Angry Air!

John Tooley said, “Air is like crooked rivers, crooked people, teenagers, and cheap labor.  It always seeks the path of least resistance.”  He didn’t say that Angry air is Noisy air.   Air doesn’t like being forced through corrugated, flexible ducting, pushed around corners, and made to force open dampers.  It resists being made to perform in a way that it doesn’t want to.  It takes more and more force as the resistance increases.  Air is just fine when you just let it move at will.  It can…

Zonal Pressure Puzzle

I have a wonderful little (16 x 14 x 8) test cabin at Bristol Community College in Fall River, MA.  There are 3 'rooms', one of which stands in as the bathroom.  It has a bath fan in the ceiling and a small, hopper window.  When I depressurize the house to 50 Pascals, the pressure between the bathroom and the main body of the cabin is just 4.3 Pascals.  When I stand in the bathroom with the door closed, air is pouring in through the bathroom fan, there is enough flow to make the fan rotate…

Shades of Gray in Residential Construction Morality

I was called in to perform a last minute duct test for a modular home builder.  He was all in a dither to have a duct test and a blower door test done on a Friday so that he could get his Certificate of Occupancy (CO) so the homeowner could move in the following Monday.  He said that he’d just found out that he needed these tests.  The building inspector asked for them at the last minute!

I was glad to do it partially because it’s good to have builders aware of what is going on…

150 Years to 10

Houses should last a very long time.  The Knap of Howar was built approximately fifty-five hundred years ago.  Pueblos in New Mexico were built over a thousand years ago.  Saltford Manor House, in Somerset, England was built sometime in the twelfth century and is still occupied!  These houses are built of extremely durable materials like stone or adobe.  But even the wooden houses…

Rocket Science?

The old expression when something is supposed to be simple is to say that, “This is not rocket science!” as though rocket science was the most complicated thing we can think of.  I will admit that some of the things rocket scientists have done are pretty amazing.  I don’t have a clue how you land a probe on an asteroid moving at thousands of miles an hour somewhere out there in space.  Or manipulate a vehicle on the surface of a planet and send back, “Wish you were here!” snapshots - in…
