Program Overview

Airflow measurements are critical to achieving great home performance; from the aspects of comfort, health (IAQ) and energy usage.

As houses tighten, energy codes require mechanical ventilation. To get the performance right it is important to measure the ventilation system airflow.

Join us as Bill Spohn leads us through a review of residential ventilation airflow measurements, how they work, and how easy they are to do.

About the Maine Indoor Air Quality Council

This webinar is free of charge.  Please do consider, however, making a donation of any size to support the work of the Maine Indoor Air Quality Council.

More about us:  There are many pollutants indoors that can make people sick: mold and moisture, radon, asbestos, lead, PCBs, carbon monoxide, volatile organic compounds, as well as contaminants in private well water.  Because U.S. citizens spend an average of 90% of their time indoors, there is significant cause for concern for the health and safety of our population.  In fact, the U.S. Environmental Protection Agency indicates that the #1 environmental health threat in the U.S. today is indoor air pollution.

The Maine Indoor Air Quality Council (MIAQC) is an independent nonprofit organization dedicated to creating healthy, environmentally-sustainable indoor environments through education, communications, and advocacy. The Council is the #1 educator in Maine of professionals of all types on practical strategies to design, construct, operate, maintain, investigate, and remediate buildings. We educate members of the public on strategies to improve the IAQ in their own homes. And we advocate in the public arena for a policy infrastructure that supports healthy IAQ for all buildings types, including homes, workplaces, and schools. We also raise funds to pay for fixing radon problems in low-income Maine homes.  

Donations will help sustain our work for the coming year.  What will that include?  Advocating for healthy indoor air quality provisions in the Maine building code and in energy efficiency and climate change initiatives occurring in-state. Pursuing policy goals around radon. Creating new relationships with residential construction groups so we can bring residential contractors the training they need to create healthy, energy-efficient homes. Mitigating radon in low-income Maine homes. Working with commercial designers and contractors on strategies to improve indoor air quality in large buildings. And serving as a resource for members of the public who struggle with the indoor air quality in their own homes.
