leakage rate is 0.3 cubic foot per minute per square foot of fenestration aila.Gorcomgieraal glaced&svriiging
entrance doors and revolving doors,the maximum air leakage rate is 1.00 cfm/ft2 of door area.
Plans reference page/section:A403 Division 8
v 6. Building thermal envelope insulation.An R-value identification mark is applied(by manufacturer)to each piece of insulation 12
inches or greater in width.Alternately,the insulation installers have provided a signed,dated and posted certification listing the type,
manufacturer and R-value of insulation installed.Refer to code section for blown or sprayed insulation installation/settling depths and
marker requirements.
✓ 7. Insulation mark installation. Insulating materials are installed such that the manufacturer's R-value mark is readily observable upon
inspection.
✓ 8. Insulation product rating.The thermal resistance(R-value)of insulation has been determined in accordance with the U.S.FTC R-value
rule.
v 9. Installation.All material,systems and equipment are installed in accordance with the manufacturer's installation instructions and the
International Building Code.
10.Outdoor air intakes and exhaust openings.Stair and elevator shaft vents and other outdoor air intakes and exhaust openings integral
to the building envelope shall be equipped with not less than a Class I motorized,leakage-rated damper with a maximum leakage rate
of 4 cfm per square foot at 1.0 inch water gauge when tested in accordance with AMCA 500D.Stair and shaft vent dampers shall be
capable of being automatically closed during normal building operation and interlocked to open as required by fire and smoke detection
systems.
Requirement is not applicable.
Plans reference page/section:
✓ 11.Loading dock weatherseals.Cargo doors and loading dock doors are equipped with weather seals to restrict infiltration when vehicles
are parked in the doorway.
Requirement is not applicable.
Plans reference page/section:
12.Recessed lighting.Recessed luminaires installed in the building thermal envelope are sealed to limit air leakage between conditioned
and unconditioned spaces.All recessed luminaires are IC-rated and labeled as meeting ASTM E 283.All recessed luminaires are
sealed with a gasket or caulk between the housing and interior wall or ceiling covering.
Requirement is not applicable.
Plans reference page/section:
✓ 13.Vestibules.Doors that separate conditioned space from the exterior are protected with an enclosed vestibule,with all doors of the
vestibule equipped with self-closing devices.Vestibules are designed so interior and exterior doors to not operate simultaneously.
Requirement is not applicable.
