title A Decomposition Model as a Tool for Evaluation of Multi-Cell Solutions : A Case Study
source pp. 470-481 : ill. Haifa, Israel: Technion Research and Development Foundation Ltd., March 1978. no. 021-223. includes bibliography
summary A decomposition-recomposition model that was recently developed by the authors, is applied as a tool for evaluating the layout of an actual design problem composed of 130 activities. The evaluation is performed by comparing the suggested design solution, in terms of space allocation, with a theoretical solution obtained through the model which is set up as a norm for the evaluation

title A Knowledge Based Computer- Aided Solar Design System
source ASHRAE Transactions (American Society of Heating, Refrigerating and Air-Conditioning Engineers). Atlanta, GA: 1990. v.st.-96-2: [5] p. : ill. includes bibliography
summary A knowledge based computer-aided architectural design system (KB-CAAD) for the schematic design and evaluation of passive solar buildings is presented. The presented tool is based on the integration of knowledge based and procedural simulation methods with any available CAAD system for building representation. The knowledge base contains the heuristic rules for the design of passive solar buildings. Whenever possible, the knowledge base guides the designer through the decision making process. However, if 'rules of thumb' are not acceptable for the particular design problem, the KB-CAAD tool guides the architect towards the optimal solution, by using a procedural simulation model. It is demonstrated, through a case study, that the proposed knowledge based design system not only leads to the design of better solar buildings, but that it takes less time and man-power to introduce the geometrical data that would be needed for a regular non-solar building representation

title Learning from Collaborative Integration:The Hackathon as Design Charrette
source Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 233-240
summary This paper examines the application of innovative and interdisciplinary collaboration methods that emerged from the rapidly developing field of information technology and its intersection within the realm of design and architecture. These events, also referred to as hackathons, have risen in popularity in recent years (Artiles & Wallace, 2013) and stem from a design response for the increasing demand for accelerated design decisions within the field of architecture. This paper examines the potential of hackathons as a platform for rapid development of design ideas into prototypes within a time constraint of 24 hours. The paper explores the hackathon as a robust foundational element for pedagogical approaches rooted in interdisciplinary collaboration. Using a case-study research methodology, this paper probes the framework of the event, the outcomes, and the lessons learned. As this paper demonstrates, the hackathon required participants to identify and explore shifting territories through interdisciplinary teamwork to arrive at innovative solutions. In this setting, the format of the hackathon serves as a vibrant territory that enables a concrete theoretical contribution to design pedagogy, CAAD education, and collaborative professional practice.

title Combined Procedural and Heuristic Method to Energy Conscious Building Design and Evaluation
source New York: John Wiley & Sons, 1992. pp. 305-325 : ill. includes bibliography
summary This paper describes a methodology that combines both procedural and heuristic methods by means of integrating a simulation model with a knowledge based system (KBS) for supporting all phases of energy conscious design and evaluation. The methodology is based on partitioning the design process into discrete phases and identifying the informational characteristics of each phase, as far as energy conscious design is concerned. These informational characteristics are expressed in the form of design variables (parameters) and the relationships between them. The expected energy performance of a design alternative is evaluated by a combination of heuristic and procedural methods, and the context-sensitive application of default values, when necessary. By virtue of combining knowledge based evaluations with procedural ones, this methodology allows for testing the applicability of heuristic rules in non-standard cases, h)0*0*0* Ԍ thereby improving the predictable powers of the evaluation

source Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures 91 Conference Proceedings / ISBN 3-528-08821-4] Zrich (Switzerland), July 1991, pp. 465-484
summary A knowledge-based computer-aided architectural design system (KB-CAAD) for the design and evaluation of solar and low energy buildings is presented. The KB-CAAD system is based on the, integration of knowledge-based and procedural simulation methods with any available CAAD system for building representation. The knowledge base contains the heuristic rules for the design of passive solar buildings. Whenever possible, the knowledge base guides the designer through the decision making process. Yet, if the rules of thumb are not acceptable for the particular design problem, the KB-CAAD system guides the architect by using a procedural simulation model. We demonstrate by means of a case study, that not only does the KB-CAAD system lead to the design of better solar buildings, but that this process requires less time and labor than the process of building presentations by means of standard available CAAD systems.

source Building and Environment. England: Pergamon Press Ltd., 1978. vol. 13: pp. 109-123 : ill., diagrams. includes bibliography and appendix. h)0*0*0* Ԍ A model for decomposition of a multi-cell system into maximum intraconnected subsystems, and their recomposition in a hierarchical way, was developed. The system is presented as a graph, the vertices of which are the elements and the links are the relations between them. The algorithm for the decomposition is based on successive 'splitting' of the system into subsystems, by applying the minimal cut procedure
summary The recomposition is carried on by repeating the same decomposition technique on a graph, in which the vertices are the clusters that were obtained as final output of the decomposition process. Various constraints, like the size of the subsystems can be incorporated in the algorithm

