The Impact of Building Parameters and way of Operation on the Operative Temperature in Rooms

The control of the thermal environment and the assessment of the quality of rooms in terms of thermal comfort of users is often based solely on the measurement of the air temperature. Proper assessment should, however, be based on an analysis of the operative temperature, which, in many cases, differs from the air temperature in the room. The operative temperature takes into account also the influence of surrounding building partitions on building occupants due to thermal radiation. The paper analyzes the impact of building elements such as the construction of the building walls, the size of the glazing, building orientation, as well as the way the building is operated on the differences between the air temperature and the operating temperature. Multivariate simulation analyzes were carried out for an exemplary office room using the IDA Indoor Climate and Energy (IDA ICE) program.
