Solutions for Load SheddingWith energy alerts on the rise and demand charges increasing, load shedding has become an important lighting control strategy. Because many lighting loads are non-critical, they are prime candidates for load shedding along with other non-critical building loads.

Daylighting Controls
Load shedding with daylighting controls is a natural, automatic process. Because high energy demand often occurs at the same time daylighting potential is the greatest, the natural consequence of using daylighting controls will be to reduce lighting as the level of daylight increases and becomes adequate to replace artificial lighting sources.

With continuous dimming products, such as The Watt Stopper’’s LightSaver LCD control, users can define the minimum light level they want to maintain throughout the course of a day, and the dim- ming controls will adjust artificial lighting based on this setpoint and the available daylight contribu- tion. When daylight is adequate, lights will be dimmed and when daylight diminishes, artificial light levels are raised. The multi-zone option of the LCD enables the use of independent dimming controls in different areas of a building space, such as an open office area, where daylight levels may differ. One lighting zone, nearer to windows or skylights where daylight levels are higher, may dim artificial light- ing earlier in the day and to lower levels than in another lighting zone that is located further from the daylight source and receiving a smaller daylight contribution.

ON/OFF switching controls, such as The Watt Stopper’’s LightSaver LCO control, are also effective load shedding tools. Compatible with all lamp types, ON/OFF controls turn lights off when the daylight contribution reaches a user-defined level. Multi-zone controls enable bi-level, or stepped dimming, which can be particularly effective as a load shedding strategy. Most commonly, individual lamps with- in a multi-lamp fixture will be grouped into different zones; the inner lamps in three-lamp fixtures in one zone and the outer two lamps in a separate zone. The lighting in each zone is turned off once day- light levels reach a defined setpoint. Usually, the zone comprised of the inner lamps will be turned off first, reducing lighting by one-third. Later in the day, when the daylight contribution increases, the other lighting zone can be turned off. For more aggressive load shedding, the sequence can be reversed, to shed two-thirds of the lighting load earlier in the day.
The Watt Stopper Application Bulletin
Lighting Control Panels
Another effective tool for achieving load shedding is the use of lighting control panels. Panel prod- ucts perform load shedding by turning off non-critical loads during peak times.

For instance, users of The Watt StopperComplete Control panel products can employ a prepro- grammed control scenario to shed non-critical lighting loads. This could be half of the lighting in a "bi-level" controlled space. Under such a scenario, occupants are "locked out" from exercising local overrides via switches or telephone contact with the system. This control scenario can be pro- grammed to operate during daily intervals when peak loads are most likely to occur, or when a facility historically attains its highest demand. This strategy can also be invoked under energy shortage alerts.

Specialized Load Shedding Solutions
Additional automated load shedding solutions include teaming The Watt Stopper Automatic Relay Pack (ARP) with the Telephone Switch Module (TSM). Non-critical, sheddable loads are connected to one relay on the ARP-Net, while critical, non-sheddable loads are connected to the other relay. The TSM is installed on the ARP-Net network. During a power alert, a call into the TSM from the facility manager will turn off the relay with non-critical loads. The ARP’s lock-off capability ensures that once the signal from the TSM is received, lighting or other loads (i.e., HVAC, fans, etc.) immediately shut off, and that ordinary occupant overrides are not available. To restore the loads, the facility manager makes only a quick call back to the TSM and follows a sim-
ple push-button sequence.

LED Emergency Sconce

For the electrical engineering community here in Nashville and middle Tennessee, this is a great emergency LED sconce.  I have ordered a sample for TLC Engineers who asked to see the fixture and can bring it for a demonstration to anyone else who would like to see it...  thank you.

Cree Lighting CR24 Troffer

The R9 Value for the 3000K Cree CR24 is 80 which adds to the industry leading CRI of +90.  A link to the energy study is below.

Energy.Gov Study

Per the DOE website,

"A good CRI score does not guarantee good color quality

One problem with the CRI is that it can give fairly high scores to sources that render some saturated object colors very poorly. An example below shows a case of a red-green-blue (RGB) white LED simulation optimized for highest luminous efficacy of radiation (LER, lm/W) at CRI R

a=80. This light would qualify for Energy Star and achieve high luminous efficacy2, but the actual color rendering is very poor. With R9 = -114, skin tones under this light look pale and unhealthy. "

It’s Payback Time—New Cree LED Troffers Revolutionize Commercial Lighting

New Cree CR Series Delivers Shorter Payback, Better Light Quality and Efficacy than Fluorescents


DURHAM, N.C., April 26, 2011 — Antiquated, inferior commercial lighting gets a much-needed transformation with the revolutionary new series of LED troffers from Cree, Inc. (Nasdaq: CREE). The Cree CR family of architectural troffers, including the CR24™, CR14™ and CR22™, bring a superior combination of performance, aesthetics and affordability to a market traditionally lit by outdated, flickering fluorescent tubes.

The CR series is redefining commercial lighting by offering a no-compromise alternative when upgrading over fluorescent lighting. More affordable than comparable fluorescent options, CR series fixtures deliver higher-quality light, longer life and greater energy savings, with an estimated payback of less than a year in a typical office installation*.

