Visualizing sustainability in urban conditions

Cities present many challenges for the environmentally conscious
designer. Sustainability is a complex issue comprised of many
overlapping and sometimes contradictory concerns. Overlaid on the
inherent complexity of the urban environment, questions of
sustainability become even more opaque - lost in a multifaceted
network well described by Hough. In such conditions it becomes
very difficult for even well informed and well intentioned
designers to understand the ramifications of their actions. One of
the primary difficulties of sustainable practice in urban
conditions is that many of the aspects of urban sustainability are
invisible - take for example walkability which may have visible
components such as quality of sidewalk or intensity of vehicular
traffic but also has many factors that are invisible or not
readily seeable such as climate, topography that extends beyond
the immediate site, and distribution of amenities. This paper
presents research intended to inform designers in the earliest
stages of design by making several of these factors visible. Using
geographic information visualization (GIV) software multiple
aspects of urban sustainability are mapped and visualized. This
mapping of previously invisible or partially visible issues in the
form of geospatial information provides architects and urban
designers with the ability to process and understand information
about a particular neighborhood's sustainability through the means
with which they are most accustomed - visual information. As way
of example, this research focuses on a particular inner ring
neighborhood in Knoxville, Tennessee, USA.
