Leaving the Door Open – I Cry Fowl!


GHAOne of our top advisors a few years back had a unique experience on an assessment visit.  Leaving the doors open to his vehicle, he unknowingly acquired some unwanted guests.  It made me think about our homes and another unwanted “guest”: uncontrolled airflow via attics and elsewhere in the home.  (A great resource if you haven’t seen it already can be found in our learning center)

When we test airflow in homes we use cubic feet per minute as a unit of measurement.  Ideally this can help people visualize how much air moves through your walls ceilings and floors.  The large fan we place in the doorway of the home measures this flow and allows us to compare the amount of leakage in your home to others of similar size. Many of us don’t often think in terms of cubic feet, but you know, I’d guess it’s about the same as a good sized chicken.

You would be surprised by the amount of leakage in the average home when you can’t see the holes.  They are hidden behind walls and floors, connections in the ceiling.  In places we don’t really think about.  Every chicken’s worth of air that moves uncontrolled in or out of your home costs, not only in terms of money, but also comfort.  There could be GHAhundreds of them entering or leaving your house every hour.  Not sealing those leaks is like leaving the door open all year long.

Keep the chickens where they belong.  Close the doors.
