Title 24 Non-Residential Envelope Compliance in California

Understanding Title 24 for Non-Residential Buildings

Title 24 Non-Residential energy standards ensure that commercial buildings in California meet strict energy efficiency requirements. These regulations cover:

  • Insulation

  • Fenestration (windows, skylights, and glass doors)

  • Air leakage City Scape

  • Overall building envelope performance

Our Title 24 Non-Residential compliance reports provide the necessary documentation for building permit approval, ensuring your project meets all California Energy Commission (CEC) requirements.

Title 24 Non-Residential Envelope Requirements

Insulation and Thermal Performance

Title 24 sets specific insulation rules for:

  • Walls

  • Roofs

  • Floors

  • Doors

These requirements vary based on California’s climate zones. Proper insulation helps:

  • Reduce heat transfer

  • Improve indoor comfort

  • Lower energy costs for heating and cooling

Fenestration Standards: Windows, Skylights, and Glass Doors

Title 24 limits U-factor and Solar Heat Gain Coefficient (SHGC) values to optimize energy efficiency.

  • U-factor: Measures insulation efficiency. Lower values indicate better insulation and reduced heat loss.

  • SHGC: Measures solar heat gain. Lower values help reduce overheating and cooling costs in warm climates.

Title 24 adjusts these values based on:

  • Orientation (north, south, east, west)

  • Climate zone requirements

For example:

  • In hot climates, south-facing windows require lower SHGC values to minimize heat gain.

  • In cold climates, north-facing windows require lower U-factors to prevent heat loss.

Air Leakage and Building Performance

Uncontrolled air leakage affects energy efficiency and increases heating and cooling costs. To prevent energy loss, Title 24 Non-Residential standards set strict air leakage limits based on:

  • Building size

  • Building shape hotel del coronado, san diego, california, flower wallpaper, flower background, lodging, rooms, hdr, nature, sky, clouds, architecture, landmark, beautiful flowers, flowers, plants, palms, san diego, san diego, san diego, san diego, san diego

  • Building volume

Sealing requirements for doors, windows, and vents help:

  • Optimize HVAC performance

  • Reduce unnecessary energy consumption

How to Achieve Title 24 Compliance for Non-Residential Buildings

Title 24 Calculations and Compliance Report

To demonstrate compliance, we generate a Title 24 Non-Residential compliance report using CEC-approved software tools. These tools analyze:

  • Building geometry

  • Insulation and fenestration properties

  • Air leakage rates

Our report includes:

  • CEC-NRCC-ENV-E Form – Contains all necessary information for building permit approval

Title 24 Documentation and On-Site Inspection

Building inspectors require the following Title 24 compliance documents on-site:

  • Certificates of Compliance (NRCC/LMCC) – Confirms that the design meets Title 24 energy efficiency standards.

  • Certificates of Installation (NRCI/LMCI) – Verifies that energy-efficient materials and systems have been correctly installed.

  • Certificates of Verification (NRCA/LMCV) – Confirms that performance testing has been conducted and that systems are functioning properly.

Failure to provide these forms can result in:

  • Project delays

  • Non-compliance penalties
