title	A Knowledge Based Computer- Aided Solar Design System

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	A digital Procedure of Building Construction: A practical project
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	From type to network: a review of knowledge representation methods in architecture intelligence design
doi	https://doi.org/https://doi.org/10.1007/s44223-022-00006-9
source	Architectural Intelligence Journal
summary	With the rise of the next generation of artificial intelligence driven by knowledge and data, the research on knowledge representation in architecture is also receiving widespread attention from the academia. This paper sorts out the evolution of architectural knowledge representation methods in the history of architecture, and summarizes three progressive representation frameworks of their development with type, pattern and network. By searching these three keywords in the Web of Science Core Collection among 4867 publications from 1990 to 2021, the number of publications in the past 5 years raised more than 50%, which show significant research interest in architecture industry in recent years. Among them, the first two are static declarative knowledge representation methods, while the network-based knowledge representation method also includes procedural knowledge representation methods and provides a way for knowledge association. This means the network representation has more advantage in terms of the logical completeness of knowledge representation, and accounts for 67% of the current research on knowledge representation in architecture. In the context of the rapid development of artificial intelligence, this method can realize the construction of architectural knowledge system and greatly improve the work efficiency of the building industry. On the other hand, in the face of carbon-neutral sustainable development scenarios, using knowledge representation, building performance knowledge and design knowledge could be expressed in a unified manner, and a personalized and efficient workflow for performance-oriented scheme design and optimization would be achieved.

title	Considering Energy, Materials and Health Factors in Architectural Design, Two Renovation Strategies for the Portuguese Building Stock
doi	https://doi.org/10.52842/conf.caadria.2022.2.619
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 619-628
summary	According to the Intergovernmental Panel on Climate Change, the built environment has a significant share in global final energy use, greenhouse gases emission, land-system change, and biodiversity loss to list some indicators. In Europe, the biggest challenge is to regenerate existing building stock to create a positive impact on Nature. The Portuguese housing stock is old: 56% is more than 30 years old, and it has a low level of thermal comfort and energy efficiency. The first thermal regulations appeared in 1990 and therefore most of the houses need urgent renovation to meet EU decarbonization goals, and to improve energy efficiency, as well as well-being and comfort of residents. This paper presents a method that aims to verify existing solutions known from vernacular architecture as complementary to existing strategies. It employs digital simulation to verify whether they could be used for renovation, measuring their impact on human and planetary health. The paper shows that there is a wide spectrum of parameters that influence the renovation process and that it is possible to enhance building performance using vernacular knowledge.

title	Information Modeling Applied to Cost and Energy Analysis During the Early Stages of Building Design
source	International Conference Proceedings on Systems Research (5th. : 1990 ). [6] p. : ill. includes bibliography
summary	The evaluation of design solutions by computer can only be achieved if the information describing the building design is in a form accessible by the computer. This not only demands that the data is in a machine-readable form, but that the data is logically organized, classified, and grouped so that its 'knowledge' can be found, extracted, used and modified by the variety of external sources. The article presents applications of information modeling to the design of knowledge bases to support design cost control and energy analysis

summary	Analogous to music sampling, in which sounds from the environment are recorded, distorted and used in unique ways to create music, "image sampling" is the visual equivalent of a sound bite used to create new visual forms, textures, patterns and types of architecture. Through the use of image sam ling, a designer can accurately record and digitize images from the existing visual world: rom the physical (built or natural) context of the site, from history (a specific building " or a significant architectural monument) or from previous work produced by the designer. The digital scanning process makes design information equal and uniform, as it converts all images to dot patterns of varying color. As a result the image can be transformed through numeric operations (even when the algorithms are transparent to the end user). The recorded images can therefore be fragmented, combined, distorted, duplicated, tweened, or subjected to random automated operations. Because computer images are digital, they facilitate modification and transformation, unlike their analog counterparts. Merging video and image processing capabilities with three-dimensional modeling permits the designer to collage visual information into new and readily editable architectural proposals. Combining image samples into new architectural concepts expands the scope of potentials available to the architect and also raises fundamental questions about issues of originality, creativity, authenticity, and the nature of the design process itself. What is original work, created by the designer, and what is merely re-used? The discussion of new digital imaging eventually leads to questions about design theory and ethics, in addition to those associated with computer technology and architectural form. As one works in any new medium, including the digital environment, many questions are raised about its impacts on design. Much of what is presented in this paper are early speculations on the implications of the digital technology and its influence on architecture.

title	A Hypermedia Model for Supporting Energy Design in Buildings
doi	https://doi.org/10.52842/conf.acadia.1994.039
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 39-49
summary	Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

title	Adaptive Mesh Generation for Global Diffuse Illumination
source	Computer Graphics Proc. SIGGRAPH 90 Vol. 24, No. 4, Aug. 1990, pp. 155-164
summary	Rapid developments in the design of algorithms for rendering globally illuminated scenes have taken place in the past five years. Net energy methods such as the hemicube and other radiosity algorithms have become very effective a t computing the energy balance for scenes containing diffusely reflecting objects. Such methods first break up a scene description into a relatively large number of elements, or possibly sev- eral levels of elements. Energy transfers among these ele- ments are then determined using a variety of means. While much progress has been made in the design of energy transfer algorithms, little or no attention has been paid to the proper generation of the mesh of surface elements. This pa- per presents a technique for adaptively creating a mesh of surface elements as the energy transfers are computed. The method allows large numbers of small elements to be placed at parts of the scene where the most active energy trans- fers occur without requiring that other parts of the scene be needlessly subdivided to the same degree. As a result, the computational effort in the energy transfer computations can be concentrated where it has the most effect.

title	Knowledge Based Interpretation of Architectural Drawings
source	Massachusetts Institute of Technology, Department of Civil Engineering, Cambridge, MA
summary	Architectural schematic drawings have been used to communicate building designs for centuries. The symbolic language used in these drawings efficiently represents much of the intricacy of the building process (e.g. implied business relationships, common building practice, and properties of construction materials). The drawing language is an accepted standard representation for building design, something that modern data languages have failed to achieve. In fact, the lack of an accepted standard electronic representation has hampered efforts at computer intergration and perhaps worsened industry fragmentation. In general, drawings must be interpreted, by a professional, and then reentered in order to transfer them from one CAD system to another. This work develops a method for machine interpretation of architectural (or other) schematic drawings. The central problem is to build an efficient drawing parser (i.e. a program that identifies the semantic entitites, characteristics, and relationships that are represented in the drawing). The parser is built from specifications of the drawing grammar and an underlying spatial model. The grammar describes what to look for, and the spatial model enables the parser to find it quickly. Coupled with existing optical recognition technology, this technique enables the use of drawings directly as: (1) a database to drive various AEC applications, (2) a communication protocol to integrate CAD systems, (3) a traditional user interface.

title	Vector Field Representation for the Evaluation of Multiple Performance Variables
source	1990. 6, [7] p., [3] p. of ill. includes bibliography
summary	A vector field representation is proposed to simulate the spatial distribution of four building system performance variables: light, sound, radiant heat, and air flow. From this simulation, a measure of the impact of adding, deleting, or modifying an object in the field is computed. This measure serves as a passive evaluation of the user/designer's decision to modify the location or dimensions of the object in a space. This process of simulation-evaluation is performed by a performance module (PM), which is viewed as a component of a CAAD System (Computer Architectural Aided Design). This paper describes the motivation, objectives, methodology and preliminary results of the approach

title	SEED: A Software Environment to Support the Early Phases in Building Design
source	Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary	The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

title	Design Decision Making Using Pareto-Optimal Dynamic Programming
source	Berlin: Springer- Verlag, 1990. pp. 376-396
summary	When designing using the systems approach, the given system is decomposed into a number of subsystems, and for each subsystem a set of feasible alternatives is selected by the designer. A building design example is presented in which it is demonstrated that sufficient relevant solutions are generated in one pass of the dynamic programming procedure to give a good approximation to the Pareto set, thus offering designers sufficient choice in making a final selection. The relevant information is displayed in an intelligent manner so that designers can either make a final decision or else perceive what extra information they require

summary	In Lund the full-scale laboratory is mainly used as a tool for citizen or user participation. Our intention is to develop the full-scale method further for this purpose. For several years now, we have carried through projects together with different users - mainly people from various types of working-places but recently also with dwellers. Most of our work has been financed by our clients, i.e. private enterprises, trade unions, county councils or municipalities, but since this summer we also receive support from the Swedish Council for Building Research. We have worked with many types of environments and their specific problems, but thanks to the research money we will now have an opportunity to develop our method in a more conscious manner. The purpose of our research is to increase the awareness of the different mechanisms involved in the participant/user process. We want to improve and refine our method and evaluate its advantages and disadvantages compared to other media for spatial communication. In our research program we will now present some criteria that have developed from our previous experiences and which we find essential to our future work.

