ASHRAE Infection Control Committees bring together technical experts across multiple disciplines to advance research, standards, and guidance related to indoor air quality and the mitigation of airborne infectious diseases. These committees support the development and maintenance of key ASHRAE standards and guidelines, including ventilation, filtration, air cleaning technologies, and HVAC system design strategies for health-focused building performance. Their work informs best practices for reducing pathogen transmission risk in healthcare, commercial, and institutional environments through evidence-based engineering solutions and cross-sector collaboration.
