Abstract: On-line ventilation control based on carbon dioxide (CO2) measurement and the dynamic CO2 balance in indoor spaces has been validated using a dynamic algorithm for two existing buildings. Occupancy profiles estimated using the dynamic algorithm were compared with the true occupancy profiles and the occupancy profiles estimated using a steady-state algorithm based on the steady-state CO2 balance. The dynamic algorithm estimates the changes of occupancy without significant delay. The steady-state algorithm is comparable only at a high air change rate and shows a considerable delay when the number of air changes per hour in a space is small. This phenomenon was investigated using computer simulation.
