• Nonresidential Steam Trap Monitoring

  The proposal for the steam traps monitoring code change requires mandatory automatic monitoring equipment in new construction, and additions and alterations for large installations of all steam trap types. The change impacts all industries using steam traps from oil and gas producers to food processing, hospitals, and universities. The site installation size limits proposed are intended to trigger the code for sites that will be installing a significant number of steam traps and thereby generate a significant savings potential while allowing the smaller users to operate using manual inspection and monitoring methods which are more suited to their specific usage groups.

• Nonresidential Pipe Sizing and Leak Testing for Compressed Air Systems

  The Statewide CASE Team is proposing to require standardized compressed air distribution piping design for the minimization of frictional losses and resulting excessive compressor discharge pressure setpoints. The Statewide CASE Team is proposing to require leak detection and metering of compressed air systems as part of the commissioning of new systems and new sections of piping as well as for ongoing operations in a plant.

• Nonresidential Controlled Environment Horticulture

  The Statewide CASE Team proposes to evaluate indoor horticulture measures for inclusion in the 2022 update cycle of Title 24, Part 6, Building Energy Efficiency Standards. The proposed measures aim to save energy and water, while maintaining product quality and production volume for crops grown in non-stacked and stacked indoor farms. The Statewide CASE Team will consider the plant growth requirements for the following crops in the evaluation of the proposed measures: cannabis, microgreens, vegetable transplants, basil (representing herbs category), lettuce (representing leafy greens category), tomatoes (representing vine plants category), and roses. 

• Nonresidential Refrigeration System Opportunities

  The California Energy Code (Title 24, Part 6) currently includes mandatory efficiency requirements for refrigeration systems serving refrigerated warehouses and retail spaces with walk-in coolers or freezers or refrigerated display cases. This measure proposes code change proposals that will improve energy performance end reduce greenhouse gas (GHG) emissions from refrigeration systems in refrigerated warehouse, retail stores, and commercial kitchens. Requirements for commercial kitchens would apply to a variety of building types including restaurants, schools, and hospitals. 

• Nonresidential Drain Water Heat Recovery

  This measure would prescriptively require drain water heat recovery (DWHR) in nonresidential buildings types that are found to be cost-effective, as well as add DWHR as a compliance option for all nonresidential buildings. This CASE topic builds on a DWHR measure for low-rise residential in Title 24 2019 as a compliance credit and an alternative prescriptive path for gas storage water heaters, heat pump water heaters, and solar water-heating systems.

• Nonresidential Reduce Infiltration

  This CASE Report for reduced infiltration will introduce air tightness elements to the California building energy code since building air leakage testing is currently not a part of mandatory California building codes. This will help demonstrate compliance with the code by investigating two submeasures: air leakage testing and vestibule air leakage.

• Nonresidential Outdoor Lighting Sources

  This CASE Report for outdoor lighting consists of three submeasures: nonresidential lighting zone reclassification, nonresidential lighting power allowances for parking lots, and multifamily outdoor lighting power allowances.

• Nonresidential Indoor Lighting

  This CASE Report for nonresidential indoor lighting consists of two submeasures: networked lighting controls and update lighting power densities.

• Nonresidential High Performance Envelope

  This CASE Report for high performance envelope consists of five different submeasures: opaque envelope performance, roof alterations,  thermal bridging, cool roofs, and high performance windows.

• Nonresidential Grid Integration

  The focus of the nonresidential grid harmonization CASE Report is to adjust the demand response control requirements so buildings that comply with Title 24, Part 6 are more likely to use their controls to participate in demand response events, including pricing events.

• Nonresidential Daylighting

  This CASE Report will use a comprehensive approach to daylighting design and control strategies that maximize the use of natural light while minimizing glare and solar heat gain.

• Nonresidential HVAC Controls

  This CASE Report will further expand on economizer requirements as one submeasure and will include two additional HVAC submeasures related to HVAC controls. In total, this CASE Report will include three submeasures as described below.

• Nonresidential High Efficiency Boilers and Service Water Heating

  This CASE Report will include two submeasures: high efficiency boiler systems and high efficiency service water heating equipment systems. Specifically, these submeasures will update the boiler efficiency and service water heating system requirements to harmonize with the requirements proposed for Addendum BC to ASHRAE Standard 90.1-2016 and section 7.5.3 of ASHRAE Standard 90.1-2016 respectively.

• Nonresidential Computer Room Efficiency

  The data center efficiency CASE Report will improve energy performance of data centers by pursuing the package of code change proposals listed below.

• Nonresidential Air Distribution

  This CASE Report will reduce the energy consumption of space conditioning fan systems in nonresidential buildings by both reducing static pressure in air ducts and adding a new metric that allows for more efficient fan selections. This includes three submeasures: high performance ducts/updates to fan power limits, improved fan efficiency metric, and expand duct leakage testing.
