ASHRAE 241 Compliance Services for Healthcare Facilities
Control of Infectious Aerosols Through Targeted Assessment, Planning, and Performance Validation
As healthcare environments evolve to meet new standards in infection control, VERTEX is your trusted partner in achieving compliance with ASHRAE Standard 241 – Control of Infectious Aerosols. Our multidisciplinary experts help healthcare facilities proactively reduce exposure to airborne infectious particles through comprehensive evaluation, planning, validation, and training services.
ASHRAE 241 introduces a performance-based approach to ventilation and filtration, shifting focus from prescriptive air changes to Equivalent Clean Airflow (ECA) and mitigation of pathogen-laden aerosols. With deep expertise in environmental health, industrial hygiene, and healthcare facility operations, VERTEX equips you with tools to comply confidently and effectively.
Our ASHRAE 241 Services
Infectious Aerosol Risk Assessment
We begin with a facility-specific risk assessment to identify critical spaces—including operating rooms, isolation rooms, waiting areas, and high-traffic zones—where the risk of airborne transmission is highest. This informs all subsequent compliance and performance strategies.
Building Readiness & Compliance Planning
Our consultants work closely with your facility team to develop a tailored ASHRAE 241 Building Readiness Plan. We help integrate infection control measures into operational and capital planning, minimizing disruption while maximizing compliance value.
Equivalent Clean Airflow (ECA) Calculation
We assess your current ventilation performance using the ASHRAE 241 methodology for EAE, considering clean air delivery, aerosol persistence, and occupancy profiles. This critical metric replaces traditional ACH (air changes per hour) for evaluating infection mitigation.
ECA Validation & Performance Testing
Using advanced testing methods — including DNA-tagged surrogate aerosols and tracer particle analysis — we validate your facility’s EAE in real-world conditions. This provides quantifiable performance data aligned with ASHRAE 241 expectations.
Supplemental Air Cleaner Selection & Testing
Where central HVAC cannot meet ECA targets, we recommend and validate the placement of supplemental air cleaning technologies, such as portable HEPA units or UVC systems. We test their effectiveness in situ, ensuring measurable improvements in clean air delivery rates.
Routine Testing & Maintenance Support
To maintain long-term compliance and performance, we provide ongoing verification, maintenance protocols, and documentation support. Our testing services align with both regulatory and accreditation requirements.
Staff Training & Education
ASHRAE 241 compliance is a team effort. We offer tailored training programs for clinical and facility staff to understand ventilation goals, identify system warning signs, and support day-to-day infection control through awareness and operational practices.
