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.
Watt Stopper/Legrand has developed a new occupancy sensor with a special coverage pattern tailored to meet the needs of retail applications with refrigerated cases. The FS-705 Wide-angle PIR Occupancy Sensor detects motion in aisleways in order to turn display lighting on when a customer approaches and off when it is not needed. The sensor may also be used to control general lighting and vending machines.
While planning the Palms of Perdido condominium project on beautiful Perdido Key, Florida, developers and resident owners Dick and Teresa Domurat spent several years researching amenities, including lighting controls. They selected Miro wireless RF controls and occupancy sensors from Watt Stopper/Legrand based on ease of installation, simplicity of system expansion and product performance and styling.
Watt Stopper/Legrand has introduced a self-calibrating daylighting controller that reduces time-consuming installation and setup. The LS-102 Daylighting Controller provides closed loop, single zone, on/off switching of most types of lighting in response to daylight contributions.
Watt Stopper/Legrand has developed the BZ-50 and BZ-150, two high output, universal voltage, plenum-rated, RoHS-compliant power packs that provide customers with greater design flexibility as well as increased energy savings potential. The power packs use zero crossing to switch line voltage loads and provide 24VDC to power occupancy sensors or other devices. The BZ-150 is the first power pack that can be field configured for manual-on operation to support either a manual-on or bi-level automatic-on control strategy.
Principals and associates at The Lighting Practice, a design firm based in Philadelphia, Pennsylvania, have long advocated sustainable design, and have recently had the opportunity to take their own advice. While planning a move that was completed in June 2007, they designed tenant improvements incorporating energy saving lighting controls that exceeded code requirements and let them demonstrate best practices to customers.
Associate Principal Julie Panassow and Lighting Designer Pomme Suchato were responsible for lighting the new space, and they selected a lighting control panel, occupancy sensors and daylighting controls from Watt Stopper/Legrand to achieve their goals. They succeeded in reducing the firm’s demand for energy, and set a green example for clients.
When interior designer Katy Mellon, Allied Member ASID, undertook designing the complete remodel of a 1968 tract home in San Diego, California, she embarked on an eye-opening learning experience. The prime goal was to create a safe, efficient, attractive and accessible home for her son, Nathaniel Ladendorf. Ladendorf is disabled from a spinal cord injury and needs wheelchair access to all areas of his residence. Mellon also had to meet California Title 24 requirements, but did not want to compromise her design scheme in order to do so.
Lighting controls, including Watt Stopper/Legrand’s Miro controls and residential occupancy and vacancy sensors, played an important role in the successful completion of the project. Ladendorf moved into his home in December 2007 and Mellon says, “Every time I see Nathaniel come into his house and touch just one switch to light up his safe haven, I experience great peace of mind.”
Watt Stopper/Legrand has released a new multi-location vacancy sensor and compatible remote control switch to help families save energy conveniently and cost effectively in rooms with more than one switch location. The RH-250 residential wall switch sensor is more versatile than any other product on the market, allowing customized control options including automatic-on operation from selected locations.
Watt Stopper/Legrand announces the launch of RoHS-compliant commercial occupancy sensors as part of the company’s ongoing commitment to the planet. Specifiers, building owners and contractors who select these lighting controls can be assured that they are helping reduce the amount of hazardous waste that will enter the environment, in addition to achieving energy savings.
Watt Stopper/Legrand’s Isolé plug load controller provides a convenient way for building managers to prevent wasted energy from a wide variety of electrical devices in private and modular offices. Isolé couples a personal occupancy sensor with a surge-protected power strip to turn off unneeded devices when a space is vacant while also protecting expensive equipment. It is the only occupancy-based plug load controller available.
