Review the respective section for more information. (04/2022) Building Envelope: mmaryApproved rrdli TLPMM�W, ANCE Air Leakage. Manufactured fenestration, exterior doors, and exterior pet doors must limit air leakage t 3 M per square foot or Na- § 110.6(a)1: less when tested per NFRC-400, ASTM E283, or AAMA/WDMA/CSA 101/I.S.2/A440-2011. ' e: § 110.6(a)5: Labeling. Fenestration products and exterior doors must have a label meeting the requirements of § 1 Field fabricated exterior doors and fenestration products must use U-factors and solar heat gain coefficient (SHGC) values from § 110.6(b): Tables 110.6-A, 110.6-B, or JA4.5 for exterior doors. They must be caulked and/or weather-stripped. Air Leakage. All joints, penetrations, and other openings in the building envelope that are potential sources of air leakage must be § 110.7: caulked, gasketed, or weather stripped. § 110.8(a): Insulation Certification by Manufacturers. Insulation must be certified by the Department of Consumer Affairs. Bureau of Household Goods and Services BHGS . § 110.8(g): Insulation Requirements for Heated Slab Floors. Heated slab floors must be insulated per the requirements of § 110.8(g). Roofing Products Solar Reflectance and Thermal Emittance. The thermal emittance and aged solar reflectance values of the § 110.8(i): roofing material must meet the requirements of § 110.8(i) and be labeled per §10-113 when the installation of a cool roof is specified on the CF1 R. § 110.80): Radiant Barrier. When required, radiant barriers must have an emittance of 0.05 or less and be certified to the Department of Consumer Affairs. Roof Deck, Ceiling and Rafter Roof Insulation. Roof decks in newly constructed attics in climate zones 4 and 8-16 area -weighted average U-factor not exceeding U-0.184. Ceiling and rafter roofs minimum R-22 insulation in wood -frame ceiling; or area -weighted average § 150.0(a): U-factor must not exceed 0.043. Rafter roof alterations minimum R-19 or area -weighted average U-factor of 0.054 or less. Attic access doors must have permanently attached insulation using adhesive or mechanical fasteners. The attic access must be gasketed to prevent air leakage. Insulation must be installed in direct contact with a roof or ceiling which is sealed to limit infiltration and exfiltration asspecified in § 110.7, including but not limited to placing insulation either above or below the roof deck or on top of a drywall ceiling. r § 150.0(b): Loose -fill Insulation. Loose fill insulation must meet the manufacturer's required density for the labeled R-value. Wall Insulation. Minimum R-13 insulation in 2x4 inch wood framing wall or have a U-factor of 0.102 or less, or R-20 in 2x6 inch wood § 150.0(c): framing or have a U-factor of 0.071 or less. Opaque non -framed assemblies must have an overall assembly U-factor not exceeding 0.102. Masonry walls must meet Tables 150.1-A or B. § 150.0(d): Raised -floor Insulation. Minimum R-19 insulation in raised wood framed floor or 0.037 maximum U-factor. ; Slab Edge Insulation. Slab edge insulation must meet all of the following: have a water absorption rate, for the insulation material alone § 150.0(f): without facings, no greater than 0.3 percent: have a water vapor permeance no greater than 2.0 perm per inch; be protected from physical damage and UV light deterioration; and, when installed as part of a heated slab floor, meet the requirements of § 110.8(g), Vapor Retarder. In climate zones 1 through 16, the earth floor of unvented crawl space must be covered with a Class I or Class II § 150.0(g)l: vapor retarder. This requirement also applies to controlled ventilation crawl space for buildings complying with the exception to 150.0 d . Vapor Retarder. In climate zones 14 and 16, a Class I or Class II vapor retarder must be installed on the conditioned space side of § 150.0(g)2: all insulation in all exterior walls, vented attics, and unvented attics with air -permeable insulation. Fenestration Products. Fenestration, including skylights, separating conditioned space from unconditioned space or outdoors must have § 150.0(q): a maximum U-factor of 0.45; or area -weighted average U-factor of all fenestration must not exceed 0.45. Fireplaces, Decorative Gas Appliances, and Gas Log: § 110.5(e) Pilot Light. Continuously burning pilot lights are not allowed for indoor and outdoor fireplaces. § 150.0(e)l: Closable Doors. Masonry or factory -built fireplaces must have a closable metal or glass door covering the entire opening of the firebox. § 150.0(e)2: Combustion Intake. Masonry or factory -built fireplaces must have a combustion outside air intake, which is at least six square inches in area and is equipped with a readily accessible, operable, and fight -fitting damper or combustion -air control device. § 150.0(e)3: Flue Damper. Masonry or factory -built fireplaces must have a flue damper with a readily accessible control. Space Conditioning, Water Heating, and Plumbing System: Certification. Heating, ventilation, and air conditioning (HVAC) equipment, water heaters, showerheads, faucets, and all other § 110.0-§ 110.3: regulated appliances must be certified by the manufacturer to the California Energy Commission. § 110.2(a): HVAC Efficiency. Equipment must meet the applicable efficiency requirements in Table 110.2-A through Table 110.2-N. Controls for Heat Pumps with Supplementary Electric Resistance Heaters. Heat pumps with supplementary electric resistance § 110.2(b): heaters must have controls that prevent supplementary heater operation when the heating load can be met by the heat pump alone; and in which the cut -on temperature for compression heating is higher than the cut -on temperature for supplementary heating, and the cut-off temperature for compression heating is higher than the cut-off temperature for supplementary heating. Thermostats. All heating or cooling systems not controlled by a central energy management control system (EMCS) must have a § 110.2(c): setback thermostat. Insulation.
