3 4 5 Lighting Lighting There are huge dollar savings hidden in your inefficient lighting. Energy-efficient equipment, effective controls and a well-planned design can result not only in energy savings, but increases in productivity, aesthetics and safety. Linear fluorescents Fluorescent tube lighting is a great way to light up large spaces, but not all fluorescents are created equal. Energy-efficient T8 lamps are up to 40% more efficient than old, inefficient T12 lamps. Bonus they also reduce eyestrain and render colors closer to natural light. High bay Lighting in warehouse, retail, manufacturing and industrial environments with ceiling heights greater than 20 feet is a particular challenge. Replacing outdated High Intensity Discharge (HID) fixtures with specially designed T8 or T5 fixtures can have a simple payback as little as two to four years. Induction Induction lighting is essentially a fluorescent light without electrodes or filaments, the parts that often cause fluorescent bulbs to burn out. With an average rated life of 100,000 hours (that s 11+ years, operating 24 hours per day) it s a great solution where accessibility to change the lamp is a challenge. Do you have T12 lighting? The simplest way to tell if you have T12 lighting in your facility is to look at the end of a fluorescent tube. If it s 1 1/2 inch in diameter, it is likely an inefficient T12 lamp. T12 1 1/2 T8 1 Lighting controls Even energy-efficient lighting saves money when turned off! Adding lighting controls increases the flexibility of your lighting plan. CFLs and LEDs Easy energy savings: count up the number of screw-in bulbs in your office, break room, restrooms and storage areas. Consider the savings for one bulb. Bulb type Annual operating cost Incandescent 60 watt bulb $17.86 CFL watt bulb $4.61 LED 6-8 watt bulb $2.08 Exit signs Exit signs: Each one uses relatively little electricity, but they are on all the time. And there are a lot of them in schools, factories and office buildings. In fact, the Environmental Protection Agency estimates that there are more than 100 million exit signs in the U.S., consuming billion kilowatt-hours (kwh) of electricity annually. LED traffic lights LED traffic lights use approximately 90% less energy than their incandescent counterparts, but that s just one advantage. Because they last so long, maintenance costs are reduced by 75%. This results in a simple payback as short as one to three years.

You simply pay the remaining balance. With the Small Business Energy Solutions program, you don t have to wait for a rebate check. Alliant Energy pays $0.14 per kwh saved directly to your selected lighting contractor. Here s how the program works: Select a specially trained lighting contractor and schedule a free, no-obligation lighting evaluation Schedule an evaluation at alliantenergy.com/simplesavings, or call After the evaluation the contractor develops a lighting project proposal, including costs and estimated savings, for your approval Upon project completion and verification, Alliant Energy pays contractor directly based on the kwh savings estimate up to 75% of the project cost You pay the remaining balance directly to the contractor Here s an example Replace 64 interior lights and 10 exterior lights with qualifying energy-efficient lighting. $3,500 - total project cost $2,625 - paid directly to contractor by Alliant Energy $875 - your cost, paid to contractor In addition, you would save $1,280 on annual energy bills, reaching payback on your investment in nine months.* *Assuming an energy savings of 16,100 kwh at $0.10 per kwh What customers think When we reviewed the energy savings and payback period, along with the fact that Alliant Energy paid a large portion right off the top, it was simple to say yes. Once the project was completed, our employees noticed an immediate improvement in the lighting which translates into improved productivity for our company.

