Abstract:In the late 1980's and early 1990's a range of approaches to using fractal geometry for the design and analysis of the built environment were developed. Mandelbrot's "box counting" approach was later refined and developed by Carl Bovill (1996) who demonstrated a method for determining an approximate fractal dimension of architectural elevations and plans. This paper is the first investigation of the fractal dimensions of five house designs by Kazuyo Sejima, a famous, late 20th century minimalist designer (Aoki… Show more
“…But exactly how visually different are they? Fractal analysis is rare method which has been employed on multiple occasions to examine historical buildings (Burkle-Elizondo and Valdez-Cepeda, 2006;Ostwald, Vaughan Tucker, 2008;Ostwald, Vaughan, Chalup, 2008;). Bovill's (1996) method in particular, has been widely used even though it has only recently begun to be sufficiently refined for widespread application (Lorenz, 2003).…”

Architectural historians are divided over the question of whether or not Le Corbusier's early, Arts and Crafts (or Art Nouveau) style chalet designs are formally related to his later, more famous, designs for Modernist villas. While there are multiple stylistic differences between Le Corbusier's early and later works, the question remains, are the houses really so different in terms of their formal complexity? The present paper uses computational means to mathematically answer this question for the first time. Recent research has shown that computational methods can be used to determine a series of quantitative results for the visual complexity of five of Le Corbusier's Modernist houses (completed between 1922 and 1928). In this paper five of Le Corbusier's early, pre-Modern house designs (completed between 1905 and 1912) are analysed using the same computational method. With these two sets of data available for testing, a detailed comparison of the mathematical difference between the works is constructed. Ultimately, this paper concludes that there are strong correlations between the formal complexity and design strategies found in these ten canonical works.

“…Architectural researchers have also used a manual variation of fractal analysis to measure the visual properties of contemporary and historic buildings (Bovill 1996;Bechhoefer and Appleby 1997;Burkle-Elizondo, Sala, and Valdéz-Cepeda 2004;Burkle-Elizondo and Valdéz-Cepeda 2006;Gozubuyuk, Cagdas, and Ediz 2006). More recently, a dedicated computational version of the method has been developed specifically for architectural analysis (Ostwald, Vaughan, and Chalup 2009;Ostwald and Vaughan 2010;Ediz and Ostwald 2012). However, despite the growing number of applications of this method, past research has noted that, because of inconsistencies in the way it has been applied, different measures can be derived from an analysis of the same elevation of a building (Zarnowiecka 2002;Lorenz 2003;Vaughan and Ostwald 2009a).…”
Over the last two decades, a range of computational techniques have been developed for measuring the formal characteristics of architecture. One of the most widely used methods, fractal analysis, measures the typical or characteristic spread of visual information (form and texture) present in a plan or elevation. However, when preparing a plan or elevation for this method, several critical decisions must be made about which architectural features should be included in the representation and why. Without a consistent, reasoned way of making such decisions, isolated fractal dimension results for buildings are potentially meaningless. Therefore, the present paper draws on postpositivist reasoning to propose a framework for deciding which lines in an architectural representation are significant for a study and why. The framework contains five cumulative levels of representation that are defined and mapped against comparable research agendas. These levels are described and demonstrated using a plan and an elevation from Le Corbusier's Villa Jaquemet. In each case, the results of the fractal analysis of different representations of the Villa are used to demonstrate how decisions about significant lines have a direct impact on measures derived from fractal analysis.
“…What factors influence our well-being when living in a particular urban neighbourhood ? Some studies proposed, for example, the involvement of harmonic ratios, others calculated the fractal dimension of façades and skylines to determine the aesthetic value of façades, street-and cityscapes [5,7,24,31,32,43].…”
This interdisciplinary study proposes a method for architectural design analysis of house façades which is based on face detection and facial expression classification. The hypothesis is that abstract face expression features can occur in the architectural design of house façades and will potentially trigger emotional responses of observers. The approach used statistical learning with support vector machines for classification. In the computer experiments the system was trained using a specifically composed image data base consisting of human faces and smileys. Afterwards it was applied to a series of test images of human facial expressions and house façades. The experiments show how facial expression pattern associated with emotional states such as surprise, fear, happiness, sadness, anger, disgust, contempt or neutral could be recognised in both image data sets.
