• How do we train them?• What do they need to know?• What equipment do they need?

4

How Do We Train Them?• Conferences• Training centers• On-site training• Online training

5

ConferencesPro• Peer-to-peer exchange• Meet the experts• Many topics• New ideas• Current issues

Con• Travel cost• Production loss• Many may not be

able to attend• Time constraints

limit depth/detail• Hands-on

opportunities are limited

6

Training CentersPro• Comprehensive,

standardized training on selected topics

• Furnace labs & equipment set-up allow more hands-on training

• Required attendance• Environment lends

itself to certification if desired

Con• Time & expense

building &/or setting up facility

• Travel cost• Production loss

7

On-Site Training Pro• Local housing stock &

tools• More hands-on action• Training site can count

towards production• Less travel required

Con• Huge trainer effort,

burnout worries• Training site can be

less than ideal• A lot of scheduling &

prep work required • May try to tackle too

much • Class size very

limited• Possibility of bad

weather

8

Online Training Pro• Aside from bandwidth,

there is no limitation on class size

• No travel required• Content and

instruction are consistent across country

Con• No hands-on

component

9

How Do We Train Them?• 10 Weatherization training centers listed on WAPTAC:

– Corporation for Ohio Appalachian Development, Ohio– CASE Training and Energy Services Center, West Virginia– Indiana Community Action Association Training Center,

Indiana– PG&E Stockton Training Center, California– Weatherization Training Center, Pennsylvania– Montana Weatherization Training Center, Montana– Kansas Building Science Institute, Kansas– New River Center for Energy Research & Training, Virginia– Association for Energy Affordability, New York– Southwest Building Science Training Center, Arizona

10

Other Training Centers• NYSWDA Training Center, Syracuse, NY• Mobile Home Training Center, Lynchburg, VA• Community and Economic Development Association (CEDA),

Chicago, IL • Linn State Technical College, Linn, MO• The Learning Center at Sun Power, Denver, CO• Building Performance Center, Opportunity Council, Bellingham,

WA• The creation of a few more training centers were being

considered even before talk of ramp up• While not having official training centers, many states use local

agencies to host standardized weatherization training courses throughout the year

11

Training Centers• How much can existing training centers

realistically increase capacity?• How many new training centers are needed?• Who establishes new training centers?

– Existing training centers establish new satellite offices?

– State uses T&TA funds to create new training centers?

– Private, for-profit companies create new training centers?

12

Training Center Ramp Up• Increasing production from 150,000 to 1,000,000 per

year represents a multiplier of 6.7• 16 existing training centers x 6.7 = 107 • Start-up costs

– (107 – 16) x $180,000/center = $16,380,000• Ongoing operating costs

– 107 x $290,000/center = $26,390,000/year

13

Training Centers• How large should a typical new training center be?• How many trainers does a training center need?• Where are new training centers most needed?• How long does it take to establish a new training

center?• How much does it cost?• Facilities?

– New construction, conversion of existing building, existing vocational tech facility?

– What equipment and layout are best?

14

Other Training Resources• Private companies and non-profit organizations that

provide weatherization training:– R.J. Karg Associates, Topsham, ME– Saturn Resources Management, Helena, MT– Vermont Energy Investment Corporation, Burlington, VT– Wisconsin Energy Conservation Corporation, Madison, WI

• A small network of independent trainers offer varying forms of on-site training

• State technical monitors• Peer-to-peer trainers

– Circuit rider• Local weatherization agency association trainers

15

On-Site Training• What is the existing capacity of this delivery

mechanism?– How many people new to Weatherization could the

existing on-site training capacity get trained in 6 to 9 months?

• How many traveling trainers could be added from the existing training network?

– How much would this increase training capacity?

16

On-Site Training• Where can we find new trainers capable of providing

comprehensive, hands-on, on-site training?– How many do we need to hire?– How long will it take to train the trainers?– What do they need to be trained on?

• What vehicles and equipment will traveling trainers need?

– Fully outfitted crew truck or trailer and tow vehicle?– Multiple manometers and combustion analyzers so more

than one student can push buttons and see screens at a time?

– Training props

17

On-Site Training Ramp Up• “Non-training-center” portion of the training

infrastructure must also increase almost 7 fold• This crude estimation likely under-predicts need:

– Existing training infrastructure is struggling to meet current need in some areas

– Many new trainees will be starting from scratch instead of being on the job for several weeks or months

18

Online Weatherization Training• Online Weatherization training has many advantages:

– No travel– No limitation on class size– Many trainees can quickly become familiar with the

Weatherization Program and whole-house weatherization basics

– Subsequent hands-on training can start at an advanced level• Saturn Resource Management has developed online courses for

Weatherization providers, BPI certification, and HERS raters– Based on core competencies developed by Weatherization

Trainers Consortium– Available at http://srmi.biz/bpt/

• A separate, pilot online training module on zonal pressure diagnostics will be also be available online later this month

19

Distance Learning• Pennsylvania’s Weatherization Training Center and

others have offered distance learning on Weatherization and building science over the internet

• Model could be used by other training centers and independent trainers to extend their reach and capacity

20

Hands-On Training• Online training and distance learning are only part of

the answer• Hands-on training and on-the-job apprenticeship are

vital components to effective Weatherization

21

What do they need to know?• Core competencies• Standardized curricula

22

Core Competencies• Specialized knowledge and skills are required at the

local, state, and federal level to run an effective Weatherization Program

• While there is a general understanding of the competencies required, these had not been articulated on a national scale

• The Weatherization Trainers Consortium published a set of core competencies to increase awareness and raise expectations

• The competencies that a weatherization worker should possess depend on their position

– For example, an auditor needs to conduct diagnostic testing that may not be required of an installer

23

Core Competencies• The point of entry also dictates which core

competencies are required– An entry-level installer requires a minimum set of

competencies. – This installer must acquire additional skills to become a

crew chief, and still more to become an auditor– A new auditor hired off the street must already possess

auditor-level competencies as a condition of hire• These increasing levels of competency also provide a

career or development path for agency and contractor personnel

• The core competencies document and matrix is available on http://waptac.org/si.asp?id=1259
