Abstract

High-rise buildings are commonly viewed as an efficient method of land usage for lowering infrastructure costs and for reducing ecological and environmental damage (Alonso, 1964; Muth, 1969; Mills, 1967) . Furthermore, Clark and Kingston (1930), Helsley and Strange (2007), Barr (2008), and Ben-Shahar et al. (2008) account for the symbolic importance of skyscrapers as an additional factor in the motivation in building high. They represent technological advancement, economical strength, and state-of-the-art architecture, and are regarded as a symbol of social and economic status. Moreover, their central location and extreme height further communicate the tenants' social status, which increases the utility retained from high-rise buildings.

This research focuses on the optimal distribution of high-rise building in the urban space.  It offers a framework for evaluating the relative social and economical status of tenants residing in neighboring buildings of different heights. Our methodology includes three stages. We first predicate two basic assumptions that express the relative status between any two neighboring buildings. These assumptions are then articulated as an axiomatic system, defining the basic relative status function, thus enabling us to rank the buildings within a relative status scale. In the second stage we expand the model to assess the economical welfare of an entire cluster of buildings. We develop a platform that enables us to study various criteria for the definition of the term aggregated relative status. These criteria are formulated through objective functions, while using the basic relative status function as a building block. In the third stage of the analysis, we use spatial optimization procedures to generate an arrangement of buildings, optimized according to the aggregated relative status as defined and formulated in the previous stage.

In this research we analyze various test cases based on two normative approaches. We find that both normative approaches tested here exhibit the same optimization pattern. We identify in all test cases a regulated spatial pattern with a tendency to group buildings of the same height and increase distance between buildings of different heights.

Our research method enables us to examine the milieu effects when adding high-rise buildings to an existing spatial texture. Thus we can investigate the changes in nearby tenants' relative status as a result of, for example, plans to build new high-rise buildings in the heart of an existing urban area. Among other contributions, this research provides the urban planner with tools for studying spatial placement according to efficiency and equality criteria when examining social status in the urban region.
