ASHRAE/IES 90.1 Energy-Efficient Design of New Buildings Except Low-Rise Residential Buildings was first published in 1975 and updated in 1980, 1989, 1999, 2001, 2004 and 2007. After 2001, the intention is to update the Standard every three years. Applicability: Today, most states have adopted either 90.1 or the International Energy Conservation Code (IECC) as their […]
IECC 2009 contains a number of changes impacting lighting for commercial buildings, including:
• Forced choice of compliance with entirety of IECC or 90.1
• Required circuiting for independent control of lighting in “daylight zones”
• Revision of additional retail display allowances
• Added exemptions to interior lighting wattage that must be counted for compliance
• Splitting the exterior power allowance using a system of outdoor lighting zones
• Clarifications and practical application language changes
The Energy Independence and Security Act of 2007 contains significant provisions affecting the sale of metal halide lighting fixtures. Starting in 2009, 150-500W metal halide lighting fixtures must contain ballasts that operate at a certain level of efficiency, virtually eliminating probe-start lamps and ballasts from new fixtures. This provision of the 2007 Energy Act essentially makes a Federal standard of efficiency requirements already enacted in California, New York, Arizona, Oregon, Rhode Island and Washington.
The Lighting Controls Association (LCA) has updated EE102: Switching Controls to include a new and improved section on load scheduling controls as part of its popular Education Express program.
The Energy Policy Act (EPAct) of 2005 created the Commercial Buildings Deduction (CBD), which established an accelerated tax deduction rewarding investment in energy-efficient interior lighting, HVAC/hot water systems and building envelope. Initially set to expire December 31, 2007 and then December 31, 2008, the CBD was recently extended by Congress to expire in five years: December 31, 2013.
Demand is the sum of all electric power required to run a building’s equipment currently in operation. As equipment is turned on and off, demand rises and falls. Peak demand is the highest level of demand recorded by a demand meter during a given time period. This is the most expensive power the utility has […]
The National Electrical Manufacturers Association (NEMA) launched the Premium Ballast program to identify the industry’s most efficient fluorescent fixed-output and dimmable electronic T8 ballasts, thereby providing a mechanism for market recognition and specification of these products.
The National Electrical Manufacturers Association (NEMA) has published LC 1-2007 Test Procedure for Compatibility of Hearing Aids and Ultrasonic Lighting Control Devices. This standard provides a basis to evaluate the possible interactions between ultrasonic lighting control devices and hearing aids utilizing a set of test procedures. This evaluation can be used as the basis for specifying performance criteria for both hearing aids and occupancy sensors to eliminate interference.
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.
The Lighting Controls Association (LCA) has announced the availability of EE204: Hi-Bay Lighting Upgrades, a new course added to its popular Education Express program. Residing at the Association’s website, Education Express provides in-depth education about lighting controls and controllable ballast technology, application, system design and commissioning, as well as meta-issues such as LEED, energy codes and other trends.
