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.

Can a nonresidential building be excluded from a battery storage system?

Four exceptions can exclude nonresidential buildings from the battery storage system requirements: Single-tenant buildings with < 5,000 square feet of conditioned floor area (CFA). For multi-tenant buildings, the battery storage system energy and power capacities are based on tenant spaces > 5,000 square feet of CFA

What are the solar PV requirements for mixed occupancy buildings?

The solar PV requirements apply to buildings where at least 80 percent of the total floor area (conditioned or not) is made up of building types listed in Table 140.10-B, including mixed occupancy buildings. These include: What are the Requirements for Battery Storage Systems?

Does a pre-engineered or self-contained energy storage system need ventilation?

Provisions need to be made for sufficient diffusion and ventilation of any possible gases from the storage device to prevent the accumulation of an explosive mixture. A pre-engineered or self-contained energy storage system is permitted to provide ventilation in accordance with the manufacturer’s recommendations and listing for the system.

Does a battery storage system need a rated usable energy capacity?

No. For compliance with the Energy Code the rated usable energy capacity of the battery storage system in kWh must be used for Equation 140.10-B - PDF. The usable capacity is the battery energy storage capacity in kWh that a manufacturer allows to be used for charging and discharging.

What is required working space in and around the energy storage system?

The required working spaces in and around the energy storage system must also comply with 110.26. Working space is measured from the edge of the ESS modules, battery cabinets, racks, or trays.