5 8 9 Is it time to invest in new equipment to keep your business comfortable? With rebates for boilers, chillers, heat pumps, high-efficiency fan motors and thermostats there is an option for everyone. If you re not ready to replace your system, check out our new HVAC tune up rebate! System tuneup Keep your current HVAC equipment working at its best. With our new HVAC tuneup rebate, there is one more reason to get an annual check up to keep your system operating at its peak efficiency. Hotel key card system Heating and cooling The guestroom keycard energy management system can send guest rooms into an occupied or unoccupied mode and change the room settings to save energy. This technology provides guests with the control they want, while you save anytime the room is empty. Programmable thermostats Programmable thermostats can help you save up to 10% on heating and cooling when you adjust your thermostat for eight hours a day. Wi-Fi programmable thermostats will allow you even more control and potentially greater savings through your phone or other mobile device. Insulation and air sealing What s the number one way to save energy? It s insulation. Start with a free Business Energy Assessment to find out where you need insulation and have air leaks. Find details on page 3. Now our rebates include ductwork insulation, repair and sealing. Duct insulation You re paying to heat or cool the air that runs through the ductwork. Up to 30% of your energy can be lost if your ductwork is not insulated. Insulating ductwork is especially important if the ducts run through unconditioned spaces. The air running through the ducts can be warmed or cooled by the air temperature of the spaces the ducts run through. See all the rebates for insulation and air sealing on page 24. Duct repair and sealing Did you know up to 20% of your conditioned air could be leaking through your ducts? The result is higher energy bills and difficulty keeping your business comfortable. Stop duct leaks by repairing and sealing your ducts. Chiller pipe insulation Do you have piping in unconditioned spaces? Adding insulation on chiller pipes keeps the temperature of the water running through the pipes cooler improving the system s efficiency. Plus, it can control condensation on the pipes. Boiler vent damper Improve gas boiler efficiency with a boiler vent damper. It keeps cold air out and warm air in. The damper automatically allows the boiler to exhaust properly during operation, but prevents conditioned air from leaving your business. ECM furnace motor Electronically commutated motors (ECM) deliver multiple advantages. They run cooler and quieter and require less maintenance over a longer lifespan. All while using up to 50% less energy compared to induction motors. Heating and cooling rebate details available on page 22-23

6 10 11 Refrigeration Keeping it cool Walk-in strip curtains Rebates on refrigeration equipment just got easier! Previously, refrigeration rebates were available only through our Custom Rebate program, but starting in 2014 we re offering standard rebates on the most popular refrigeration equipment. Anti-sweat heater controls It s low-tech, easy to install, uses no energy to operate, and yet continuously saves you energy and money. What is it? It s the strip curtain on your walk-in refrigerator or freezer. By keeping dry, cold air in, and warm, moist air out, strip curtains lower electric bills and extend product life. In addition to saving energy, they help keep out dust, debris and bugs! Opening between the strip curtain and bottom of doorway must be no larger than one inch. Strips must have an overlay greater than one inch. Walk-in evaporator fan controllers Evaporator fans typically run at normal speed all the time, regardless of demand. An evaporator fan controller will automatically adjust fan speed, allowing for energy savings without an impact on the overall temperature of the cooler or freezer. Must reduce fan motor power by at least 75% when the compressor(s) cycle off. Refrigerated glass display cases use anti-sweat heaters to prevent moisture from forming on their glass and frames. Most typically operate non-stop 24 hours a day, 365 days a year, even when conditions don t require it. That can add up to as much as $200 per year per door in energy costs! Adding anti-sweat heater controls saves you energy and money, in the range of 70% to 90%. Controls must automatically reduce energy consumption of the anti-sweat heaters by at least 50%. Electronically commutated motors for refrigerated display cases and walk-ins Evaporator units, each with a small fan motor are integral components of walk-in refrigerators and freezers. Though each motor is small, when considered together and running continuously, the energy consumption is considerable. Installation of Electronically Commutated Motors (ECMs) can significantly reduce energy consumption and your energy bill. Must replace shaded-pole or permanent-split capacitor evaporator fan motors. Scroll compressors Scroll compressors not only use less energy, but have significantly fewer moving parts, resulting in superior performance, lower maintenance cost and greater reliability. Must replace reciprocating compressor. Display case night covers Leaving display coolers uncovered at night can waste a lot of energy. Using night covers on display coolers lowers heating and air conditioning costs overnight. Just keep things undercover while the store is closed. Must install a cover on an existing open refrigerated display case. For a list of all refrigeration rebates, see page 25.

