The new Experimental Media and Performing Arts Center
(EMPAC) is located on the edge of the Rensselaer campus overlooking
the city of Troy.
EMPAC is a platform for performance and research incorporating four distinct and specialized venues under one roof: an acoustically optimized 1,200 seat Concert Hall, a 400 seat Theater, and two black box studios created for flexible use by artists and researchers. Also provided are artist-in-residence studios, audiovisual production and post production suites, audience amenities, and student and support facilities.

So that the traditional and the experimental may be seen as
yoked together yet distinct, Grimshaw arranged the concert hall and
atrium axially with the main entrance in a linear sequence on the
north side of the building, while the studios and theater form an
adjacent sequence on the south.
A conceptual dialogue was then initiated between these two
sequences by seeing the Concert Hall manifested as the physical
presence of an object in space, while the Theater and studios
represent the physical absence of discovered voids within a
Because the main entrance is at hilltop level, close to the roof, while the volume of the Concert Hall is fitted into the slope below, a large "found space" opens up between the two. Upon entering the building, visitors find themselves at the top of the Atrium and main circulation area, looking down at the exterior of the concert hall: a curved hull wrapped in solid cedar planks.
Access to the Concert Hall is provided via elevated walkways
that span the atrium like gangplanks. The entire hull of the
Concert Hall is contained within the Atrium, allowing public
circulation all around it.
This use of the topography also creates vistas over Troy toward
the Hudson River, as seen from the campus approach and from major
visitor spaces within the building.
The entire north facade of the building is a glass curtain wall, providing transparency between the EMPAC interior and the city of Troy. The glass wall allows daylight to flood the atrium, augmented by a halo skylight around the top of the concert hall that washes the cedar hull with the changing light of the day. By night, the wood hull is lit up from within the building and creates an iconic external identity that can be seen from distance.
The curtain wall features mullions that carry heated water to insulate the space from the Northern New York winter.
Designed to be a first-class venue for symphonic music, yet equally capable of accommodating jazz, amplified music, presentations, film, and dance with electronically generated sound and video projection, the Concert Hall is configured traditionally in a "shoe box" format: as a long, narrow room of wood and masonry construction.
The floor and lower walls are all finished in maple, while the
upper walls are clad in a combination of precast acoustic panels
made of gypsum and precast stone. The room is slightly convex in
form to maximize acoustic diffusion.
The ceiling is made of panels of fabric less than one millimeter
thick, supported on a delicate web of stainless steel cables. The
fabric was specially selected and woven for EMPAC and is optimized
for gentle reflectivity to high-frequency sound and increasing
transparency to mid- and low-frequency sound, providing acoustic
support to the musicians and audience while allowing the volume
above the ceiling to generate reverberance. The ceiling panels form
a convex shape overall and exhibit a gently glowing surface when
The Theater is equipped to the highest standards available to professional theater companies and offers an extraordinary resource for Rensselaer's experimental artists and student performers. The Theater can be used with or without its orchestra pit. Movable seating at the parterre level, along the sides, allows artists to configure the theater as a proscenium space or to extend the playing area along the sides of the audience.
The framing of the side galleries accommodates the attachment of
projection screens and loudspeakers, allowing the audience to be
immersed in virtual environments. Finished with maple floors and
high-quality plaster walls, the theater has a slightly less formal
treatment than the concert hall, so that its architectural presence
can recede when the stage lights come up.
Studio 1 is a true "black box" venue with minimal architectural
finish, well suited for audio and music but optimized for
scientific visualization, multi-screen and immersive performances,
and dance. The walls are composed of adjustable acoustic wall
diffusion panels and are also painted matte black.
Studio 2 is a smaller sibling of Studio 1, and while being well
suited for dance and visual presentations, it is optimized for
music recitals and recording and therefore has a "lights on"
architectural character rather than being a black box. Studio 2 is
finished with a resilient maple floor and ivory colored adjustable
acoustic wall diffusion panels.
From an engineering and technological standpoint, EMPAC is
state-of-the-art. Each of the contiguous spaces is built in
acoustic isolation from one another. The HVAC system, virtually
silent to preserve the integrity of performances and research, uses
displacement ventilation to push air through registers under the
The massive 20,000-square-foot glass curtain wall features mullions that carry heated water to insulate the space from the Northern New York winter. This is the first time that this technology has been adopted in the United States.
Linked to the university's powerful supercomputer (the Computational Center for Nanotechnology Innovations, CCNI), which will enable complex modeling and visualization, EMPAC will be a platform for the Rensselaer campus, its academic partners, and visiting artists from around the globe to experiment in critical fields.
The design team is submitting the project for Leadership in Energy and Environmental Design (LEED) certification and seeking a Silver rating.
