Summary / Abstract:

ENThe existence of stratification in high-ceiling buildings is real, but not visible or easy noticeable by humans. For field measurements, the Prayer House – The Kaunas Basilica of the Resurrection of Christ, located in Kaunas, Lithuania, was chosen, in which the temperature distribution at different heights (6 m, 8 m, 10 m, 12 m, 14 m, 16 m and 18 m) during the heating season was observed. The Basilica had radiant heaters installed at 5 m height. According to the plan of the Prayer House, CFD model was created, and the temperature distribution of the different heating (radiant heating and floor heating) systems were compared. The IDA-ICE modelling of energy consumption was conducted using the CFD results as a basis, and the economic analysis was performed based on the obtained results. The study confirmed the existence of stratification in high-ceiling buildings. Keywords: stratification, high ceiling buildings, radiant heaters, energy efficiency, FloVent, IDA-ICE, CFD.
