The Mixed-Up IAQ and Infiltration Limit Blues
Allison Bailes of Decatur, Georgia, is a speaker, writer, energy consultant, RESNET-certified trainer, and the author of the Energy Vanguard Blog. You can follow him on Twitter at @EnergyVanguard. Last week, I caught the second day of Building Science Corporation’s Experts’ Session. (Click the link to download the presentations from the BSC website.) Joe Lstiburek spoke the whole day about ventilation, and I’ll be writing an article about that soon. At the end of that day, though, we got a little surprise.Eric Werling got up and gave a short presentation, making some recommendations on reconciling the differences between Joe and the ASHRAE 62.2 committee (more on that later as well, after I get a copy of his presentation). He also performed a great little song about the ventilation wars. Here it is, with the lyrics below.Enjoy!
