ABSTRACTPresented is a guide for developing lessons for a

home weatherization course that promotes the use of retrofittechnology to conserve energy in residential housing. The course isintended to cover processes and causes of building heat loss, andhome retrofitting procedures. Each lesson description contains a listof points the instructor should emphasize and recommended visualaids. Although these lessons are designed for a coarse forsupervisors of work crews engaged in home weatherizaticn, theselearning activities are also appropriate for trades programs at thesecondary or postsecondary levels.

Foreword

Project Retro-Tech has evolved from efforts by theDepartment of Energy (DOE) to fill s need expressedby various consumer groups. On the one hand, Stateand local agencies that use Federal and State fundsto weatherize the homes of fixed- and low-Incomepeople have pointed out a need for a source oftechnical know-how to Improve the effectivenessof their weatherizing measures, either in terms ofhigher fuel savings or reduced installation cost.

On the other hand, many consumer groups havepointed out the difficulty In locating qualifiedtechnicians who specialize in weatherizing homes.Firms that sell either insulation or storm windowsand doors are not always properly staffed withtrained specialists who can make an overallassessment of thermal difiClincies andrecommend optimum corrective action.Misapplication or tack of attention to any keyelement In th4 total weatherlzation process cannegate the fuel and cost savings resulting from theinstallation of insulation and storm windows.

The shortamof skilled and trained technicianswho speCialize in weatherizing homes will be furtheraggravated during the next few years ashomeowneis turn to retrofit measures for relieffrom the higher cost of energy.

The expanding requirements for a large cadre ofskilled technicians who have been trained intechniques for weatherizing the homes of allIncome levels of the population will place additionalburdens on the vocational-technical schools at thesecondary, postsecondary, and adult educationlevels. The Home Weatherization Course developedby DOE is designed to assist the vocational-technical schools to meet this challenge.

The DOE Wutheritstion Manual, however, isonly one of a serlfis of training materials beingdeveloped by DOE, Department of Housing andUrban Development (HUD), and private industrygroups. These additional training materials, whenthey become available, will enable the vocational-technical schools to expand the content of theinitial Home Weatherization Course. In addition,they will be able to add other courses to train thespecialists needed to till the many new Jobsresulting from the increased emphasis on homeweatherization.

This booklet was prepared as a guide to instructors

In developing lesson plans for a HomeWeatherization Course that promotes the use of

known RETROfIt TECNnology to improve thermal

characteristics and conserve energy In residential

housing.

Although the suggested lesson piens contained in

this booklet have been designed for a special

course for supervisors of workcreva actually

engaged in home weatherizatIon, the conceptsembodied in the individual lessons cie also beincorporated into the curriculum of constructiontrades programs at vocational-technical schools at

the secondary, postsecondary, or adult education

levels.

DOE welcomes your Ideas and comwents about the

Home Weatherization Course. in addition, we would

appreciate information from you regarding your use

of the training materials, either for special groups or

for vocational students pursuing a career In the

construction trades. Your comments, along with

any suggestions for improving the training materials

should be mailed to:

1. The Weetheri=tion Manuel end Job Bookare based on known technology for retrofittingresidential hoUsing. The principal objective ofthe course on Home Weatherization Is to traincommunity service groups to use availabletechnology when retrofitting residential housingunder government-assisted weatherizatlonprograms. Retrofit measures can be aneffective means for improving thermalcharacteristics of housing and reducing energyuse.

2. A secondary objective of the course Is toimprove the vocational and avocationalopportunities of young people and adultsenrolled In both the accredited andnonaccrsdited construction trades programs bypreparing students for the new business andemployment opportunities resulting fromincreased emphasis on home weatherizatlon.

B. initruclional Objectives

1. Estimation: Given the physical dimensionsand construction features of detachedresidential structure, a student will prepare forthe homeowner a written analysis (job book),containing the following:

a. Identification of gross thermal deficienciesof the structure that result in heat losses byinfiltration and conduction;

b. Comparison of current heatingrequirements with the potential fuel andcost savings;

c. Job writeup, from which the materialspecifications and bill of materials willbe prepared;

d. Bill of materials for the feasible remedies,Including costs and payback period.

2 inatalletion: Given the job writeup (job book)for detached residential structure, the studentwill describe and/or demonstrate to othersthe proper methods for Installing the specifiedmaterials. In addition, the student willdescribe and/or demonitrate the method forconducting a post-evaluation at the end ofheating season to determine the actual energysaved by a retrofit program.

C. Equipment Required

The following equipmant is required for theclassroom lectures and/or demonstrations:

1Projection screen1Overhead projector

1Set of transparencies (prepare fromcharts contained in supplement to thisguide)

1Set of 35 mm slidesoptional (may beobtained on loan from the FEA RegionalOffice)

F. Instrintional Strategies

1. Course for Work-Crew Supervisorsin cooperation with the State Energy Office,

State Board of Education, and other appropriate

State offices, technical-vocational schools are

encouraged to offer this 8-12 hour training

course to work-crew supervisors, foremen, or

estimators who are engaged in government-

assisted programs for weatherizing the homes

of fixed-and low-Income people.

