Lighting controls: compliance plus savings.
Industrial lighting controls range from simple motion sensors to networked systems with dashboards. Title 24 compliance is required; smart controls add real savings.

Lighting controls scope ranges from basic (occupancy sensors per fixture, scheduling) to advanced (networked DALI or 0-10V systems, dashboards, integration with building management). Marin commercial controls $1,500-$30,000+ depending on scope and integration complexity. Title 24 compliance is baseline for new construction and major retrofits; smart controls deliver 30-50% additional savings beyond LED.
01Title 24 lighting control requirements.
California Title 24 prescribes specific lighting control requirements for commercial buildings. Required in nearly all spaces: occupancy/vacancy sensing (lights off when space unoccupied), multilevel switching or dimming (allowing lighting levels below full output), automatic shutoff (lights off when building closed). Required in many spaces: daylight harvesting (dimming or shutoff in spaces with natural light), demand response capability (utility can signal load reduction).
Specific applications have additional requirements. Open offices: multilevel switching with at least one mid-level option, occupancy controls. Warehouses: similar with aisle-specific controls. Manufacturing: process areas have specific exemptions but most must include controls. We design to Title 24 from project start; corrections after install are expensive. Title 24 compliance is verified at AHJ inspection and final occupancy permit.
02Control system types.
Standalone fixture controls
Integrated sensor in each fixture (motion, daylight). No external network. Lowest cost. Limited monitoring and reporting. Adequate for simpler applications.
Networked 0-10V or DALI
Centralized control system networking all fixtures. Programming via central interface, scheduling, scene control, monitoring. Mid-cost. Common for medium-complex commercial.
Advanced networked (PoE, wireless)
PoE-powered or wireless-networked fixtures with cloud monitoring, granular dashboards, integration with building management. Higher cost. Used in larger or feature-heavy installations.
03Marin commercial deployments.
Marin warehouse and industrial applications most commonly use networked 0-10V dimming with integrated occupancy sensing — sweet spot of cost, capability, and complexity. Fixtures with built-in motion sensors connect to a small panel controller that handles zone-level scheduling and aggregates sensor data. Typical 50-100 fixture warehouse: $3,000-$8,000 for controls scope above basic fixture wiring.
Office and mixed-use commercial often use DALI or wireless networked systems with more sophisticated programming and dashboard. Larger installations (200+ fixtures, multi-floor) benefit from advanced systems. We design system selection during project planning based on size, complexity, and feature requirements. Most projects benefit from at least basic networked controls; very small or very simple projects can use standalone fixture controls cost-effectively.
Common questions.
How are sensors calibrated?
Motion sensors have adjustable timeout (time from last motion to shutoff) and sensitivity. Daylight sensors have adjustable setpoint (footcandles triggering dimming). Initial calibration at commissioning sets reasonable defaults; adjustment during first month of operation tunes to actual use patterns. Networked systems allow remote calibration; standalone require on-site adjustment per fixture or zone.
What if my warehouse has dark periods that need lighting on?
Override capability is standard. Manual override switches in each zone or area allow occupants to keep lights on when needed (security walks, night shifts, special operations). Override duration is configurable — typically 2 hours before automatic return to sensor control. Some systems allow scheduled overrides for known events. We discuss override needs during design phase.
Can controls integrate with my building management system?
Often yes. Modern networked lighting controls have BACnet, Modbus, or API integration with major building management systems (Honeywell, Johnson Controls, Schneider). Integration scope depends on BMS make and version. Cost varies; sometimes simple integration is included in controls scope, complex integration requires additional engineering. We discuss with BMS contractor during planning.
What about emergency lighting?
Emergency lighting is separately regulated and uses different circuits with backup power source (battery, generator, or central inverter). Standard occupancy sensors don't control emergency lighting — emergency fixtures stay on during emergency conditions regardless of sensor state. Modern integrated systems sometimes monitor emergency lighting status alongside normal lighting; useful for compliance documentation and troubleshooting. We address emergency lighting separately from normal lighting in scope.
How do you handle pricing — flat fee or hourly?
Both, depending on scope. Routine service calls and predictable scope (panel replacement, EV charger install, transfer switch install, fixture replacement) are flat-fee quoted up front. Diagnostic visits and emergency scope are hourly because we don't know what we'll find. Either way, you get a written quote before work starts on anything significant, and we don't proceed beyond the quote without your sign-off.
How quickly can you schedule?
Depends on scope and season. Emergency dispatch: same-day across Marin County (1-3 hours business hours, 1-4 hours after-hours). Same-day standard service: 3-6 hours from call when capacity allows; otherwise next business day. Scheduled service work: 1-3 weeks typical. Larger projects requiring permits and PG&E coordination: 4-12 weeks depending on scope. We're upfront about timeline at the quote stage.
What warranty do you offer on work?
Our standard residential warranty: 2 years on labor, manufacturer warranty on parts (varies by product — typically 1-10 years). Major installs (panels, generators, EV chargers) often have longer manufacturer warranties (5-10 years). If there's an issue with our work in the warranty period, we come back and fix it at no cost. We also stand behind work past warranty — repeat customers and referrals matter more than a transactional fix.
Are you licensed and insured?
