title The Pattern That Connects
source ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 125-132
summary While patterns have a spotty history in architecture, their definitions and uses in other fields offer new possibilities for design. This paper examines those definitions and uses—including theories put forward by architectural theorist, Christopher Alexander; art educator, Gyorgy Kepes; chemist, Ilya Prigogine; and anthropologist, Gregory Bateson. Of particular interest is the shift from eternal, essential, universal, and fundamental patterns to fleeting, superficial, specific, and incidental versions. While endemic to many contemporary architectural practices, this multifaceted view of patterns was anticipated by Bateson, who saw them as agents of evolution and learning. His desire to combine redundancy and noise offers architects new ways to understand patterns and use them to link form and information, matter and thought.

title Software design of maintainable knowledge-based systems for building design
source Automation in Construction 4 (2) (1995) pp. 101-110
summary Identifying and establishing a basic structure for knowledge representation is one of the keys to successful design of knowledge-based computer systems. In Building Design and Construction, this initial knowledge structure can be achieved by utilizing a query driven approach to software engineering. As (user) queries reflect the user's demand for in/output, it is natural to link the overall user dialogue with key elements in the knowledge base direct connections between user screen and objects in the knowledge base support prototyping and testing the application during development. However, the price for pursuing this approach in its pure form can be high, as needs for later maintenance and augmentation of the system can be very hard to fulfill. To overcome these problems, a strict user interlace, software separation strategy must be. introduced at early stages of software design. and implemented as a global control module as independent of the knowledge processing as possible.

title Measuring the Usability, Efficiency and Effectiveness of CAAD Tools and Applications
source Stouffs, Rudi and Sariyildiz, Sevil (eds.), Computation and Performance – Proceedings of the 31st eCAADe Conference – Volume 1, Faculty of Architecture, Delft University of Technology, Delft, The Netherlands, 18-20 September 2013, pp. 147-155

summary Computer Aided Architectural Design (CAAD) decisions and judgments have been at the heart of architectural design practice. Despite the increasing popularity of computer aided design applications, measuring the decision making of designers empirically remains elusive. Past research claiming usefulness of the CAD has relied largely on anecdotal or case studies that are vulnerable to bias. The study reviews results of prior investigations. The relatively few laboratory experiments report hardly any empirical results regarding the measurement of CAD decision making. The study provides an overview of the literature of existing measurement methods that have been used in psychology and neuroscience to assess individual variations in design making, and highlight these different measurement methods’ strengths and weaknesses. We conclude with a comparative evaluation of the different measures and provide suggestions regarding their constructive use in building realistic theories of designer’s decision making measurement.

title Responsive Acoustic Surfaces: Computing Sonic Effects
source RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.819-828

summary Acoustic performance is defined by the parameter of reverberation time; however, this does not capture the acoustic experience in some types of open plan spaces. As many working and learning activities now take place in open plan spaces, it is important to be able to understand and design for the acoustic conditions of these spaces. This paper describes an experimental research project that studied the design processes necessary to design for sound. A responsive acoustic surface was designed, fabricated and tested. This acoustic surface was designed to create specific sonic effects. The design was simulated using custom integrated acoustic software and also using Odeon acoustic analysis software. The research demonstrates a method for designing space- and sound-defining surfaces, defines the concept of acoustic subspace, and suggests some new parameters for defining acoustic subspaces.

title Reactive Light Design in the ""Laboratory of the Street"" Esben Skouboe Poulsen, Hans Jørgen Andersen"
source ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 333-342
summary This paper presents and discusses results related to a full-scale responsive urban lighting experiment and introduces a light design methodology inspired by reactive control strategies in robot systems. The experiment investigates how human motion intensities can be used as input to light design in a reactive system. Using video from 3 thermal cameras and computer vision analysis; people’s flow patterns were monitored and send as input into a reactive light system. Using physical as well as digital models 4 different light scenarios is designed and tested in full-scale. Results show that people on the square did not engage in the changing illumination and often they did not realized that the light changed according to their presence. However from the edge of the square people observed the light patterns “painted” on the city square, as such people became actors on the urban stage, often without knowing. Furthermore did the experiment showcase power savings up to 90% depending on the response strategy.
