This is especially valuable when retroftting your pro shop — replacing those halogen spot - lights with LEDs will result in air condition- ing savings and overall summer comfort. A 60-watt halogen temp is clocked at about 200 F while its super-cool LED counterpart runs around 70 F. Additionally, LED bulbs have a much longer life expectancy than con - ventional bulbs. Grab the low-hanging fruit and start re - placing halogen, incandescent and even those compact fuorescents with LEDs and see your energy bill change its attitude. Check to see what the market offers with your fuorescent tube lights — T12s are outdated and were re - placed with T8s, which are now moving into even higher effciencies with LED retrofts. Fluorescents contain mercury and are con - sidered hazardous waste. Check with your local waste collection agencies or retailers for proper disposal. See for more information on cleanup and disposal. Once you make some signifcant changes, you are going to make a dent in an otherwise stagnant and uncontrolled fxed cost. That is something to get a little excited about. Pamela C. Smith, CGCS, is the director of agronomy for a large metropolitan city and a 23-year member of GCSAA. Pamela C. Smith, CGCS (environment) Face it: there is nothing exciting about utility bills. A facility's electrical expense hides deep in the white noise of the operation's fxed costs. Set aside money for a new piece of equipment and you are giddy. However, bud - geting and paying the electric bill is as blah as it gets. Energy use is a cost of doing business and unless you convert to an alternative source of energy, there doesn't seem to be a way to beat this bill. Or is there? Take on a lighting retroft and you will be impressed with the results. The basic ret - roft will swap out old incandescent or out- dated fuorescent with cooler energy-eff- cient light-emitting diode (LED) bulbs and higher effciency fuorescents. Here is how you do it. • Conduct an audit of your bulbs and fx - tures. Capture information such as brand, make, model, wattage, fxture and loca - tion. If you get overwhelmed, just stick with one location or even just one type of bulb. • Talk with a knowledgeable lighting supply company or two. Share the fndings of your audit and ask them to quote energy-saving alternatives to replace your existing bulbs. Many companies are willing to send a sales - person out to do the audit with you; take advantage of their expertise. • Calculate the cost of the retroft and the anticipated savings. Your local energy company may have a calculator (drop me a line if you can't fnd one and I will email you one). Make sure your retroft Disclaimer I know you can re-wire a blown satellite in the dark, surrounded by rabid coyotes, while you have the fu. BUT, give a second thought to doing your own building wiring. You can save a lot of money doing it yourself, but the risk may not be worth the reward. These are occupied buildings, and doing your own wiring carries a heavy burden. Check with your company to fnd out if you are allowed to do this work or if they, their insurer or local code requires a certifed electrician. Always follow lockout tag-out procedures.

Sometimes the upgrade is not worth the initial outlay because technology has not caught up to all types of bulbs. • Contact your electric company to learn about their rebate programs and become best friends with their representative who handles rebates. They can be a valuable technical source to help you get the most out of the rebate process for your project. • Get your management team and market - ing on board with your fndings and pro- posal. Let them know the effort it took to plan and implement these savings. If they aren't interested, then wait for the savings and make your own good press. • Bonus retroft: replacing wall switches with occupancy sensors can save a bunch of energy by keeping unoccupied spaces in the dark. Check with your rebate program to see if any or all of the occupancy sensor cost is covered. The table above shines some light on fxing that fxed cost by giving a few examples of how two easy retrofts could save a pile of money. The cost for the bulbs for each project was about $20-$25. This makes the return on investment anywhere from about one to two years. One extra beneft of converting to LED bulbs is that the LED bulbs run cooler than 038-039_April14_Envirn.indd 38 3/18/14 2:47 PM
