Hands-on Refrigerant Charge Measurement @ Johnstone Supply - Fresno
Apr 13 @ 8:00 am – 12:00 pm

Class Overview: 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.

Building Energy Science I – Preparation for Building Sealing @ Johnstone Supply - Fresno
Apr 13 @ 1:00 pm – 5:00 pm

Class Overview:

This is a full day class. As more and more attention is given to Air Sealing of Homes in California what basics should everyone who is part of the audit team to the Air sealing team know as they prepare to seal Homes. The course deals with basic Air and moisture flow. The purpose is to assist prevention of homes that develop avoidable problems with some planning , understanding of moisture, pressure and heat flow dynamics. This is recommended for each HERS Rater, Mechanical Contractor or Building official involved in an Air Sealing Project.

Building Pressure Diagnostics @ SDG&E Energy Innovation Center, San Diego
Apr 19 @ 8:00 am – 12:00 pm

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.
