April 17th, 2018 - Posted by under RESNET News

RESNET and Panasonic has jointly produced a HERS Rater training video, “Measuring Ventilation Airflow – Why and How”.

The 21-minute video’s purpose is to show HERS Raters the most common testing methods for exhaust ventilation airflow.

Austin, Texas homebuilder Matt Risinger is the narrator of the production.  Mr. Risinger begins with an interview with Kristof Irwin, a certified HERS Rater and P.E.  Kristof discusses the health concerns and building science involved with proper ventilation airflow.

The training video then proceeds to certified HERS Rater Sean Harris of Positive Energy. In the training Sean leads through airflow testing using the following equipment:

Alnor Lo Flo Balometer

Energy Conservatory Pressure and Flow Meter V6700

Retrotec DM 32

Energy Conservatory DJ1000

Retrotec Flowfinder

ASHRAE 62.2 Compliance Whole House


The training concludes with Matt Risinger discussing how critical it is that the HERS Rater and builder closely communicate through all steps of the process.
