Class Schedule

Class Overview:

The House Pressure Diagnostics class explains the principles of air pressure within a building and how to use these principles to diagnose airflow problems. Understanding the principles of airflow within a building can help a HERS Rater locate the largest infiltration leaks and help determine the air leaks that should be addressed first. The training class also demonstrated how to conduct a “duct leakage to outside” test and provides participants the opportunity to perform the test during class.

Reducing air leakage is an important part of nearly all existing home energy improvement programs. And the most important part of understanding and using house pressure diagnostics is that by reducing infiltration cost effectively it helps homeowners achieve energy and cost savings and improves comfort for the homeowner.

A residential split system air conditioner undergoes its final assembly at the time of installation. An important factor is the amount of refrigerant in the system (commonly referred to as proper charging). Air conditioner energy efficiency suffers if the refrigerant charge is either too low or too high. This training is designed to assist HERS Raters and HVAC technicians to properly perform a Refrigerant Charge verification. This is a Hands-on class with operational equipment. Please feel free to bring your verification equipment.

Class Overview: This training session covers issues and cautions that anyone involved in air sealing needs to consider when tightening a residential structure. It builds upon the principles in Building Energy Science Basics 100. A checklist of inspection points is provided as part of the training.
