Roof construction that has a thermal mass over the roof membrane, including areas of vegetated (green) roofs, weighing at least 25 pounds per square foot. 99.04.106.5.1. Solar Reflectance. Roofing material shall have a minimum three-year aged solar reflectance equal to or greater than the values specified in LAMC Tables 99.04.106.5.1 and 99.04.106.5.2. Solar reflectance shall be determined by testing by an approved agency in accordance with ASTM C1549, ASTM E1918 or CRRC-1. Solar reflectance values shall be based on the aged reflectance value of the roofing product or the equation in California Green Building Standards Code (CALGreen) Section A4.106.5.1 if aged solar reflectance values are not available. (Amended by Ord. No. 187,208, Eff. 11/5/21.) 99.04.106.5.2. Thermal Emittance. Roofing materials shall have an emittance value equal to or greater than those specified in LAMC Tables 99.04.106.5.1 and 99.04.106.5.2. Thermal emittance shall be determined by testing by an approved agency in accordance with ASTM C1371, ASTM E408 or CRRC-1. (Amended by Ord. No. 187,208, Eff. 11/5/21.) 99.04.106.5.3. Solar Reflectance Index. Roofing materials shall have a three-year aged Solar Reflectance Index equal to or greater than those specified in LAMC Tables 99.04.106.5.1 and 99.04.106.5.2. Aged Solar Reflectance Index (SRI) may be calculated using the SRI Calculation Worksheet (SRI-WS) developed by the California Energy Commission or in compliance with ASTM E1980-01 as specified in the 2019 California Energy Code. Solar reflectance values used in the SRI-WS shall be based on the aged reflectance value of the roofing product. Certified thermal emittance used in the SRI-WS may be either the initial value or the aged value listed by the Cool Roof Rating Council. (Amended by Ord. No. 187,208, Eff. 11/5/21.)

Reduction of Heat Island Effect for Nonroof Areas [N]. Reduce nonroof heat islands for 50% of pathways patios, driveways or other paved areas by using one or more of the methods listed. 1. Use trees or other plantings to provide shade and that mature within 15 years of planting. Trees shall be suitable in mature size and environmental requirements for the site. Tree selection and placement shall consider location and size of areas to be shaded, location of utilities, views from the structure, distance to sidewalks and foundations, overhangs onto adjacent properties and streets; other infrastructure and adjacent to landscaping. In addition, shading shall not cast a shadow, as specified, on any neighboring solar collectors pursuant to California Public Resources Code Section 25981, et seq. (Solar Shade Control Act); 2. Use high albedo materials with an initial solar reflectance value of at least .30 as determined in accordance with American Society for Testing and Materials (ASTM) Standards E1918 or C1549; 3. Use open grid pavement system or pervious or permeable pavement system; 4. Use solar panel arrays to create a canopy shade system; or 5. Other methods of reducing heat island effects acceptable to the Department. 99.04.106.8. All-Electric Buildings. (Added by Ord. No. 187,714, Eff. 1/23/23.) All newly constructed buildings shall be all-electric buildings. EXCEPTIONS: 1. Application for a building permit is submitted, accepted by the Department of Building and Safety, and building permit application fees are paid prior to April 1, 2023. 2.

Gas-powered emergency life-safety systems, including emergency backup. 99.04.106.8.1. Requirements for Combustion Equipment. (Added by Ord. No. 187,714, Eff. 1/23/23.) Where required by Section 99.04.106.8, the electrical infrastructure shall be installed to accommodate the future installation of an electrical heating or cooking appliance/equipment in the following ways: 1. Branch circuit wiring, electrically isolated and designed to serve all electrical heating and cooking appliances in accordance with manufacturer requirements and the California Electrical Code, including the appropriate voltage, phase, minimum amperage, and an electrical receptacle or junction box within 5 feet of the appliance that is accessible with no obstructions. Appropriately sized conduit may be installed in lieu of conductors; and 2. Labeling of both ends of the unused conductors or conduit shall be with "For Future Electrical Appliance/Equipment"; and 3. Reserved circuit breakers in the electrical panel for each branch circuit, appropriately labeled (e.g., "Reserved for Future Electric Range/Equipment"), and positioned on the opposite end of the panel supply conductor connection; and 4.
