Performance-Based Ordinances

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.

Low-Rise Residential New Construction CALGreen - Voluntary Tiers 1 and 2

Analysis of several options for requiring new single and low-rise multifamily projects to meet CALGreen Tier 1 and Tier 2 specifications using either energy efficiency measures only, or a combination of energy efficiency and photovoltaic systems. This study includes all Climate Zones in California, so is applicable statewide under the 2016 Energy Standards.

Low-Rise Residential New Construction CALGreen Tier 3

Analysis of the feasibility of requiring residential new construction projects to meet the Title 24, Part 11 (CALGreen) Tier 3 energy efficiency performance requirements and, combined with photovoltaic system, achieve a specified Energy Design Rating (EDR) equivalent to the proposed 2019 values. The study maximizes the compliance margin based on energy efficiency measures alone and includes a photovoltaic system to offset site electricity usage. The analysis is based on a mixed-fuel (electricity/natural gas) design, includes all climate zones in California, and is applicable statewide under the 2016 Building Energy Standards.

Low-Rise Residential New Construction: All-Electric Design, CALGreen - Voluntary Tiers 1 and 2

Analysis documenting the technical and economic feasibility of a local ordinance requiring residential new construction projects to meet CALGreen Tier 1 or Tier 2 specifications using an all-electric design and photovoltaic systems to offset site electricity usage. The study examines how results of compliance calculations are impacted depending on the availability of natural gas.

Low-Rise Residential New Construction Zero Net Energy (“Code-ZNE”) and Nonresidential Tier 1 (Santa Monica, Climate Zone 6)

Analysis of the feasibility of requiring residential new construction to meet the Title 24, Part 11 definition of ZNE (15% better than Title 24, Part 6 and achieve an Energy Design Rating, or EDR = 0), and new nonresidential new construction to meet the CALGreen Tier 1 requirements (10% better than 2016 Title 24, Part 6). This study contains content specific to Santa Monica’s policies and is currently only available for Santa Monica in Climate Zone 6.
