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.
