LiQuID: Lighting Quality In Design

ACADIA proceedings, 2003

In this paper, we present LiQuID, a tool for seeing lighting quality in design. Photographs are useful vehicles for both describing and making assessments of architectural lighting systems. A significant barrier to using photographs during the design process relates to the sheer volume of renderings that needs to be analyzed. Although there have been efforts to produce novel visualization systems to manage large sets of photographs, this research aims to reduce the complexity by classifying data into representative prototypes. A hypothetical case study is discussed.

Abstract This paper reports on the development of a visualization system for architectural lighting designers. It starts by motivating the problem as both complex in its physics and social organization. Three iterations of prototypes for displaying time and space varying phenomena are discussed. Fieldwork is presented to identify where in practice they will be most effective. A set of user studies, one of which is analyzed in fine-grained detail, show how building designers incorporate visualization on hypothetical design problems.

How architects measure light is changing. Human perception of light is ostensibly the reason why spaces are illuminated, yet primary lighting guidelines used by architects measure how much light is falling on a surface, not the distribution of light to the human eye (Cuttle 2011). Recent lighting research related to human visual perception introduces new ideas that, while they challenge the status quo of lighting practice, build on decades of respected prior research. In this paper's case in point, researchers are developing new methodologies and tools to study luminance distribution in built environments (Inanici & Navvab 2006). The concept of studying luminance, or perceived light, instead of only illuminance has long been established in texts by leading lighting designers and researchers (Lam 1977, Boyce 2003, Steffy 2008). This paper aims to provide information on luminance distribution as a factor of emerging importance in the design of quality illuminated environments. To this end, it reviews the use of illuminance and luminance metrics in contemporary architectural lighting practice and research contexts, exposing the objective and subjective aspects of light that these terms measure. It finds that new tools that analyze luminance data from high dynamic range photography and digital simulation models are joined by new lighting knowledge dissemination platforms, together breaking down barriers that prevent architects from designing with luminance concepts. Examination of these research and knowledge tools reveals a shift to a cross-disciplinary, user-centered approach to architectural lighting where realities of human visual perception and surrounding physical contexts enjoy renewed attention.

This paper presents the teaching method used in the lighting section of a design studio on Physical Ambiences (French term for Indoor Climate) at Laval University's School of Architecture. The teaching method comprised studies of daylight strategies in great architectural projects, readings, development of a lighting scenario according to basic biological needs and light transitions, quantitative analyses based on simple performance indicators, scale of shadows and contrast pattern analysis. These analyses were achieved using a variety of tools: physical models, manual calculations and graphical methods, spreadsheet programs, computer simulations, etc. The paper presents the teaching method as well as examples of projects achieved during the studio. The success of the studio demonstrates that it is possible to teach considerably advanced lighting concepts in a relatively short time (2 months). The results are powerful and informative data sets and images that feed the design process and enhance the architectural qualities of the project.

This papers presents an application of realistic rendering to computer aided design in architecture. The application concerns lighting design of buildings. We describe a library of algorithms which allows the simulation of the light sources emittance, surfaces re ectance/transmittance, and light propagation laws. Our general algorithm can compute a physically based simulation of illumination in complex geometric models and o ers the capability to change the inputs without recalculating the entire global physical solution. Since the solution is view independent, hardware graphic accelerations are then used to generate the images. Two industrial experimentations have proved that our system can help designers to evaluate small iterations in the design, as well as compare global alternative solutions. Therefore, design quality improvement can be obtained while saving the costly full scale trials that are necessary when conventional methods are used.

The growing demand for sustainable architectural design motivates the integration of BIM technologies and novel design processes into architectural education. This paper presents the results from a set of educational case studies for the incorporation of BIM-based daylighting simulations and analyses into the design studio. With a carefully devised studio setting and the participation of interdisciplinary consultants, the experimental case studies simulated an integrated design process based on rapid information exchange and collaborative decision making. The implemented method enables students to use BIM models and daylighting simulations as significant sources of design information for performance-based architectural design.

One of the most prominent phrases in the Old Testament is to “seek the Face of God.” According to the late Canadian theologian, Anselme Longpré, there are more than 600 direct references to that phrase in the Old Testament (Longpré 1985:26). It is paradoxical, given that in Ex 33:18, Moses asks to see God’s face, but God did not grant his request, as no human could withstand the glory of the Face (Ex 33:20). An obvious question is how a spiritual being can have a face. There are two camps: 1) the language is hyperbolic, or 2) the text means what it says. It is beyond the scope of this article to come up with a solution to this dilemma. Either way, the term is theologically-laden. Although I will cite just a few of the 600 OT references to the Face of God, my main focus in this short article is to examine how the NT adapts the phrase to the belief that Jesus was God, and as an adjunct, if the Shroud of Turin, believed by many to be the actual burial cloth of Jesus, can be woven into it.
