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 present colors closer to natural light. High bay Lighting in warehouse, retail, manufacturing and industrial environments with ceiling heights greater than 20 feet is a 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 Replacing outdated High Intensity Discharge (HID) fixtures with specially designed T8 or T5 fixtures can have a simple payback as little as two to four years.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 1.5 in diameter, it is likely an inefficient T12 lamp. T 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 the number of screw-in bulbs in your office, break room, restrooms and storage areas. Consider the savings for one bulb. Bulb type Incandescent 60 watt bulb CFL watt bulb LED 6-8 watt bulb 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 Operating cost $17.86 per year $4.61 per year $2.08 per year 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.

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 heating ventillation and air conditioning (HVAC) tuneup rebate! System tuneup Keep your current HVAC equipment working at its best. With our 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 key card 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 thermostat 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 devices. Insulation and air sealing What s the number one way to save energy? It s insulation. Start with a free Small 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 pages

6 10 11 Refrigeration Keeping it cool Walk-in strip curtain Anti-sweat heater control Refrigerated glass display cases use anti-sweat heaters to prevent moisture from forming on their glass and frames. Most typically operate 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%. It s low-tech, easy to install, uses no energy to operate and continuously saves 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! To qualify for a rebate, the 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 controller Evaporator fans typically run at normal speed all the time, regardless of demand. An evaporator fan controller will automatically adjust fan speed, without impacting the overall temperature of the cooler or freezer. To qualify for a rebate, the fan motor power must be reduced by at least 75% when the compressor(s) cycle off. Electronically commutated motor 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 an electronically commutated motor (ECM) can significantly reduce energy consumption and your energy bill. To qualify for a rebate, the shaded-pole or permanent-split capacitor evaporator fan motors must be replaced. Scroll compressor Scroll compressors not only use less energy, but have significantly fewer moving parts, resulting in superior performance, lower maintenance cost and greater reliability. To qualify for rebate, the reciprocating compressor must be replaced. Display case night cover Leaving display coolers uncovered at night can waste a lot of energy. Using night covers on display coolers lowers heating and air conditioning costs. To qualify for a rebate, you must install a cover on an existing open refrigerated display case. For a list of all refrigeration rebates see page 25. Refrigeration tuneup Keep your refrigeration working at its best. With a new refrigeration tuneup rebate, there is one more reason to get an annual checkup to keep your equipment running at its peak efficiency.

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 dinners 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? It s typically the second biggest energy user, right behind heating and cooling. Saving energy can help your bottom line. Drainwater heat transfer system Use the water you ve already paid for to preheat more water. Drainwater heat recovery systems can recover heat from the hot water used in showers, dishwashers and clothes washers. Swimming pool cover 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, water evaporation and saves money. Spa and hot tub cover 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 heater Use of a high-efficiency water heater can cut your costs up to half, according to ENERGY STAR. Check out 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. Craving savings Check out rebates for vending machines on page 25.

8 14 15 Commercial New Construction Plan ahead to maximize A customized energy model simulates energy use for your facility, demonstrating which strategies have the greatest impact and are the most cost effective. Strategies are then selected by the building owner and their design team, assisted by the energy design consultant. Systems available for energy modeling include: Daylighting controls Load responsive equipment Envelope Outside air-control Heating and cooling Window layouts 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 estimates that 25% of the electricity sold is consumed by industrial electric motors used to power production processes and heating, cooling and ventilation systems. Lighting controls and design Find rebate information on motors and VFDs on pages Customers interested in the Commercial New Construction program should contact Alliant Energy before design development. This allows time to incorporate energy-efficient strategies into the building process. Multifamily new construction Multifamily is defined as more than three units in one building shell, three stories or less, located on one lot. The following multifamily buildings are eligible: Apartments Prisons Condos Senior living or nursing homes Dormitories Shelters Lofts Variable frequency drive Add variable frequency drives for even greater savings to your energy-efficient motor. 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%. For projects that don t qualify under Commercial New Construction, consider multifamily new construction. 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. For more information contact your dedicated key account manager or the Business Resource Center at ALLIANT.
