Building Energy Efficiency Standards - Title 24
The 2013 Building Energy Efficiency Standards (Energy Standards) introduce new requirements for nonresidential lighting wiring alterations (Section 141.0(b)2Iiv). The following is a summary of the new requirements.
Section 141.0(b)2 of the Energy Standards defines the requirements for the prescriptive approach to nonresidential alterations:
Prescriptive approach. The altered components of the envelope, or space conditioning, lighting and water heating systems, and any newly installed equipment serving the alteration, shall meet the applicable requirements of Sections 110.0 through 110.9, Sections 120.0 through 120.6, and Sections 120.8 through 130.5.
Typically, only the altered components must meet the requirements of Section 141.0. When Section 141.0 refers to mandatory requirements (Sections 110.0 through 110.9, 120.0 through 120.6, and 120.8 through 130.5), altered components only need to meet the requirements of the section(s) which applies.
