Introducing ASHRAE Standard 241: Elevating Indoor Environments
ASHRAE, a revered authority in building standards, has taken a monumental step by endorsing the publication of ASHRAE Standard 241, a much-awaited standard focusing on mitigating airborne infection risks within buildings. This pioneering achievement sets forth essential guidelines to curtail disease transmission risks linked to infectious aerosols, microscopically small particles carrying disease-causing pathogens. ASHRAE Standard 241 emerges as a comprehensive manual, covering the spectrum of air system design, installation, operation, and maintenance. By adhering to this standard, building owners can significantly diminish exposure to various pathogens, including COVID-19’s SARS-CoV-2 virus and annual influenza viruses.
Key Points of ASHRAE Standard 241 for Airborne Infection Risk Mitigation
Infection Risk Management Mode
ASHRAE Standard 241 introduces the concept of resilience, enabling building owners to effectively counter heightened disease transmission risks. Authorities Having Jurisdiction (AHJs) can mandate the enhanced protections outlined by Standard 241, with flexibility for voluntary implementation during high-risk periods such as flu seasons.
Requirements for Equivalent Clean Airflow Rate
A pioneering move, Standard 241 establishes requirements for an equivalent clean airflow rate. This innovative approach allows for the selection of technologies aligning with economic constraints and energy efficiency goals. These technologies include outdoor air inflow, indoor air filtration, air disinfection methods like germicidal ultraviolet light, and innovative solutions such as Sanalife’s ActivePure Technology, all contributing to effective compliance.
Utilization of Filtration and Air Cleaning Technology
In accordance with Standard 241, Sanalife emphasizes the extensive use of filtration and air-cleaning technologies. These technologies offer an efficient and cost-effective way to meet equivalent clean airflow requirements, surpassing traditional methods such as dilution with outdoor air. Sanalife’s solutions adhere to stringent testing standards, ensuring superior performance and uncompromised indoor air quality.
Planning and Commissioning
Standard 241 encompasses a thorough assessment and planning process, culminating in the development of a building readiness plan. Derived from the ASHRAE Epidemic Task Force, this approach equips professionals with the tools to commission systems and accurately determine their performance post-installation.
Redefining Metrics: The Significance of EOAi in ASHRAE Standard 241
A significant feature of the standard is the replacement of conventional air changes per hour (ACH) with the concept of “equivalent outdoor air for infection control” (EOAi). EOAi measures the flow rate of clean air per person, which, when evenly distributed in their breathing zone, achieves outcomes equivalent to specific removal or inactivation methods on infectious aerosols. The standard also underscores the role of Breathing Zones and Air Flow Direction in optimizing air purifier device performance.
