Climate Analysis
Wind Analysis
Based on this analysis, I conclude that the prevailing winds occur primarily during the summer and fall. Creating open space at the ground level would enhance natural ventilation, which is particularly beneficial for a site located in a dense urban context. In addition, the UTCI map indicates significant heat stress during the summer months; therefore, incorporating shaded areas at the ground level would greatly improve occupant thermal comfort.
Daylight Analysis
To identify which parts of the building require additional façade shading to mitigate excessive direct sunlight penetration, we first perform a daylight analysis on the building's basic massing. The results indicate that the south- and east-facing façades receive the highest levels of solar exposure. Based on this analysis, implementing shading strategies on these façades becomes a key design approach for reducing unwanted solar gain before finalizing the façade design.
View Analysis
Based on the view analysis, the residential levels experience minimal visual obstruction, while the lower podium—housing retail, office, and common spaces—exhibits a higher degree of view blockage. As a result, we concentrate more complex and denser façade treatments at the podium level, where views are less critical, and employ a more transparent façade system for the upper residential levels to preserve unobstructed views.

Facade Design Strategy
Based on the results of the previous analysis, our façade design strategy is divided into two components. First, a curtain wall system is applied as the base façade across all building modules. Second, at the podium level—which accommodates office, retail, and common spaces—a curved, wavy parametric screen is introduced outside the curtain wall at varying depths. This layered façade system provides solar shading while allowing controlled openings that facilitate natural ventilation for interior spaces. The geometry and depth variation of the screen further enhance environmental performance while contributing to the architectural expression of the podium.
