Airflow reduction to improve building comfort and reduce building energy consumption - a case study Academic Article uri icon


  • To remedy comfort problems in a 99,000 ft2 (9,200 m2) office building, the total airflow rate was reduced by 35%, and the total outside airflow was reduced by 86% in four multi-zone air-handling units that serve the office building. After the airflow reduction, the peak room relative humidity level was reduced from 70% to 55%, and cold and hot deck reset schedules were implemented. These improved operating practices reduced building energy consumption by 27%.
