Parametric Model for Window Design Based on Prospect-Refuge Measurement in Residential Environment

Abstract

As the concept of prospect-refuge defines a preferred environment, the spatial elements that provide good conditions for the catalyst of the theory have been extensively studied. The well-known architectural element of this theory is the window that optimizes visual openness to outdoor or enclosure from outdoor. The aim of this paper is to develop a design method for prospect-refuge condition by adjusting window design attributes. A parametric design model that measures spatial conditions and presents design alternatives for the window is proposed in two major phases. First, this paper explains a parametric model to generate design alternatives for a window according to its size, aspect ratio, location, and shape. In the second phase, the parametric algorithm is defined for the measurement of prospect-refuge with 3D visibility. As a result, we explore the impact of window design variables on average visibility and difference visibility of prospect and refuge area. Using the parametric design technology, the proposed method presents analytical techniques, considering spatial characteristics.

How our homes impact our health: using a COVID-19 informed approach to examine urban apartment housing

“…The theory of prospect-refuge (Appleton, 1975) purports that people naturally prefer varied environments that include places where they can see activities but cannot be easily overlooked by others. Windows that provide residents with a "lookout" view of the city street or greenspace, act as a source of prospect (Hwang and Lee, 2018). The feeling of refuge can be achieved in spaces where the resident feels a sense of retreat and security within their home.…”

Seemo: A new tool for early design window view satisfaction evaluation in residential buildings

“…In computer-aided design (CAD), view content can be quantified computationally by testing a 3D model for visibility using rays -this approach is known as Raycasting and was first introduced by Benedikt [30]. Hwang and Lee [31] used Ray-casting from a given point in a room to measure window parameters and obtain the 3D visible area from the observer's position. The ray intersection is used to identify the view element type (e.g.…”

“…Substituting Equation (25) into Equation 20, and combining with Equations (26)- (31), the curvature variation energy of cubic T-Bézier curve r(t; λ, µ) can be simplified as follows:…”

“…Gao et al [30] proposed a GE-Bézier-based parametric identification method of human gait differences, and discussed its application in rehabilitation training. Hwang et al developed a parametric design model that measures spatial conditions and presents design alternatives for the window [31]. The previous methods have the following problems: Partial or overall shapes of products designed by previous parametric methods are difficult to modify and it is inconvenient to quickly obtain various styles of product styling solutions.…”
