Post-Pandemic Ventilation: Is Your Office Building “Healthy” or Just Expensive ?
The New Reality of Office Ventilation After the COVID-19 pandemic, building owners and facility managers quickly increased outdoor air intake to improve indoor air quality (IAQ). The approach was simple: bring in more fresh air to dilute airborne contaminants and reduce infection risk. Standards such as **ASHRAE ASHRAE Standard 62.1 became the reference point for safer buildings. The result? Safer indoor environments—but dramatically higher energy bills. Many buildings are now paying what could be called a “ventilation tax.” Heating, cooling, humidifying, and dehumidifying large volumes of outside air requires significant energy, especially in climates with extreme seasonal temperatures. In other words, some buildings are healthier—but also far more expensive to operate. The real question today is not whether ventilation is important. It’s how to deliver healthy air without sacrificing energy efficiency. The Hidden Cost of Over-Ventilation Outdoor air rarely enters a building a...
