2019 Reports and Resources
A “performance-based” ordinance raises the energy efficiency bar above Title 24, Part 6 Energy Standards, and provides project applicants with flexibility about how the bar will be reached. There are several acceptable methods for demonstrating an ordinance is cost-effective, such as:
Customer Cost: Presents the results from a customer perspective, estimating the customer’s savings from reduced energy usage at the site level.
Time Dependent Valuation (TDV): The California Energy Commission’s primary metric for energy savings. TDV accounts for how each unit of energy consumed (particularly electricity) has varying cost to the customer, utility, society, and environment depending on the particular hour of the year it is used.
