This paper discusses the validation and adjustment of the CO2 based occupancy detection algorithm introduced by Calì et al. (Calì, 2015), based on new data gathered at the E.ON Energy Research Center main building in Aachen in 10 multi-person offices. In addition to the new data basis, further adjustments of the algorithm to the given conditions and possible future improvements are discussed. This paper will also discuss other occupancy detection algorithms, e.g. ones based on VOC, humidity or a combination of different measurements.