2. Post-Secondary and/or Secondary Vocational

Technical ProgramFor students who are pursuing a career in

residential construction and/or retrofitting

field, the vocational-technical schools areencouraged to modicy their vocational programs

by ir=rporating one or more of the lesson

units into such related courses as carpentry,

residential wnstruction/rehabilitation, and

heating, ventilating, and air-conditioning.

3. Adult Education ProgramFor adults who wish to enhance their vocational

or avocational opportunities, the vocational-

technical schools are encouraged to conduct

noncredit courses in home weatherization

based on training materials developed by FEA

and others.


G. Format of Leeson Plans

The lesson plans starting on the facing page

contain "points of emphasis" to be covered by the

instructor during the classroom lecture. Adjacent toeach emphasis point is a page reference In thestudent's manual and the chart number of the

visual aid to be used to reinforce the emphasis

point.

The visual aids, either transparencies for overhead

projection or 35mm slides, should be prepared lo-

cally froM a set of 8" x 1014" charts contained In

a Separate package that accompanies this instruc-

tor's guide. Each chart is numbered to coincide

with the appropriate point of emphasis.

For the convenience of the instructor when

reviewing a lesson plan, each chart appears in

1. Heat is lost by cold air coming in and warm air going out. Thisleakage or infiltration is caused by two factors:

7 C-25

(a) Infiltration by Hind occurs when wind flows in on one sideand warm air flows out on the leeward side.

7 C-26

(b) Infiltration by "Chimney Effect" occurs when Inside air iswarmer than outside air. The building acts like a chimney:

7 C-27

heated air, which tends to ?lee, leaks out of cracks and Isreplaced by cold air, which is sucked In at lower levels.

(Refresher from introduction Section)Nome WeathedutIon Is a Four-Step Process:

(a) Step 1Inspect the building to determine its constructioncharacteristics.

(b) Step 2Calculate the heat losses from the building.

(c) Step 3 Evaluate the building characteristics and heatlosses to determine what measures should be taken.

(d) Step 4Install the weatherizing materials.

The job book is designed to enable a work-crew supervisor (orJob estimator) to follow this four-step process in a systematicmanner.

Perhaps, the best way to become familiar with the job book is tosimulate the process by working out an example of a buildingto be weatherized.

The charts that you will see have been marked up to show theinformation that an estimator will obtain when he inspects thebuilding to determine the construction characteristics.

Purpose of Lesson

This lesson will enable the intructor to evaluate the degree towhich the Instructional Objectives have been achieved.

Evaluation of instructional Objective No. 1: Estimation

(a) Objective: Given the physical dimensions and constructionfeatures of a detached residential structure, a student willprepare a written analysis (Job book) containing thefollowing:

(1) 'identification of gross thermal deficiencies of the struc-ture which result In heat losses by Infiltration andconduction;

(2) Comparison of current heating requirements with thepotential savings;

(3) Job writeup, from which material specifications and billof materials will be prepared; and

(4) Bill of materials for the feasible remedies, includingcosts and payback period.

(b) ProcedureA preferred and an alternate procedure are suggested. Thepreferred procedure is a field exercise that Involves theinspection-calculation-evaluation steps of the four-stepweatherizing process covered In lesson plans 5A, 58 and 5C.The alternate procedure Is a classroom exercise that Involvesthe calculation-evaluation steps only.

(c) Field Exercise(1) inspection: Arrange for class to visit a nearby nome that

has simple construction characteristics (one-story andsimple floor plan).

(c) Field Exercise (continued)

Working independently or in assigned teams, eachstudent will record the physical dimensions and con-struction features called for In the job book on pages 2,4, 5, 6, 9, and 11. (To insure uniformity, the teacher willprovide the student with the dwelling and heating systeminformation called for on page 3.)

(2) Calculation-evaluation: After returning to the classroom,the data obtained by students will be discussed by theclass to resolve differences. Then, each student willindependently perform the calculations and evaluationcalled for In steps 2 and 3, and record the answers in theJob book.

At the conclusion of the exercise, the answers will becompared and the differences discussed. (If appropriate,the Job books will be collected by the Instructor forgrading and/or evaluation purposes.)

Evaluation of Instructional Objective No. 2: Installation

(a) Objective: Give a Job writeup (Job book) for a detachedresidential structure, the student will describe and fordemonstrate to others the proper methods for installingthe specified materials.

(b) Procedure: Due to the wide variety of possible instructionalsituations, no standard procedure will be given here.

An Ideal procedure would be for the instructor to makearrangements through a community service agency thatIs involved in weatherizing homes, to have the classinstall the weatherizing materials purchased by thatagency.

If this is not practical or feasible, the instructor Isencouraged to design an evaluation procedure based onthe method of instruction employed In lesson 5D.
