Industrial Buildings Score Card Tool
ver 1.1This Score Card is for scoping potential energy savings from Buildings
energy measures at industrial sites
This tool does not handle process heat recovery for building energy
purposes, although inputs can be adjusted to approximate some
possible heat recovery measures; nor does it treat appliances or office
equipment. 10/22/2008
This tool provides capabilities for a rough, quick assessment of energy
used by buildings at a plant, and gives a quick assessment of energy
measures, based on annual energy use and costs, that can be considered
for further investigation.

How to Use this tool
NOTES: Users enter total electricity use and fuel/steam estimates on the Energy sheet.
Users may want to calculate total annual fuel/steam with a fuel calculator prior to entry.
Cells for users to change are highlighted like this.
STEP
0 Go to the RESULTS sheet, Part 5, to see the example savings estimates
1 Go to next sheet, PctFac, Part 1:
1. Enter industry fraction(s) in column G, usually only one value will be 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 D19
3. If cell D16 is NOT zero, then the value in cell D16 will be used in D19
4. The value in cell D19 will be used on the Energy sheet to initially estimate energy
2 Go to the sheet after that, Energy, Part 2:
1. You must enter the total annual electricity and fuel/steam use for the applicable
site where the buildings are located in row 11, columns B and C
2. Electricity use is in kWh/yr, and Fuel/Steam use is in Million Btu/yr
3. You must enter the total annual electricity and fuel/steam COSTS for the applicable
site where the buildings are located in row 15, columns B and C
4. This sheet sets the total Buildings electricity and fuel/steam use and costs
Both energy use and costs for electricity and fuel/steam are estimatedThe values in row 30 are the annual Buildings use, and row 35 is annual costs
5. The Buildings energy and energy cost total can be adjusted if needed
Energy use adjustments are made by changing the percentages in row 28
Energy COST adjustments are made by changing the percentages in row 33
3 Go to the sheet after that, end-use, Part 3:
1. You may not need to change anything on this sheet
2. If you need to change some values, change in the yellow cells
The sums shown in row 21, columns B and C should equal 100%
4 Go to the "Scorecard" sheet, Part 4,
Fill out or change the scorecard values according to your assessment of the plant buildings
The assessment must cover the buildings included in the total energy data on the Energy sheet
Do change the EXAMPLE entries that are there now, to reflect the building(s) being evaluated.
Scorecard values indicate savings potential, so higher values mean more savings potential.

Buildings Energy Measures Score Card version 1.1
SCOPE The buildings score card addresses the potential energy savings of building energy
systems found at industrial sites in four major categories of envelope / infiltration,
lighting, space conditioning, and ventilation. Users can obtain savings estimates for
any or all of the four major system types.
APPROACH The approach differs from the typical Best Practice view of scoring how good things
are, since best practice energy systems in buildings have been found to be very poor
too often. This situation occurs because building systems are complicated and
people find surprisingly many ways to make systems not work properly. In addition,
because most people are unaware of how best practice systems can become very
poor in actual use, they would often be unable to answer correctly how "good" their
systems are. So the Score Card instead asks users to identify major potential areas
for improvement, based on typical measures found in industrial plants by the IAC
program.
The Buildings Systems Score Card will help users to:
a) Develop a greater awareness of potential building energy measures;
b) Identify possible major categories of building system measures to reduce
energy costs;
c) Provide users with rough estimates of total energy savings for each system type
and the total for all four types.
AUDIENCE FOR THE TOOL The audience for this tool is facility managers or facility energy managers for
industrial plants.
HOW TO USE BUILDINGS SCORE
CARD
Users enter the answers to the questions for each energy system type. The answers
to the questions generate scores that are applied to the facilities energy percentagesdeveloped by the Industrial Technolgies Program for specific industies (see second
followin sheet < PeuPct> .
RESULTS Results of the Score Card are presented for each of the four major energy systems
and a total. The savings potentials are given both in energy units and dollars for the
energy categories of Electricity and Fuel Use/Steam.
MAXIMUM SAVINGS POTENTIAL
METHODOLOGY
The calculations in this version use a fixed maximum percentage possible savings
for each of the four major system types by energy category of electricity and
fuel/steam. This percentage is now fixed for all industries, and extensive analysis is
expected to be needed to develop these values for each industry individually.
