Residential Indoor Air Quality Study

Project Page

Ventilation is a key component of healthy indoor air quality, with a recent trend toward higher ventilation standards (reflected in the latest version of ASHRAE Standard 62.2). However, cold climate regions face the challenge of achieving healthy IAQ in homes while managing high energy costs.

This project looks at new ventilation standards and recent IAQ research to help inform homebuilders, architects, engineers, and other housing professionals. The project will include a literature review and interviews with experts and will provide recommendations for next steps in IAQ research.
