Seminar 39 -- LIVESTREAM: How to Evaluate Mechanical Ventilation in Existing Buildings

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

Ventilation is necessary for maintaining acceptable indoor air quality and minimizing adverse health effects in the built environment. Ventilation can also be used as an engineering control to reduce occupant exposure to airborne infectious aerosols. How much ventilation does a building need, and how do owners, operators, and occupants know if it is provided? This session will cover the fundamentals of indoor air quality and important metrics for evaluating ventilation system operation; tools and strategies, from CO2 meters to tenant Q&As, that can be used by engineers and occupants; and field validation methods for engineering controls in a healthcare facility.
