New Whitepaper Highlights Path to IAQ Compliance
As indoor air quality standards evolve in response to growing contaminant concerns, many buildings and facilities teams may be unprepared to meet changes in regulations. A new whitepaper from Fellowes highlights a critical gap between current ventilation standards and emerging requirements for infection control, while outlining a path to compliance that prioritizes cost savings, contaminant control and occupant health.
The whitepaper, “Achieving ASHRAE 62.1 and 241 Compliance: How In-Room Air Cleaners Complement HVAC Systems,” examines how the introduction of ASHRAE Standard 241 is reshaping how buildings approach indoor air system designs.
While ASHRAE 62.1 has long served as the foundation for acceptable IAQ through adequate ventilation rates, ASHRAE 241 introduces higher clean air requirements focused on reducing the spread of airborne infectious aerosols. The result is a growing divide between what buildings are designed to deliver with their HVAC systems, and what emerging standards require.
Key findings in the report include:
- Clean air requirements under ASHRAE 241 can be four to six times higher than those in ASHRAE 62.1, creating a compliance challenge for engineers and facility managers.
- Traditional ventilation-based approaches, including Ventilation Rate Procedure, rely on increasing outdoor air intake and may be costly, energy-intensive and difficult to scale with existing infrastructure. It often requires significant HVAC upgrades, ductwork modifications and increased energy consumption to condition additional outdoor air.
- Performance-based strategies, such as the Indoor Air Quality Procedure, can reduce reliance on increased outdoor air to optimize energy use while meeting evolving IAQ standards.
- In real-world applications, such as classrooms and offices, existing HVAC systems often fall hundreds of CFM short of ASHRAE 241 targets, requiring supplemental solutions to close the gap.
