“Second Avenue Subway Project Causes 50% Rise in Prices” – New York Times, September 2, 1929

The idea for a Second Avenue line was first brought up in 1920 when NYC’s public transit was at maximum capacity moving around 1.3 billion riders per year having doubled since the pre-war years. When an official plan was introduced in September 1929, home prices increased 50% almost overnight. However, because of the Great Depression, WWII, and then the Korean War; the city did not break ground until 1972. But then in 1975 the project was abruptly stopped when the city ran out of money. Revived again in the mid-nineties, construction on the current line started in 2007.

“But it is highly improbable that the Second Avenue subway… will ever materialize.” – New York Times, January 17, 1957

Aside from the financial and political reasons that delayed the train for a century, the fact is that it is much more difficult to construct a new subway line in today’s New York than it was in the 1920s. When New York’s first subway line opened in 1904 there were less people, less buildings, and less regulations. At that time, crews would use the “cut and cover” method where they would close the road, dig up the street, and then cover it back up when finished – a feat that would be nearly impossible in today’s bustling Manhattan.

“Ground was broken yesterday for the Second Avenue subway.” – New York Times, October 28, 1972

In today’s New York, the city must use explosions (video) to help make way for the huge boring machines, reinforced with high-strength steel, that are able to cut underneath the foundation while cars and people are left undisturbed on the surface. Running 24 hours per day, these tunnel boring machines can dig around 50-60 feet per day leaving a huge underground path for the trains.

While it is obvious that steel would be used in these projects, the sheer amount is astounding. From the tunnel boring machine to the steel wheels that ride on the steel tracks to the stainless steel subway cars — steel is everywhere. In fact, it was the advances made in steel technology in the 1880s that made New York’s first subway a reality. After the great blizzard of 1888 shut down city streets and brought down the electric power grid, the city started to make efforts to put things underground. In addition, the same advances in steel provided for taller and taller buildings that brought more and more people; so, the city needed a new form of transportation that could move everyone from their homes to their jobs. The NYC subway system started in 1904 with just 28 stations – it now has 468 stations running a total distance of 1,055 km (656 mi).

Subways have redefined urban life in the modern era. This feat of engineering, like so many other urban wonders, is only possible because of the steel used to dig, build, and operate the subways.

Both individuals and corporations must become more environmentally responsible, being mindful of the levels of waste water, trash and emissions produced both at home and in the office. Considering these factors in the architectural designs of the future, we can ensure a healthy and sustainable planet. Yet, a number of buildings are a step ahead and have already incorporated sustainability into their own designs, setting the precedent for future architectural endeavors. On this World Environment Day, let’s take a look at a few of them.

Northeast Asia Trade Tower (NEATT)

Standing 68 stories tall, the Northeast Asia Trade Tower in Songdo International Business District, Incheon, is the tallest structure in South Korea. It is also the crown jewel of POSCO’s leading innovative technology, utilizing revolutionary features such as a 3D exterior design, a seismic force resisting system and high level security and anti-disaster measures.

Yet, NEATT, which is a mix of office spaces, a luxury hotel, serviced residences and retail stores, also serves as a model of sustainable design strategies, carefully balancing energy conservation, increased indoor environmental quality and occupant comfort. Its range of passive design strategies, which include daylighting, natural ventilation and energy efficient HVAC systems, as well as its eco-friendly, non-toxic construction materials, have ensured that the skyscraper is not only friendly to the environment, but to its human inhabitants, too.

Monte Rosa Hut

Perched above the skiing mecca of Zermatt, Switzerland, the Monte Rosa Hut is a lodging space used by hikers in route to the summit of the same name on icy glacier treks. The five-story crystal-shaped building was constructed on stainless-steel foundations with a wooden spiral interior covered by a silver aluminum shell. During its construction, materials and workers were transported by train to Zermatt, requiring 3,000 helicopter trips.

The hut uses solar power for about 90 percent of its energy and heat requirements. Excess energy is stored in valve-regulated lead-acid accumulators, which ensure power in all kinds of weather. Large windows allow the sun to heat air inside the building, and melting glaciers in the area provide the lodge’s water supply, which is collected and stored in a nearby reservoir. (Image from http://bit.ly/1AJVsUa)

Meera Sky Garden

Perhaps no other building on this list is as one with nature as the Meera Sky Garden in Sentosa, Singapore. This eye-catching, eco-friendly home was designed by Guz Architects, and it overlooks the island’s harbor.

Divided into four distinctive floors, each of which is covered with a grass roof, the home appears as if it is four separate houses, yet is still seamlessly connected by a natural element. Not only are these garden-like spaces visually pleasing, but the grassy roofs help to keep the interior temperatures at a minimum, saving energy. (Image from http://bit.ly/1ddeBTx)

Pixel

While Pixel’s chaotic, colorful exterior is the first thing one might notice about the small office building in Melbourne, Australia, its sustainable design is what really makes it noteworthy. Some of its design innovations include a panel shade system that allows natural light into the office, while at the same time, reducing glare and heat. More impressively, Pixel utilizes wind turbines to generate its own electricity.

As Australia’s first carbon neutral office building, Pixel was also the first building to ever be granted a perfect score on the country’s Green Star sustainability rating system. (Image from http://bit.ly/1JoxIpS)

Bank of America

When the Bank of America building was erected in Manhattan, New York in 2009, it set the standard for all environmentally responsible buildings to come. Its base-to-roof insulating glass external structure enhances heat insulation while creating a large source of natural light, while the building’s extensive solar panels produce energy for the building.

And the Bank of America knows how to save water. Its greywater system collects and recycles waste from sinks and water fountains into the refrigeration system, while its catchment systems collect and save around 45 inches of rain that fall on the site each year. Such sustainable features landed the skyscraper the LEED Platinum Award, the highest level of the internationally recognized green building rating system.

The Change Initiative

In a city that is seemingly ever under construction, The Change Initiative (TCI), an eco-lifestyle shop that stocks everything from environmentally-conscious detergent to greywater recycling tools, sets itself apart from other buildings in Dubai.

Often noted as one of the most sustainable commercial buildings in the world, the majority of the materials used to create TCI are recyclable. The roof is coated with heat-reflective paint and is embellished with solar panels that generate about 40 percent of the building’s energy, while the building’s outer structure has three times the insulation of the average building. (Image from Gundeep Singh)
