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...
Performance Changes Over Time Commissioning is an important milestone in any indoor air quality strategy. It helps verify that the systems and solutions supporting IAQ are installed properly, operating as intended, and aligned with performance...
How phased IAQ strategies can support existing HVAC systems over time Existing HVAC systems are being asked to support higher expectations around indoor air quality, energy performance, operational visibility, and occupant experience than ever before. But...
Why wildfire smoke is becoming a condition engineers must plan for For decades, HVAC systems have been designed around semi-predictable environmental conditions: seasonal temperatures, humidity levels, and typical outdoor air quality. Wildfire smoke has...
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. ...
