History – A blend of classicism and modernism


•The former six-story headquarters building was commissioned by the founder, William Randolph Hearst and awarded to the architect Joseph Urban.

•The building was completed in 1928 at a cost of $2 million and contained 40,000 sq. ft.

•Originally built as the base for a proposed skyscraper, the construction of the tower was postponed due to the Great Depression.

•The new tower addition was completed nearly eighty years later

• A new modernist skyscraper got proposed on the same site in year 2000

The base for the originally proposed

skyscraper.

Hearst Magazine Building 2000 - 2006 Late Modernism period

• Idea of the Tower:– Foster thought of the historic cast-concrete exterior of the Hearst Building as the facade of a town square. – Not enough height between the original floors to create the kind of offices that he thought were needed for a company to function effectively today.– Using the original building would give Hearst "very poky offices," he said, "with very low ceilings”.– Decided to move the office space up into the tower.

– Gut the original interior to create a soaring lobby with a waterfall, a restaurant for the company's 2,000 employees and communal areas for meetings and receptions.

Win-Win Situation•As it is situated above the subway, the project also had to go through the Uniform Land Use Review Procedure. In the end, in exchange for improvements to the subway station—including a new entrance, installing three elevators and adding moving stairwells—Hearst was given a bonus of six floors to add onto the tower.

No vertical structural frames. Gives corner view.

This is the first such case in any North American steel-framed skyscraper.

Features

• Late modernist concept of Space, geometry and light

• Neutral grid• Structure is used as an ornament • Foster’s design preserves the forty six-

story façade of the landmark • From its hollowed-out core rises a

geodesic-like office tower featuring triangular steel bracing from the 10th floor up.

• It will have no vertical columns around the perimeter, creating corner views that are not possible in a typically framed building.

Features


•Diagrid form termed as the ‘birds’ mouths.’ They open up most of the floors and allow a much more panoramic view

Triangular bracing on the perimeter of a skyscraper is not new. It has been done before, most notably for the John Hancock Building in Chicago.

Each of the four-story triangles on the facade is 54 feet (16.5 meters) tall.

Hearst Magazine Building 2000 - 2006This triangular structural framing is very similar to The Hall Of Nations by Raj Rewal,

built 25 years BEFORE this structure!

Diagrid Pattern: More about the Structure"The triangular frames carry the gravity load and has inherent strength and resistance to the lateral loads, seismic and wind

The triangles are so efficient in terms of bearing both the gravity and lateral loads, the building use 21 percent less steel (9,500 metric tons) than a conventional building of its size.

Hearst Tower: Green BuildingFirst green building completed in New York City

An innovative type of glass wraps around the exterior of the building. The glass has a special “low-E” coating that allows for internal spaces to be flooded with natural light while keeping out the invisible solar radiation that causes heat.

The Hearst Tower seems to have perfect thermal comfort all year round due to its complex (and incidental) heating systems.

THERMAL COMFORT

• The floor of the atrium is paved with heat conductive limestone.

• Polyethylene tubing is embedded under the floor and filled with circulating water for cooling in the summer and heating in the winter.

• The base of the tower is mainly composed of a cast stone material, which naturally has thermal mass that helps keep the interior temperatures constant, regardless of what happens to the outside temperatures throughout the day.

• In a nutshell, the system is composed of various parts that control the interior air quality and temperature through convection and radiation methods, while keeping unwanted exterior air under control by controlling conduction routes. As an example of passive design, one of the things this building executes well is proper building insulation.

• The so called “diagrid frame” that holds up the tower is assembled in a way that stops thermal bridges from occurring.

• The recycled steel columns are sprayed with an insulating material, and then surrounded by heavy duty stainless steel sheets.

• In addition, according to the detail images below, wherever floor plates or steel beams meet, insulation is laid down to prevent these points from becoming thermal bridges as well.

• Along with the glass coating, the envelope of the buildings becomes very thermally efficient.

We have seen how the heat flow system of the Hearst Tower atrium is composed of various heating and cooling radiation elements, as well as of elements that minimize unwanted thermal bridging and solar radiation. However, perhaps the most important element to this system is the sculptural piece called “Ice Falls”. It’s a three story waterfall that runs from the third floor level to the lobby on the entry level. Originally intended as a sculptural piece, this waterfall affects the flow of heat and air in the system by either humidifying or cooling the air. This occurs by altering the temperature of the water which in turn affects whether the off steam will want to capture warm air, or release it through water’s convection properties. Then the warmer or cooler air (again depending on the season) mixes with the fresh air that is forced into the space from the outside by HVAC systems, which are located about 10 feet above floor level (depicted in the sectional diagram below by the blue arrows).

It’s one of the few instances in the city where one is able to experience an interior open atrium of approximately 10 floors, filled with natural light from huge clerestory style windows and full skylight windows.


• Rain collected on the roof is stored in a tank in the basement for use in the cooling system, to irrigate plants and for the water sculpture in the main lobby.

• No use of materials, coatings and adhesives that emit volatile organic compounds — known as V.O.C.'s

• Light and motion sensors are installed as well, to turn off lights when people are absent or when there is enough natural light coming the glass outer wall that artificial lighting is not needed.

• Earned a gold designation from the USGBC LEED certification program.


Entering from the existing arch it opens up and what one see is

• three escalators in front to the third floor level.

• Those escalators are set into a sloping water sculpture, which will cascade down past one as goes up.

What sets it apart?

What’s most impressive about the Hearst Tower is the degree to which it justifies the economic sensibilities of environmental awareness. Everything in its design is done to maximize efficiency, but it is also designed to improve productivity, eliminate costs and even improve the aesthetics of a workspace. This is not just about the Earth, the company has said – it’s also good business!

The Tower is more than just a sight to behold – it’s proof of what’s possible

and, given the parade of similar

green-friendly projects now underway, a

benchmark of what’s to come.

Zigging and zagging up the Manhattan skyline, an organic gem blooms in a sea of simple, sterile facades that almost seem archaic in

comparison.

Its unexpected fusion of a modern skyscraper with an original 1928 base

exemplifies the way in which every aspect of its construction has been conceived with

the environment in mind.

• Consuming much less energy than an average office building, this is the first office building in New York City to achieve the US Green Buildings Council's "Gold Rating" for Leadership in Energy and Environmental Design (LEED).

• Hearst Tower garnered the coveted Emporis Skyscraper Award 2006 and for the first time in the award's history, the accolade went for a second time to London's Foster + Partners, winner of the Emporis Skyscraper Award 2003 for 30 St Mary Axe.

• Hearst Tower was a runner-up for the Royal Institute of British Architects' Lubetkin Prize, 2007. Now in its second year, the award (named in honour of architect and founder of Tecton, Berthold Lubetkin) recognises the most outstanding architectural work constructed outside the European Union by a member of the RIBA.

• On 10th October 2007 the building was honoured with a British Construction Industry Award. Now in its twentieth year, the BCIA is Britain's foremost civil engineering and building award and is bestowed on projects outside Britain for which either the primary designer or main contractor is a UK-based British company.

• The building won the prestigious 2008 International Highrise Award.
