Green Building (MIT)#Hacks

{{See also|Campus of the Massachusetts Institute of Technology}}

The Green Building was constructed during 1962–1964 using reinforced concrete. It has 18 floors, equivalent to 21 stories or {{convert|277|ft|m}} tall, with a concrete facade that resembles the limestone and concrete of the older MIT buildings near it. The basement of the building is below sea level{{Citation needed|date=January 2011}} and connects to the MIT tunnel system. Three elevators operate in the Green Building. There are staircases at both the east and west sides, whose exterior facades present a vast windowless expanse relieved only by one-story-tall concrete recessed panels.

The first occupied space above the ground level entrance is the "LL" level, consisting of the large Room 54-100 lecture hall. The second floor formerly housed the Lindgren Library, part of MIT's library system, but this separate facility was consolidated into another library in 2009.

From its completion in 1964, the Green Building was the tallest building in Cambridge, until it was surpassed in 2019 by Site 4 in nearby Kendall Square.{{cite news |title=This Week in MIT History |url=http://tech.mit.edu/V119/N47/This_week_in_MI.47f.html |newspaper=The Tech |author=Bushra B.

The building's height has some functional purpose. Its roof supports meteorological instruments and radio communications equipment, plus a white spherical radome enclosing long-distance weather radar apparatus. This technical equipment all requires a line-of-sight vantage point for optimum range and accuracy; without the Green Building, it would have required construction of some kind of tower to function. To minimize interference with radio signals, other buildings on MIT's central campus are less than half the height of the Green Building, and the dormitory towers of Westgate, MacGregor House, and the highrise buildings in Kendall Square are at least {{convert|1500|ft|m}} away.{{cite web|title=Welcome to the MIT Campus Map|url=http://whereis.mit.edu/|work=MIT Campus Map|publisher=MIT|access-date=2011-05-12}}

In 2019, MIT began a $60 million plan to renovate the Green Building. The renovation introduces an additional {{convert|12000|sqft|sqm}} of space for environmental science research, including a LEED-certified addition to the building.{{cite web |last1=Times |first1=Boston Real Estate |title=MIT Plans $60 Million Upgrade to Building 54 That Was Designed by Late I.M.

The Green Building is the main facility of the Department of Earth, Atmospheric, and Planetary Science (EAPS), also known as Course 12. The departmental headquarters is on the 9th floor of the building. The lower floors of the building contain the Planetary Science section. The middle floors have the Earth Science section (Geology, Geophysics, and Geochemistry). The upper floors house the Atmospheric Science section (which also includes Oceanography and Climatology).

When the Green Building was first opened, the isolated prominence of the building and its relative proximity to the Charles River basin led to high wind speeds in the archway at its base. Strong winds sometimes prevented people from entering or leaving the building through the hinged main doors, forcing occupants to use a basement tunnel connecting to other buildings.{{cite interview|url=http://libraries.mit.edu/archives/oral-history-transcripts/dickson-pdf/dickson9feb2005.pdf |title=William R. Dickson Oral History Project |author=Interviewer: Susan Crowley |publisher=MIT Institute Archives & Special Collection |date=February 9, 2005 |access-date=2014-05-29}} Large wood panels were temporarily erected in the open concourse to block the wind, and revolving doors were later installed at the ground floor entries to somewhat ameliorate the problem. Several windows cracked and at least one large windowpane popped out on an upper floor, in part due to the effects of wind, eventually requiring all the windows to be replaced. A few years later, similar problems occurred in Boston's John Hancock Tower, a 60-story skyscraper designed by the same architectural firm.

After the wind problems became obvious, aerodynamic model tests were conducted in MIT's Wright Brothers Wind Tunnel.{{cite arXiv |last1=Kalmikov |first1=Alexander |title=Uncovering MIT wind myths through micro-climatological CFD analysis |eprint=1310.3538 |class=physics.ao-ph |year=2013 }}{{rp|17–20}} In 2013, a computational fluid dynamics (CFD) study re-examined the complex airflow around and through the building. The studies confirmed the anecdotal stories of unusually strong winds at the base of the building, explaining the phenomenon as the result of a large stagnation pressure perturbation at the southern face of the building.

