Building automation systems (BAS) provide automatic control of electrical loads, such as HVAC, lighting and electric motors, and functions not related to energy management, such as security and fire safety systems. Energy management systems (EMS) provide automatic control of electrical loads to manage energy consumption either as a stand-alone system or as part of a BAS. While EMS may be capable of provide automatic switching of large blocks of lighting loads, only a fraction of installed EMS actually control lighting, according to the U.S. Department of Energy (2003). EMS that control HVAC are installed in about 5.6% of commercial buildings representing 24% of commercial floorspace—most commonly >100,000 sq.ft. office and education buildings—while EMS that control lighting are installed in 1.3% of buildings covering 7.4% of floorspace.
The U.S. Department of Energy (DOE)’s Commercial Lighting Solutions (CLS) program, a component of Commercial Building Energy Alliances, seeks to stimulate adoption of advanced lighting technologies and design practices by making them available to the broader lighting specification community, not just the leaders in the field. The result is an extraordinary interactive web tool that enables any lighting decision-maker to save 30% more energy than the ASHRAE 90.1-2004 standard energy code without sacrificing lighting quality that users need from lighting systems.
Lutron Services Company, a division of Lutron Electronics Co., Inc., provides solutions to upgrade or fully replace an existing lighting control system, from start to finish.
Watt Stopper/Legrand has launched a versatile 0-10 volt wall box controller that can be used to dim or switch lighting loads or raise and lower shades. The DRLV1 controller is the first such device to include an input allowing automatic control by an occupancy sensor when used for lighting control. The device is RF-enabled and is also the first 0-10 volt wall box controller that can be incorporated into a wireless scene control system.
Panasonic Electric Works of America and PLC-Multipoint, Inc. have announced a contractual relationship whereby PLC-Multipoint will act as a United States distributor of Panasonic brand of lighting control equipment based on the unique Full – 2Way communication protocol. PLC-Multipoint will also use Panasonic brand components for their own product lines.
All energy codes require that general lighting be automatically turned OFF when it’s not used. Further, IECC says that if an occupancy sensor is used in an enclosed space such as a private office, light level reduction controls are not needed, suggesting an either/or choice. What if bilevel switching was combined with occupancy sensor functionality? Would this produce higher energy savings in a private office than bilevel switching or occupancy sensing alone. And: What combination of manual initiative and automation would produce the highest energy savings while also satisfying workers? The California Lighting Technology Center (CLTC) organized a study in eight private offices at the University of California – Davis in 2008 to attempt to generate useful data related to these questions.
ASHRAE/IES 90.1 Energy-Efficient Design of New Buildings Except Low-Rise Residential Buildings was first published in 1975 and updated in 1980, 1989, 1999, 2001, 2004 and 2007. After 2001, the intention is to update the Standard every three years. Applicability: Today, most states have adopted either 90.1 or the International Energy Conservation Code (IECC) as their […]
The path to energy-efficient lighting takes another step forward with the introduction of the Wireless Occupancy Sensor from Lutron Electronics Co., Inc.
Lightronics’ new SR Series features inexpensive wall stations at every entryway. The SR-516 features: In-Line DMX Scene Processor, Remote Wall Station Control and 16 Scenes w/ Fade Times to 99 Minutes.
A brand new flag is flying high over the Universal Lighting Technologies manufacturing plant in Matamoros, Mexico. The facility is officially green and clean. The federal government of Mexico certified the plant as a “Clean Industry” under the prestigious Industria Limpia program.
