Empire State Building Architecture

Empire State Building Architecture

The Empire State Building rises to 1,250 ft (381 m) at the 102nd floor, and including the 203 ft (62 m) pinnacle, its full height reaches 1,453 ft–89⁄16 in (443.09 m). The building has 85 stories of commercial and office space representing 2,158,000 sq ft (200,500 m2). It has an indoor and outdoor observation deck on the 86th floor. The remaining 16 stories represent the Art Deco tower, which is capped by a 102nd-floor observatory. Atop the tower is the 203 ft (62 m) pinnacle, much of which is covered by broadcast antennas, with a lightning rod at the very top.

The Empire State Building was the first building to have more than 100 floors. It has 6,500 windows and 73 elevators, and there are 1,860 steps from street level to the 102nd floor. It has a total floor area of 2,768,591 sq ft (257,211 m2); the base of the Empire State Building is about 2 acres (8,094 m2). The building houses 1,000 businesses and has its own zip code, 10118. As of 2007, approximately 21,000 employees work in the building each day, making the Empire State Building the second-largest single office complex in America, after the Pentagon. The building was completed in one year and 45 days. Its original 64 elevators are located in a central core; today, the Empire State Building has 73 elevators in all, including service elevators. It takes less than one minute by elevator to get to the 80th floor where visitors can take another elevator or stairs to the 86th floor, where an observation deck is located. The building has 70 mi (113 km) of pipe, 2,500,000 ft (760,000 m) of electrical wire, and about 9,000 faucets.[citation needed] It is heated by low-pressure steam; despite its height, the building only requires between 2 and 3 psi (14 and 21 kPa) of steam pressure for heating. It weighs approximately 370,000 short tons (340,000 t). The exterior of the building was built using Indiana limestone panels.

The Empire State Building cost $40,948,900 to build (Equal to roughly $500,000,000 in 2010). Long-term forecasting of the life cycle of the structure was implemented at the design phase to ensure that the building's future intended uses were not restricted by the requirements of previous generations. This is particularly evident in the over-design of the building's electrical system.

Unlike most of today's skyscrapers, the Empire State Building features an art deco design, typical of pre–World War II architecture in New York. The modernistic stainless steel canopies of the entrances on 33rd and 34th Streets lead to two story-high corridors around the elevator core, crossed by stainless steel and glass-enclosed bridges at the second-floor level. The elevator core contains 67 elevators.

The lobby is three stories high and features an aluminum relief of the skyscraper without the antenna, which was not added to the spire until 1952. The north corridor contained eight illuminated panels, created by Roy Sparkia and Renée Nemorov in 1963 in time for the 1964 World's Fair, which depicts the building as the Eighth Wonder of the World, alongside the traditional seven. These panels were eventually moved near a ticketing line for the observation deck.

The building's lobbies and common areas received a $550 million renovation in 2009, which included new air conditioning, waterproofing, and renovating the observation deck; moving the gift shop to the 80th floor. Up until the 1960s, the ceilings in the lobby had a shiny art deco mural inspired by both the sky and the Machine Age, until it was covered with ceiling tiles and fluorescent lighting. Because the original murals, designed by an artist named Leif Neandross, were damaged, reproductions were installed. Over 50 artists and workers used 15,000 square feet of aluminum and 1,300 square feet of 23-karat gold leaf to re-create the mural. Renovations to the lobby alluded to original plans for the building; replacing the clock over the information desk in the Fifth Avenue lobby with an Anemometer, as well as installing two chandeliers originally intended to be part of the building when it first opened.

The Empire State Building: Setting A Green Example


The Empire State Building: Setting A Green Example

The Empire State Building, next to the Statue of Liberty, is probably the most recognizable structure in New York. Tourists flock to it, residents see it nearly everyday and speaking from personal experience, virtually every child in a New York school goes on a tour of it at least once in his K-12 life. So I was thrilled to learn about some of the recent changes to the landmark that have made it even better.
One of the great things about this building is how it’s lit up at night. If the Rangers Rangers win a game, it’s colored red and blue. If it’s St. Patrick’s Day, it’s a vibrant green. Combined with all the tourists that go through it daily, that’s a lot of energy being used for just one building.
Last year’s renovations, however, have made it possible for the building to save 20% of the energy used by the 20,000 workers and 3.5 million annual visitors.
Some of the changes are new elevators that harvest energy with regenerative braking, lights capable of turning on and off by themselves and the largest wireless network of sensors installed in any building on the planet.
“Saving energy without compromise in performance is what’s going to save the world, and that’s the work we set about doing at the Empire State Building,” chief of the Empire State Realty Trust Anthony Malkin said.
In its first year of the renovation, the Empire State Building has saved $2.4 million dollars. When the full energy renovation is complete, the building will save on average $4.4 million a year, enough to pay for the retrofitting in just three years.
The process started back in 2006 when the planning began, but actual work started in 2009 with work crews installing new insulation between radiators sitting below each of the windows and the building’s outer walls, attempting to keep the heat from escaping during colder months.
Each of the building’s 6,514 windows were taken out and installed with a heat-reflective film between the panes while also injecting krypton and argon for added installation. So as not to disturb workers, this process was done entirely at night. Finally, new LEDs light up the building, not only allowing for more energy efficiency, but a wider range of color designs than before.

Empire State Building

The Empire State Building is a 102-story skyscraper located in New York City at the intersection of Fifth Avenue and West 34th Street. It has a roof height of 1,250 feet (381 meters), and with its antenna spire included, it stands a total of 1,454 ft (443.2 m) high.[6] Its name is derived from the nickname for New York, the Empire State. It stood as the world's tallest building for 40 years, from its completion in 1931 until construction of the World Trade Center's North Tower was completed in 1972. Following the September 11 attacks in 2001, the Empire State Building was again the tallest building in New York (although it was no longer the tallest in the world). The Empire State Building was once again demoted to second tallest building in New York on April 30, 2012, when the new One World Trade Center reached a greater height. The Empire State Building is currently the third tallest completed skyscraper in the United States (after the Willis Tower and Trump International Hotel and Tower, both in Chicago), and the 15th tallest in the world (The tallest now is Burj Khalifa, located in Dubai). It is also the fourth-tallest freestanding structure in the Americas.

The Empire State Building is generally thought of as an American cultural icon. It is designed in the distinctive Art Deco style and has been named as one of the Seven Wonders of the Modern World by the American Society of Civil Engineers. The building and its street floor interior are designated landmarks of the New York City Landmarks Preservation Commission, and confirmed by the New York City Board of Estimate. It was designated as a National Historic Landmark in 1986. In 2007, it was ranked number one on the List of America's Favorite Architecture according to the AIA.

The building is owned and managed by W&H Properties. The Empire State Building is currently undergoing a $550 million renovation, with $120 million spent in an effort to transform the building into a more energy efficient and eco-friendly structure. Receiving a gold Leadership in Energy and Environmental Design (LEED) rating in September 2011, the Empire State Building is the tallest LEED certified building in the United States.
