Cover Story: The MoBiMet (Mobile Biometeorology System) is a low-cost device for thermal comfort monitoring. It measures air temperature, humidity, globe temperature, brightness temperature, light intensity, and wind and is capable of calculating thermal indices on site. It visualizes its data on an integrated display and sends them to a server, where web-based visualizations are available in real time. Data from many MoBiMets deployed in real occupational settings were used to demonstrate their suitability for large-scale and continued monitoring thermal comfort. This article describes the design and performance of the MoBiMet. Alternative methods to determine mean radiant temperature were tested. Networked MoBiMets can detect differences of thermal comfort at workplaces within the same building, and between different companies in the same city. View this paper
