The California Energy Commission (CEC) estimates that new updates to Title 24 may add 280 MW of annual solar capacity as well as 400 MWh of energy storage to supplement California’s aging electric grid. Title 24 is part of the CEC’s Building Energy Efficiency Standards that requires all new commercial and mixed-use developments to obtain a minimum required amount of solar PV and storage based on a facility’s Climate Zone and conditioned floor area. 

Use Stem’s Title 24 Calculator to Gain the Most Value 

Stem has developed an easy-to-use tool to help you determine your specifications for Title 24 and how to gain the most value out of this new requirement. 

Stem’s Title 24 Calculator only requires three inputs: reusable square footage of the building, zip code, and building type. (The Calculator has a drop down list of all building type options.) 

After providing this information, our Calculator determines your Climate Zone, the solar PV capacity factor, the minimum required solar capacity, the minimum battery capacity, and the rated power capacity requirement.

When you share your results with Stem, we work with you to determine the best battery size (not just the minimum) for your building. This means you gain the most value based on other possible battery use cases – such as integrating with charging stations for an electric vehicle fleet, optimizing energy capacity for a large facility, or adding backup power to increase resilience. All of these use cases are applicable for C&I facilities like hospitals, arenas, warehouses, factories, campuses, and office buildings. Regardless of your facility type, Stem will help size a battery that fits your business needs to achieve the most value.
