Abstract
This paper presents a dynamic method for detecting the actual occupancy in indoor spaces by measuring the carbon dioxide concentration of the return air and the outdoor air flow rate. The accuracy and response speed are tested and compared with the steady-state detection method. An on-line outdoor air flow control strategy using the dynamic detection method and the validation of the strategy are presented. The indoor air quality and energy performance of the demanded ventilation using this strategy, two CO2-based demanded control strategies and the strategy of constant outdoor air flow, are compared and evaluated under various occupancy and outdoor weather conditions in simulation.
