IntroductionThe Morgan Library & Museum is a complex o buildingso diering styles and periods covering hal a city block atMadison Ave. and 36th St. The complex includes three his-toric buildings: an intimate palazzo-like structure designedby Charles Follen McKim in 1902 to serve as the privatelibrary o nancier Pierpont Morgan; The 1928 Annex Build-ing; and Jack Morgans mid-19th century brownstone.

In the years since the Morgans incorporation as a publicinstitution in 1924, there have been several additions to theoriginal library building, including a garden court built in1991 to unite all three structures. In 2006, The Morgan Li-brary & Museum unveiled its largest expansion and renova-tion, a 75, 000sq. t. addition designed by Renzo Piano. TheRenzo Piano design integrates the landmark buildings withthree new, intimately scaled pavilions constructed o steeland glass.

Programmatic OrganizationThe largest pavilion houses the entrance, piazza, the newgallery, and on the top oor, the reading room. A small o-ce tower aces 37th street and the Gilbert Court. The small-est pavilion, between the original library and the annex,contains a perectly cube-shaped gallery.

Piano placed hal the project below ground to gain additional space without eclipsing the surroundingbuildings or compromising the neighborhoods architectural integrity. The multistory basement providesspace or a 280-seat auditorium, a conerence room, mechanical acilities, and a three-story waterproovault or storing Morgans irreplaceable artiacts.

Gravity Loads

The oundation o Pianos inter-vention rests 50 below groundupon Manhattan bedrock,allowing or relatively smallootings. The exterior o thethree-story, watertight vault iscomprised o 1 concrete, whilethe interior is comprised o12W19 steel joists, 14W68 steelgirders, and 96 exposed steelcolumns which support 6 oor

slabs on metal deck. Six 12 X12 steel cruciorm columnssupport the atrium, while thick, 11 deep steel purlinsspanning N/S at 3 intervalsintersect with 2 X 2 squareposts spanning E/W, ormingan exoskeleton that supportsthe skylight system above.

Lateral Loads: The Veirendeel Truss

While the distinct areas within the new campus were conceived as dierent buildings programmatically,they required a structural approach that would enable them to resist lateral loads and otherwise unctionas a single unit. The soaring, low-e glass and steel-enclosed piazza orms a diaphragm that enables thethree pavilions to share wind loads rom the glass acades.

Relation to Existing Buildings

Pianos scheme respects the historical signicance o the site, uniying the complex aesthetically withoutsacricing the essential character o each component; his addition remains seismically independent withno lateral connections to the massive stone buildings. The relationship between the old and the new ismediated by a glass vestibule that doubles as a re stair; by substituting glass risers or the usual opaqueones that would otherwise have blocked views into and out o the atrium, Piano preserves transparency,oering a light-lled space with glimpses o the surrounding context.

Note: During the construction phase, the surrounding historical buildings (which rest above the ounda-tion depth on compacted earth) were secured through underpinning to retain structural integrity and

prevent cracking and settling.

Contextual Integration

Modern and traditional elements were persuasively integrated throughout the campus; Piano, with hisappreciation o renaissance geometry, conceived the addition as a orm o abstract classicism- one withoutthe classical orders but with a traditional sense o restraint, rhythm and balance. This is most apparent onthe building envelope- spare compositions o glass walls and slender panels o steel are proportioned to

blend discretely with the historical abric.

Envelope Typologies

Shaded glazing- the predominant envelope typology- was used when program called or natural light:when a wall, such as in the piazza, this maniests as a ramework o low-e IGUs and steel mullions; when aceiling, such as in the double-height reading room, this maniests as several sandwiched layers. The out-ermost component is an aluminum grille which doubles as a maintenance walkway, ipping upwards to

allow workers to clean the 3 square glass panels below. The innermost layer o the envelope includes shad-ing devices: a roll out translucent woven abric attached to bottom o joists, ollowed by a system o motor-ized louvers which open and close like venetian blinds.

Envelope TypologiesThe secondary typology, which is used when the program requires an opaque condition to protect art, is asteel plate cladding system: 6 wall, 3/8 thick panels are recessed behind a rame with grooved edges, giv-ing the appearance that aade has moldings. It is nished in an o-white architectural paint to echo stoneacades o surrounding buildings.

Design Intention

Pianos extensive use o glazing resulted in a ragile thermal envelope, mandating a robust mechanicalheating and cooling system to counter New York Citys seasonal temperature uctuations. Further, ar-chitectural emphasis on lightness and transparency required an air circulation strategy which minimizedvisual clutter; as an alternative to ductwork, supply plenums were embedded in the oor and return ple-

nums were placed in a dropped ceiling. The return lines in the glass atrium were concealed in the gapsbetween beams and columns.

Programmatic Zones

Heating and cooling systems wereisolated into controlled climaticzones to accommodate varied oc-cupation and programmatic need.

The museum, a light-sensitivespace which required constanttemperature and humidity lev-els, is supplied by AHUs locatedin the basement. The ofces,whose occupation varies basedon employees work schedules, issourced by an AHU located on theroo o an adjacent building. Thetheater, a noise-sensitive spacewhose occupation varies based on

perormance schedules, is sourcedan AHU located in a slanted ceil-ing plenum; rubber dampenersminimize metal to metal contact,circulating air quietly to optimizeacoustics in the auditorium.

Mechanical Piping

The complex uses a steam pow-ered cogeneration system whichconnects to city inrastructure onlevel B2 and orms a circuit withthe AHUs, providing hot watereach or the coils. The chilled wa-ter supply is ed by cooling toweron roo o neighboring building.
