New York State Weatherization Directors Association

Training Center

The NYSWDA Pressure Diagnostics Training House provides our students with an immersive environment and a visual framework on which to build their zonal pressure diagnostics (ZPD) skills. By seeing the relationship between a digital manometer reading and a whole-house display of pressure zones, they learn the skills needed to visualize ZPD in homes they will eventually be auditing. By repeatedly probing various pressure zones with a manometer, then relating their readings with a cut-away of the house they're in, students reinforce their newly learned skills. They can also see in real time how opening a door or turning on an air handler impacts all the various zones.

Add-a-hole, subtract-a-hole, worst case configuration and CAZ testing can all be addressed. With a nearly infinite number of configurations, basic intermediate and advanced ZPD skills can be taught. The interactive touch-screens and classes can be tailored to teach weatherization skills or building science.
