Could you ever imagine working in a small city? A new massive office building by Morphogenesis is being built to accommodate over 45,000 people for the Surat Diamond Bourse office in Surat, Gujarat, India. At 603.9 thousand square meter, and housing over 4,000 offices, it will be the second largest office building in the world, placing only behind the Pentagon in Washington D.C. Although its physical footprint may be large, the office building was designed in a manner to minimize its ecological footprint. Passive design strategies such as day-lit workspaces, natural ventilation, and indoor/outdoor spaces not only make the Surat Diamond office an efficient climate-responsive design, but also a key player for achieving aesthetic and comfortable working spaces. Perhaps the largest challenge with a design of this size is how to navigate the large volume of people which would inhabit it. Morphogenesis approached this by designating the ground plane for vehicular movement and podium levels exclusively pedestrian circulation. On this podium level, transportation routes are optimized to create no walking time greater than 4 minutes from an entrance to office module—a design strategy similar to that of airport terminals. The Surat Diamond Office wanted to foster an environment of social interaction and recreation. Over 40% of the building spaces are naturally ventilated, and a dense vegetation fills both the outside and inside of the building. These decisions not only blur the line between interior and exterior but also creating psychological advantages and improving indoor air quality. Additional climate-responsive design techniques are utilized to combat the hot and humid climate of Surat. All offices have been designed to face a pure north-south orientation, and a robust building envelope with less than 30% window area, lightweight concrete block construction and using the advantages of thermal mass by natural brick cladding helps bring down the external heat gains. The efficiency of the building also extends into its construction design. The project represents an innovative approach to low-cost architecture designed with maximum spatial efficiency. Design optimization and simplicity through design modularity diminished project costs to as low as US$ 555.6 for square meter while still maintaining high standards of environmental sustainability.

Work has completed on Tribunal de Paris – a tiered skyscraper, designed by Italian architect Renzo Piano to become the largest law complex in Europe, reported The Dezeen. Comprising a series of stacked glass volumes, the building will bring together the various activities of the French capital's judiciary system, which had previously been scattered about the city. According to publication, the building is not set to open until April 2018. Renzo Piano Building Workshop won a competition to design Tribunal de Paris in 2010. The long and low ground building is designed as a pedestal for the other three levels to rest upon, with the main entrance located on a 6,000-square-meter plaza on the Avenue de la Porte-de-Clichy. Inside, the 5,500 square-meter space is divided into three atria with room for 50 reception desks to ensure visitors are seen as quickly as possible. Each atrium extends up through the full height of the building, with galleries providing access to rooms above and skylights in the roof to allow natural light to filter through. A total of 90 law courts are housed in the pedestal building, most of which benefit from natural light and are all accessible within minutes from the offices in the volumes above. The buildings above each contain 10 stores of meeting rooms and offices for different departments. The first volume will house the magistrates, the second the public prosecutors, and at the top the presiding judges will occupy the third volume. Each building is separated by landscaped roof terraces planted with trees and vegetation. Solar panels have been attached to the exterior and rainwater is collected. Natural ventilation and the building's thermal inertia contribute to regulating the building's temperature. The Tribunal de Paris will unite the regional court, police court, public prosecution courts and the district courts of each arrondissement. Its location on Paris' northern edge, places it at the intersection between the city's administrative zones and the suburbs. The area is well served by public transport, including a new tramway.

According to ctbuh.org, the Council on Tall Buildings and Urban Habitat announced the winners of its annual "Best Tall Building" awards for 2015. This year's winners will be recognized, and the awards conferred, at the CTBUH Annual Awards Ceremony on November 12. All the winning projects and finalists will be celebrated at this gala event. Additionally, from the four regional best tall building winners, one overall winner will be selected and bestowed with the "Best Tall Building Worldwide" award, to be announced on the night. This year's selection was the most competitive yet, with winners selected from a pool of 123 entries, which is up nearly 40% from 2014. Besides this year's winners and finalists are remarkable in that they show a strong commitment to sustainability, with some exemplifying dramatic progress in the use of greenery both to enhance the comfort of the building's users and reduce the environmental impact of the building. Others show dramatic sculptural form and urban presence. The Best Tall Buildings have been named from each of four competing regions in the world, from nominees representing a total of 33 countries. This year are awarded to: "One World Trade Center", New York (Americas); " CapitaGreen " tower, Singapore (Asia & Australasia); Bosco Verticale, Milan (Europe); and The Burj Mohammed Bin Rashid Tower, Abu Dhabi (Middle East & Africa). "One World Trade Center" is a bold new icon for New York City built on the World Trade Center site, whose design acknowledges the adjacent memorial, and whose symbolic importance to the city and the country cannot be overstated. Its form calls to mind several classical New York skyscrapers for which the city is best recognized. The building had high design expectations which the jury felt were met and exceeded. United States and Western Hemisphere tallest skyscraper "One World Trade Center" is 546.2 meters tall, it has 94 over ground and 5 underground floors, 73 lifts and the total area of skyscraper is 325 thousand square meters 40 stories, 242 meters tall skyscraper "CapitaGreen" hasn't any records. It isn't the tallest; more it is only on the 175th place in skyscraper ranking. But Toyo Ito's skyscraper is the green island situated in the heart of Singapore. The building is designed like a plant growing towards the sky. Green living vegetation covers 55 percent of the perimeter of its facade, giving the landmark its iconic appearance. Its innovative double-skin facade features an outer layer of frameless glass and an inner envelope of double-glazed floor-to-ceiling glass that reduces solar heat gain by up to 26 percent. At the top of the tower, a petal-like structure serves as a wind scoop to draw in the cooler, cleaner air from above and channel it though a cool void that penetrates all 34 stories of the building delivering fresh air to tenants. World's first vertical forest "Bosco Verticale" comprises a fantastical pair of luxury high-rises that add nearly 10.2 thousand square meters of lush vegetation to the skyline of Milan, a city notorious for its air pollution. However, "Bosco Verticale", which translates in English as "vertical forest," is more than just a beautiful sight to behold--like a pair of green lungs, its forested facade of 21 thousand plants absorbs CO2 and particulate, dampens noise pollution, lessen the urban heat island effect, and creates oxygen and favorable microclimates. The towers, measuring 80 meters and 110 meters, house 800 trees between 3 and 9 meters tall, over 4 thousand shrubs, and 15 thousand ground cover plants including vines and perennials Middle East & Africa region winner 93-storey, 381 meters high The Burj Mohammed Bin Rashid Tower was designed by Foster+Partners architectural company, and main contractor and developer was Aldar Properties. The Burj Mohammed Bin Rashid Tower is located in the heart of Abu Dhabi at the site of the old Central Market, a traditional crossroads and meeting point in the city. A souk extends the marketplace into the building, facilitating a gentle transition between public and private spaces.