title Decomposition of a Multi-Cell Complex -- A Problem in Physical Design
source November, 1974. 8 p. : ill., diagrams. includes bibliography
summary A method for decomposition of a multi-cell complex is suggested. The algorithm is based on successive splitting steps. At each step the set of elements is subdivided into at least two subgroups. The decomposition is carried out by translating the incidence matrix into a directed network and then applying a minimum-cut algorithm for finding the optimum cut-set. Various architectural constraints are incorporated in the decomposition algorithm. An example of an elementary school design problem is given to illustrate the suggested algorithm

summary A method for the design of fixed and movable external sunshaeds for windows is presented. The window can have any shape and be located on a wall having an arbitrary orientation. The fundamental idea is to use a computer to generate the entire envelope of the family of shading solutions that satisfies a prescribed set of shading requirements. The envelope of solutions serves as a nomogram on the basis of which sunshades are designed. Any sunshade designed following this nomogram satisfies the prescribed demands. The method creates an unlimited space of solutions, leaving the final design to the architect's imagination

title Climate and Building Design - Tradition, Research and Design Tools
source Energy and Buildings. 1984. vol. 7: pp.55-69 : ill. tables. includes bibliography
summary Important design parameters that influence the building thermal behavior and in particular natural cooling are discussed. Among these design parameters are: ventilation, evaporation, proper shading, orientation of the building and its proportions with respect to the orientation, the color of the building's envelope and its conductivity, the thermal mass of the building, night radiation to the sky and the stack effect. The latter is the katabatic and anabatic cooling. Different design tools aimed at the study of the influence of the climatological parameters on the form and h)0*0*0* Ԍ characteristics of buildings were developed in recent years. These tools help architects in designing houses with improved indoor thermal conditions without mechanical means, or with minimum energy consumptions. Several design tools, as well as design considerations and traditional constructions, are presented

title Layout Design Problems: Systematic Approaches
source Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 28-52
summary The complexity of the layout design problems known as the 'spatial allocation problems' gave rise to several approaches, which can be generally classified into two main streams. The first attempts to use the computer to generate solutions of the building layout, while in the second, computers are used only to evaluate manually generated solutions. In both classes the generation or evaluation of the layout are performed systematically. Computer algorithms for 'spatial allocation problems' first appeared more than twenty-five years ago (Koopmans, 1957). From 1957 to 1970 over thirty different programs were developed for generating the floor plan layout automatically, as is summarized in CAP-Computer Architecture Program, Vol. 2 (Stewart et al., 1970). It seems that any architect who entered the area of CAAD felt that it was his responsibility to find a solution to this prime architectural problem. Most of the programs were developed for batch processing, and were run on a mainframe without any sophisticated input/output devices. It is interesting to mention that, because of the lack of these sophisticated input/output devices, early researchers used the approach of automatic generation of optimal or quasioptimal layout solution under given constraints. Gradually, we find a recession and slowdown in the development of computer programs for generation of layout solutions. With the improvement of interactive input/output devices and user interfaces, the inclination today is to develop integrated systems in which the architectural solution is obtained manually by the architect and is introduced to the computer for the appraisal of the designer's layout solution (Maver, 1977). The manmachine integrative systems could work well, but it seems that in most of the integrated systems today, and in the commercial ones in particular, there is no route to any appraisal technique of the layout problem. Without any evaluation techniques in commercial integrated systems it seems that the geometrical database exists Just to create working drawings and sometimes also perspectives.

summary This work illustrates the use of solid modeling for the representation and analysis of complex architectural structures and details. While the approach is a general one it is demonstrated and implemented on the visual representation and evaluation of Mediaeval Age basilican structures. Basilican structures have the advantage that rules of composition for defining their form are well formulated. These rules are imposed on the solid modeler as high hierarchy architectural language (HHALL). It is within this language that the basilican structures are described and analyzed.

summary A method for the design of communities with solar access to each building is presented. The method allows the determination of the minimum possible distance between the buildings that enables insolation, the maximum height allowed for a given building without violating the "Solar Rights" of its neighbors, and how low the window or the passive solar collector can be placed on the wall and still be insolated in winter. The fundamental idea is to use a computer and CRT to generate the entire envelope of the families of design solutions. These solutions provide the required open space between buildings to sustain the "Solar Rights" of the building under consideration. This envelope of solutions serves as a nomogram on the basis of which the location of each building in the solar communities is determined. The method creates an unlimited space of solutions, leaving the final design to the architect's imagination.

source CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] Mnchen (Germany), 4-6 August 1997, pp. 317-330
summary This work discusses the structure of knowledge base CAAD systems for the design of solar and low energy buildings, along with the presentation of the different knowledge bases required for such systems. The general discussion is followed by presenting a KBCAAD system PASYS, that was developed as a tool for determining thermal comfort design strategies in the pre-conceptual design stage. PASYS is based on a knowledge base which stores the existing information concerning thermal comfort rules of thumb and accurate procedural calculations, which facilitates defining thermal comfort design strategies that suite best the local climatic conditions and the specific constrains of the design problem at hand.
