The study revealed that only 25 percent of the sidelighting photocontrol systems in the studied buildings were functioning well, whereas almost 100 percent of the toplighting photocontrol systems were found to be functioning well in the previous study. What went wrong?
Bi-level Switching Study Demonstrates Energy Savings
In this special report by the Lighting Controls Association, we will describe bi-level switching code requirements, its role in the Commercial Buildings Deduction, methods and equipment, and the results of a study of typical energy savings achievable with bi-level switching in popular applications.
DALI and the Promise of Digital Dimming
Dimming of fluorescent lighting offers significant benefits in terms of supporting visual needs with good lighting, giving users control of their own lighting, and energy savings. The advent of digital dimming offers a new option with clear advantages over traditional analog dimming. Digital dimming can be used almost anywhere that analog dimming can be used, for the same purposes: visual needs, personal control, daylight harvesting, scheduling and other control strategies. If fluorescent dimming is desirable for a given application, digital dimming can offer distinct advantages related to intelligence, flexibility and two-way communication.
Lighting Controls Association Welcomes Delta Controls to Membership
The Lighting Controls Association is pleased to announce that Delta Controls has been admitted to the Association’s membership, joining the industry’s other leading manufacturers of controls and controllable ballasts. For more than 20 years, Delta Controls has offered building control solutions to commercial, institutional and government buildings. Delta created the first fully integrated native BACnet building solution encompassing lighting, HVAC and access products.
Occupancy Sensors A-Z
While today’s occupancy sensors offer robust features, proven utility and reliability, they remain application-sensitive devices, which requires a properly educated designer and installer for the controls to be effective. The right occupancy sensor must be selected, it must be properly located and installed, and it must be field-calibrated.
In this article, we will examine the seven steps of the effective application of occupancy sensors.
Lighting Controls Association Adds “EE201: Daylight Harvesting Control” to Its Popular Education Express Program
The Lighting Controls Association (LCA) has announced the availability of EE201: Daylight Harvesting Control, a new course added to its popular Education Express program. Residing at the Association’s website www.aboutlightingcontrols.org, Education Express provides in-depth education about lighting controls and controllable ballast technology, application, system design and commissioning.
NEMA Launches New Website to Support Energy-Efficient Lighting Tax Deduction
NEMA’s Lighting Systems Division has launched a new website for owners, specifiers, installers, and sellers of lighting systems. The new website, lightingtaxdeduction.org, provides comprehensive education and implementation information about lighting upgrades covered by the commercial buildings tax deduction provision of the Energy Policy Act of 2005 (EPAct).
Why Do Daylight Harvesting Projects Succeed or Fail?
The Weidt Group conducted a study of daylight harvesting projects to find out if daylight harvesting projects are living up to their expectations. The team—consisting of Eijadi, Prasad Vaidya, Tom McDougall, Jason Steinbock and Jim Douglas—reviewed dozens of completed projects, most of which were sidelit using windows, and separated the success stories—some of them operating for 25 years—from projects they considered to be failures.
Leviton to Celebrate Centennial Anniversary
