Making the most of lighting retrofits
There are different types of lighting retrofit projects: fixture replacement, relocation, repair, ballast retrofit, clean and relamp only, and various other fixture-related tasks; some projects may not even involve working with existing lumminaires. As green building takes an even stronger hold of our industry, the focus of most projects will likely be adding to or enhancing the lighting control systems. So along with swapping out ballasts, replacing fixtures and reconfiguring overhead circuitry, there may be many new switches, sensing devices, signal cabling and control panels with which to deal.
The success or failure of your estimate will depend strongly on how much information you have about the existing fixtures, circuitry and your knowledge of the new control systems. Perhaps most importantly, it will depend on how you labor it all.
Know the complete scope!
This is so critical. You must read every sheet note thoroughly and study the entire specification manual, not just the lighting spec. Engineers love to hide little notes, such as general conditions and wiring devices, deep in other specification sections. And don’t forget to study the Division 01 Scope of Work documents or similar directives, which usually are issued to the general contractors.
Thoroughly study the architectural drawings to learn and/or verify what is happening with the ceilings. If the entire ceiling in an area is getting replaced, it is likely all the fixtures in that area will need to be taken down. However, if the ceiling is a T-bar type, the fixtures might be able to stay in place. Details such as this can have a major effect on your total estimated labor.
The same goes for researching and knowing which walls are getting removed or resurfaced, as there may be lighting fixtures, exit signs and related control devices that need to be removed and replaced. Sometimes, these fixtures and devices are not shown on the electrical drawings. What will you carry if they are not shown?
‘Intercept, connect to existing systems’
This is one of the most vague, nondescript and scary sheet notes. Engineers often use this sheet note because they don’t have a clue as to how this work should be done or if it can be done at all. The bigger problem is neither do you.
Unless you are able to spend several hours or days at the job site prior to the bid—combing through the ceiling, opening junction boxes, testing and tracing circuits, and following conduits and cable routings—you will only be able to make a blind guess at what to carry in your bid.
Be very careful with notes like this. Visualize what might be needed if the installation were new; carry some new conduit, wiring and a J-box or two. Add a little extra labor for the time it takes the electrician to work with existing systems.
Demo doesn’t mean throw it away
Be careful with demolition notes. These, too, are often vague and nondescript and involve multiple stages of work. Quantify each part of the directed scope.
For example, a common fixture demo note found may read: “Remove existing fixture and retrofit with new dimming ballast, clean and relamp. Reinstall after new ceiling is installed.”
This note lists at least four separate tasks, each of which will occur at different stages of the project. What the note doesn’t list is how the replaced fixture will get connected. Does it get a new flex whip? Do you need new circuitry? What about ceiling wires? Supports? There could be a lot of other work required.
What about the “remove” part? If the fixtures are getting “replaced” at a later stage, then they will need to be stored in a safe place. Handling, protecting and storing these fixtures all requires careful labor, so you shouldn’t simply apply five minutes per fixture. Again, check the specifications. “Protect” could require bubble-wrap, palletizing or even special boxing. Not only would this add to the labor, but it could easily add $5 to $10 per fixture.
With multiple stage instructions like this, it is easy to omit material costs and/or labor. Your estimate could be off by $25 and 25 minutes per fixture location. This could be devastating, especially if there are several hundred fixtures.
Don’t forget the labor factor
Lighting retrofits can be labor-heavy jobs, and you don’t want to be too, well, light. It is common for some fixtures to remain in place during the retrofit process. This might seem simpler and faster than having to demo, store and reinstall them, but don’t get too relaxed. The work is still going to be done on a ladder, scaffolding or a lift. This can add a labor factor to a ballast installation. Also, ceiling heights can vary, and the labor factor increases dramatically when you are retrofitting high-bay fixtures in high ceiling areas, such as warehouses.
Estimating lighting retrofit projects can be very difficult to estimate and even more difficult to build. If you are not careful and bid too aggressively, you may find yourself and your profit lost in the dark.

