Reducing energy use for heating hot water remains a major challenge around the world. This paper describes a novel solar photovoltaic assisted heat pump water heater (PV-HPWH) which achieved an 83% reduction (COP 5.4) in water heating energy compared with electric resistance. This technology demonstrates…

I am always impressed with the work of Susan Shelton and the Shelton Group. So an email message with the subject line from her office, “Age, religion & environmental messaging: what works?” immediately caught my attention.
In an Eco Pulse special report, “United We Understand,” the Shelton Group digs into their research on how best to reach an audience about environmental concerns. An associate of Shelton, Lea Ann Head,…Continue

This year’s hurricane season is the most expensive on record, with $202.6 billion in damages according to Bloomberg. These storms across the Atlantic had devastating impacts on people’s lives and homes, on communities, and on infrastructure in the hardest-hit areas.
In fact, the damage…Continue

“Why do you need to cool and heat the whole building? Why don’t you cool and heat individual people?” asked Yi Cui, professor of materials science and engineering at Stanford University.
Putting on or taking off articles of clothing works to keep a body cool or warm within a certain temperature range; outside that range we rely on heating systems and A/C to keep us comfortable. But what if one garment did both the heating and the cooling?
Cui’s colleague and postdoctoral fellow…Continue

Connecticut’s 2016 Zero Energy Challenge reinforces the growing interest in the zero-energy home building movement. In addition to increased participation among experienced homebuilders, the 2016 challenge had an influx of inexperienced zero-energy home builders trying their hand at zero-energy homebuilding for the first time, with two winning.
How did they do it?
Research, research, and more research
There has been a lot of interest of late in the weatherization and broader home performance community in putting a value on the health benefits of weatherization. We’ve come a long way in the last several years and have reached, I think, some strong consensus that the health benefits of weatherization and home performance retrofits are real and valuable. This means that making healthy housing a part of your business plan makes good sense.
E4TheFuture is a nonprofit organization…Continue
Sometimes it feels like Home Energy and the DOE Weatherization Assistance Program (WAP) grew up together, along with what was formerly known as ACI and is now the Home Performance Coalition (HPC) and some other energy efficiency advocates. The WAP program is celebrating four decades of air sealing, insulating, health home making and family supporting on National Weatherization Day on Sunday, October 30th.
That would make Home Energy WAP’s little brother or sister. We…Continue

That’s the National Association for State Community Services Programs, which held it’s annual training conference September 16-18 in Sacramento. NASCSP serves the DOE WAP program, as well as other low-income programs through training and advocacy in Washington D.C.
I’ve been to several of these conferences over the 15 years I have worked at Home Energy. There are always changes, but this year I noticed a big change. A lot of the leadership that shepherded WAP through the ARRA…Continue
The poet Muriel Rukeyser once said something like this: The Universe is not made of atoms; it’s made of stories. I think that conferences are made of stories too, like the one I’m at this week, the National Energy and Utility…
When I received an email from Larry Zarker of BPI, informing me that I had been inducted into the BPI Building Performance Hall of Fame, I thought it must be a big mistake. Then I looked at the list of previous inductees and was sure it was a mistake! I haven’t even done a blower door test all by…Continue

As usual, the ACI National Home Performance Conference contained too many highlights to mention in one blog post. So I will share just a few.

I'll be flying out to Detroit for the ACI National Home Performance Conference next Monday, but before get to Detroit and that great conference, I thought I'd share one more special moment from Energy Out West.
