This paper presents the results of a field study concerning indoor conditions in an office space in
Grieskirchen, Upper Austria. The office is equipped with a displacement ventilation (DV) as well as
personal ventilation (PV) systems. The space can also be naturally ventilated through the manual
operation of windows (NV). The main objective of the study was to assess the functionality of the
mentioned ventilation systems with regard to indoor air quality and thermal comfort. The configuration
of the indoor climate control system in this office allows for the performance evaluation of the
ventilation systems through different methods. In fact, the monitored data and short-term user surveys
provide a basis to document the indoor conditions and their implications for the occupants. Our
study also illustrated the utility of calibrated CFD models toward a better understanding of the
airflow phenomena and estimation of the airflow velocity as an input data for calculation of predicted
mean vote (PMV) values. The results suggest that the combined operation of the above mentioned
systems provides in general acceptable indoor environmental conditions. However, optimal
operation of the systems installed requires the continuous and comprehensive monitoring of
indoor conditions, systems states, and occupants´ feed-back.
