The perception of a room being unpleasantly close, lacking fresh air, and feeling confined, often described as having poor air quality, stems from several potential factors. This condition indicates an imbalance in the room’s atmospheric composition and temperature, leading to discomfort. Stagnant air, elevated carbon dioxide levels, and increased humidity contribute to this sensation.
Addressing this issue is crucial for maintaining occupant health and well-being. Poor ventilation can exacerbate allergies, promote the growth of mold and mildew, and negatively impact concentration and sleep quality. Historically, buildings were designed with natural ventilation strategies. Modern construction, with its emphasis on energy efficiency, often creates tighter building envelopes, necessitating mechanical ventilation systems to ensure adequate air exchange.
