A word about electric rates - they vary considerably. Think about blended rate averages for most projects, or cents per kilowatt hour with a demand factor of $ per Kilo Watt (KW) or more complex rates with summer and
winter rates and time of use meters. If you can give us the utility electric rate schedule then we can look up the correct information from the utility.
EC
motor ROI calculator
This MS Excel file allows complete customization of the ROI model. Specific electric rates, power figures, motor and store densities, rebates, and maintenance figures all can be input. Coupled with a detailed survey of several stores, this calculator can provide a very sharp estimate of the actual energy savings that is possible by retrofitting existing shaded pole evaporator fan motors with new electronically commutated motors.
Computer software energy management ROI calculator
This Excel file allows the user to accurately model the computer energy environment with respect to electric rate, computer leave on rates, average computer power, and various energy conservation policies. The output is break-even and annual savings.
Compact florescent replacement of incandescent lighting calculator
This ROI calculator provides for varying the electric rate and demand (KW) charges for a mix of wattages for incandescent light and compact fluorescents. The model also supports the impact of refrigerated environments such as walk-in coolers and freezers.
ROI Energy Calculator for Airius Products
This Excel files allows for a quick an accurate estimate of the return on investment of the installation of Airius units. Key variables that are to be entered are: size of building, insulation, cost of gas, temperature differential between floor and ceiling, rebate information and electricity costs. The program will output, the annual energy savings and a series of break-evens based on energy, rebates and maintenance savings.
