Excel file simulates Quick PEP
Users of Quick PEP will handle data at different steps, e.g., energy use input
Score Cards are at Step 8 of Quick PEP
Calculations in Quick PEP will be invisible to users, but the Excel file is meant to allow testers to see what is happening

Facilities Score Card test tool, ver 1.0b
This Score Card is being developed for implementation in Quick PEP, Step 8 ver test-1.0b 4/29/2008For info on Quick PEP, go to the Best Practices website, Software Tools, first item
This test tool is intended to add capabilities for a rough, quick assessment of energy used by buildings at a plant, and gives a quick assessment of energy measures that can be considered for further investigation.
Go to the "How-To" Sheet (next sheet) to read directions on how to use this test Score Card

How to Use this test tool
STEP0 Go to the RESULTS sheet, Part 3, to see the example savings estimates
A Go to next sheet, PctFac, Part 1:1. Enter industry fraction(s) in column G,use "Other" if needed
The total in cell G33 should equal 100%2. If cell D16 is zero, then the value in cell D15 will be used in D193. If cell D16 is NOT zero, then the value in cell D16 will be used in D194. Only change values in G7:G31 or D16; do not change any other cells

Quick PEP Part 1
Percent Facilities Energy --------------->>>> # 1\/
Facilities Energy Score Card test version 1.0b SELECTIndustry Default Quick PEP Industry Facilities Energy
Facilities energy is only a fraction of total energy use Fractions Industry % of total that is facilities energyat industrial sites, sometimes small and sometimes large. 0 Ag, Forestry, Fishing 16%The defaults shown at the right are what Quick PEP assumes 0 Chemical 8%for specific industries, but you can set the actual percent here: 0 Aluminum / Alumina 3%
0 Cement 0%# 2 CHANGE the percent, item 'b' below if needed 0 Computers, Elec, Appl 40%
0 EAF Steel 8%Setting the percent of energy used by facilities 0 Fab Metal Prod 19%If you set a percent other than zero in 'b' it will be used instead: 0.3 Food, Bev, tobacco 15% a. Current default percent = 10.10% 0 Foundries 15% b. Percent to use instead = 28.00% 0 Furniture and related 16%
0.7 Glass and glass products 8%The percent value here will be used [do not change this ] 0 Heavy machinery 35% c. Percent that will be used = 28.00% 0 Integrated Steel 7%
0 Mining (except oil and gas) 0%0 Non-metallic mineral products 16%0 Oil and Gas extraction 16%0 Petroleum and Gas products 16%0 Petroleum Refining 8%0 Plastic and Rubber products 16%0 Primary Metals 16%0 Printing, Pub, allied 16%0 Textiles, Apparel, Leather Goods 22%0 Transportation equipment 29%0 Wood products, Pulp, Paper 7%0 Other 16%
100.00% Industry fractions should add to 100%.

Energy Percents
Excel file simulates calculations using percentages
Percents cascade from total plant to end uses to ECM savings
Electric is separate from fuel/steam
Simplified single percent of total plant energy that is facilities-related
End-use breakout percents for electric and fuel/steam
Technical savings percents by end-use for electric and fuel/steam
11
How-to Steps B-EB Go to the sheet after that, end-use, Part 2:
1. You may not need to change anything on this sheet2. If you need to change some values, change in the columns specified
The sums in row 20 should not be changedThe sums shown in row 20 should equal 100%
3. Only change values in B15:E19; do not change any other cells
C Go to the sheet after that, RESULTS, Part 3:1. Make sure cell D7 is the same as cell D19 in Sheet "PctFac"2. Make sure the values in rows 12-16 match the data in rows 15-19 in Sheet end-use
"end-use" columns B and C should match "RESULTS" columns C and D"end-use" columns F and G should match "RESULTS" columns E and F
3. Do not change any cells on this sheet
D Go to the "Scorecard" sheet, Part 4, Fill out or change the scorecard values according to your assessment of the plant or buildingThe assessment must cover the facilities included in the total energy data entered in Quick PEPDo not change any TOTALS on this sheet; only enter responses in column D
E Return to the RESULTS sheet, Part 3, to see the savings estimates

Columns D and E, Part 2
Columns D and E need explanation
These percentages are the “technical maximum” potential savings for the particular end uses
E.g., when the envelope needs a lot of work, and the best possible set of envelope measures is installed, 30% of envelope-related electrical and steam might be saved
In the final Score Card, we need to think about how users might be able to change these directly

Desired Feedback 1
User suggestions are welcomed regarding appropriate end-use breakout data Regional values might be appropriate if you
can provide - estimate – develop
Suggestions on how to handle user specification of facilities energy is also welcomed (go to the Quick PEP web app, start a dummy case, and go to Step 7)
Suggested values or methods on handling maximum possible savings by end use are also welcomed
16
Launch Quick PEP with dummy case
Go to website (see p 2 of this presentation)
Select Launch Quick PEP
Pass Step 1 by entering (dummy) Case Name and picking any industry besides “Other”
Click the Next button
17
Select Step 7 at the top for facility
Step 7 provides default percent “process” breakouts
One “process” is Facility Energy Use
Users can enter the appropriate values for facilities energy percents here
One page for electricity and one for fuel /steam

Back to the EXCEL file: Scorecard Questions, Part 4 Once all the
“percents” are acceptable, the Scorecard questions are answered (6th sheet in file)
Questions are asked for envelopes / infiltration, lighting / daylighting, space conditioning, ventilation, and misc hot water
