What is Weatherization?
 Nation’s core program for delivering energy efficiency services to
low-income homes
 Operates in every state, District of Columbia, among Native
American tribes, and U.S. Territories
 Services delivered to single-family, multi-family, and mobile homes
5 | Weatherization Assistance Program: Overview
eere.energy.gov
Types of WAP Services
 Energy audits conducted
 Furnace service
 Air infiltration reduction using
blower doors
 Furnace replacements
 Attic and floor insulation
 Duct system balance and
sealing
 Dense-pack wall insulation
 Duct sealing
 Domestic hot water heater
improvements
6 | Weatherization Assistance Program: Overview
 New refrigerators
 Energy efficient lighting
retrofits (CFL)
 Incidental repairs
 And more………..
eere.energy.gov
Heating System
 May need tune-up or basic
repairs
 Can replace hazardous or
inoperable furnaces
– Due to funding limitations,
leveraged resources often
used to replace heating
systems
– Un-vented space heaters
pose large health and
safety threat
7 | Weatherization Assistance Program: Overview
eere.energy.gov
Cooling System
 Technicians can tune-up or
repair cooling systems
 Ducts may require sealing
and/or balancing
 May add fans, ventilation for
health and safety
8 | Weatherization Assistance Program: Overview
eere.energy.gov
Air Sealing
 Blower door test quantifies air
leakage & identifies sites
 Panel with fan is placed in a
doorway to de-pressurize home
 Exaggerates leakage so it can be
measured and sealed
9 | Weatherization Assistance Program: Overview
eere.energy.gov
Infrared Camera
 Illustrates heat loss
 Guides air sealing and insulation
 Helps to educate clients
 Quality control for insulation and
other measures
10 | Weatherization Assistance Program: Overview
eere.energy.gov
Duct Sealing
 Duct system may need sealing and/or balancing
 Duct tape should NOT be used – Apply Mastic
 Ducts in unconditioned spaces should also be insulated
11 | Weatherization Assistance Program: Overview
eere.energy.gov
Pressure Pan
 Leaky ducts can increase
costs by 10-30%
 While blower door runs,
pressure pan placed over
air register
12 | Weatherization Assistance Program: Overview
eere.energy.gov
Manometer
 Manometer measures pressure
created by air leaking into
ductwork
 Results help locate large leaks
– Registers near leaks have
higher readings
 Duct blower can also be used for
more accurate readings and to
balance systems
13 | Weatherization Assistance Program: Overview
eere.energy.gov
Insulation
 Blown insulation most effective
– Holes discreetly cut in walls or ceiling
– Insulation is blown into space through a tube
14 | Weatherization Assistance Program: Overview
eere.energy.gov
Insulation
 Reduces air infiltration and heat loss
– Dense-pack insulation often installed before air sealing,
since it reduces leaks so effectively
15 | Weatherization Assistance Program: Overview
eere.energy.gov
Electric Base Load Measures
 Converting incandescent lighting to fluorescent
 Replacing refrigerators
 Replacing or insulating water heaters
 Reducing hot water use
 Reducing appliance usage through client education
16 | Weatherization Assistance Program: Overview
eere.energy.gov
Lighting
 Compact fluorescent lighting (CFL)
– Harps and other hardware
– Screw-in vs. pin base
 Hard-wired fixtures
– Savings may be more permanent
– Some state or local codes require
licensed electrician to wire fixtures
17 | Weatherization Assistance Program: Overview
eere.energy.gov
Refrigerators
 Must meter at least 10% of units
replaced
 2-hour minimum metering
 Association of Home Appliance
Manufacturers (AHAM) or
alternative databases can provide
energy use of existing
refrigerators
 Units not in database that are
metered count toward 10%
requirement
18 | Weatherization Assistance Program: Overview
eere.energy.gov
Water Heater
 Efficient water heater, low-flow shower
heads, and faucet aerators can cut use
dramatically
 WH tank and pipe insulation, low-flow
shower heads, and faucet aerators are
allowed as general heat waste
 Timers on water heater can also be
cost-effective
 Replacements allowable
19 | Weatherization Assistance Program: Overview

Renewable & Bio-based Measures
 Legislative and regulatory change
 Section 206 of EPACT 2005
 Adds renewable energy system definitions
 Defining and evaluating acceptable technologies and systems
for use in weatherization: www.wapsirtt.org
 Direct Final Rule in Federal Register
 Annual Guidance section 5.6
20 | Weatherization Assistance Program: Overview

Client Education
 Client education is a critical
component
 Prolongs life of
measures/equipment
 Conducted before and after
measures are installed
 Instructions on equipment operation
and maintenance
 Tips on energy-saving activities
 Information on carbon monoxide
and other hazards
21 | Weatherization Assistance Program: Overview

A DOE Weatherized Unit is:

A dwelling unit on which a DOE-approved energy audit or
priority list has been applied and weatherization work has
been completed.

As funds allow, the appropriate measures installed on this
unit have an SIR of 1.0 or greater, but also may include any
necessary energy-related health and safety measures.

The use of DOE funds on this unit may include but are not
limited to auditing, testing, measure installation, inspection
and/or administration.
22 | Weatherization Assistance Program
eere.energy.gov
Reporting a DOE Completed Unit

A dwelling unit that meets the definition of a DOE weatherized
unit must be counted as a DOE completed unit.
23 | Weatherization Assistance Program
eere.energy.gov
Post-Work Inspection
 Every home must receive a quality control inspection for
workmanship and appropriateness
 Blower door tests are conducted to ensure proper air sealing
– Identifies any remaining air leaks
– Indicates need for ventilation
 Insulation and other measures checked for quality and
completeness

WAP Results
 Average annual energy savings = $437 per home
 After Weatherization services, typical low-income home saves an
average of 35% on energy consumption
 Returns $1.80 in energy-related benefits per $1 invested
 Returns $2.50 in non-energy benefits per $1 invested
 Avoids 2.65 tons of carbon dioxide emissions for every home
weatherized
 Over 7.0 million households weatherized (both Recovery and
Regular appropriated funds)
 Average reduction in natural gas use – 35%
25 | Weatherization Assistance Program

Outcomes: Quality of Life
 Improves health and safety - reducing carbon monoxide
emissions and eliminating fire hazards
 Lessens the excessive financial burden of families most in
need – reducing the difficult choice between food and fuel
 Helps revitalize neighborhoods and communities across the
country
 Used as catalyst to attract investments from utilities, other
federal agencies, state governments, and private sources
26 | Weatherization Assistance Program

Weatherization Impact
 Reduces the export of local energy dollars and keeps more money
in the community
 Decreases electricity generation and resulting pollution; thus
improving local air quality reducing adverse health effects
 Avoids residential and power-plant emissions of carbon dioxide, a
leading greenhouse gas
