Whole House Mechanical Ventilation Design and Installation as Though Health Matters

This presentation will cover problems and solutions for residential whole-house mechanical ventilation systems (WHMV). Research has shown that homes intended to have WHMV are often under-ventilated. There will be a focus on design and measurement and verification.


Learning Objectives

Attendees will:
Learn why most homes with mechanical ventilation systems are likely under-ventilated.

Recognize several poor design features that interfere with adequate mechanical ventilation delivery and verification.

Discover three potential locations where measurement and verification of mechanical ventilation airflow rates can be taken.

Recognize the limitations of measuring mechanical ventilation air flow rates.


Speaker Bio

Chuck Withers is a Sr. Research Scientist at The FSEC Energy Research Center where he has been involved in building science research over the past 30 years. During this time he has been involved in energy and indoor air environment studies of hundreds of residential and commercial buildings. Much of this work has focused on impacts of air leakage, unbalanced air, and ventilation. Chuck is particularly interested in energy-efficient methods of whole house mechanical ventilation that maintains comfortable conditions.
