7.A. - Page 39 of 285 <br />Install alternative plumbing piping to permit the discharge from the <br />clothes washer and all showers and bathtubs to be used for an <br />irrigation system in compliance with the California Plumbing Code <br />and any applicable local ordinances; or <br />iv. Install a rainwater catchment system designed to comply with the <br />California Plumbing Code and any applicable local ordinances, and <br />that uses rainwater flowing from at least 65 percent of the available <br />roof area. <br />B. Meet the Title 24, Part 11, Section A4.106.8.2 requirements for electric <br />vehicle charging spaces. <br />EXCEPTION 5 to Section 110.10(b) 1 B: Buildings where the roof is designed <br />and approved to be used for vehicular traffic or parking or for a heliport. <br />EXCEPTION 6 to section 110.10(b) 1 B: Performance equivalency approved <br />by the Building Official. <br />2. Azimuth. All sections of the solar zone located on steep -sloped roofs shall <br />be oriented between 90 degrees and 300 degrees of true north. <br />3. Shading. <br />A. No obstructions, including but not limited to, vents, chimneys, <br />architectural features, and roof mounted equipment, shall be located in <br />the solar zone. <br />B. Any obstruction, located on the roof or any other part of the building that <br />projects above a solar zone shall be located at least twice the distance, <br />measured in the horizontal plane, of the height difference between the <br />highest point of the obstruction and the horizontal projection of the <br />nearest point of the solar zone, measured in the vertical plane. <br />EXCEPTION to Section 110.10(b) 3: Any roof obstruction, located on the <br />roof or any other part of the building that is oriented north of all points on the <br />solar zone. <br />C. The solar zone needs to account for Shading from obstructions that may <br />impact the area required in 110.10(b) 1B. When determined by the <br />Building Official that conditions exist where excessive Shading occurs <br />and solar zones cannot be met, a performance equivalency approved by <br />the Building Official may be used as an alternative. <br />4. Structural design loads on construction documents. For areas of the roof <br />designated as solar zone, the structural design loads for roof dead load and <br />roof live load shall be clearly indicated on the construction documents. <br />REV: 01-08-20 RL <br />Page 9 of 15 <br />291 <br />
