Austin weatherized 625 homes for low-income customers in 2021; Austin Energy estimated 687.5 MWh of annual savings after insulation, sealing and AC work

Low-income families feel the sting of bitter winters and blazing summers most. Their homes are often losing heat, their air conditioners are working overtime and their power bills are increasing every year. In Austin, Texas, one utility decided to do something about it. Austin Energy’s Fiscal Year 2021 Customer Energy Solutions Progress Report estimates the Weatherization Assistance Program saved 687.5 megawatt-hours of energy annually in 625 homes and cut peak demand by about 0.55 megawatts.

What really happened in these houses

Weatherization is not some glamorous work. It’s caulking, insulation and duct sealing done right. Crews sealed gaps in walls and attics, added insulation, replaced broken or faulty ductwork, installed solar screens over windows to block summer heat, serviced air conditioners, put in LED light bulbs, and installed carbon monoxide and smoke alarms in homes. In 2021, they added a new item to the list: smart thermostats. None of this cost homeowners a dime. The program covers the full cost for qualifying families, because its goal is comfort and safety, not just lower bills.


Why this kind of program matters so much

Low-income households do not just pay more in absolute terms for energy. They pay a much bigger share of their paycheck for it. The American Council for an Energy-Efficient Economy's household energy burden report highlights that people who are economically disadvantaged pay nearly three times more of their monthly earnings towards energy expenses compared to higher-income households. One reason is that older homes often have poor insulation and inefficient cooling systems. When families must choose between electricity bills and food, insulation and air conditioning are necessities, not luxuries.

Removing the paperwork that kept people out

Good intentions won't help if people can't get into the program. Austin Energy took note and rebuilt the entire application process. It has been transformed into a one-page form that works on a phone, is available in English and Spanish and takes only minutes to complete. The utility also began accepting remote and virtual inspections, allowing the program to safely continue during the pandemic. That change helped drive a 700 percent increase in applications. That surge reflected rising demand meeting the program's improved accessibility; like many capacity-limited assistance programs, Austin Energy's weatherization work has historically carried unmet applications over into future fiscal years' budgets rather than completing every request within the same cycle, so a sharp rise in applications and a fixed number of homes completed in one year aren't at odds.

Eligibility requirements also saw some change. The income threshold was increased from 200 percent of the federal poverty level to 80 percent of the median family income within the community, thereby increasing the threshold for a family of four from $53,000 to $78,100. In one stroke, this requirement made way for thousands of families that had been struggling but fell just outside the previous threshold criteria. Moreover, to increase the efficiency of the process, Austin Energy relied on census records, tax appraisals, and its billing information to automatically pre-qualify several applicants, cutting down on the paperwork families once had to hunt for. This utility company also partnered with Basta Austin, a tenant's rights non-profit organization, in order to provide weatherization assistance to renters at the North Lamar Mobile Home Park, a community that often falls outside the reach of standard efficiency programs.

What the savings actually mean

When you divide the total across all 625 properties, that works out to just over one megawatt-hour of energy saved per home each year. As a result, participating homes should use less electricity for heating and cooling, lowering utility bills and making the homes more comfortable. Austin Energy’s own figures estimate the total costs of rebates, operations, and outreach associated with the 2021 weatherization campaign at around $3.5 million, spent on households that otherwise couldn’t have afforded these upgrades on their own.

The bigger picture: Weatherization pays off nationally

Austin’s results fit a pattern seen around the country. A national evaluation summarized in the Oak Ridge National Laboratory “Weatherization Works II” report found that the Weatherization Assistance Program of the U.S. Department of Energy successfully reduces energy consumption and utility costs in low-income housing, as well as improving the health and safety of such homes. The findings from Austin support the above narrative of a long-standing federal program that continues to make a difference on the local level.

Looking ahead

Austin Energy did not stop there. As of the Fiscal Year 2021 report, Austin Energy's plans for fiscal year 2022 included a pilot program where the project would provide HVAC repairs and installations to clients on the city's Medically Vulnerable Registry, along with a plan to return to face-to-face final inspections as part of quality control measures. For a city experiencing increased living expenses and harsher weather, individual home weatherization can look like a small move. However, for 625 families who received new insulation, sealed ducts, and a working AC unit in 2021, it probably made a real difference in their monthly budgets and their day-to-day comfort.
