The Spatial Openness Index: An Automated Model for Three Dimensional Visual Analysis of Urban Environments

Fisher-Gewirtzman D., Wagner I.
Vol. 23, Number 1, Spring, 2006.

Abstract: The main focus of the SOI model is the dense urban environment. The dense urban environment is currently a problem, and its significance will grow in the future. Openness to near and distant views influences the quality of life, and the environmental quality in a densely built urban environment is reflected in real estate values. It is well known and proven in research (Benson, et al ., 1998) that people are willing to pay a premium for a preferred view. The shape of buildings and the …

Spatial Openness as a Practical Metric for Evaluating Built-Up Environments

Fisher-Gewirtzman D. & Wagner I.
Vol. 30, 37-49. 2003.

Abstract: This paper reports on a primary metric tool developed in a collaboration between an architecture researcher and a computer science researcher. The development of this tool emerged from the concept that the spatial openness (SO)—the volume of free space measured from all possible observation points—is an important quality indicator of alternative spatial configurations within given constraints; this concept is…

A 3-D Visual Method for Comparative Evaluation of Dense Built-Up Environments

Fisher-Gewirtzman D., Burt M. & Tzamir Y.
Vol 30, 575-587. 2003.

Abstract: The work reported here is a contribution by the authors to the search for reliable metric method for spatial evaluation, related to human erception of `openness’ and to the development of evaluation tools for urban planning and design. A recent innovation, the `spatial openness index’ (SOI), a quantitative index, based on a three-dimensional visual analysis of space is applied here.
This approach reflects the hierarchical order found in the urban environment: dwelling unit, building…
