The u u e o building design emphasizes ene gy e iciency and clima e esilience, aiming

3.1.1. Building esilience
Building esilience can be de ined as he abili y o a building o adap o, espond o, and

p olonged d ough s, and in ense ain all, esilience plays a cen al ole in bo h he design

This concep goes beyond me e s uc u al esis ance and encompasses he building's
