Analysis of economic viability of personal ceiling fans using building simulation

Knudsen, Mattis


The present work addresses the question of economic viability of ceiling fans in comparison
to different cooling concepts for office buildings. An office building in southern Germany that
had been refurbished and supplied with a night ventilation system and ceiling fans was
modelled. This model was used to compute the parameters to evaluate the indoor air.
Occupant behaviour for working hours, window opening behaviour, and ceiling fan usage
was deduced from available models and monitoring data. The available data for the inside
air temperature served the calibration process of unknown parameters and the validation of
the whole model. Four different concepts were implemented to the model: night ventilation
with ceiling fans, as installed in the examined building, air-conditioning system, night
ventilation without ceiling fans, and a system with no cooling or ventilation. Processing the
simulation results, thermal discomfort hours due to warm indoor temperatures in the building
was assessed. Namely, the predicted mean vote (PMV) and thermal sensation vote (TSV)
were calculated and compared amongst the different concepts. A productivity evaluation
