FOREWORD
The Energy Use Evaluation Workbook has been prepared by the Energy Division ofthe Montana Depart-
ment ofNatural Resources and Conservation (DNRC), for use in the Institutional Conservation Program (ICP).
This program which was authorized by the National EnergyAct of 1978, is designed to encourage energy conser-
vation improvements in buildings owned by schools and hospitals.
The workbook is based on a publication entitled: "Making Sense ofYour Energy Dollar," prepared for the
U.S. Department ofEnergy to assist states in preparing their own workbooks for the Institutional Conservation
Program. The program is managed in Montana by DNRC, and funded in pan by the U.S. Department of
Energy (DOE).
DNRC
While recommendations contained in this workbook have been reviewed for technical accuracy, and
DOE are not liable ifpotential cost savings identified in this workbook are not actually achieved. Neither ofthe
above agencies endorses or recommends the use ofany specific brand ofequipment which may be represented in
this workbook.
Special thanks to Mark Mines for compiling the material, Jim Bond for the cover photos, Dan Vichorek for
editing, Kerry Campbell for completing the word processing, and Ross Campbell for the graphic design and
layout.

HOW
TO COMPLETE
THE ENERGY USE EVALUATION WORKBOOK
The Energy Use Evaluation Workbook has been designed for quahfied evaluators to use in assessing potential
energy conservation projects in Montana's public buildings.
The workbook includes a step-by-step process for conducting an energy use evaluation and serves as aguide
for implementing and monitoring a comprehensive energy management program. The Energy Use Evaluation
Checklist (Step 2) identifies simple, low-cost or no-cost energy-saving operation and maintenance procedures,
O &
called Ms. The checklist also includes potential energy conservation measures (ECMs) which would require
engineering analysis to determine the energy savings and cost ofthe project.
The Energy Use Evaluation Workbook can be used to determine whether a detailed technical analysis ofthe
building's energy using systems should be completed. This analysis, which is called a Technical Assistance (TA)
Report, includes a list ofpotential ECMs and asummary ofthe energy savings and estimated costs.
THE INSTITUTIONAL CONSERVATION PROGRAM
Buildings that are potentially eligible for the Institutional Conservation Program (ICP) are public and private
nonprofit schools and hospitals built before May 1, 1989. Funding for theTechnical Assistance Report is avail-
able through the ICP Program.
The Energy Use Evaluation Workbook can be completed by people with different levels ofexpertise; building
operators with experience in energy conservation, utility energy analysts, and licensed engineers. The more
experience the Energy Use Evaluator has in energy conservation, the more valuable the completed workbook will
be in assessing the buildings potential for energy retrofit projects. ONE WORKBOOK SHOULD BE USED
FOR EACH BUILDING EVALUATED.
A completed energy use evaluation workbook and ICP grant application must be submitted to the ICP
Program Manager for aTechnical Assistance (TA) grant.
The ICP Manager will answer any questions concerning the workbook and the program. Please contact::

GUIDELINES FOR COMPLETING
WORKBOOK
THE ENERGY USE EVALUATION
STEP
1
Complete the Building Energy Consumption Inventory (pages 6-15). This will give a basic rundown ofthe
energy systems in the building, how much fuel, what kind offuel is used, and what the building's potential is for
installation ofsolar or other renewable energy systems. Instructions are included in this step.
STEP 2
Complete the Energy Use Evaluation Checklist (pages 16-39). This step is not required but will help evaluate the
energy conservation potential in the building. The items listed in the checklist cover common energy consump-
tion inefficiencies found in eight basic aspects ofbuilding operation: Administrative (the operation and use of
the building by people), Lighting. Building Envelope, Ventilation. Heating. Cooling. Water Heating and Special.
The letters used in the checklist numbering system correlate to the first letters ofthe eight basic aspects ofbuild-
ing operation, such as A-1 L-2, orV-3. The evaluator should walk through the building and determine whether
,
each ofthe checklist conditions exists. Indicate by checking either the "Yes" or "No" box under the "EXISTS"
column. Then check either the "Yes" or "No" box under the "RECOMMENDED" column for each listed O Sc
M. Once you have gone through all items in the Energy Use Checklist, complete Step 3.
STEP 3
Create a list ofpotential Energy Conservation Measures which exist in the building. Include a briefdescription of
the ECM, estimated cost ofproject, estimated savings, and estimated simple payback.
STEP 4
Complete the Evaluator Information Form on page 43.
STEP
5
Send the original and one copy ofthe Montana Energy Use Evaluation Workbook along with the application to
the Montana Department ofNatural Resources and Conservation, Energy Division. This step is required to
verify the building's eligibility forTechnical Assistance funding under the Depanment ofEnergy's Institutional
Conservation Program.
