Effective from January 1, 2020, the Solar Mandate requires that all new residential buildings, including single-family homes and multi-family buildings up to three stories high, include a solar photovoltaic (PV) system. There are a few exceptions and alternative compliance options, such as community solar or solar-ready provisions, which allow for shared solar systems or the installation of solar panels in the future.
The size of the required solar PV system is based on the dwelling’s total conditioned floor area (CFA), which includes both living space and conditioned non-living space. The required system size is determined by a formula outlined in the code, taking into account factors such as the location of the building and number of dwelling units.
Title 24 provides flexibility in meeting the solar requirements. Developers have the choice in some parts of CA to either install on-site solar PV systems that meet the prescribed size requirements or use alternative compliance methods like community solar or solar-ready provisions.
In addition to the solar PV requirement, Title 24 also includes energy efficiency measures that need to be implemented in new residential construction. These measures focus on various aspects, including lighting, insulation, windows, HVAC systems, and more, to ensure overall energy efficiency in the building.
It’s important to note that these requirements may evolve and change over time. It’s advisable to refer to the most up-to-date version of California’s Title 24 Building Energy Efficiency Standards and consult with professionals like us, who specialize in California’s energy regulations to ensure compliance with the current solar requirements.
Title 24 requirements mandate the inclusion of a minimum number of EV-capable parking spaces and EV-ready parking spaces. EV-capable spaces are designed to have the necessary electrical infrastructure to support future EV charging stations, while EV-ready spaces have the electrical infrastructure and conduit already installed.
Title 24 requires that a certain percentage of parking spaces to have EVSE (level 2 EV Charging stations) as well as a percentage to be EV-capable and EV-ready. The specific percentage varies based on factors such as the unit make-up and the building type.
The requirements specify the minimum electrical capacity and infrastructure needed to support EV charging. This includes provisions for adequate electrical panels, circuits, and conduits to accommodate EV charging stations.
Title 24 also encourages demand management strategies for EV charging. This may involve measures such as load management systems, time-of-use rates, or other approaches to optimize the use of electricity during peak demand periods.
Developers are required to document compliance with the EV charging requirements as part of the overall compliance documentation for Title 24. This may involve providing plans, electrical load calculations, and other relevant information.
It’s important to note that the specific EV charging requirements may vary depending on the building type, size, and other factors. The California Energy Commission, which oversees Title 24, periodically updates these requirements, so it’s essential to consult the most recent version of the standards and stay informed about any changes or updates.
