A Day in the Life of Learning

How Can Social Media Change the Future of Energy?

Our articles, editorials, letters, and advertisements provide a kind of window into the evolution of energy conservation technologies, policies, and organizations.

Rob Nicely, Warrior for Sustainability

I was first impressed by Rob Nicely when I heard him speak these words to an audience of builders, designers, and building scientists: "We’re the warriors of sustainability...We already know everything we need to know to build sustainable buildings—the question is, Can we internalize it into our culture and incorporate that learning into our practices?"

Rob is the president of Carmel…

A Furnace that Produces Electricity

Hello all.

It seems that we hear about new technology every day. New energy efficiency products. Many times I have been lead down the path, as I am sure all of you have, that leads to a disappointment.

I am writing this blog - my first one on Home Energy Pros - to inform all of you who really care, that I have been blessed to be able to work alongside someone who has invented a micro-CHP (Combined Heat and Power) that is ground breaking. In short, it's a furnace that produces…

When windows aren't the culprit of a leaky building, solve the mystery with an energy audit.

Liz Vogel replaced the windows and updated the heating system in her small multifamily building in the Logan Square neighborhood of Chicago. But she still noticed that parts of her home were not staying warm in winter. So she set out to solve the mystery of the missing heat. She saw icicles hanging from her roof, and that was a clue that pointed to where heat was escaping. The presence of these “ice dams” meant that Liz was paying to heat her roof and melt the snow instead of heating her…

How an Energy Efficiency Program Killed My Business

Tax Credits Flickr Cut Up Money

Note to Homeowners: This article is primarily aimed at the Home Performance industry. I strive for radical transparency, so I put this in the public sphere for you to read as well.

Energy efficiency rebate programs from gas and electric utilities have become pretty common nationwide. They give rebates for replacing your furnace or adding insulation to your home. While these programs seem like a good idea, they can actually…

Should this Duct Layout be Banned?

When is it ok to put your ducts into an attic, tight up against the Roof Deck?  With more conventional building techniques, I would have to argue: NEVER!  I do not care how the homeonwer pleads to keep their storage space, you cannot count on delivering cool air to the conditioned space with said branch duct.  Even if you did figure out a way to secure the duct to the peak without crushing the inside diameter, the CFM is not the problem.  The real issue becomes the dry bulb temperature of…

After 70 years on the fence, knotty LED light fixtures hide the Ductless in splendor

After the first week, the ductless heat pump and I became so close that could never even think of her as ugly. But some folks don't like the look.

In an analogy to current medical practice, the mini-split heat pump is fabulous but the side effects are minimal for some people. In those cases, we have a cure for the side effect, the LED sandwich light that mesmerizes the eyes softly and makes heat ugly pumps disappear right before your very eyes.…

This year we are excited to have Jeremy Draper, who will tell his unique story of building his first home using as much recycled or re-used materials as possible.  He is nothing short of a Craiglist master.…

No Bubbles, No Troubles!

Or is there? This saying is an old adage in our industry to let the technician know that the refirgerant charge is "all set". You see, there must be a steady stream of liquid to the metering device for it to function properly. For sake of conversation, let's use the TXV. In order for most TXV's to throttle and correctly maintain the desired Superheat, there must be a minimum of 2F of subcooled liquid at the valve (not where it is measured, near the condenser). If the liquid were to flash off… Continue
