ANSI/ASHRAE/IES Standard 90.1-2019
ASHRAE 90.1-2019 is a residential and commercial building energy code that is designed to reduce energy consumption. The goal of this code is to reduce energy consumption by outlining design and construction requirements for lighting controls. The use of lighting controls such as occupancy status sensors, daylighting controls, and scheduled/manual inputs are required to achieve ASHRAE 90.1-2019 compliance.

IECC 2018
The International Energy Conservation Code (IECC) 2018 is a residential and commercial building energy code that has been adopted by many states and municipalities. The goal of this code is to reduce energy consumption by outlining design and construction requirements for lighting controls. The use of lighting controls such as occupancy status sensors, daylighting controls, and scheduled/manual inputs are required to achieve IECC 2018 compliance.

California Energy Commission Title 24-2019 Part 6
Title 24-2019 is a residential and commercial building energy code that is designed to reduce energy consumption. The goal of this code is to reduce energy consumption by outlining design and construction requirements for lighting controls. The use of lighting controls such as occupancy status sensors, daylighting controls, demand response, and scheduled/manual inputs are required to achieve CEC Title 24 compliance.
ON/OFF CONTROL and OCCUPANCY SENSING
| Code Provision | Control Requirement | Code Description | Intermatic Product Solutions |
|---|---|---|---|
| 130.1(a) | Local Manual Switch | Luminaires must be controlled with accessible manual on/off local control. Each space and area enclosed by ceiling-height partitions must be independently controlled. NOTE: General lighting must be separately controlled from all other lighting systems in an area. Floor and wall display, window display, case display, track, ornamental, and special effects lighting should be separately controlled and placed on circuits that are 20 amps or less. |
ARISTA System Components
|
| 130.1(b) | Multi-Level Control | Lighting of any enclosed area 100 square feet or larger with more than one luminaire and a load greater than 0.5 W per square foot should provide multi-level lighting control that meets uniformity requirements in accordance with Title 24 Table 130.1-A. Lighting control cannot override local on/off or any other control requirements. | |
| 130.1(c) | Shut-Off | Lighting must be controlled by either 1) an occupant sensing control, 2) automatic time-switch control with 2-hour maximum override and holiday scheduling, or 3) other control capable of automatically shutting off lighting. Indoor shut-off zones must be separated using ceiling high partitions and can be no larger than one floor with a maximum of 5,000 square feet. NOTE: Countdown timer switches shall not be used to comply with the automatic shut-off control requirements in Section 130.1(c)1, except in single-stall bathrooms and closets that are less than 70 sq. ft. where the lights must shut off within ten minutes, or in a server aisle/room where the lights must shut off within 30 minutes. | |
| 130.1(c)5/6/7 | Sensor Shut-Off | Occupancy Sensing Controls are required to shut off all lighting. Full or partial OFF to at least 50% via occupant sensing controls is required. |
LIGHT LEVEL CONTROL
| Code Provision | Control Requirement | Code Description | Intermatic Product Solutions |
|---|---|---|---|
| 130.1(d) | Automatic Daylighting Controls | Automatic daylighting controls should be installed and configured in all daylit zones as defined by 130.1(d). Lighting controls should have multilevel functionality to at least the number of control steps defined in Title 24 Table 130.1-A. NOTE: The photosensor must be readily accessible to authorized personnel for calibration adjustments. To prevent unauthorized access, the photosensor may be mounted inside a case that is secured with a locking mechanism. |
ARISTA System Components
ARISTA is currently recommended for buildings up to 10,000 sq. ft. in California, until we release our Demand Response solution. |
| 130.1(e) | Demand Response Ready | Buildings greater than 10,000 square feet with a lighting power density ≥0.5 W per square foot are required to receive a standards-based messaging protocol, which automatically reduces lighting power by at least 15% and remains consistent with uniform illumination requirements defined in Title 24 Table 130.1-A. |
PLUG LOAD CONTROL

|---|---|---|---|
| 130.5(d) | Controlled Receptacles | Based on the application, some of the receptacles in a commercial space are required to automatically turn OFF based on occupancy, either at the circuit level or at the receptacle level. When an automatic timer switch control is installed, it shall incorporate an override control that allows the controlled receptacle to remain ON for no more than 2 hours. Each uncontrolled receptacle must have at least one controlled receptacle within 6 feet. |
