Ceiling and Rafter Roof Insulation. Minimum R-22 insulation in wood -frame ceiling; or the weighted average U-factor must not exceed 0.043.
Minimum R-19 or weighted average U-factor of 0.054 or less in a rafter roof alteration. Attic access doors must have permanently attached
§ 150.0(a):
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 continuous roof or ceiling which is sealed to limit infiltration and exfiltration as specified in § 110.7, including but not limited
to placing insulation either above or below the roof deck or on top of a drywall ceiling.*
§ 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 20 inch wood framing wall or have a U-factor of 0.102 or less (R-19 in 2x6 or 1-1-factor of 0.074 or
§ 150.0(c):
less). Opaque non -framed assemblies must have an overall assembly U-factor not exceeding 0.102, equivalent to an installed value of R-13 in a
wood framed assembly.*
§ 150.0(d):
Raised -floor Insulation. Minimum R-19 insulation in raised wood framed floor or 0.037 maximum U-factor.'
§ 150.0(f):
Slab Edge Insulation. Slab edge insulation must meet all of the following: have a water absorption rate, for the insulation material alone without
facings, no greater than 0.3%; have a water vapor permeance no greater than 2.0 perm/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 1-16, the earth floor of unvented crawl space must be covered with a Class I or Class II vapor retarder. This
§ 150.0(9)1:
requirementalso applies to controlled ventilation crawl space for buildings complying with the exception to § 150.0(d).
§ 150.0(g)2:
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 all
insulation in all exterior walls, vented attics, and unvented attics with air -permeable insulation.
150.0
§ (q)'
Fenestration Products. Fenestration, including skylights, separating conditioned space from unconditioned space or outdoors must have a
maximum U-factor of 0.58; or the weighted average 1-1-factor of all fenestration must not exceed 0.58'
Fireplaces, Decorative Gas Appliances, and Gas Log Measures:
§ 150.0(e)lA:
Closable Doors. Masonry orfactory-built fireplaces must have a closable metal or glass door covering the entire opening of the firebox.
§ 150.0(e)1 B:
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 tight -fitting damper or combustion -air control device'
§ 150.0(e)l.C:
Flue Damper. Masonry or factory -built fireplaces must have a flue damper with a readily accessible control'
§ 150.0(e)2:
Pilot Light. Continuous burning pilot lights and the use of indoor air for cooling a firebox jacket, when that indoor air is vented to the outside of
the building, are prohibited.
Space Conditioning, Water Heating, and Plumbing System Measures:
§ 110.0-§ 110.3:
Certification. Heating, ventilation and air conditioning (HVAC) equipment, water heaters, showerheads, faucets, and all other regulated
appliances must be certified by the manufacturer to the Energy Commission'
§ 110.2(a):
HVAC Efficiency. Equipment must meet the applicable efficiency requirements in TABLE 110.2-A through TABLE 110.2-K.'
Controls for Heat Pumps with Supplementary Electric Resistance Heaters. Heat pumps with supplementary electric resistance heaters
§ 110.2(b):
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.*
§ 110.2(c):
Thermostats. All unitary heating or cooling systems not controlled by a central energy management control system (EMCS) must have a
setback thermostat.'
Water Heating Recirculation Loops Serving Multiple Dwelling Units. Water heating recirculation loops serving multiple dwelling units must
§ 110.3(c)5:
meet the air release valve, backflow prevention, pump priming, pump isolation valve, and recirculation loop connection requirements of §
110.3(c)5.
§ 110.3(c)7:
Isolation Valves. Instantaneous water heaters with an input rating greater than 6.8 kBTU/hr (2 kW) must have isolation valves with hose bibbs
or other fittings on both cold water and hot water lines of water heating systems to allow for water tank flushing when the valves are closed.
§ 110.5:
Pilot Lights. Continuously burning pilot lights are prohibited for natural gas: fan -type central furnaces; household cooking appliances (appli-
ances without an electrical supply voltage connection with pilot lights that consume less than 150 Btu/hr are exempt); and pool and spa heaters.'
Building Cooling and Heating Loads. Heating and/or cooling loads are calculated in'accordance with ASHRAE Handbook, Equipment
§ 150.0(h)1:
Volume, Applications Volume,.and Fundamentals Volume; SMACNA Residential Comfort System Installation Standards Manual; or ACCA
Manual J using design conditions specified in § 150.0(h)2.
