Some "Buzz" from ACEEE Summer Study! PV Marries Heat Pump, by Danny Parker, Florida Solar Energy Center



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…

Using God Talk—or Not—to Help the Planet?

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,…

Rebuilding After a Hurricane, and the Next, and the Next...

 

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…

Cool—and Warm—Clothing

“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…

A Healthy Home and a Healthy Bottom Line

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…

Forty Years of WAP—A Family Celebration

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…

The NASCSP Landscape

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…

Unexpected Blessing

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…
