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, measurement and verification.

Learning Objectives:
- 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.
