C01 - Applications of Fractal Patterns for Green Building Wellness

Wednesday, November 20 from 4:00 PM to 5:00 PM | B312 « Back

Abstract Text:

In this session, it will be discussed the implications of WELL v1 Building Standard and LEED v4 BD+C & ID+C rating systems requirements of the design of daylighting, interior quality views can work with fractal geometry design. Previous studies have shown that views of nature and daylighting collectively and independently were associated with positive perceptual, physiological, and psychological impacts on human well-being. To elicit these positive responses from building occupants, biophilic design principles have emphasized the importance of integrating natural systems at various building design scales. However, one of the questions that has plagued researchers is: What elements or characteristics distinguish views of nature from other view types, such as urban views or views of other human-made systems? This session will provide a possible explanation to this question by applying the fractal theory and geometry to architectural spaces. Fractal geometry is based on self-similar patterns that repeat over a range of magnifications. These patterns are prevalent in nature (e.g. trees, coastlines, clouds). Studies by several researchers have suggested that the fractal geometry in nature is what triggers such positive responses. To address this interdisciplinary topic, practitioners and researchers from three fields (Architecture, Physics, and Psychology) will present recent results from several studies and will discuss the application of fractal patterns in architectural design. In these studies, we projected different light patterns on a wall in two and three-dimensional compositions and assessed the visual preference, mood and visual interest elicited by them. We found that projected fractal light patterns of mid to mid-high complexity were significantly more visually preferred and more visually interesting than other patterns. Furthermore, we show that fractal patterns can balance excitement and relaxation better than other patterns. For biophilic design, this session will highlight the importance of incorporating nature-based geometry (fractals) in interior spaces to improve occupants’ satisfaction. This session is sponsored by IWBI
