For decades, ventilation design has been anchored in prescriptive outdoor air requirements. By calculating ventilation rates based on occupancy, floor area, and space type, engineers have relied on a proven, code-compliant framework for delivering acceptable indoor...
The Indoor Air Quality Procedure (IAQP) naturally begins with the mechanical engineer. It is a performance-based ventilation design approach within ASHRAE Standard 62.1, and applying it requires project-specific analysis of contaminants, sources, concentration...
The Hidden Benefits of Designing HVAC Systems with IAQP Ventilation is often viewed as an HVAC decision. In reality, it can become a building-wide decision. The amount of outdoor air a project is designed to deliver influences far more than energy...
There’s been a lot of discussion around ASHRAE 62.1, 241 and what it means for building design. But for many teams, the bigger question is: What’s the difference—and what does it mean for how clean air is delivered in a space? We broke it down in a...
Indoor air quality is becoming a core indicator of how well a building performs. As expectations rise around comfort, energy use, and operational clarity, 2026 will be a year when IAQ is measured more precisely and managed more intelligently. These shifts reflect...
Building codes and ventilation standards set an essential baseline for occupant safety. They define the minimum. But minimums do not guarantee meaningful outcomes, especially when air quality fluctuates throughout the day based on occupancy, outdoor conditions, or...
In every project phase, from concept to commissioning, consultants are tasked with making buildings perform better. But amid the visible improvements in lighting, layout, and finishes, one of the most powerful tools for performance remains unseen: the air. ...
October is recognized as National Indoor Air Quality (IAQ) Awareness Month. For those managing buildings, from HVAC contractors to facility managers, it is a reminder that air quality is no longer a “back-of-house” issue. Clean air should already be the standard, and...
For HVAC and building professionals, indoor air quality (IAQ) has become a mission-critical aspect of environmental control, energy optimization, and occupant health. It is no longer just a wellness add-on. IAQ is now essential for mitigating disease transmission,...
