Skyscraper Design and Sustainability Challenges

The video explores the evolution of skyscrapers, from their American origins in the 1880s to modern global landmarks. It highlights technological advancements like steel construction and elevators, which enabled taller buildings. Post-WWII innovations introduced glass curtain walls, while suburbanization shifted urban landscapes. The global race for the tallest buildings saw cities in Asia and the Middle East adopting new designs to withstand environmental challenges. The focus now is on sustainability, balancing urban needs with environmental impact.
