ASHRAE 62.1-2025 sets minimum ventilation rates and design requirements to ensure acceptable indoor air quality (IAQ) in buildings, preventing health issues by controlling contaminants like CO2, odors, and pathogens. It is a critical tool used by engineers, building code authorities, and designers to design, operate, and verify ventilation systems for commercial and institutional buildings, often through prescriptive or performance-based methods.
The 2025 edition refines humidity control, adds emergency ventilation, and improves calculation methods for better IAQ and energy efficiency.
