GreenBuildingAdvisor.com is trying to set the record straight on ten common myths about green building. According to Martin Holladay, the top ten are:

1. New York City is an environmental nightmare
2. Walls have to breathe
3. Renovation is less expensive than new construction
4. Spray polyurethane foam creates an air barrier
5. Caulking the exterior of a house reduces air leakage
6. R-value tests only measure conductive heat flow
7. Air conditioned homes don’t need a dehumidifier
8. Efficiency Rating Labels On Appliances Account For All Types of Energy
9. In-floor radiant heating systems save energy
10. Green building helps save the environment

I have to admit – I believed a handful of these myths until I read the article.  Does this mean I have to go around and remove all the caulking I did outside my house?!
