Which building types require a photovoltaic (PV) system?

All newly constructed building types specified in Table 140.10-A, or mixed occupancy buildings where one or more of these building types constitute at least 80 percent of the floor area of the building, shall have a newly installed photovoltaic (PV) system meeting the minimum qualification requirements of Reference Joint Appendix JA11.

Does a building need a battery storage system?

All buildings that are required by Section 140.10 (a) to have a PV system shall also have a battery storage system meeting the minimum qualification requirements of Reference Joint Appendix JA12. The rated energy capacity and the rated power capacity shall be not less than the values determined by Equation 140.10-B and Equation 140.10-C.

Do I need a PV system for a Sara?

Exception 2 to Section 140.10 (a): No PV system is required where the required PV system size is less than 4 kW dc. Exception 3 to Section 140.10 (a): No PV system is required if the SARA contains less than 80 contiguous square feet.

What is PV size in kW DC?

The PV size in kW dc shall be not less than the smaller of the PV system size determined by Equation 140.10-A, or the total of all available solar access roof area (SARA) multiplied by 14 W/ft 2.

How do I determine the battery capacity of a building?

Where the building includes more than one of the space types listed in Table 140.10-B, the total battery system capacity for the building shall be determined by applying Equations 140.10-B and 140.10-C to each of the listed space types and summing the capacities determined for each space type and equation.
