New ASHRAE Standard Targets Reducing Risk Of Airborne Infectious Aerosol Transmission In Buildings

ASHRAE recently published “Standard 241, Control of Infectious Aerosols,” which establishes minimum requirements for controlling infectious aerosols and reducing the risk of disease transmission in new and existing buildings.

The new tool addresses both outdoor air system and air cleaning system design, installation, commissioning, operation, and maintenance to reduce exposure to infectious aerosols.

Among the topics in the new standard are an infection risk management mode, requirements for equivalent clear airflow rate, filtration use and air cleaning technology, and assessment and planning strategies including a building readiness plan that documents procedures for assessing systems to determine if they’re working properly.

“Standard 241 represents a significant step forward in prioritizing indoor air quality,” said ASHRAE President Farooq Mehboob in a press release.
