Research on the Reconstruction Design of the Closed Atrium of the No. 1 Office Building of Wuhan Kaidi

Taking the atrium reconstruction project of the Wuhan Kaidi No. 1 office building as an example, this paper expounds on the closed atrium reconstruction project’s unique design methods. This study optimizes the atrium from the aspects of architectural aesthetics, structural stability, energy saving, and lighting performance. An asymmetric umbrella structure is used to support the atrium roof. The advantage of this umbrella structure is that the roof components are more uniform, and the atrium roof can be aesthetically “floating”. In addition, applying aluminum and glass panels at the top of the roof will directly affect the thermal and daylighting environment inside the atrium. Simulation technology realizes the trade-off design of energy consumption and daylighting index in this study. The simulation results show that the optimal comprehensive performance can be achieved when the area ratio of the glass and aluminum panels on the atrium top is 1:2. This study can provide a reference for other similar projects.
