Over half a million individuals will be served by a group of reclaimed land masses that serves as a central component of “Next Tokyo 2045.” The Sky Mile Tower boasts 421 stories and can accommodate 55,000 individuals, with a total area of approximately 4.5 million square feet (1.4 million square meters). This immense structure is part of the Next Tokyo initiative, which showcases a thriving city capable of adapting to climate change. It stands at a height more than double that of the world’s tallest building, the Burj Khalifa (2,716 feet; 828 meters). The Sky Mile Tower is an incredibly tall skyscraper, reaching a height of 1 mile (5,577 feet or 1,700 meters), and is planned for construction on the waters of Tokyo Bay in 2045.
The visionary Tower Mile Sky is a mega-skyscraper built on water that transforms less-efficient horizontal growth into more vertical growth, bringing life into urban land.
Conceived by the collaborators of Kohn Pedersen Fox and Leslie E. Robertson, the Sky Mile Tower was an immense edifice that Tokyo architects have envisioned for over half a century. With the city’s population rapidly expanding and limited land availability, the idea of this structure linking the shores of Tokyo Bay was born.
At the core, the Sky Mile Tower is the focal point, wherein the undertaking comprises of a linear district spanning 8.7 miles (14 km) and featuring robust infrastructure, as well as a collection of reclaimed land masses forming an archipelago. These individuals are the identical collaborators involved in the “Next Tokyo 2045” initiative.
Within this water district for transportation, there will exist open spaces for recreational purposes in addition to the towering Sky Mile Tower, which measures 5,580 feet in height. The objective of Next Tokyo 2045 is to protect Tokyo Bay from both natural calamities and human-induced dangers such as rising sea levels and typhoons, as the architects and engineers possess a positive outlook on the future of the Tokyo metropolis.
The Tower Mile Sky is a remarkable piece of architecture that can completely alter the cityscape and make it more flexible. This supertall building is especially important near large bodies of water, as it will become more and more crucial for cities to move people and adapt to environmental changes. It will also become increasingly important for megacities along the coast to have architecture that is resistant to urban growth and environmental risks.
The Design Characteristics of the Sky Mile Tower
Tokyo Next forms a protective line across Tokyo Bay, enclosing the Sky Mile Tower to keep it safe from the harmful effects of navigating without waves. This is achieved by a series of hexagonal rings of infrastructure with widths between 500 feet and 1,500 meters, reducing the waves’ impact.
Some of the objectives of its design are secure and robust, reliable, efficient, and sustainable. This new mega-tall symbolic structure, known as the Sky Mile Tower, represents a significant technological advancement in architectural design.
Within the towering edifice, elevated outdoor areas are strategically situated in areas with reduced air currents. The skyscraper’s multiple residential communities, accommodating a population of 55,000 individuals, are interconnected through a sequence of sky lobbies on various levels and boast shared amenities such as shops, dining establishments, accommodations, fitness centers, libraries, and even healthcare facilities.
The Sky Mile Tower is made up of several interconnected sets of three building legs and has a hexagonal base. Each set consists of legs from stories 90 to 60, with one pair of building legs overlapping with another set at each level. This structure repeats all the way to the top.
In the event that the life-support system in these buildings fails, there is an elevator or stairwell available to transfer points between the different levels. This occurs every 320 feet (1,050 m), connecting the lobbies on each floor of the six-story building, providing access to the sky rooms.
The threat of strong winds
The horizontal forces applied by the wind surpass the vertical loads on the levels since the specifications for wind in a super tall building like this surpass those for seismic activities, even in areas prone to earthquakes.
The Sky Mile Tower solves this problem by strategically incorporating a number of openings that allow air to flow through. Any tower at this height is likely to experience long periods of shaking, which can be easily initiated by wind.
The Tower’s Mile Sky benefits from significant aerodynamic advantages provided by the vertical slots and tapered shape, enabling efficient airflow through its resilient structure and effectively disrupting the wind.
