Part 2-Environmental Prediction of the Original Design in the Entrance hall by CFD analysis

Abstract

In order to separate the exhibition space from the entrance hall to avoid possible external disturbances, glass partitions that were not part of Le Corbusier's original design were added after the building was completed. We used computational fluid dynamics to predict the air environment under the original design conditions with various air conditioning zoning plans. If the original design is restored with the present air conditioning zoning, there would be an increased risk of moisture condensation on the glass surface of the entrance hall. However, this risk was confirmed to be significantly reduced by subdividing the air conditioning zone and changing the air conditioning controls in each subdivided area.
