“Build tight, ventilate right” was first stated in the early 90s; much has happened since then.

This free lecture, updated in July of 2016, addresses the what, why, and how of good ventilation; along with a short history of ups and downs of ventilation rates in the United States. Recent studies have discovered the hazards of some common indoor air pollutants, such as fine particles, Acrolein, and Nitrogen Dioxide, and ways to quantify their negative impact on health. This research has given increased importance to the use of ASHRAE Standard 62.2 in new and existing dwellings. Finally, learn about the major problems found with ventilation systems and what the future holds for ventilation and IAQ.

This is an introductory video lecture to contextualize ASHRAE 62.2 and give you some background to help you decide whether you're interested in going deeper.
