Title


    Summary/Description of module:  Should include a short technical history of the potential application of the energy conservation opportunity module as applied to energy and monetary savings.


General Rules of Thumb: (will vary according to module type:  should include rules of thumb typically observed in industry where energy efficiency is effectively practiced.   The following shows a typical example applied to a lighting recommendation.  Tables and graphs containing data essential to a recommendation calculation should be included here and targeted to increase the speed of data access.

  • The average cost of electricity is $0.05/kWh
  • There are 2000 hours per year per shift (based on the assumption that one shift is 8 hours per day, 5 days per week, 50 weeks per year)
  • Average cost of lighting:  The following table gives operating costs and light output data for various lighting types. The tabulated data include ballast contributions.
  • Lights generate heat at a rate of 3.4 Btu/hr/watt of energy consumed.lESNA (Illuminating Engineering Society of North America)

Notes:  (The following notes should be common to most modules unless it contains a more comprehensive pay back period and implementation protocol.)

Before choosing the following targeted recommendations READ THE FOLLOWING:

Pay back estimates for the following recommendations will use the equation below. They will vary depending on the, application, type of installation, and purchase quantity of material and labor associated with each recommendation.  It will be up to the person doing the analyses to use the URL references below each equation to help estimate an implementation cost.

The data correlating to the variables below each equation will be prompted for in order to execute a calculation. Frequently the fuel cost (FC) associated with the specific recommendation will be prompted for in order to calculate the annual cost savings (ACS). Unless otherwise specific to a particular recommendation the ACS will be calculated as follows:

    Variable description:  Should include variable definitions with correct units, how data should be acquired,  and equipment needed to collect data.  Also may includes links where data can accessed for a specific calculation.
    N = number of fixtures/lamps/ballasts to be removed
    EU = energy use per fixture/lamp and/or ballast, BTU/hr
    LH = number of hours lighting is used per year

    Calculation resources: Should include active calculator, active data conversion table, links to data tables and graphs at the top of the recommendation
