Defining Quality Work and Enhancing Consistency in the Home Performance Industry
2 eere.energy.gov
Project goals: – Document industry-defined quality work and
its outcomes– Certify a highly-skilled workforce– Build a stable, growing industry
To meet the goal we must: – Define quality work– Train workers on what they should know
and be capable of doing– Provide professional certifications that
verify worker qualifications
Project Overview
3 eere.energy.gov
• Collaborative effort between DOE and the home performance industry– Experience from 30 years of DOE’s
Weatherization Assistance Program (WAP)– Extensive industry input—2,000+ industry
members, thus far
• Consists of three components1. Guidelines for Quality Work2. Guidelines for Effective Training3. Guidelines for Professional Certifications
Project Overview
4 eere.energy.gov
Standard work specifications: – Define minimum requirements for and expected
outcomes of high quality work – Reference relevant codes and standards
For:– Single-family homes– Multifamily dwellings– Manufactured housing
Guidelines for Quality Work
5 eere.energy.gov
Example: Standard Work Specification
Row Title Specification(s) Objective(s)
1. Hazardous material
removal
Health concerns in the removal and
replacement of equipment (e.g.,
asbestos, other hazardous
materials) will be identified
Written notification will be
provided to occupants of the
discovery of hazardous material,
including contact information for
regional EPA asbestos coordinator
Occupant will be asked to contract
with an EPA‐certified asbestos
contractor to conduct abatement
before equipment removal and
replacement (occupant is
responsible for abatement or
remediation)
Remediate health
hazards using EPA‐
certified contractors
Topic: Water Heating Subtopic: Installation and Replacement
1. Detail Name: Storage Type Appliance
Desired OutcomeSafe and reliable hot water source provided that meets occupant needs at lowest possible cost of ownership
6 eere.energy.gov
Example: Standard Work Specification
1.Equipment removal
Accepted industry procedures and practices will
be followed to:
Remove old water heater and associated
components Seal any unused chimney openings Remove unused oil tank, lines, valves, and
associated equipment
Ensure the safety of the workers
and occupants
Preserve integrity of the building
Remove old equipment in a
timely and efficient manner
1. New equipment
installation
New water heater and associated components
will be installed according to accepted industry
standards and practices, and manufacturer
specifications
The system will be installed to be freeze
resistant
Any existing water leaks will be repaired before
installation begins
Any penetrations to the exterior of the home
created by the installation of the equipment
will be sealed
Ensure the safety of the workers
and occupants
Preserve integrity of the building
Remove old equipment in a
timely and efficient manner

Example: Standard Work Specification
1.Emergency drain pan
An emergency drain pan will be installed a
minimum of 4”
above floor if leakage would
cause damage to the home
A ¾”
drainline or larger will be connected to
tapping on pan and run to drain or pumped
to daylight
Collect and safely dispose of
water escaping from the
storage tank
1.Expansion tank
A stainless steel bladder expansion tank will
be installed on the cold water side
A direct connection with no valves between
the storage tank and expansion tank will be
installed
Protect the storage tank from
expansion
1. Temperature and pressure
relief valve
Correct temperature and pressure relief
valve will be installed according to
manufacturer specifications
Temperature and pressure relief valve
discharge tube will terminate within 6”
of
the floor, or as prescribed by local code
Discharge excessive energy
(pressure or temperature) from
storage tank to safe location

Example: Standard Work Specification
1.Di‐electric unions
Di‐electric unions will be installed according to
manufacturer specifications Break the stray voltage electrical
circuit through the storage tank
1.Backflow prevention
Backflow prevention will be installed according to
manufacturer specifications and all applicable
codes
Protect water supply from
contamination
1.Thermal efficiency
Additional tank insulation (R‐11) will be provided
when necessary and where not prohibited by
manufacturer
If additional insulation is installed, it will be
installed based on fuel type, making sure not to
obstruct draft diverter, pressure relief valve,
thermostats, hi‐limit switch, plumbing pipes or
elements, and thermostat access plates
The first 6’
of inlet and outlet piping will be
insulated according to manufacturer
specifications
Pipe insulation must remain 3’’
from gas water
heater vent
Heat traps will be installed on the inlet and outlet
piping where not provided by manufacturer
Reduce standby loss from near tank
piping and storage tank
Ensure insulation does not make
contact with flue gas venting

What’s Next: Guidelines for Quality Work
10 eere.energy.gov
• Based on four Job Task Analyses:– Energy Auditor– Installer/Technical– Crew Leader– Quality Control Inspector
• DOE enlisted the Interstate Renewable Energy Council (IREC) to accredit training programs that equip workers with strong skills
• Accreditation ensures consistency and third-party validation across all training providers and programs
Guidelines for Effective Training
11 eere.energy.gov
• Training providers can begin developing training programs for accreditation based on Guidelines materials– Additional information available at http://irecusa.org/
• IREC is accepting applications for training provider accreditations at ww.ispqusa.org

What’s Next: Guidelines for Effective Training
12 eere.energy.gov
• Certifications create nationally-consistent credentials that employers and consumers can trust
• Four certifications are under development:– Energy Auditor– Installer/Technical– Crew Leader– Quality Control Inspector
• The certifications will require:– Experience in the field– Written and practical exams– Continuing education to maintain the certification
Guidelines for Professional Certifications
13 eere.energy.gov
• NREL issued a competitive solicitation and selected the Building Performance Institute to administer the initial certifications
• Certifications will roll out in 2012
• DOE welcomes other certifying bodies to administer certifications too. NREL exploring ways to make multiple licenses for the certifications schemes available
• DOE exploring opportunities to support and strengthen other energy- efficiency related certifications in home performance industry

What’s Next: Professional Certifications
14 eere.energy.gov
• Workers
• Training Providers
• Consumers
• For Program Administrators, the project can:
– Provide a comprehensive set of work quality specifications– Reference relevant codes and technical standards– Provide a clear baseline for quality assurance that delivers expected
energy savings and reduce call-backs, risk, and program costs– Prevent the need for each program administrator to re-create a new set
of program technical requirements.
