John McAslan + Partners created a canopied addition to the historic King's Cross Station, leaving the original western facade intact.

Heralded for its historical importance but rather drab, London’s King's Cross Station recently underwent a multimillion dollar redevelopment, reopening to the public on March 19, 2012. The newly overhauled King’s Cross Station was lit up in celebratory bright colors, creating a concert-like atmosphere – appropriate to its new youthful vibe. It was a timely redevelopment, as the XXX Olympic Summer Games will be held in London in 2012. The station’s western concourse, at 7,500 m2, is Europe’s largest single-span station structure. Each year 45 million people pass through King’s Cross Station, and that number is predicted to rise by 10 million by 2020.

Jeddah, Saudi Arabia, is slated to become the home of the world’s tallest building.

Jeddah, a city of three million in the Kingdom of Saudi Arabia, will soon be known for having the world’s tallest building. The Kingdom Tower, as it will be called, is a design conceived by Adrian Smith + Gordon Gill Architecture (AS+GG), a Chicago-based firm. Smith, while at SOM, partnered on the design of the current tallest building in the world – the Burj Khalifa in Dubai, United Arab Emirates.

Pythagoras Solar undertakes a pilot project to install solar windows on the Willis Tower (formerly the Sears Tower) in Chicago. The project should provide data on the potential use of glass facades to collect solar energy.

Pythagoras Solar is conducting an experiment on one of the most iconic structures in the world – the Sears Tower, now Willis Tower. Established in 2007, Pythagoras specializes in solar panels for windows, focusing particularly on skyscrapers and other tall buildings. Skyscrapers have little rooftop area to accommodate solar collectors but use an extensive amount of glass use in their facades. These expanses of glass result in astronomical heating and cooling costs. Skyscrapers also contribute to a localized retention of heat known as urban heat island (UHI) effect, and large cities such as Chicago are looking for ways to mitigate that heat retention.

On the southeastern tail of Ontario, the 175-year-young city of Toronto is home to 2.5 million Canadians, making it the largest city in the country. Rodolphe el-Khoury, an architecture professor at the University of Toronto, said in a 2008 interview that he noticed an underlying rural tone in Toronto's architectural identity. “It’s a kind of tension between a cosmopolitan international culture and a more Ontario-based kind of heritage,” described el-Khoury. What Toronto is known for is its skyscrapers – it is second only to New York as having the most in North America. Along with the skyscrapers, progressive-minded young people who champion environmental friendliness inhabit downtown Toronto.

As the world is facing an energy and resource crisis, we are realizing more and more the importance of sustainability. This is especially true within the hospitality industry. Corey Enck of the U.S. Green Building Council (USGBC) recently stated in a press release that “In the United States alone, hotels represent more than five billion square-feet of space, nearly five million guest rooms, and close to $4 billion in annual energy use.” Due to the unique challenges hospitality projects can present, the Hospitality Adaptations Working Group was formed to create a sustainable design model that the industry could follow.

What was once a three-story Japanese Army headquarters building from the 1930’s in the Cool Docks development on the South Bund District of Shanghai, China, has been renovated into a four-story, 19-room boutique hotel. Completed in May 2010, the Waterhouse at South Bund was designed by Neri & Hu Design and Research Office (NHDRO). Shanghai designers Lyndon Neri and Rossana Hu founded NHDRO, which has received internal and domestic awards for their designs in China, Taiwan, Hong Kong, England, Canada, Spain, and the Netherlands.

An unassuming giant box covered in green is camouflaged by surrounding trees and grass. Pedestrians hurrying by may take little notice of it, while some might curiously ask, “What is that?” It is a 2008 project called the Green Technology Showroom by Vector Architects that inhabits the central lawn of a residential compound in the Guanganmen district of Beijing, China.

Your eyes sweep across the panorama. Rolling hills are bursting with colorful wildflowers of vivid orange, yellow, and purple. A Bay Checkerspot butterfly dances by in the flickering light reflected by what looks like a pond but is in fact a skylight of Renzo Piano’s California Academy of Sciences building. Piano worked with Academy scientists and a team of California professionals, including Stantec Architecture from San Francisco, to revitalize the California Academy of Sciences building, located in San Francisco's Golden Gate Park.
