  58. 58. Tall Buildings: Advantages and Disadvantages
  59. 59. Street Activities• Tall buildings create a hostile urban canyon that prevents visual and functional continuity between different parts of the city.
  60. 60. Spatial Continuity• Also, an important connection between tall buildings and the city is how they prohibit or allow for spatial continuity between different buildings.
  61. 61. Conclusion• Tall buildings canhelp create awarenessof our lifestyles andpatterns ofconsumption negativeimpacts on theenvironment.• Tall buildings make abig, visible publicstatements ofsustainability.
  62. 62. Towards Sustainable Tall Buildings.• Tall buildings make a big, visible public statements of sustainability; i.e. incorporation of wind turbines, green facades and roofs, cultural references and materials selection.
  63. 63. Creating Commercially and Culturally ViableBuildings• With 800 tower projects expected to be completed over the next decade in the Middle East, it is important to retain a sense of cultural identity and heritage.
  64. 64. Creating Commercially and Culturally ViableBuildings• This can be achieved by developing projects with a sense of community, based on modern urban living concepts where traditional Arabic architecture is combined with sophisticated technologies that enable a sustainable outcome.• Future generations might judge our tall building strategies as fashion and branding.
  65. 65. Think • The trend to construct tall buildings may be driven both by pragmatism and desire for distinction. • When it comes to building tall structures, the physical construction of the building is not particularly difficult. • We could keep building floor after floor until we reach the moon.
  66. 66. Realize Whilst technology may enable us to build tall, the fundamental question is should we continue to build tall, if yes then how!
