4 Payback What is payback? Payback is the amount of time it takes for the savings earned by your upgrade to equal the cost of the upgrade, or “pay it back.” Future savings depend on the accuracy of calculations, equipment performance, and energy prices. Restaurant Energy Cost Breakdown Lighting 10% Ventilation, 6% Cooling, 7% Water Heating 16% Other, 4% refrigeration 16% Note: Computers and office equipment total less than 1 per cent. May not total 100 due to rounding. © E Source, data from Energy Information Administration Cooking 25% Space Heating 17% To make an informed decision, look at both the expected return or cash flow projection, and the risk that the return will not be achieved. Also, weigh other benefits of energy efficiency measures, such as improved building comfort, increased building value, and reduced greenhouse gas emissions. Simple payback If you want to install new equipment or adopt new measures, simple payback will indicate the amount of time needed for energy savings to equal the purchase price. For example, if a new energyefficient measure costs $10,000 and saves $1,000 in energy costs each year, the simple payback is 10 years. You can estimate simple payback on new lighting using the Simple Payback Calculator on Natural Resources Canada’s (NRCAN) website at: http://oee.nrcan.gc.ca/ commercial/technical-info/tools. You can also view simple calculations of how much you could save by using more efficient equipment at: http://oee.nrcan. gc.ca/commercial/equipment. Incremental payback If you are installing a new type of equipment or if your old equipment is at the end of its life-cycle, incremental payback will tell you the length of time needed to pay for the difference between an efficient and less efficient unit. For example, suppose that an energy-efficient replacement model costs $700 and a less efficient model costs $500. If you can save $100 a year by buying the efficient model, the incremental payback of the efficient replacement model is two years, compared with buying the less efficient replacement model. Please note that some applications do not differentiate between simple and incremental payback.
Appliances Did you know... that approximately 25 per cent of the energy consumed in a commercial kitchen is from the appliances used in food preparation? How you use your appliances is just as important as which appliances you buy. Visit www.hydro.mb.ca/psfb to see if there is a Power Smart program available to help your restaurant serve great food while saving energy and money. To ensure your equipment works efficiently, start with these general tips: Read the owner’s manual: The owner’s manual has information to help you operate the appliance at its highest efficiency. Determine appliance start-up times: Turning on all of the appliances first thing in the morning means energy is being wasted. Choose start-up times for each appliance, so that they are ready to use when needed. Ensure optimal temperatures: Appliances can overheat and run at too hot a temperature. Routinely check each appliance to ensure it runs at its optimal temperature. Cleaning and maintenance: Routinely clean every appliance to eliminate food build-up. Dirty appliances can have inefficient heat transfer that results in uneven cooking and can cause break-downs. Follow the maintenance recommended in your owner’s manual. Recalibrate your equipment to help maintain efficiency: Equipment, such as thermostats and control systems, can fall out of calibration. Check and recalibrate to ensure you cook at the right temperature. Repair or replace broken control panels on ovens, steamers, and other appliances that feature control systems. Check pilot lights: Typically, older gas-burning appliances have pilot lights, which use a constant stream of gas to stay lit. Check pilot flames to make sure you use only as much gas as you need. You can spot an over-fired pilot light by its tall yellow flame. Adjust flames so they are bullet-shaped and mostly blue. 5
