In our energy newsletter this month, Alden Hathaway argues the importance of putting HVAC ductwork in properly insulated spaces and the impact this has on energy independence. We also give updates on our new titles and links to our latest interviews.

The common practice of placing the HVAC ductwork in the unconditioned space of the attic is a huge and costly mistake for Energy Independence. When one turns on the A/C it must then spend an hour cooling down the super-heated duct before being able to cool the rest of the house.
On our current house in Georgia, we had the entire roof foamed everywhere down to the walls providing a solid 12" foam cap over the house. This means our entire cooling system is operating at the same temperature as the rest of the interior. We have found that the house holds its temperature much better than our Virginia solar house where we added cellulose insulation in that attic after failing to achieve net zero two years in a row. So even now as I write this at 5 PM, the temperature near 100 F outside, the house is still less than 80 F inside before we start cooling for the evening.
What does it cost to insulate the attic? Well, it cost us $2,000 in 2003. However, for a lot less, install a fan vent in the peak of the gable that runs off a small solar panel. This will exhaust the super-heated air and help keep the attic temperature, and, hence, duct work, closer to the ambient outside 95+ F. That's at least half the temperature closer to the inside desired temp. They can be purchased for $200 and will save an additional 20% or so on the A/C bill, most likely paying for itself in one cooling season.
Alden and Tripp Hathaway’s new book Energy Independence: The Individual Pursuit of Energy Freedom is available now! The book presents a plan where the average homeowner can not only achieve Energy Freedom for their household, but usher in the new energy economy. The authors provide a step-by-step recipe for setting up an energy savings reinvestment fund, using low cost and fast energy saving technology returns first to build a fund that eventually moves the homeowner all the way from LED lamps to solar power systems, all with an attractive return on the investment.
