A true professional energy audit will give a homeowner so much more than just the basic air leakage data that so many tend to focus on. One of the most important aspects that can be discovered is the number of air exchanges that are or amount of fresh air that is being brought into a home. It is possible to have a home that is too tight. A home with inadequate ventilation will have moisture problems, be less comfortable, and may have unhealthy levels of a number of different pollutants. Even more frightening, a home that is too tight may cause combustion appliances to backdraft pollutants, including deadly carbon monoxide, into the living space. A professional energy auditor will be able to give you pointers on improving your energy efficiency and using your energy upgrade money in the most efficient manner. They can also help you keep your family safe. Here is a video from the DOE on what to expect in a complete energy audit (also sometimes called a green home inspection). http://www.greenhomesconsultant.com/green-home-inspection.html David Arthur, LEED-AP, BPI Building Analyst, AEE Certified Energy Auditor

We had a blower door test done on our 100 yo farmhouse here in the Ozarks. The biggest revelation was the huge amount of infiltration around the doorway frame and casing on the interior walls. Old houses are framed with wall studs that go from the foundation all the way to the roof (balloon framing) and there is nothing to stop the unconditioned crawl-space/attic air from blowing right in - or the conditioned air from blowing out. I knew that, but for whatever reason just didn't consider how big a factor it was.
