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...
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...
You’ve likely heard of microplastics in oceans and drinking water, but what about the air you breathe? New research reveals that microplastics aren’t just a waterborne issue. They're also suspended in the air, especially in indoor environments, where we spend up to...
Sustainable Solutions Through Zoned Localized Air Purification: Enhancing HVAC's Green Efforts Sustainability has become a major focus in virtually every industry and the HVAC industry is no exception. As concerns about climate change and resource...
This weekend’s 60 Minutes feature included a story on how indoor air ventilation and filtration systems are “absolutely key” in curbing the spread of viruses, especially with the knowledge we now have post pandemic. Air quality scientists say that from the start of...
In recent years, there has been a heightened awareness among the public regarding air quality and its profound impact on our health. From the COVID-19 pandemic to rising rates of wildfires and pollution, we have come to realize the critical role that air quality plays...
Amid the worst wildfire season in modern Canadian history, thousands of people have evacuated and so far, over 34 million acres have been burnt. With the ability to travel great distances, Canadian wildfires have brought record-breaking pollution to the United States...