A popular but incorrect myth states that Alexander Calder's sculpture La Grande Voile (The Big Sail) was installed in front of the building to deflect the strong winds. The 2013 CFD study demonstrated that the sculpture is located too far away to significantly alter wind flow at the base of the building.{{cite news |url=http://tech.mit.edu/V126/N36/36artsinterview.html |title=List Curators Discuss Evolving Face of Public Art by Benjamin P.

Because of its height and visibility from the Boston Back Bay neighborhood across the Charles River Basin, plus its rectangular grid of large {{convert|6|x|8|ft|m|adj=on}} upright rectangular single-pane windows forming a crude 9 × 18 dot-matrix display, the Green Building has been the site of many hacks or pranks.{{cite web|title=Hacks on The Green Building (54)|url=http://hacks.mit.edu/Hacks/by_location/54.html|work=MIT IHFTP Hack Gallery|access-date=2011-05-08}} In 1993, one widely viewed hack repurposed the nine top-floor windows as an enormous digital VU meter for the traditional Fourth of July concert of the Boston Pops orchestra.{{cite web|title=The Green Building Sound (VU) Meter |url=http://hacks.mit.edu/Hacks/by_year/1993/green_bldg_vu_meter/|work=MIT IHTFP Hack Gallery|access-date=2011-05-08}} Several other simpler hacks have used the entire window array for stationary displays; this practice is sufficiently commonplace to have acquired the term greenspeak{{cite book|last=Institute Historian T.F.

In September 2011, hackers installed 153 (= 9 × 17) custom-made wirelessly controlled color-changing high-power LED lights into every window above the first floor. They displayed a waving American flag throughout the evening of September 11, 2011 in remembrance of the September 11 attacks of 2001. For a short time in the early morning of September 12, the lights displayed a Tetris game, thus realizing a long-standing hack proposal, the "Holy Grail" of hacks. The display hardware had occasional glitches, and was removed as of September 13. The hardware and software designs were further developed and refined for better reliability. On April 20, 2012, MIT hackers successfully turned the Green Building into a huge, playable Tetris game, operated from a wireless control podium at a comfortable viewing distance in front of the building. Visitors to Campus Preview Weekend (a gathering for admitted prospective freshman students) were invited to play the game on the colossal {{convert|80|x|250|ft|m|adj=on}} display grid, which was claimed to be the second-largest full-color video display in the US.{{cite news |last=Pourian |first=Jessica J. |title=The 'holy grail' of hacks: The construction of one of the most anticipated hacks of all time |url=http://tech.mit.edu/V132/N22/tetris.html |volume=132 |number=22 |newspaper=The Tech |date=May 1, 2012 |access-date=2012-05-06 |archive-date=May 4, 2012 |archive-url=https://web.archive.org/web/20120504235800/http://tech.mit.edu/V132/N22/tetris.html |url-status=dead }}{{cite news |last=Parker |first=Brock |title=Hackers convert MIT building in giant Tetris video game |url=http://www.boston.com/yourtown/news/cambridge/2012/04/hackers_convert_mit_building_i.html |newspaper=Boston Globe |date=April 24, 2012 |access-date=2012-05-06 }}{{cite web |title=Tetris on the Green Building |url=http://hacks.mit.edu/Hacks/by_year/2012/tetris/ |publisher=MIT IHTFP Hack Gallery |access-date=2012-05-06}}

Instead of a one-shot temporary installation, the hackers have designed and built a permanent facility that can be re-used repeatedly by the MIT community. An understanding has been reached with the Department of Earth, Atmospheric and Planetary Sciences (EAPS), which is headquartered in the Green Building, to allow the light display hardware to remain installed in each window. To avoid annoying the occupants and to allow late-working staff to "opt out", each light display is equipped with a manual override button, which will disable the pixel lighting for that window for several hours after it is pressed. In addition, the hackers have released open-source software tools used to develop new display patterns, so that others can design and deploy new stationary or animated images, in cooperation with the hacker engineers.

