Nominal Interest Rate: Taken from another table Inflation: Manually inputted Values based on 2011 =+(1+inflation)*(1+inflation) =+(previous)*(1+inflation) Continued until final year 2013 Expanded Plan Residential Gas Screening Model –Avoided Cost tab Res heat Column C8 = 2013 numbers =+(corresp. inflation adj)*(value from other excel sheet) Replicated for Column Res Water NPV 1 =IF( C8 = “”, “”, NPV(Nominal_Interest_Rate, C$8;C8) * (1+Nominal_Interest_Rate)^.5 For each NPV Column it sues the previous column (res heat, res water, res other..) So NPV2 = IF( E8 = “”, “”, NPV(Nominal_Interest_Rate, E$8;E8) * (1+Nominal_Interest_Rate)^.5. E8 is 2013 Res Water

Manual Inputs: Row Number, Company, Sector, Program, Measure, Units Taken from separate excel sheet: TR Cost, Incentive, Annual CCFs, Life, Type, Water Gallons, Annual $ Peak Day CCFSs: =,00977*Annual CCFs =.00321*Annual CCFs Then repeated The rest are from separate excel sheet Unit Gas Benefit: =Calculation!P17/Input!F25 B/C: Unit Gas Benefit//Incentive If(B/C<1, “Bad”,””) *Note several “bads” 2013 Expanded Plan Residential Gas Screening Model –Input Tab

Avoided Cost: Manually Input Number: Manual input Calculation Factor: Manual Input Note: Red corners may mean an error with the formula 2013 Expanded Plan Residential Gas Screening Model –Peak Calculator Tab

All numbers are manual inputs so possible error with the table. The numbers don’t add up with the other numbers in the table. For example when adding together the CNG Home Energy Solution TR Cost for each Measure shown in the calculation tab the number isn’t $ Expanded Plan Residential Gas Screening Model –Peak Calculator Tab

broke down equations for columns shown here

Equation: IF($G19<>"",BO19*INDEX(Winter_Peak,$G19,0)*$AK19*1000*Inputs!S19,"") Logic Statement: $G19<>"" = not equal to 0 True: BO19*INDEX(Winter_Peak,$G19,0)*$AK19*1000*Inputs!S19 INDEX(Winter_Peak,$G19,0) (Look at G19 in “Measure Life”) False: “” = leave blank *constants are blue

Equation: IF($G19<>"",BO19*INDEX(Winter_Peak,$G19,0)*$AK19*1000*Inputs!S19,"") Logic Statement: $G19<>"" = not equal to 0 True: BO19*INDEX(Winter_Peak,$G19,0)*$AK19*1000*Inputs!S19 INDEX(Winter_Peak,$G19,0) (Look at G19 in “Measure Life”) False: “” = leave blank *constants are blue

Equation: IF($G19<>"",BO19*INDEX(Winter_Peak,$G19,0)*$AK19*1000*Inputs!S19,"") Logic Statement: $G19<>"" = not equal to 0 True: BO19*INDEX(Winter_Peak,$G19,0)*$AK19*1000*Inputs!S19 INDEX(Winter_Peak,$G19,0) (Look at G19 in “Measure Life”) False: “” = leave blank *constants are blue

The meaning of these value are unknown on both the calculations tab and the inputs tab. Calculations Tab:

Understanding the Quantity Column:

= IF(B6 <> “ “, IF(Inputs!H6>0, Inputs!H6, “ “), “ “) <> = not equal to ! = referring to cells on another worksheet $ = absolute reference H6 on Inputs Tab = 5% H6 on the Calculations Tab = 0 Before H19 the equation does not fit the value: **Starting at H19 on the Calculations Tab the equations calls upon Inputs!G, and the column begins to match those values in the respective Inputs G column Purpose: If the value in column B is not a blank, and if, in the Inputs tab, the value in the corresponding row in the H column is greater than 0, return that value. Understanding the Quantity Column:

Inputs Tab: Unknown Values

Inputs Tab: Measure Tables Randomly Placed

Energy Star Homes F218 = Number of homes Total = 150 F224 = Geo Commissioning rebates = 1 F225 = Central AC/Heat Pump rebates = 19 Low Income Energy Star F281 = Number of Homes Total = 50 F284 = Number of Oil Heat Homes = 0 F285 = Number of Propane Heat Homes = 0 Low Income F303 = Number of Electric heat Homes = 1,400 F304 = Number of Gas Heat Homes = 3,500 F305 = Number of Oil Heat Homes = 2,000 F306 = Number of Propane Heat Homes = 34 Residential Consumer Products HES G106 = Heat Pump Water Heater- New Unit = 100 G108 = Dehumidifier – New Unit = 50 G109 = Dehumidifier – Early Retirement = 50 G110 = Clothes Washer - E/DHW, E/DRY - New Unit = 50 G111 = Clothes Washer - E/DHW, E/DRY – Retirement = 50 Inputs Tab: Measure Tables One of the things mentioned specifically in the meeting is that these tables needed to be organized. They are currently randomly placed throughout the inputs tab.

Inputs Tab: Measure Life Measure Life (Column H): These are all input numbers
