Zero-Energy Homes Are Ready for Mainstream Markets

By Alisa Petersen and Michael Gartman

Zero-energy (ZE) homes—efficient homes that produce or procure as much renewable energy as they consume over the course of a year—are often marketed as luxury homes, only available to the select few that are willing to pay a significant premium to do the right thing for the environment. In keeping with this luxury perception, research shows these homes are often more comfortable and healthier than conventional homes for a variety of…

More "Buzz" from ACEEE Summer Study—Grow Homes

Joe Clark and Martha Wudka of Evergreen Economics did a study in which "getting into the weeds (or weed)" was the whole point. Since marijuana is becoming legal in state after state, they wanted to zero in on the energy use in "grow homes". These are homes where residents grow marijuana for personal use. The biggest energy use gain? Lighting to grow the plants indoors.

Here is the abstract from the paper that was presented at the 2018 ACEEE Summer Study of Energy in Buildings,…

More "Buzz" from ACEEE Summer Study—Builder-Installed Electric Loads

You probably never considered the power consumption of those Ground-Fault Circuit Interrupter outlets (fondly known as GFCIs) in bathrooms, kitchens, and other residential wet spots. But Leo Rainer and his colleagues did and they measured them.  He also measured hard-wired smoke alarms, Arc-Fault Circuit…

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,…

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.
