CIRP Annals, 1997
In 1995, when the previous Design Research in the Netherlands Symposium was organised, the Department of Building and Architecture consisted of four groups working in design research and design computation: Vormleer, the Design Methods Group (GOM), the Bouwinformatica (Building Informatics) Group, and the research institute Calibre. In the period 1997-1998 this situation changed: GOM and BI merged to form the current Design Systems Group, and Calibre became a commercial business under the TUE holding. A new research direction was formulated for Design Systems, based on the existing expertise particularly in design support, CAAD, VR, and design methods. The new research programme was titled VR-DIS. In this paper we will outline VR-DIS, discuss a number of design research approaches that underlie the philosophy of VR-DIS, and present results and ongoing work in the research programme. 14.2 VR-DIS Computational design support is still in its infancy. Among various problems that can be seen, we note, in particular, the following: Most computer applications are task specific and data-exchange between them is difficult. The human-computer interface can be greatly improved to become a fluid medium of expression in the design process, which it is not today. Design representations and design knowledge in the various disciplines are understandable in those disciplines themselves but difficult to exchange. The Bouwinformatica Group and the Calibre Institute had gathered considerable expertise in computational design support, most notably in the areas of visualisation and Virtual Reality technology. From this basis, the following future situation was hypothesised as a context for research: Computational applications that aid in the design of inherently spatial objects (e.g. buildings in Architecture, products in Industrial Design, HVAC systems in Engineering, etc.) will move toward a spatial metaphor. Design knowledge and information of the design stored in the computer will have spatial representations. The motoric and cognitive capacities of designers in everyday life and professional life can be mapped more easily on spatial metaphors than others.

Introduction "Lighting ultimately is not about light, but about people. [u]nless you understand people, love people, are concerned about them and empathize with them, you're not much more of value than a calculator" (Raymond Gernald, 2012). An architectural lighting designer is consulted to fi gure out the technical factors and effects of lighting such as how much light is needed for maximum visual comfort. He/ She chooses lighting fi xtures and positions them on electrical drawings and refl ected ceiling plans (plans showing layout of ceiling). Prominent Professional Lighting designers association include the International Association of Lighting designers (IALD) and Illuminating Engineering Society of North America (IESNA). These are two main bodies regulating and supporting lighting designers. An electrical engineer, civil engineer or architect can professionally work as an architectural lighting designer. A lighting designer must be well aware about the characteristics of a light such as source of illumination, watts consumed, price, lamp's life, extent of reach of light, area lit by it, daylight utilization, colour rendering index (the aspect ratio between how the light illuminates the object by how that object is seen in sunlight, termed CRI), colour, effi ciency and warmth provided by the light (colour temperature). The designer must have command over computer based software for calculating the lux levels in a space.
Color, material and light in the design process a software concept
The paper describes a concept for the IT-support of efficient and plausible planning with color, material and light in the architectural design process. The "Colored Architecture" software prototype described in the paper is a modular part of current research activities at the Bauhaus-University Weimar. In addition to special tools and forms of visualization, the paper describes a concept for the fast, realistic, parameterized assessment of the factors color, material and light in architectural modeling. The traditional rendering of architectural models using radiosity light visualization is often too time-consuming to be used in the design process. To improve the workflow, the radiosity visualization described provides a physically correct visualization of the material whilst allowing the parameters color, material and light to be adjusted interactively. The "Colored Architecture" prototype is an integrated component of the Building Information Model and supports the professional planning of color, material and lighting concepts in architectural design.
Smart Approaches" to Lighting Design (Intelligente Komposition von Lichtquellen in Computergraphiken
Information Technology, 2009
The declarative design of graphics lies at the core of the Smart Graphics research agenda. For 3D graphics the number of lights included, and the properties of these lights, has an enormous impact on what a viewer can judge about the content (the objects), properties (the geometric characteristics and spatial relations of the objects) and other aesthetic qualities of a scene. The traditional approach to lighting design for image synthesis is based on manual design methods, whereby users interactively specify values of lighting parameters, render the scene, and modify the lighting parameters until the desired visual properties of the scene are achieved. Non-expert users encounter a number of difficulties in selecting the appropriate lighting parameters, as the process requires both a subtle technical and aesthetic understanding of lighting in computer graphics. We review range of "smart" lighting design and steady slow convergence on ideal lighting approaches which optimise the lighting configuration for a scene with respect to a set of absolute perceptual metrics. More recently perceptual approaches have been combined with aspects of exemplar driven approaches to yield "lighting-by-example" techniques that can replicate the lighting of existing static 2D images and 3D scenes.
Design and Testing of an Illuminance Management System
Students, the professor, and eight systems engineering advisors for a class project in the fall of 2009 designed a light management system for an operations room for astronomers on Mauna Kea on top of Hawaii. For these astronomers who need constant illumination, BIMS is a light and energy management system that will make them more comfortable and productive, and will save money. Unlike conventional lights and blinds, BIMS will automatically control the illuminance in the room when the sun’s or the moon’s light rays change. The documentation for this design is lengthy; it has been condensed for this article: Parts that do not concern test and evaluation have been eliminated.

This paper traces the various steps of reasoning and development of a numerical model of dimensioning opening-elements based on the reverse approach of simulation of natural lighting. The model was developed by following two steps: firstly the calculation of the external light coming from a sky-element located in the celestial dome. Based on these data, a second numerical calculation was performed to generate the dimensions of an opening-element enabling to realize the daylight intentions of the designer. A method of comparative validation using standard softwares of daylight simulation and daylight optimization was subsequently adopted to test the reliability of the obtained values. Having regard to the pedagogical destination of the tool, the results of this research showed the opportunities that may offer a prospective integration of the developed model in the students’ awareness about the importance of daylight simulation. Therefore optimize the visual comfort and the energy eff...
The Application of Daylighting Software for Case-study Design in Buildings
Proceedings of the 35th International Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe) [Volume 1]
The application of different software, whether simple or complex, can each play a significant role in the design and decision-making on daylighting for a building. This paper, discusses the task to be accomplished, in real case studies, and how various lighting software programs are used to achieve the desired information. The message iterated throughout the paper is one that respects, and even suggests, the use of even the simplest software, that can guide and inform design decisions in daylighting. Daylighting can be complex since the position of the sun varies throughout the day and year as well as do the sky conditions for a particular location. Just because we now have the computing capacity to model every single minute of a day throughout a year, doesn't justify its task. Several projects; an architecture studio, a university office building, a school library and a gymnasium all present different tasks to be achieved. The daylighting problems, the objects and the software application and their outcomes are presented in this paper. Over a decade of projects has led to reflecting upon the importance of computing in daylighting, its staged approach and the result that it can achieve if properly applied.
