12 Energy Cost Model The test results can be used to estimate the annual energy consumption for the double rack oven in a real-world operation. A simple cost model was developed to calculate the relationship between the various cost components (e.g., preheat, idle and baking costs) and the annual operating cost using the ASTM test data. The cost model incorporates the set back mode during idle periods, which is the normal operating state for this double rack oven. Daily Oven Operation Assumptions Total Operating Time per Day (h) 12 Operating Time in Set Back Mode per Day (h) 3 Operating Days per Year (d) 365 Number of Preheats per Day 1 Total Amount of Food Baked per Day (lb) 1,200 Based on the assumptions above, total daily energy consumption was determined by adding the daily preheat energy consumed, the daily idle and set back energy consumed, and the daily baking energy consumed. It is estimated that the Belshaw Adamatic OVEN-2020 Double Rack Oven would consume 1,928 therms of gas and 3,654 kwh of electricity annually. Using a rate of $1.00/therm and $0.15/kWh, the estimated operational cost of Belshaw Adamatic OVEN-2020 Dual Rack Oven is $2,476 per year. Estimated Single Rack Oven Energy Consumption and Cost Gas (Btu) Electric (kwh) Daily Preheat Energy 37, Daily Idle Energy 81, Daily Set Back Energy 15, Daily Baking Energy 393, Total Daily Energy 528, Annual Gas Consumption (therms/yr) a 1,928 Annual Electric Consumption (kwh/yr) 3,654 Total Annual Cost ($/year) b $2,476 a One therm = 100,000 Btu b Oven energy costs are based on $1.00/therm and $0.15/kWh.

13 Additions, Deviations, & Exclusions Additions: The following procedure was employed to evaluate the set back/energy-saving mode of the Belshaw Adamatic OVEN-2020 Double Rack Oven: -Enable the rack oven s set back mode. If applicable, set temperature and time settings per manufacturer s instructions -Preheat the rack oven to 400 F and allow to stabilize for the allotted set back temperature. -Once set back is engaged, allow the rack oven sufficient time to cool to the set back temperature. -Allow the rack oven to stabilize at the set back temperature for 2 h. -Monitor baking cavity temperature and rack oven energy consumption for an additional 3 h while the rack oven is operating in this condition. -Record and report the rack oven s gas energy rate, electric energy rate, and average cavity temperature for the 3 h in set back mode. Deviations: Heavy load baking-efficiency test #1 used a rolling rack that was stabilized at 0 F. Exclusions: None. ECP Page 13 of 18

14 ENERGY STAR Qualification FSTC testing of the Belshaw Adamatic OVEN-2020 Double Rack Oven resulted in an idle rate of 20,578 Btu/h and an energy efficiency of 66.1%. The results comply with the ENERGY STAR Program Requirement for Commercial Ovens, Version 2.2 ECP Page 14 of 18
