For SI: 1 pound per square foot = 4.88kg/m2 , 1 pound per cubic foot = 16 kg/m3
ci = Continuous insulation, NR = No requirement, LS = Liner system.
a. Use of Opaque assembly U-factors, C-factors, and F-factors from ANSI/ASHRAE/IESNA 90.1 Appendix A shall be permitted, provided theconstruction, excluding the cladding system on walls, complies with theappropriate construction details from ANSI/ASHRAE/ISNEA 90.1 AppendixA.
b. Opaque assembly U-factors based on designs tested in accordance withASTM C1363 shall be permitted. The R-value of continuous insulationshall be permitted to be added to or subtracted from the original testeddesign.
c. Where heated slabs are below grade, below-grade walls shall comply withthe F-factor requirements for heated slabs.
d. “Mass floors” shall include floors weighing not less than:
1. 35 pounds per square foot of floor surface area; or
2. 25 pounds per square foot of floor surface area where the materialweight is not more than 120 pounds per cubic foot.
e. These C-, F- and U-factors are based on assemblies that are not required tocontain insulation.
f. Evidence of compliance with the F-factors indicated in the table forheated slabs shall be demonstrated by the application of the unheated slabF-factors and R-values derived from ASHRAE 90.1 Appendix A.
Analysis of Code Change: Table C402.1.4 clarifies the use and application of the codes prescriptive building thermal envelope provisions. The updated table modifies the thermal envelope requirements for above-deck roof insulation to be consistent with ASHRAE 90.1. The updated table also corrects U-factor errors for “Mass Walls, Above Grade” for the Climate Zones 1, 2, 3, 4, 5, 6, and 7. New Note b was added to recognize results of hot box laboratory tests conducted in accordance with ASTM C1363 for compliance with the code.

C402.4.1.1 Increased vertical fenestration area with daylight responsive controls.In Climate Zones 1 through 6, not more than 40 percent of the gross above-grade wall area shall be permitted to be vertical fenestration, provided all of the following requirements are met:
1. In buildings not greater than two stories above grade,not less than 50 percent of the net floor area is withina daylight zone.
2. In buildings three or more stories above grade, notless than 25 percent of the net floor area is within adaylight zone.
3. Daylight responsive controls complying with SectionC405.2.3.1 are installed in daylight zones.
4. Visible transmittance (VT) of vertical fenestrationis not less than 1.1 times solar heat gain coefficient(SHGC).
Exception: Fenestration that is outside the scope of NFRC 200 is not required to comply with Item 4.
Analysis of Code Change: This section was revised to increase incentives for daylight zones.
C402.4.1.2 Increased skylight area with daylight responsive controls.The skylight area shall be permitted to be not more than 5 percent of the roof area provided daylight responsive controls complying with Section C405.2.3.1 are installed in daylight zones under skylights.
Analysis of Code Change: The exceptions in this section were deleted.
C402.5.1 Air barriers.A continuous air barrier shall be provided throughout the building thermal envelope. The air barriers shall be permitted to be located on the inside or outside of the building envelope, located within the assemblies composing the envelope, or any combination thereof. The air barrier shall comply with Sections C402.5.1.1 and C402.5.1.2.
Exception: Air barriers are not required in buildings located in Climate Zone 2B.
Analysis of Code Change: The exception has been revised to only exempt air barriers in buildings located in Climate Zone 2B.
C402.5.7 VestibulesBuilding entrances shall be protected with an enclosed vestibule, with all doors opening into and out of the vestibule equipped with self-closing devices. Vestibules shall be designed so that in passing through the vestibule it is not necessary for the interior and exterior doors to open at the same time. The installation of one or more revolving doors in the building entrance shall not eliminate the requirement that a vestibule be provided on any doors adjacent to revolving doors.
Exceptions: Vestibules are not required for the following:
1. Buildings in Climate Zones 1 and 2.
2. Doors not intended to be used by the public, such asdoors to mechanical or electrical equipment rooms,or intended solely for employee use.
3. Doors opening directly from a sleeping unit ordwelling unit.
4. Doors that open directly from a space less than 3,000square feet (298 m2) in area.
5. Revolving doors.
6. Doors used primarily to facilitate vehicularmovement or material handling and adjacentpersonnel doors.
7. Doors that have an air curtain with a velocity of notless than 6.56 feet per second (2 m/s) at the floor thathave been tested in accordance with ANSI/AMCA 220and installed in accordance with the manufacturer’sinstructions. Manual or automatic controls shall beprovided that will operate the air curtain with theopening and closing of the door. Air curtains andtheir controls shall comply with Section C408.2.3.
Analysis of Code Change: C402.5.7 was revised to allow an air curtain with a velocity of not less than 6.56 fps and tested in accordance with ANSI/AMCA 220 to be used as an alternative to a vestibule.

C403.2.4.4 Zone isolationHVAC systems serving zones that are over 25,000 square feet (2323 m2) in floor area or that span more than one floor and are designed to operate or be occupied nonsimultaneously shall be divided into isolation areas. Each isolation area shall be equipped with isolation devices and controls configured to automatically shut off the supply of conditioned air and outdoor air to and exhaust air from the isolation area. Each isolation area shall be controlled independently by a device meeting the requirements of Section C403.2.4.2.2. Central systems and plants shall be provided with controls and devices that will allow system and equipment operation for any length of time while serving only the smallest isolation area served by the system or plant.
Exceptions:
1. Exhaust air and outdoor air connections to isolationareas where the fan system to which they connect isnot greater than 5,000 cfm (2360 L/s).
2. Exhaust airflow from a single isolation area of lessthan 10 percent of the design airflow of the exhaustsystem to which it connects.
3. Isolation areas intended to operate continuously orintended to be inoperative onlywhen all other isolation areas ina zone are inoperative.
Analysis of Code Change: A new section providing the ability to create isolation areas within zones under certain circumstances in order to allow for additional reductions in energy use and operating costs. Criteria is consistent with ASHRAE 90.1.
C403.2.8 Kitchen Exhaust SystemsReplacement air introduced directly into the exhaust hood cavity shall not be greater than 10 percent of the hood exhaust airflow rate. Conditioned supply air delivered to any space shall not exceed the greater of the following:
