Sky Tower

Abstract: This work proposes an iconic landmark for Jeddah presented in a Sky Tower that would possess a symbolic, aesthetic and historical value. In this work, three case studies were evaluated. Based on the case study analysis, the estimated gross floor area for the sky tower is 23607 m2. The sky tower is comprised of several zones such as main lobby, commercial area, cultural area, amenities, sky pod, offices rental and administration. Furthermore, in this work, three sites were proposed for constructing the sky tower. Based on site evaluation analysis, site 3 was selected as the proposed development site, as it had attained the highest evaluation score of 93. This sky tower would bear recreational facilities for unforgettable experiences creating a "sense of place" for Jeddah as well as boost its tourism attraction. Jeddah Sky Tower would reflect the beauty, the cultural and innovative ingenuity and the social richness of Jeddah acting as a high profitable enterprise influencing a variety of visitors to approach.

It has encouraged architects to develop exotic designs that enhance the publicity of a town with a more appealing and acknowledged picture to become a tourist destination, cultural hub, business district, and so on [3]. Consequently, iconic architecture produces a separate and recognizable picture of the town. It represents the identity as well as the particular aesthetic or symbolic or historical values connected to a place, making it famous as a construction in the industry between architects, planners, technicians and the public [3].Iconic structures are strong instruments for marketing towns to become highly photogenic tourist destinations and an arch tourism fuel to create advertising and attract tourists [4]. Therefore, the image of an iconic building could usually turn to a symbol of the new identity of the city, giving them a visible distinction and positioning themselves as destinations, for example, how the Burj Khalifa was a symbol of Dubai [5]. Towers have been used throughout history to either honor important events or establish particular points in a certain location [6]. This vertical structure provides architecture a more elegant and pleasant glance from an artistic point of view [7]. Jeddah is the capital of Saudi Arabia and it one of the most visited places around the globe. Jeddah serves as a tourist spot for visitor of Makkah and it is also a port city with commercial hub for tourist. Therefore, this work proposes the development of an iconic landmark, Jeddah Sky Tower in Jeddah's skyline boosting Jeddah's tourism by creating an entertainment hub with a variety of recreational facilities and a sky tower overlooking the city. CASE STUDIES In this work, three case studies were analysed . The case studies selected are: a. Toronto CN tower b. Blossoming Dubai Tower c. Taiwan Tower Toronto CN tower Toronto CN tower is located at Toronto, Canada (Figure 1). It was designed by architect John Andrews. This building has an site area of 159000 m2 and gross floor area of 167000 m2. The structure of this tower is comprised of tower, glass floor, pod, revolving floor and exterior elevator. It was build using futurism material such as glass, steel, concrete and reinforced concrete. The sky pod is 7 stories and consists of indoor and outdoor observation decks and a revolving restaurant. The tower is backed by a Y-shaped foundation, with each side gracefully widening to blend into a main hexagonal nucleus. The tower includes fast lifts, double sheet, armor-plated windows, a rotating café and viewing places at the top of the tower. This building has several facilities such as sports center, heritage center and convention center. Figure 1. Toronto CN tower

Abstract: Each year Auckland city gains about ten new high rise buildings, each taller than the buildings they replace. While each has its own impact on its local wind environment, together they have a variety of effects on the general wind environment. Although the local effects are controlled to some degree by the requirements of the Resource Management Act and the Auckland City District Plan, the general effects occurring as the result of the combined growth of the city is less controlled. One example of this was discovered during a wind-tunnel study of the winds affecting Sky Tower, where it was shown that the combined effects of the tall buildings in the Central Business District create increased wind velocities and turbulence levels at heights between 70m and 200m. This paper will discuss both the local and general effects that tall buildings have on the wind environment of Auckland City.