Nice N Easy Convenience Store Features LED Lighting
Nice N Easy Grocery Shoppes' latest convenience store, which opened in Clay, N.Y., in September 2009, is one lean, green retail machine -- it's the chain's most environmentally friendly store to date, with a new design.
The 5,000-square-foot store features many firsts for the chain -- one of which is its exposed ceiling that is painted an earthy orange. Another is the dual rows of fuel dispensers. And one other first is the size of its foodservice section, which takes up an impressive 25-plus percent of the store, the most of any store to date.
There, customers can get a wide variety of fountain and frozen drinks, coffee and specialty brews. The chain's made-to-order offering of subs, wraps, salads and sandwiches is available, as well as its pizza and bakery selections.
An open floorplan provides clear views to the walk-in beer cave, the LED-lit colors and 20-foot open case of beverages. There is also a dining area for customers and displays of fresh fruit and produce by the point-of-sale. The chain's in-store TV network plays local news and entertainment.
But what is most impressive is the store's state-of-the-art green technology. The store's lighting -- both inside and out -- is LED-based. In the non-retail areas, such as behind the coolers and in storage areas, lights are set to motion detectors.
"Some of the lighting is keyed to motion detectors. If you walk into the walk-in cooler, the only light to come on is the one directly over you. As you go deeper in, others will come on, and when you walk away they go out," explained Senior Executive Vice President Fran Duskiewicz. The store also utilizes something he calls "daylight harvesting," where a sensor will detect the amount of light coming in through a window, and will shut off nearby lighting if it is bright enough, and turn the light on as it gets darker.
It is difficult for the chain to determine the realized cost savings of the green technologies at its stores, because they have only been added to new-build locations, which would have to be compared with a similar existing store without the systems, said Duskiewicz.
"We can look at [new green stores and existing stores] side by side and compare them, and we've proven that it saves us money," he said. "Of course, there are extra construction costs, so you have to work through the return-on-investment first, but if you are doing this because it’s the right or the smart thing to do, then that is why you do it."

Star Market Grocery LED Retrofit Featured In VSMD Magazine
SuperValu Inc. (Eden Prairie, Minn.), the supermarket operator that has been out front in the green build movement, has added another color to its chest full of medals.The winner of gold and silver certification from LEED has built the first supermarket in the nation to receive a GreenChill platinum award from the Environmental Protection Agency for energy-saving refrigeration technology.
The new Star Market in Chestnut Hill, Mass., a flagship store for the company’s Shaw’s/Star Market division, is also the first supermarket in the nation to use all LEDs for its interior and exterior lighting.
“We intended this to be New England’s new standard for sustainable supermarkets,” says Holly Angell, SuperValu’s director of technology, energy and environmental."
The environmentally friendly touches fill this store, a 53,514-square-foot, two-level space that is a grounds-up replacement of a smaller, 50-year-old market. For example, the LED lighting will allow for an anticipated reduction of at least 50 percent in energy consumption. And these LED fixtures are expected to be maintenance-free for a minimum of five years. “The light output and quality are also maintained throughout the fixture life,” says Angell, “which is an additional benefit that’s often overlooked.”
New technology also allowed the retailer to dim these lights an additional 25 to 30 percent. And, in addition to saving energy, “LED lights provide a calming sensation with no flickering, hum or eye-straining ultraviolet light,” says creative design manager Harry Steen.
The award-winning green refrigeration technology allowed the refrigerant charge to be reduced by more than 90 percent, using just 275 pounds of refrigerant (versus the typical 3000-4000 pounds). Also, this is just the second store in the nation to use an on site 400kw combined heat and power fuel cell for 90 percent of the store’s energy. The fuel cell is virtually pollution-free and independent of the local power grid.

GlaxoSmithKline Office Retrofit with LED Lighting
The Mississauga office of GlaxoSmithKline Inc. (GSK), one of the world's leading research-based pharmaceutical, vaccine and healthcare companies, recently retrofitted their office with LED Lighting. LED lights use significantly less energy than incandescent, halogen or fluorescent tube lighting. They also provide increased brightness and require less maintenance. The average LED lighting fixture will pay for itself within 2 years of being installed.
Company Will Save $46,000 per Year
"Our previous light fixtures used 26 watts per hour. The LEDs use 9 watts," said Terrence DeWolfe of GSK. "That's a savings of 18 watts per hour, over ten hours a day, five days a week. Financially, that means $46,000 saved each year."
LED light are also much cooler than incandescents or CFLs, which helps to maintain a comfortable room temperature. "Not only do you save on electricity," DeWolfe added, "you save on cooling costs as well. These LEDs also have a much longer life expectancy than our old units, so we'll reduce labour and change out costs. It's good for business and good for the environment."
"We benefit from reduced consumption, with no change in lighting quality."
Technological developments have made LEDs available for a wide variety of applications, and they've become increasingly popular as more and more organizations recognize their economic and ecological benefits. "We're very pleased with our investment,"concluded DeWolfe. "We benefit from reduced consumption, with no change in lighting quality. LEDs are a great way to integrate good financial sense with good corporate citizenship."
Redbird LED based in Atlanta, GA has recently announced a new LED Tube Light lineup with numerous commercial applications. LED Tube lights now provide a better quality light with substantial energy and maintenance cost savings. For more info0rmation please visit their website- commercial led retrofits
