This is a very user friendly training on ZPD and excellent instructions on using the RED ZPD Calculation Tool. Between one and ten, I give this training a ten and will recommend to my fellow Co-Workers.

This is a tool that takes out some of the mystery in air leakage and provides a level of confidence that the best job was done on a project.

by Merredith Plante 03/30/2020

This course was presented as if you already have a basic understanding of zonal pressure diagnostics, very informative! I liked how the video instruction worked with the RED calculations for ZPD and explained what the results of the testing means.
