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.
Watt Stopper/Legrand has developed the LS-301 Dimming Photosensor, carefully combining features for optimal performance and ease of installation and use. At the heart of the device is the groundbreaking sliding setpoint control algorithm pioneered by Watt Stopper/Legrand. The LS-301 also employs a handheld setup remote to facilitate quick and convenient commissioning.
Watt Stopper/Legrand introduces the new fixture-mounted FD-301 dimming photosensor. Lighting fixture manufacturers can easily integrate the FD-301 during production so fixtures arrive at the jobsite with the control pre-wired, adding value and saving contractors’ time. Commissioning, too, is fast and simple. Once operational, the photosensor provides precise and reliable energy-saving control, dimming 0-10 VDC ballasts in response to available daylight. Integrating the device into the fixture also improves aesthetics, reducing the number of items on the ceiling.
NYSERDA sponsored a demonstration project featuring a new Integrated Classroom Lighting System (ICLS) created by Finelite, Inc., a fixture manufacturer, installed as a retrofit into 28 existing classrooms at seven schools and universities. The Lighting Research Center (LRC) assessed teacher and student satisfaction. The result is a design template demonstrated to satisfy audio-visual needs and improve teacher and student satisfaction while reducing lighting power density to an average 0.73W/sq.ft., nearly 50% less than ASHRAE 90.1-2004/2007. Although Finelite optimized the design into an engineered system integrating the company’s light fixtures with state-of-the-art lighting control strategies, the template, if properly designed, can be treated as open source with suitable products from a wide range of manufacturers.
