Abstract
A method of estimating occupancy of a room, comprising: acquiring a plurality of measurements of an aspect of air quality in the room; and estimating the occupancy of the room based on the plurality of measurements and a room ventilation rate parameter. By estimating the occupancy of the room based on aspects of air quality, it is possible to detect occupancy based on data from sensors which may already be present for other purposes (e.g. for measuring air quality). Combining measurements of air quality with knowledge related to ventilation rate results in information indicative of the occupancy. Estimating the number of people in the room allows detailed analysis and control to be undertaken. Such occupancy data can also be used to control other services, e.g. to control the ventilation or to provide information about the number of people present.
