Related Measures

• Swimming Pool and Spa Heating

  This proposal includes measures for saving energy on pool heating: mandatory solar heating requirement for pools and spas, exploration of a variable-speed control installation requirement for pool pump systems, clean-up and clarification of existing requirements, and requirements for pool insulation.

• Nonresidential Refrigeration

  The 2025 code cycle refrigeration CASE report will propose a minimum specific efficiency for all non-process cooling/freezing evaporators used in refrigerated warehouses.

• Existing Buildings – No Longer Being Considered for the 2025 Code Cycle

  This proposal addresses multiple provisions that impact the energy performance of existing buildings by examining exceptions that currently apply to alterations. Currently, Title 24, Part 6 has many requirements that are only applicable to new construction. This proposal reviews those existing exceptions and removes or modifies those that are no longer justified due to changes in market conditions and cost analysis.

• Nonresidential and Multifamily Elevators – No Longer Being Considered for the 2025 Code Cycle

  This measure would look to modify or add to Section 120.6(f) in Title 24, Part 6 to incorporate additional mandatory performance requirements for elevators. Efforts would be focused on analyzing the cost-effectiveness of incorporating energy efficiency requirements for elevators in high-rise buildings.

• Nonresidential Daylighting

  The automatic daylighting controls measure would adjust the wattage thresholds for when automatic daylighting controls are required to the skylit, primary sidelit, and secondary sidelit daylit zones.

• Nonresidential Envelope

  This code change proposal includes measures designed to improve building energy performance through envelope-related updates, like requiring vestibules for certain buildings (both new construction and additions) with high-traffic main entrances in all climate zones.

• Nonresidential Laboratory Airflow

  This proposal includes requirements for nighttime set-back controls (or other demand-based controls); alignment with ASHRAE 90.1, section 6.5.7.3 allowing an alternate compliance pathway using exhaust air heat recovery; and a variable fan control on the exhaust fan for reducing fan speeds.

• Nonresidential Cooling Towers

  This proposal includes measures that improve the energy and water efficiency of cooling towers: Investigate code modifications to 1) increase the existing prescriptive efficiency requirements for axial fan, open-circuit cooling towers, and 2) ensure blowdown controls are working properly.

• Nonresidential HVAC Controls

  Title 24 includes aggressive HVAC controls requirements, but they have not been realized often enough in practice. Rather than placing the burden on designers and plans examiners, ASHRAE Guideline 36 moves the process “upstream” to the manufacturer level where the controls are programmed into equipment and savings are automatically realized.

• Nonresidential HVAC Space Heating

  This proposal will seek to improve the energy efficiency of space heating systems in nonresidential buildings. All-electric hydronic designs are becoming more popular as more buildings choose to forego natural gas for space heating. However, as more of these systems are installed, attention must be paid to their efficiency, which this proposal will do.

• Nonresidential Industrial Pipe Insulation & Verification

  This proposal includes one measure related to covered process distribution systems: Industrial Piping Verification.

• Nonresidential Controlled Environment Horticulture

  The Statewide CASE Team proposes to evaluate two Controlled Environment Horticulture (CEH) measures for the 2025 Title 24, Part 6 cycle. CEH includes both greenhouses and indoor growing spaces. The proposed measures aim to save energy and water while maintaining crop quality and yield in both greenhouses and indoor grow facilities.

• Nonresidential Commercial Kitchens UPDATE: DKV is no longer being considered for the 2025 code cycle.

  This proposal covers two measures related to commercial kitchens: demand control kitchen ventilation (DCKV), and all-electric readiness requirements.
