Carbon dioxide measurements (top), ambient flow measurements (middle), and inferred number of occupants for APS office building Feb. 21-March 12, 2012. Note the difference between weekdays and weekends. Note also that the peak occupancy is around 400 and that the typical double peak observed before and after lunch times.
Calculating concentrations of people in buildings

Estimating the number of occupants in a building at any given time is key for determining the heating and cooling loads as well as ventilation rates necessary to maintain comfort and air quality co
