Add the following section:
5.201.1.1 Energy performance. [Reserved]
5.201.1.2. Renewable Energy and Better Roofs.
(a) Newly constructed buildings of nonresidential occupancy which are 2000 square feet or greater in gross floor area, are of 10 or fewer occupied floors, and apply for a building permit on or after January 1, 2017 shall install solar photovoltaic systems and/or solar thermal systems in the solar zone required by California Title 24, Part 6 Section 110.10.
(b) The required solar zone area for the project shall be calculated under California of Regulations1
(CCR), Title 24, Part 6, Section 110.10(b) through (e), and Nonresidential Compliance Manual Chapter 9, as provided below:
(1) Buildings subject to Planning Code Section 149 may apply Exception 5 to Title 24, Part 6, Section 110.10(b)1B in the calculation of the minimum solar zone area and may not apply Exceptions 1, 2, 3, and 4 in the calculation.
(2) Buildings not subject to Planning Code Section 149 may apply Exceptions 3 and 5 in the calculation of the minimum solar zone area and may not apply Exceptions 1, 2, and 4 in the calculation. Such buildings with a calculated minimum solar zone area of less than 150 contiguous square feet due to limited solar access under Exception 3 are exempt from the solar energy requirements in this Section 5.201.1.2.
(c) The sum of the areas occupied by solar photo- voltaic collectors and/or solar thermal collectors must be equal to or greater than the solar zone area. The solar zone shall be located on the roof or overhang of the building, or on the roof or overhang of another structure located within 250 feet of the building or on covered parking installed with the building project. Solar photo- voltaic systems and solar thermal systems shall be installed in accord with all applicable state and local code requirements, manufacturer’s specifications, and the following performance requirements:
(1) Solar photovoltaic systems: The total nameplate capacity of photovoltaic collectors shall be at least 10 WattsDC per square foot of roof area allocated to the photovoltaic collectors.
(2) Solar thermal systems: Solar thermal systems installed to serve non-residential building occupancies shall use collectors with OG-100 Collector Certification by the Solar Rating and Certification Corporation (SRCC) or the International Association of Plumbing and Mechanical Officials (IAPMO), shall be designed to generate annually at least 100 kBtu per square foot of roof area allocated to the solar thermal collectors, and, for systems with at least 500 square feet of collector area, shall include a Btu meter installed on either the collector loop or potable water side of the solar thermal system.
(d) Approval by the Planning Department of com- pliance with the Better Roof requirements, including the Living Roof alternative, as provided in Planning Code Section 149, shall be accepted for compliance with San Francisco Green Building Code Section 5.201.1.2(a) through (c). The requirements of CCR Title 24, Part 6, Section 110.10 for the solar zone shall still apply.
(Amended by Ord. 221-16,* File No. 160965, App. 11/10/2016, Eff. 12/10/2016, Oper. 1/1/2017)
CODIFICATION NOTE
*Editor’s note:
Ord. 229-16, File No. 160948, App. 11/22/2016, Eff. 12/22/16, repealed the 2013 San Francisco Green Building Code and enacted the 2016 San Francisco Green Building Code, consisting of amendments to the 2016 California Green Building Standards Code. A related ordinance, Ord. 221-16, File No. 160965, App. 11/10/2016, Eff. 12/12/16, amended the 2016 San Francisco Green Building Code. (See Section 3, para. (c) of Ord. 221-16.) Both ordinances have an operative date of 1/1/17. Since the expressly stated legislative intent is that Ord. 221-16 amend Ord. 229-16, the codifier has used the text of Ord. 221-16 whenever it differs from the text of Ord. 229-16.
