What’s effective for non-residential mandates on January 1, 2020 in Title 24 of California’s energy code includes more stringent controls on existing building lighting alterations, consolidation of demand responsive controls and demand management requirements into a single new section and a requirement that all restrooms install occupancy sensor controls.
Non-Residential Lighting Regulation
The latest California Non-Residential lighting regulation updates occurred in 2016. The updates to Title 24 included changes to required lighting controls. In a nutshell, areas that require multi-level lighting controls are now required to have either a vacancy sensor or a partial-ON occupancy sensor—this includes classrooms, offices <250 square feet, Multi-purpose rooms <1,000 square feet, and conference rooms.
Occupancy Sensors automatically turn lights ON when motion is detected and automatically turn lights OFF when the space is vacant and motion is not detected for 15 minutes (timer selections generally vary from 15 min., 30 min. or 45 mins).
