The design of the envelope in high-rise office buildings is a task of great importance
as it can impact the entire building's energy performance. The study presented in
this paper is an extension of a previous work reporting on the optimization of the
façade and the shading systems of an east-west facing high-rise office building. This
study aims to investigate the façade geometry design factors for other potential orientations,
e.g., south, south-east, and south-west directions. The IDA ICE 4.8 complex dynamic
building energy simulation program was used to assess thermal and lighting simulations.
The optimization results revealed the best-performing façade configurations, appropriate
for each orientation examined in terms of thermal comfort, visual comfort, and energy
consumption.
