Lighting Control: What’s in the New Title 24?

10/26/2022 by Craig DiLouie Leave a Comment

On January 1, 2023, the 2022 version of California’s energy code—Title 24, Part 6 of the Building Standards Code—takes effect, superseding the previous 2019 version. In terms of lighting controls, the numerous changes include various clarifications and tuning along with two major provisions requiring occupant-sensing in offices larger than 250 sq.ft. and demand-responsive lighting controls. Designers and specifiers need to understand these changes before they begin working on code-covered new construction and alteration projects that will go out for permit in California in 2023.

Automatic Control for Plug Loads

12/20/2017 by Craig DiLouie 2 Comments

Controlling plug loads is a natural fit for the lighting controls industry, as the same devices and strategies are used for automatic shutoff of plug loads such as task lighting as for general lighting. This feature article by LCA Education Director Craig DiLouie, LC, CLCP looks at energy code requirements, compliance options, and control types.

All About Occupancy and Vacancy Sensors

08/21/2017 by Craig DiLouie 8 Comments

Occupancy and vacancy sensors are devices that detect when a space is unoccupied and accordingly automatically turn OFF (or dim) the lights, thereby saving energy. The device may also turn the lights ON automatically upon detecting the presence of people, providing convenience and a potential security aid. According to the Lawrence Berkeley National Laboratory, occupancy-based […]

Occupancy Detection Using Light

03/29/2017 by Lighting Controls Association Leave a Comment

A team of faculty and graduate students from the Rensselaer Polytechnic Institute Center for Lighting Enabled Systems & Applications (LESA) and Boston University was awarded a U.S. patent titled “Sensory Lighting System and Method for Characterizing an Illumination Space.” The patent describes how the LED lighting system in a space can detect occupants’ presence, location, […]

Higher Occupancy Sensor Resolution Promises Greater Savings

07/22/2015 by Craig DiLouie 1 Comment

Occupancy sensors are a proven strategy to reduce lighting energy consumption. As such, they are mandated by commercial building energy codes. Current codes require a maximum 30-minute time delay. Time delay is a field-adjustable setting that determines the amount of time between last detected occupancy and the lights switching or dimming. Newer codes may reduce […]

Exterior Lighting Control Strategies

12/16/2013 by Craig DiLouie 1 Comment

The latest generation of energy codes and standards require that building exterior lighting be turned OFF and/or reduced when not in use, producing significant energy cost savings. This includes outdoor area/parking lot, bollard, entrance/exit canopy and wallpack lighting. The following decisions will ensure that energy consumption is minimized by turning lighting OFF or turning it […]
