Home Energy Audit Finds Potential Savings For Homeowner

Evening Edition

Above: KPBS Reporter Ed Joyce looks at how home energy auditing can help homeowners. But at what cost?

Aired 10/4/11 on KPBS News.

A San Diego homeowner wanted to reduce her increasing utility bills. After a home energy audit, she was surprised how much energy her home loses and how much it would cost to change it.

Erin Cooley lives in a modest home near Del Cerro, but her bills for gas and electricity have been rising.

"With the kinds of bills we get from SDG&E, we are looking to save as much as possible," said Cooley. "I know we have done some things - change light bulbs, install new windows, new roof. But I think there are a few other things we can do to help the bills go down a bit."

Her bill averages about $170 a month, but can be higher depending on the time of year.

She opted for a home energy audit with San Diego home performance contractor Christian Asdal of GGR Energy to find out how much energy was being wasted at her 2,200 square foot home.

Asdal begins the home energy assessment with an interview.

"We really want to make sure that we understand their experience in the home, why they may have called us, if it's a comfort issue, or if it's a safety issue or an energy efficiency issue," said Asdal. "We want to know what they're feeling, how the home works for them so that can help us better diagnose what we're looking for and have some places to start."

Asdal told Cooley she can save money by switching to a gas stove.

"And it's going to cost you less to run that appliance," he said.

"And do you think that's going to be true going forward?" asked Cooley.

"I think so," said Asdal.

When the interview's over, Asdal and his assistant start the audit with an inspection of the outside and inside of the house.

From there, they do a variety of tests using specialized tools to measure energy loss from doors, windows and vents. The audit also evaluates the efficiency of appliances, water heaters and other energy sources.

Asdal said Cooley's gas-operated pool pump outside, and her furnace inside, are energy suckers.

"A lot of this stuff here is old," said Asdal. "You can hear the pilot light running which just means it's constantly drawing energy, like the one outside, which is going to contribute to her therm load."

He said the tests establish a baseline to show the homeowner how improvements would benefit the bottom line: energy savings and lower utility bills.

But the homeowner has to spend money to make those changes and hope the savings on the monthly bills makes it worth the expense.

"We address the payback, we look at what the return on investment is and we make sure that she is aware of all the energy saving rebates that are available," said Asdal.

Several weeks later, we rejoined Cooley in her living room to look at the comprehensive energy report.

But when she looked at the cost of the recommended changes and upgrades, Cooley decided it was too much investment for too little savings.

"For us, the numbers don't seem spectacular," Cooley said. "Any savings is good but when you have to crunch numbers and do the math about what you're going to lay out of your pocket and what return you're going to get, we were surprised. I think we expected more."

For example, Cooley said if she paid for air sealing, new attic insulation and duct replacement, her energy savings would be 21 percent.

"Now only for us it doesn't seem like a lot, 21 percent, that's $300 per year when the cost of doing that is about $5200 and that includes a rebate," said Cooley.

Cooley said the cost for adding solar didn't pencil out either.

"This is only two people in a relatively large home, if it were a family that had a higher energy bill, some of this investment might make sense," she said.

Cooley said the energy audit report shows old appliances account for more than half of her monthly energy costs.

She said spending money now, during a time of economic uncertainty, is something she has to think about.

But, she does plan to consider upgrading some appliances and adding the attic insulation, giving her a little bang - or slightly lower bills - for fewer bucks.

For those who get a pencil and try to figure the payback, they need to pencil in something else, the value upon resale. (studies have shown increased value) That $5k she invests now could be worth $10k in increased revenue (i.e. value) when your home finally goes on the market, for your kids or grandkids or even you. That's a better return than the market pays or interest pays in the bank.And the $300 in savings today could be a savings of double that after increases to our energy bills year after year. Have you visited http://www.sdreduceproduce.org ? That special program is good until Oct 20, so worth checking for two minutes. They are able to answer your questions in person, and not try to sell you anything, either. Best of both worlds.
Last question, do you expect a payback on your vehicle?

I found myself yelling at the radio when I heard this story. Why isn't he telling her about the other benefits of upgrading her house. Why doesn't he put a price on the reduced attic filth winding up on her dinner plate as a result of that attic floor and duct air sealing. Why not put $5 per day on reducing the amount of fiberglass, rat poop, hanta virus from rodent urine, and all the other nasties that live in her ductwork and attic. And then there's the comfort--like that commercial says--a comfortable home that does not get hot or cold: PRICELESS. The report makes a great case for the fact that fossil-based energy is too cheap. And it reinforces the misconception that this prudent homeowner will become the laughing stock of her neighborhood if she does not pencil out her investment. But the real news should be: hey, we have this problem. It's called poorly performing, unhealthy houses. We have a skilled workforce ready to fix them. These are the green jobs politicians are constantly saying we'll create. Well how are we to create them when uneducated reporters only tell part of the story.... And by the way, what's the payback on that swimming pool?

Why doesn't a home upgrade pencil out? That's a really good question. Because gas and oil are really cheap to burn. Because we don't pay for the price of pollution, we don't pay for the price of asthma, we don't pay for the price of climate change. It's disappointing that the true price was not addressed in this report. It's disappointing that one of the few things a homeowner can do to reduce their carbon footprint was portrayed as a poor use of hard-earned money. I realize 3 minutes is short, but there are multiple benefits to a home audit and home upgrade that were not mentioned. 1) more comfortable home: with better insulation and sealed ducts, there is less need for blowing heaters and drafty air conditioners 2) cleaner, fresher air because you're no longer ventilating with dirty air from the attic. Home performance is a new field that's poorly understood. I hope KPBS will follow up on this report, so listeners can become better educated on the topic.

Home Energy Audits are a great tool for home owners. As the article mentions, upgrading older homes can really get expensive and not provide much return, but the long term benefits reach far beyond the wallet.

A typical single family home contributes to 11.55 metric tons of CO2 emissions per YEAR. Reducing your homes energy usage just 25% is the equivalent of taking (1) car off the road per year or planting 2.3 ACRES of mature forests per YEAR!

I think its time for everyone to get a Home Energy Audit today, since we will never plant enough forests to offset our carbon emissions. Do you part TODAY and get a Home Energy Audit from TreeFrog Builders!