7 12 13 Food service equipment Water heating Rebates on everything but the kitchen sink Alliant Energy s food service rebates aren t just for restaurants! Schools, grocery and convenience stores, community centers and churches any place there s food service preparation, there s potential for energy savings. Whether you re serving up school lunches or dinner at a five-star restaurant, it s an energy-intensive business. In fact, according to ENERGY STAR, the annual cost to operate a single gas or electric fryer is often more than the annual utility bill of an average home. Red-hot rebates Investing in new ENERGY STAR qualified cooking equipment could save you up to 30% on energy costs. Alliant Energy rebates range from $500 to $1,500 help you make the upgrade on cooking equipment including: Broilers Fryers Griddles Steam cookers Convection ovens Conveyor ovens Rotisserie ovens Rotating rack ovens Does your business use a lot of water? Water heating can be a large expense for many businesses. How large? It s typically the second biggest energy user, right behind heating and cooling. Saving energy can help your bottom line. Drain water heat transfer system Use the water you ve already paid to heat to preheat more hot water. Drain water heat recovery systems can recover heat from the hot water used in showers, dishwashers and clothes washers. Swimming pool covers Don t let your energy dollars swim away. Save up to 70% on heating costs by using a pool cover. Pool covers reduce heat loss and water evaporation and save you money. Spa and hot tub covers Relax, we ve got you covered, with a rebate that is. A well-insulated spa or hot tub cover traps in the warmth of your hot tub or spa and reduces water evaporation. Water heaters Use of a high efficiency water heater can cut your costs up to half, according to ENERGY STAR. Check out our water heating rebates on page 24. Find complete food service rebate qualifications on page 28. On the cooler side Alliant Energy can also help you to keep things cool with rebates on all sizes of new solid and glass door refrigerators and freezers. Cleaning up Serving all those delicious meals can result in a mountain of dirty dishes, pots and pans. Not to mention silverware! Alliant Energy helps you clean up for less with new commercial dishwasher rebates of $125 to $250. There are rebates on new commercial clothes washers too for all those aprons, towels and uniforms. Also of interest Check out rebates on refrigeration equipment including walk in strip curtains, evaporator fan controls and vending machines on page 25.

8 14 15 Commercial New Construction Plan ahead to maximize Alliant Energy s Commercial New Construction program provides complimentary energy design assistance and financial incentives to help offset the cost of implementing energy efficient strategies. The program is available to businesses that have new construction, additions or renovation projects before the design phase. A customized energy model simulates energy use for your project, demonstrating which strategies have the greatest impact and which are the most cost effective. Strategies are then selected by the building owner and the design team, assisted by the energy design consultant. Systems available for energy modeling include: Motors Energy-efficient motors pay for themselves The extra cost of an energy-efficient motor is often quickly repaid in energy savings especially when you factor in a rebate from Alliant Energy. Lower operating and maintenance costs coupled with relatively short payback periods make efficient motors a sound business investment. Industrial electric motors represent the single largest end use of electricity in the United States. The Department of Energy recently estimated that 25% of the electricity sold is consumed by industrial electric motors used to power production processes and heating, cooling and ventilation systems.

Alliant Energy has multifamily new construction rebates. Multifamily is defined as: Three or more units in one building shell Three stories or less Located on one lot with common space Minimizing operational costs can mean the difference between success and failure for many companies. Optimizing motor system efficiency can significantly reduce operational costs. That s where variable frequency drives (VFDs) come in. VFDs match the speed of motor-driven equipment to the process, simultaneously reducing operating costs and improving overall efficiency with typical energy savings up to 50%. Alliant Energy offers VFD rebates of $35 per horsepower of the motor being used. Multifamily rebates are calculated per square foot: Heating and cooling $1.00 per square ft. Heating $0.55 per square ft. Cooling $0.25 per square ft. Call today for a FREE Multifamily Energy Assessment. Our energy assessor will pinpoint where energy loss is occurring in your units, and what you can do to lower monthly energy bills and increase your property value.
