2016 Non-Residential Title 24 Energy Code Updates

(Following is a partial list of the most significant 2016 changes to the California Title 24 Non-Residential Energy Standards.)




  • Revisions to the mandatory requirements for metal framed and demising walls (§120.7(b)).
  • Changes to the prescriptive envelope requirements (§140.3(a)).
  • Revisions to the roof/ceiling insulation tradeoff for aged solar reflectance (TABLE 140.3 of the Energy Standards).
  • Significant changes to the total skylight area requirement (§140.3(c)4).
  • Revisions to the requirements for all fenestration alterations (§141.0(b)2A).



  • Clarification and simplification of existing language; removing exceptions no longer relevant (§130.0 through §130.5 and §140.6 through §140.8).

  • Removal/addition of power adjustment factors (PAFs) (§140.6(a)2).
  • Significant reductions in outdoor lighting power allowances (TABLE 140.7-A).

  • New definitions of electrical metering, service equipment, plug load, and low voltage dry-type distribution transformer are added to §100.1.
  • Revisions and clarifications of service electrical metering §130.5(a), separation of electrical circuits in §130.5(b), voltage drop in §130.5(c), and circuit controls in §130.5(d).