“We chose the Cree CR troffers because the payback calculation was clear,” said Richard J. Michal PE, MBA, LEED-AP, facilities engineer planning design and construction, Butler University. “Seeing the CR troffers installed, they have an elegant aesthetic that produces an incredibly high-quality light. When you combine that with our predicted energy and maintenance savings, it was a no-brainer.”

“You never need to install fluorescent troffer lighting again,” said Chuck Swoboda, Cree chairman and CEO. “The traditional lighting experts keep telling us what LEDs can’t do, and we keep showing them that anything is possible. We think it is time to rid the world of the compromises inherent in choosing fluorescent lighting—the flickering, toxic mercury, poor color, ineffective dimming and disposal expense.”

“Our life cycle cost analysis using Cree LED lighting on our projects decreased the watts-per-square-foot by upwards of 60 percent,” said Nick Santore, PE, LEED-AP, Senior Electrical Engineer at O’Brien/Atkins Associates. “That decrease translated into measurable reductions in building HVAC equipment sizing requirements, delivering additional savings.”

According to Freedonia Group, the 2009 US indoor lighting fixture market is estimated at U.S. $6.4 billion. Lighting represents 27 percent of American commercial building energy consumption according to the U.S Department of Energy.

The Cree CR troffer family is powered by Cree TrueWhite® Technology to deliver an unprecedented combination of 90 CRI and up to 110 lumens per watt, far outperforming any other current lighting options.

An innovative thermal management system enables the LEDs to consistently run cooler, providing significant boosts to lifetime, efficacy and color consistency. All fixtures feature step or 0-10V dimming, are designed to last at least 50,000 hours and feature a five-year warranty.

The CR troffer family includes three models and multiple performance options: 1ft x 4 ft, 2ft x 4ft and 2ft x 2ft. For technical specifications, please visit crseries.CreeLEDlighting.com.

The Cree CR series is made in the United States, sold through Cree LED Lighting sales channels and is currently shipping in volume. For additional information about the Cree CR series of troffers, please visit crseries.CreeLEDlighting.com. The CR troffers will also be demonstrated at Cree’s booth #1925 at Lightfair International in Philadelphia, May 17-19.

*Payback calculations compare the Cree CR24 LED troffer with an architectural 2-tube T8 fluorescent fixture of comparable light output and features. The calculations also assume a typical office space of 200 units, 12-hour per day usage, $.10 kWh energy costs, lighting-related HVAC impact, and relamp maintenance. This results in a payback of less than one year when upgrading to more efficient CR series lighting from Cree.

Lighting Case Study, Mayo Clinic

When the Mayo Clinic broke ground on the $441 million Gonda Building, design manager Stan Larson said every purchase was carefully reviewed to ensure it would deliver long-term value.  “With the pressure of construction costs, we needed to deliver good quality within budget,” he said. Because Larson had successfully used a variety of Williams Downlighting products in past Mayo remodeling projects, he knew the company could meet the high standards required in a new world-class medical complex. “With some of our key lighting applications, we chose Williams Downlighting because they consistently deliver high performance at a competitive price.”

While Williams Downlighting was widely used in conference rooms, offices and hallways, a critical application was illuminating employee cafeteria and break room areas. As part of the open foyer design, the project called for colored-glass downlights in these locations that would be visible from the building’s main atrium. Though Williams Downlighting offered four standard colored-glass options for its recessed fluorescent fixtures, the company successfully delivered a broader palette of custom colors required by the Gonda project.  “This application had some really precise needs,” said Rob Chasse of JTH Lighting in Eagan, MN, who partnered with Larson on the project. “Williams Downlighting collaborated with its glass suppliers to make sure the final product was what the architect and lighting designers wanted.”

Mayo’s attention to detail has paid handsome dividends. The 20-story Gonda Building has received several architectural awards – including honors from the International Interior Design Association for excellence in interior lighting.  “The workmanship on the Williams Downlighting fixtures always seems to be higher than some of the other manufacturers that just stamp them out,” Larson said. “When I first saw their factory, I was impressed with their design ideas, manufacturing processes, and work ethic. Time and time again, that shows in the results we get in working with them.”

Wattstopper Revit (BIM) Files

WattStopper's new BIM Objects help streamline building design and construction

WattStopper introduces new BIM (Business Information Modeling) objects for its innovative lighting control products. BIM is a powerful tool that uses three-dimensional, real-time, dynamic building modeling software to increase productivity in building design and construction. BIM is at the heart of integrated project delivery (IPD), intended to bring the full range of stakeholders (e.g., architects, engineers, contractors, building product manufacturers, and owners) together prior to construction, allowing broad collaboration at an early stage as well as a high level of shared expertise. By providing data visually, it makes complex structures and data easily accessible to wide range of audiences.

While BIM has great value in new construction, it is equally useful in post-construction activities. For instance, the dynamic, three-dimensional model offers a wealth of information for facility managers, including precise information about building systems. This can improve energy analysis capabilities, streamline new tenant buildouts, and simplify regular preventive maintenance tasks.

The new WattStopper BIM Objects (also known as Revit families) are available for a majority of Digital Lighting Management (DLM) products and popular wall switch occupancy sensor models.

The library of BIM Objects are available free of charge on our website at: http://www.wattstopper.com/products/bim-resources.html
