  ### The buttressed‑core concept

  - Y‑shaped plan resists torsion and channels wind.  
  - Tiered setbacks “confuse” vortices to reduce sway.  
  - Foundation: a massive raft and piles distributing load into desert geology.  

  ### Elevator strategy

  - Zoned high‑speed lifts, sky lobbies, service shafts.  
  - Express runs reduce transfer times for visitors.  
  - Redundancy and evacuation planning baked into shaft layout.  

  ### Facade and climate

  - High‑performance glazing tames heat gain.  
  - Maintenance cradles and rope teams service impossible angles.  
  - Sealing, tolerances, and cleaning regimes for desert dust.  

  > Fun fact: On clear days, the temperature can be several degrees cooler at the top than at ground level.