title	Design Problems and Evaluative Strategies Using CAAD
source	February, 1990. 16 p. : col. ill. includes bibliography
summary	The way architects design comes into sharp focus when developing strategies for evaluating buildings. Architectural design is a highly subjective activity on the one hand but on the other it is also highly objective. The paper examines the use of CAAD systems for objective evaluation while also recognizing that this kind of evaluation has to be related to the subjective aspects of the design. In order to examine this, further research has been carried out into the use of CAAD systems to evaluate sunshading characteristics in a building design problem. The approach utilized the Integraph AMOD software to generate three dimensional models of the design proposal which were then tested using the Integraph Model View software which has a sunshading facility. The utility of this approach was tested first against criteria of how accurate the computer was in giving meaningful feedback to the designer. Secondly, how productive this approach was in the design process as compared to traditional techniques using instruments such as the heliodon. Finally, a discussion of the developments of the approach is given

summary	This book is both an introduction to economic principles and theories as they relate to building design decisions, and a practical reference guide on how to use economic principles when making decisions. It unites a variety of specialized topics relating to building economics, such as cost estimating, life-cycle costing, cost indexes, capital budgeting, decision analysis, and real estate feasibility analysis, developing them within the framework of an integrated approach to making building design and management decisions. This integrated approach is developed by adapting basic approaches of decision theory to economic evaluation. This book attempts to achieve a sensible balance between the need to simplify relatively complex economic and decision theory principles and practices without sacrificing the intellectual content of the material

title	A Case Study in Knowledge-Based System Development : Envelope Design for Reduction of Traffic Noise Transmission
source	February, 1990. 19 p. : some ill. and table. includes a bibliography
summary	Researchers have demonstrated the value of replication of research and explicit testing of concepts in artificial intelligence (Ritchie and Hanna 1989). In this study, a rule- based system was implemented as an exercise in the application of the theory and practice of knowledge-based systems development to architectural design analysis. The test domain was the selection of wall and window assemblies to provide adequate noise reduction given a set of traffic and building site conditions. This domain was chosen for two reasons: (1) considerable detailed heuristic information was available; and (2) it avoided large solutions spaces, 'errorful' and time-dependent data, and unreliable knowledge. Development of the system in conjunction with an extensive literature review revealed that publications on construction and performance of rule-based systems provided insufficient detail on key aspects of system architecture. Topics suffering from neglect or insufficiently rigorous treatment included algorithms used in automated inference, methods for selection of inference procedures, the integration of numerical and symbolic processing, the formulation of explanation mechanisms to deal with integrated numerical and symbolic processing, testing methods, and software standardization. Improving the quality and scope of knowledge in these areas is essential if expert systems are to be applied effectively in architectural design

title	Towards a Genome for Zero Carbon Retrofit of UK Housing

source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 197–206
summary	The United Kingdom has some of the worst insulated housing stock in Northern Europe. This is in part due to the age of housing in the UK, with over 90% being built before 1990 [McCrone 2017, Piddington 2020]. Moreover, 85% of current UK housing will still be in use in 2050 by which stage their Government are targeting Net Carbon Zero [Eyre 2019]. Domestic energy use accounts for around 25% of UK carbon emissions. The UK will need to retrofit 20 million dwellings in order to meet this target. If this delivery were evenly spread, it would equate to over 2,000 retrofit completions each day. Government-funded initiatives are stimulating the market, with upwards of 60,000 social housing retrofits planned for 2023, but it is clear that a system must be developed to enable the design and implementation of housing-stock improvement at a large scale.This paper charts the 20-year development of a digital approach to the design for low-carbon domestic retrofit by architects Constructive Thinking Studio Limited and thence documents the emergence of a collaborative approach to retrofit patterns on a National scale. The author has led the Research and Development stream of this practice, developing a Building Information Modelling methodology and integrated Energy Modelling techniques to optimise design for housing retrofit [Georgiadou 2019, Ben 2020], and then inform a growing palette of details and a database of validated solutions [Moorhouse 2013] that can grow and be used to predict options for future projects [D’Angelo 2022]. The data is augmented by monitoring energy and environmental performance, enabling a growing body of knowledge that can be aligned with existing big data to simulate the benefits of nationwide stock improvement. The paper outlines incremental case studies and collaborative methods pivotal in developing this work The proposed outcome of the work is a Retrofit Genome that is available at a national level.
