Which characteristic is essential for an occupied space regarding air supply?

An essential characteristic for an occupied space concerning air supply is that it should be equalized with exhaust. This means that the amount of air being supplied to a space should be balanced with the amount of air being exhaustively removed. This balance is crucial for maintaining indoor air quality, temperature control, and overall comfort. When air supply and exhaust are properly equalized, it helps prevent issues such as negative pressure, which can lead to drafts, discomfort, and an influx of unfiltered air from outside. It also aids in ensuring sufficient ventilation, which is necessary for removing contaminants and maintaining fresh indoor air. This equilibrium is vital for effective HVAC operation and energy efficiency.
