Abstract

These days, the problem of indoor air quality (IAQ) attracts increasing attention. Presently, IAQ is usually characterised on the basis of the following parameters: temperature, relative humidity and carbon dioxide concentration. Because of spatial and temporal variation of these parameters multi-point monitoring systems which operate continuously are preferred. The aim of this work was to show that accuracies of sensors being elements of a network have serious implications for a continuous, fixed-point monitoring of IAQ. The analysis was based on four-point IAQ monitoring study performed in a lecture hall. With reference to the measurement accuracy we computed how likely it was that sensors located in different points recorded the same value of measured quantity and how frequently such situations occurred. It was found that: (1) number of sensors and their displacement affect information provided by the measurement system; (2) these aspects should be considered individually for each parameter describing IAQ ; (3) the sensor device dedicated to each measurement point should be considered individually. By considering these issues in the design process the cost of IAQ monitoring network as well as information redundancy may be reduced.
