Spatial Mediation: Buildings as Commodities for Exhibitions Discourses – The Case of
the Bienal de São Paulo (1957-2018)
Bienal de São Paulo. Building. Exhibition. Mediation. Space.
This thesis defends the concept of spatial mediation as configurational strategies for the exchange
between people and things which are particularly evident in exhibition spaces – whose main function
is precisely to foster these exchanges. In contrast to other types of mediation, spatial mediation occurs
not through educators or technological devices, but through the system that structures the interaction
between displayed contents and its visitors. This concept is characterized by a double-faceted logic
that concerns the very definition of exhibition spaces – settings for exchange that operate through
the display of artifacts, for cultural and economic purposes. These two facets are made up of pairs of
concepts that address the following issues: 1) discourse and narrative – which describe how things
are arranged in space and how the messages embedded in this arrangement can be interpreted
through spatial navigation; 2) commodity and capital – which represent the syntactic and semantic
role of the building in defining a system of material and symbolic exchanges. These two facets are
objectively represented by the short-term layout of the exhibitions and the long-term layout of the
building that houses it. This phenomenon is investigated at the Bienal de São Paulo (BSP), an
expression that designates both a building (designed by Oscar Niemeyer and his team in 1954), and
a set of exhibitions (with 34 editions, 31 of which held in the same pavilion). This long overlap
between building and exhibitions provides robust evidence for the proposed discussion, which was
obtained through exploratory diachronic studies (on 30 BSP, from 1957 to 2018) and through
specific case studies (on 9 BSP). These studies allowed us to delimit: a) the territory in which spatial
mediation takes place – a spatial system open enough to support a multiplicity of occupations, but
closed enough to minimally structure the movement; b) how it works – by transforming a spatial
system that is simultaneously complex and generic into a system that is highly specific. The first
aspect required the development of three representation models – complex, generic, and specific, to
describe the spatial systems of buildings and exhibitions based on different criteria, thus generating
different levels of network configurations. And the latter enabled the characterization of two types
of special mediation, space as a means and space as an end, whose characteristics describe how the
attributes and elements of the exhibition layout are situated in relation to those of the building layout,
whether within its limits or beyond them (the former related to the notion of commodity and the
latter to a process of commodification). Finally, this approach, which is essentially based on the
distinction between perennial and ephemeral layouts, can provide new perspectives of morphological
thinking for the design and study of uses and internal arrangements of other types of buildings and
spaces.
