One of the great benefits of going out into the field to do quality assurance and training for HERS raters is that I get to see what's going on in new construction. Last week I visited HERS raters in Nashville, Memphis, and Birmingham and got to see that there's some good stuff happening in the...

On my thousand-mile quality assurance road trip last week, I visited a house that was designed to produce more energy than it uses, making it a net zero energy home. You can take any house all the way to net zero just by giving it enough on-site power production (photovoltaics, wind, hydropower...

For about the same price as you'd pay for an iPad, you can buy a home energy audit to give to a loved one this holiday season. Yes, the iPad is sexier. Yes, the iPad is more fun. Yes, everyone wants an iPad. (Even one of my most anti-Apple friends has one.)
