Home Energy Efficiency: How Heat Moves Through Homes
Posted by Matt Beaton on Sat, May 01, 2010 @ 08:12 PM
Today, I found an interesting podcast on, "How Heat Moves Through Homes".
The podcast goes into some decent detail on what, "heat," is and why we insulate. As we've covered previously in another blog post, the podcast also discusses the various ways heat can move (convection, conduction, and radiation).
Dr. John Straube of Building Science Corporation also touches on important points:
- Windows are tough to keep warm
- Energy-efficient buildings need smaller heaters
- Meeting codes doesn't guarantee good performance
- Batt insulation rarely works well in the real world
There is also some good discussion about radiant barriers in the comments at the end of the article (once they clear up who recorded the podcast).