On the night after the Boston Marathon bombing, the Green Building lighting displayed an American flag pattern.{{cite news |author=MIT News Office |title=MIT's Green Building pays tribute to the week's events |url=http://web.mit.edu/newsoffice/2013/mits-green-building-pays-tribute-to-the-weeks-events.html |access-date=28 April 2013 |newspaper=MIT News Office |date=April 21, 2013}}{{cite web |last=Kennedy |first=Shred |title=Famous MIT Green Building Displays American Flag Lights After Bombing |url=http://theawesomeboston.com/famous-mit-green-building-displays-american-flag-lights-after-bombing/ |work=The Awesome Boston |publisher=The Awesome Boston |access-date=28 April 2013 |url-status=dead |archive-url=https://archive.today/20130630100707/http://theawesomeboston.com/famous-mit-green-building-displays-american-flag-lights-after-bombing/ |archive-date=30 June 2013 }} After the shooting death of MIT Campus Patrolman Sean Collier by the alleged bombers a few days later, a {{convert|250|foot|m}} black ribbon pattern was displayed in his memory.

As of 2020, the light display was no longer functional.

As a prototype feasibility demonstration, the Tech Model Railroad Club (located in Building N52) had years earlier added a scale model of the Green Building to its HO scale model railroad layout. Passersby inside Building N52 can view the model building and railway layout through a large window and play a monochromatic version of Tetris via remote control, accompanied by authentic-sounding music, even when the facility is closed.{{cite web |url=http://tmrc.mit.edu/TNP/GC/GreenBuilding.html |title=Green Building |publisher=Tmrc.mit.edu |access-date=2011-03-12 |archive-url=https://web.archive.org/web/20110720104347/http://tmrc.mit.edu/TNP/GC/GreenBuilding.html |archive-date=July 20, 2011 |url-status=dead }}

Other hacks utilize the height of the building, such as a 1974 failed attempt to operate a giant yoyo from the roof of the tower.{{cite news |last=Moore |first=Barb |title=Unusual Activities |url=http://tech.mit.edu/V93/PDF/N56.pdf |volume=93 |number=56 |page=3 |newspaper=The Tech |date=January 16, 1974 |access-date=2011-05-12}}{{cite news |title=Front page photo caption|url=http://tech.mit.edu/V94/PDF/N5.pdf |access-date=2011-05-12 |newspaper=The Tech |date=February 22, 1974 |volume=94 |number=5 |pages=1, 4}} Launching of projectiles from the roof is strongly discouraged, risking deflection by the unpredictable high wind gusts and posing a serious danger to passersby and to residents of nearby East Campus dormitory.

At midnight on the last Saturday of October, First West (the smallest hall in the East Campus dorm) drops a large number of pumpkins (up to the low hundreds) off the roof of the Green Building. The event frequently attracts a large audience, and the area around the base of the building is quarantined off to prevent accidental injury.{{cite web|url=http://mitadmissions.org/blogs/entry/pumpkin-drop1 |title=Pumpkin Drop |author=Lydia K.

In May 2011, a temporary artwork was installed in the arched "breezeway" at the base of the Green Building, to take advantage of its legendary wind gusts. Designed by Meejin Yoon, an Associate Professor of Architecture, Wind Screen was an array of wind-driven micro-turbine generators that would light up whenever there was enough air movement.{{cite web|title=Meejin Yoon: Wind Screen|url=http://arts.mit.edu/fast/meejin-yoon-wind-screen/|work=Arts at MIT [website]|publisher=MIT Council for the Arts|access-date=2011-05-08}} This installation was featured in the FAST (Festival of Art, Science, and Technology) celebration, part of the MIT 150 commemoration of MIT's 150th anniversary.
