The House of Pressure visually demonstrates pressure and air flow dynamics
within a residence, using pressure diagnostics. It is a model of a single-family home,
made of a clear, high-strength plastic laminate called Lexan that can be
written on with a dry-erase marker. The interior of the House can be viewed
from all four sides. It gives the instructor the ability to create and control
air flow with working scale reproductions of the mechanical air distribution
systems that are found in most homes.


The House features an operable forced air duct system,
a clothes dryer, a bathroom fan, a fireplace, and a water heater. There are
smoke generators in the water heater and the fireplace to demonstrate the
dangers of backdrafting; and a smoke generator in an exhaust pipe in the garage
to show the danger of CO infiltration from a garage into conditioned space.
(The menacing theme of Jaws plays when backdrafting occurs, as a warning that
smoke is coming back into the House!)

I was fortunate enough to have had some training with Anthony Cox's House of Pressure and it is very good as a visual tool in understanding pressures and how one area of a home can be affected by what is going on in other areas. He also has an attic access hatch that is neither sealed or insulated. Really good effects used. However, it is very, very expensive.

It would be nice to see groups of HP Contractors  who are in the same region "going in" one of these,

or better yet,  having a utility or other public organization  own one accessible to all, similar to the tool-lending library model.
