1 | Weatherization Assistance Program: Overvieweere.energy.gov  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

2 | Weatherization Assistance Program: Overvieweere.energy.gov  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.)

3 | Weatherization Assistance Program: Overvieweere.energy.gov  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.)

5 | Weatherization Assistance Program: Overvieweere.energy.gov  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?

6 | Weatherization Assistance Program: Overvieweere.energy.gov  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

7 | Weatherization Assistance Program: Overvieweere.energy.gov  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

8 | Weatherization Assistance Program: Overvieweere.energy.gov  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

9 | Weatherization Assistance Program: Overvieweere.energy.gov  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

10 | Weatherization Assistance Program: Overvieweere.energy.gov  Illustrates heat loss  Guides air sealing and insulation  Helps to educate clients  Quality control for insulation and other measures Infrared Camera

11 | Weatherization Assistance Program: Overvieweere.energy.gov  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

12 | Weatherization Assistance Program: Overvieweere.energy.gov  Leaky ducts can increase costs by 10-30%  While blower door runs, pressure pan placed over air register Pressure Pan

13 | Weatherization Assistance Program: Overvieweere.energy.gov  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 systemsManometer

14 | Weatherization Assistance Program: Overvieweere.energy.gov  Blown insulation most effective –Holes discreetly cut in walls or ceiling –Insulation is blown into space through a tubeInsulation

15 | Weatherization Assistance Program: Overvieweere.energy.gov  Reduces air infiltration and heat loss –Dense-pack insulation often installed before air sealing, since it reduces leaks so effectivelyInsulation

16 | Weatherization Assistance Program: Overvieweere.energy.gov  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

17 | Weatherization Assistance Program: Overvieweere.energy.gov  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 fixturesLighting

18 | Weatherization Assistance Program: Overvieweere.energy.govRefrigerators  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

19 | Weatherization Assistance Program: Overvieweere.energy.gov  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

20 | Weatherization Assistance Program: Overvieweere.energy.gov  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:  Direct Final Rule in Federal Register  Annual Guidance section 5.6 Renewable & Bio-based Measures

21 | Weatherization Assistance Program: Overvieweere.energy.gov  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

22 | Weatherization Assistance Programeere.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:

23 | Weatherization Assistance Programeere.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.

24 | Weatherization Assistance Programeere.energy.gov  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

25 | Weatherization Assistance Programeere.energy.gov  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

26 | Weatherization Assistance Programeere.energy.gov  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

27 | Weatherization Assistance Programeere.energy.gov  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 Weatherization Impact
