In building science, a lot of what we measure is invisible. And much of it is related to pressure and flow. Most of us do blower door or duct leakage testing or both, but there are many other important things we can be measuring using our manometers that can help us figure out what is going on in a home. This session will give you an introduction into measuring draft, CAZ depressurization, room pressures, zone pressure diagnostics, pressure pans, static pressures on an air handler and tools for long term data logging of pressures.

 

Learning Objectives:

• Describe the data needed for the Zone Pressure Diagnostics add a hole method
• Identify the advantage of diagnosing duct leakage with a pressure pan
• Explain how measuring air handler static pressure can help diagnose problems with the system
