Electrical Contractor Magazine recently published a major story on lighting controls featuring LCA members Leviton, Lutron, OSRAM SYLVANIA and WattStopper, in addition to comments from Craig DiLouie representing the Lighting Controls Association. The article, titled “Take Control,” outlines control strategies that building owners and managers can deploy now to reduce energy costs and increase flexibility in existing building lighting systems.
Emergency lighting can constitute as much as 20 percent of a commercial building’s lighting load, according to research conducted by WattStopper, which points out, in a whitepaper titled, “Emergency Lighting and Control,” that special control approaches can be used to reduce this load and generate significant energy savings while satisfying life/safety demands and code requirements.
While automatic shut-off provides increased savings for customers, research suggests implementing advanced strategies available with manual controls like switches can really turbocharge both energy savings and return on investment.
Control wiring provides a path for command and status communication between control devices in a lighting and control system and, in many cases, power to the devices as well. Wiring is interrelated with overall lighting control system considerations—such as selection of control system and components, layout and installation practices—and is therefore an important consideration when choosing a lighting control solution.
WattStopper has enhanced its extensive offering of energy-efficient lighting controls with a line of wallbox dimmers and fan speed controls to help building owners and facility managers capture energy savings when lighting is on. The new dimmers include a family of specification-grade Architectural Dimmers, intended primarily for commercial applications, and three families of designer dimmers for commercial, hospitality and residential applications.
WattStopper has developed PlugCalc as a key component in its Energy Calculator Tool Kit. The tool is available online at http://www.wattstopper.com/calculators/ or as a free downloadable iPad app. PlugCalc enables users to calculate energy savings opportunities as well as Return on Investment (ROI) by automatically controlling plugged in office equipment and other plug loads.
WattStopper has added network capability to its self-configuring Digital Lighting Management (DLM) lighting control product line, enabling remote management of lighting controls throughout a floor, a building or an entire campus. This major product line expansion also includes two new DLM digital photosensors for automatically switching or dimming up to three zones of lighting in daylit areas, new DLM lighting control panels, and powerful new dimming features for DLM wall switches.
Kaiser Permanente installed WattStopper lighting controls as part of a warehouse renovation designed to improve lighting and reduced energy consumption. The upgrade resulted in better task lighting throughout the facility and energy savings of over 40%, as detailed in the following case study.
WattStopper has announced four new multi-way wall switch occupancy sensors for code-compliant lighting control in commercial spaces with more than one entrance or switch location. The sensors provide convenient full-function multi-way control and install easily using traditional three- and four-way wiring. The product offering includes the industry’s first dual relay multi-way occupancy sensors, facilitating economical control of bi-level lighting or multiple loads.
