Department of Energy Names ASHRAE 90.1-2004 as New National Energy Standard

03/31/2009 by Craig DiLouie Leave a Comment

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 […]

What’s New for Lighting in the IECC 2009 Model Energy Code

02/09/2009 by Craig DiLouie Leave a Comment

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

2007 Energy Law Eliminates Sale of Probe-Start Metal Halide Fixtures

12/12/2008 by Craig DiLouie Leave a Comment

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.

Congress Extends Commercial Buildings Deduction to 2013

11/12/2008 by Craig DiLouie Leave a Comment

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.

Load Shedding Ballasts Enable Demand Response Retrofits

10/12/2008 by Craig DiLouie Leave a Comment

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 […]

Research Demonstrates Controls Can Help Reduce School Average Power Density to About Half of ASHRAE 2004/2007

04/12/2008 by Craig DiLouie Leave a Comment

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.

What’s New for Lighting in ASHRAE 90.1-2007

03/12/2008 by Craig DiLouie 1 Comment

In terms of lighting, ASHRAE 90.1-2007 clarifies the Standard’s intent and enacts several refinements but otherwise doesn’t revise the lighting power density (W/sq.ft.) limits from the 2004 version, which itself was 20-25 percent more stringent than the 1991/2001 versions.

New Energy Law to Phase Out Today’s Common Incandescent Lamps, Probe-Start Metal Halide Magnetic Ballasted Fixtures

01/12/2008 by Craig DiLouie Leave a Comment

The Energy Independence and Security Act of 2007 (HR6) does not include many provisions directly related to lighting. Two of its provisions, however, are nonetheless highly significant. One virtually eliminates the manufacture of today’s >150W to <500W probe-start metal halide magnetic ballasted fixtures starting in 2009 (replacement ballasts are not affected). Another virtually eliminates the manufacture of most common general-service incandescent lamps, putting billions of sockets up for grabs. The Act also has its eye on a possible LED general-service lamp in the future, establishing incentives to develop an LED product that can take on the 60W incandescent. The Act also distinguishes itself in two other ways. One is what it does not contain, such as encouragement of more-efficient residential energy codes and any tax provisions such as an anticipated extension of the Commercial Buildings Deduction to December 31, 2013. Another is its provisions that may indirectly affect lighting, such as its tough new energy reduction requirements for Federal buildings and the establishment and funding of a Director and Office of Commercial High-Performance Green Buildings, which will work with a private-public partnership to realize a goal of all newly constructed commercial buildings being “net zero energy” by 2030.

Study: Controls Combine to Deliver Large, Persistent Energy Savings and Improved Occupant Satisfaction in Open Office

12/13/2007 by Craig DiLouie Leave a Comment

What are the benefits of combining advanced lighting control strategies in the same space? Are the energy-saving benefits of lighting controls persistent over time? Can advanced lighting controls be successfully applied to open offices given concerns about jurisdiction conflicts, lighting uniformity, etc.? Can they enhance worker satisfaction? A new office lighting field study addresses these questions. Involving about 90 workers in a real-world open-office environment, the one-year study determined that occupancy sensing, daylight harvesting and individual occupant dimming control worked together in the building to produce average energy savings of 47% while correlating with higher occupant environmental and job satisfaction. The study demonstrates that sophisticated lighting control strategies can be combined successfully to generate persistent, large energy savings in open-plan offices while improving occupant satisfaction with their jobs and workspace.

Sidelighting Photocontrols Field Study: Lessons Learned

09/12/2007 by Craig DiLouie Leave a Comment

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?
