Abstract: To assess the thermal comfort in the indoor spaces such as office rooms, generally thermal sensors are mounted in the workplaces. The main drawback of this conventional method is recording data at certain locations instead of distribution of the target parameter in the entire room including the occupant zone. To address this gap, the application of Acoustic traveltime TOMography (ATOM) is proposed which is based on the first order dependency of sound velocity on the air temperature. This study reports research on development of the ATOM measuring system at the Bauhaus-University Weimar to measure the indoor air temperature distribution. The measurement results reveal the applicability of the ATOM-measuring system for high-resolution monitoring of air temperature distribution in the workplaces of the future.
