The Lighting Controls Association (LCA) is pleased to announce that EE300: Lighting Control of LEDs has been added to the Association’s popular online Education Express distance education courses.
The National Electrical Manufacturers Association (NEMA) has published LL 9-2009 Dimming of T8 Fluorescent Lighting Systems. This new standard is the first coordinated guidance from industry on the dimming of T8 fluorescent lighting systems; LL 9 covers ranges between 100% and approximately 35% output (60mA lamp current). The publication was a result of discussions between numerous manufacturers and end-users as well as years of data gathering, testing, and analysis.
The DHMI is a 7-inch diagonal, high resolution, wide-screen format, color LCD used for interfacing with the Delta Controls building Automation System. The Delta DHMI uses BACnet over Ethernet to communicate with controllers on a local area network. User created graphics allow the DHMI to be completely customized for a given application.
In July 2009, the Department of Energy issued new energy efficiency standards for commercial general-service fluorescent lamps and incandescent (and halogen) reflector lamps. The new rules take effect July 14, 2012 and will basically eliminate products with the lowest efficiency and lowest cost. In the case of fluorescent lamps, equivalent-performance products are readily available, such as T8 lamps, and the market is expected to shift to that and other technologies. In the case of incandescent reflector lamps, only a few equivalent-performance products are readily available that comply, such as infrared-coated halogen lamps, and manufacturers are expected to develop new substitutes.
In a solution made for these challenging economic times, Encelium Technologies has announced that building owners and management can expect lower operating costs and a better return on investment through technology that enables the integration of the company’s Energy Control System (ECS) with Tridium’s Niagara AX building automation software platform. The dramatically improved integration of HVAC and other embedded devices with lighting is made possible by the Niagara AX Driver, according to Tony Marano, President and CEO of Encelium.
While general-service incandescent lamps have received the most attention in media coverage of the Energy Independence and Security Act (EISA) of 2007, with provisions beginning to take effect in 2012, many popular incandescent reflector lamps are being outlawed this month.
An additional 30-80 percent energy savings using occupancy sensors and 10-30 percent savings using daylighting controls can be achieved in a hi-bay fluorescent upgrade.
The Lighting Controls Association is pleased to announce that EE205: Personal Lighting Control has been added to the Association’s popular online Education Express distance education courses.
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.
