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.
The DesignLights Consortium’s (DLC) new report, Energy Savings from Networked Lighting Control (NLC) Systems, estimates average lighting energy savings of 47% resulting from installation of networked lighting control systems. The report indicates high potential energy savings for networked controls, supports layered control strategies as a means to maximize savings, and may be used to justify new and larger utility rebates. Craig DiLouie, LC, CLCP breaks it down in this month’s featured article.
Most commercial building energy codes require automatic lighting shutoff. This common-sense strategy also adds value to lighting upgrades in existing buildings. Remote switching is one method, with an option being switches residing in a metal cabinet-type enclosure called a panel. This panel can serve as the backbone for a complete energy code-compliant control system that responds to a wide range of control inputs for indoor and outdoor lighting control. It is typically sold as a new complete unit, though panelboard retrofit assemblies are available.
This article describes common panel-based lighting control systems.
In May 2016, the DesignLights Consortium® (DLC) released V.1.0 of its Networked Lighting Control Systems Specification, which formed the basis of a new Qualified Lighting Products List (QPL). The intent was to provide utilities and energy efficiency programs a resource to qualify networked lighting control systems so they could be covered in commercial sector lighting […]
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 […]
A good lighting design includes a good controls design. Lighting controls play a critical role in lighting systems, enabling users manually or automatically to: • turn the lights ON and OFF using a switch; and/or • adjust light output up and down using a dimmer. This basic functionality can be used to generate these benefits […]
When evaluating an existing lighting system, the owner can do nothing, something or everything. Doing nothing abandons operating cost savings. Doing something entails replacing lamps and installing some automatic controls. Doing everything involves installing a new lighting and control system. As many owners opt for the “something” option, demand for LED replacement lamps continues to […]
In 2015, the International Code Council published a new version of its International Energy Conservation Code (IECC). This model energy code provides states and jurisdictions code-ready language to adopt in whole or in part. It has been updated every three years since 2000. Today, a majority of states base their commercial building energy codes on […]
The Lighting Controls Association is proud to offer an advance look at a selection of new products that will be displayed by members at LIGHTFAIR International May 9-11, 2017 in Philadelphia. While some can be seen here, many more await at member booths, so be sure to visit! ACUITY BRANDS nLight ECLYPSE nLight ECLYPSE extends […]
By Craig DiLouie, LC, CLCP Many utilities offer incentive programs to customers to get them to use less energy. This is based on the premise that it is often cheaper to pay customers to use less energy than to build new generating capacity to satisfy future power demand. The simplest and most popular type of […]