The building’s perimeter is supported by small columns, holding up the concrete floor. These columns are strategically placed every 30 or 40 stories and are reinforced by belt trusses. Belt trusses are utilized to transfer column loads to concrete shear walls.
Sky Mile Tower Skyway Transportation
The residents of Sky Mile Tower will have access to the new brand of rail system, known as the “Hyperloop” or vacuum-tube transport, specifically served by the main water district station called Next Tokyo, which is located approximately 2.5 miles (4 km) offshore, connecting the two coastlines of Tokyo Bay through tunnels.
Moving 55,000 people is not an easy feat, especially when it comes to overcoming the difficulty of magnetic levitation in the Sky Mile Tower, which utilizes a multi-purpose elevator. The structure of the tower is uniquely designed with a tapering and slanted shape.
The MULTI system does not use ropes to move the cabins along magnetic fields. Instead, the cabins move along rails in the elevator shafts, connecting four different sky lobbies and five different residential areas in the Sky Mile Tower.
Additionally, their routes cover multiple residential areas and the shuttle lifts also provide direct service from the building entrance to the sky lobbies. By moving horizontally to a neighboring shaft, the cabins will create a seamless loop by changing directions at the top and bottom of each section of the building.
The following sky lobby is accessed by these shuttles, aligning with the adjacent building’s leg and vertical shaft after undergoing a horizontal transfer at the interlocking zone. These shuttles traverse the building’s support columns, running alongside the nearby cabin shafts.
How Will the Sky Mile Tower Produce Its Own Energy?
One of the ways to obtain energy from the sun is to use photovoltaic cells. Another method is to put microturbines on the top levels of the tower to harvest kinetic energy from passing trains in the harbor. Additionally, there are several other methods to obtain power from the wind, including the use of the Sky Mile Tower.
Used as a sustainable and effective energy source, this system will collect saline bay water for growing algae, while the expansive infrastructure encircling the Sky Mile Tower will accommodate diverse scales of urban agriculture.
The primary facade of the Sky Mile Tower will feature extensive agriculture, and there will be communal gardens and rooftop farms as additional facilities.
Using different sizes of locally grown crops will make the Sky Mile Tower more reliable in supplying food. This method will also consume less energy to store food and decrease the likelihood of food being destroyed or lost due to weather conditions.
Water Pumping and Warming the Dwellings
The Tower Mile Sky can house a huge number of people while leaving a small footprint on the natural world, by using atmospheric conditions at higher altitudes to meet the demands of water and cooling. The facade of the tower moves around the legs, increasing the surface area and making it possible to get water from the ground instead of clouds.
Assisting in the reduction of temperatures in the lower floors, the colder air surrounding the upper levels of the tower will be employed. Subsequently, it will be gravitationally dispersed, gathered, purified, and centrally stored at various levels within the tower. This eliminates the necessity of pumping water from the ground to the uppermost floors in the Sky Mile Tower.
A self-sufficient water system is incorporated in this mega tower, eliminating the need for external sources of potable water. It combines blackwater recycling methods like mechanical and biofiltration processes with cloud harvesting and rainfall collection systems.
The Tower Mile Sky communities are linked in another intelligent way that allows effective transfer of waste heat, in addition to improving energy efficiency, by using technology called micro-grid as a backup source of electricity in case of blackouts.
Electricity generated from water can produce both cold and heat. In CCHP facilities, the same amount of valuable materials can be recycled while increasing the use of natural gas. This, in turn, reduces the amount of trash ending up in landfills. To achieve this, organic waste is carefully managed with an on-site anaerobic digester.
The Price of Constructing the Sky Mile Tower
The proposed structure, known as the Sky Mile Tower, is estimated to cost at least $100 billion to build, making it the tallest tower in the world. In comparison, the Tokyo Tower, with estimated costs of $25 billion, and the Ultima Tower, with costs of $210 billion, as well as the X-Seed Tower, with costs of $1.3 trillion, are more affordable visionary endeavors. However, the exact cost of constructing the Sky Mile Tower remains a mystery.
