WAP Rules and Regulations

Weatherization Assistance Program

2012 NASCSP Weatherization Training

Additional Background Reading Materials


First Generation (1975 to 1979)– Response to oil embargo in early 1970’s– Started in Maine– Originally administered by CSA– Used volunteer labor– Installed only low-cost measures– Little or no reporting and accountability

WAP History


Second Generation (1979 to 1986)– Used volunteer labor under CETA– Installed temporary measures (plastic storm windows, caulk,

door stripping, attic insulation)– Little or no diagnostics– Project Retro-tech as audit tool– Addressed building envelope with heating priority

WAP History (cont.)


Third Generation (1987 to 1996)– Used professional labor– Addressed both building envelope and mechanical heating

systems– Some diagnostics used– Computerization of audits and other operations– State and national evaluations– Structured training and technical assistance

WAP History (cont.)


Fourth Generation (1996 to present)– Highly trained crews– Permanent, cost effective measures (audit test)– Rental and health and safety plans– Advanced diagnostic tools in use– Addresses all climates – cooling and heating – Leverage activities at several levels– Coordination with housing programs– Comprehensive national evaluation

WAP History (cont.)


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

What is Weatherization?


Energy audits conducted

Air infiltration reduction using blower doors

Attic and floor insulation

Dense-pack wall insulation

Duct sealing

Domestic hot water heater improvements

Furnace service

Furnace replacements

New refrigerators

Duct system balance and sealing

Energy efficient lighting retrofits (CFL)

Incidental repairs

And more………..

Types of WAP Services


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

Heating System


Technicians can tune-up or repair cooling systems

Ducts may require sealing and/or balancing

May add fans, ventilation for health and safety

Cooling System


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

Air Sealing


Illustrates heat loss

Guides air sealing and insulation

Helps to educate clients

Quality control for insulation and other measures

Infrared Camera


Duct system may need sealing and/or balancing

Duct tape should NOT be used – Apply Mastic

Ducts in unconditioned spaces should also be insulated

Duct Sealing


Leaky ducts can increase costs by 10-30%

While blower door runs, pressure pan placed over air register

Pressure Pan


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

Manometer


Blown insulation most effective– Holes discreetly cut in walls or ceiling– Insulation is blown into space through a tube

Insulation


Reduces air infiltration and heat loss– Dense-pack insulation often installed before air sealing,

since it reduces leaks so effectively

Insulation


Converting incandescent lighting to fluorescent

Replacing refrigerators

Replacing or insulating water heaters

Reducing hot water use

Reducing appliance usage through client education

Electric Base Load Measures


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

Lighting


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


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

Water Heater


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

Renewable & Bio-based Measures


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

Client Education

23 | Weatherization Assistance Program eere.energy.gov

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.

A DOE Weatherized Unit is:


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.


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

Post-Work Inspection


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%

WAP Results


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

Outcomes: Quality of Life


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
