title	Towards a BIM-Based Energy Rating System
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 285–294

summary	Governments in Australia are faced with policy implementation that mandates higher energy efficient housing (Foran, Lenzen & Dey 2005). To this effect, the National Construction Code (NCC) 2013 stipulates the minimum energy performance for residential buildings as 114MJ/m2 per annum or 6 stars on an energy rating scale. Compliance with this minimum is mandatory but there are several methods through which residential buildings can be rated to comply with the deemed to satisfy provisions outlined in the NCC. FirstRate5 is by far the most commonly used simulation software used in Victoria, Australia. Meanwhile, Building Information Modelling (BIM), using software such as ArchiCAD has gained a foothold in the industry. The energy simulation software within ArchiCAD, EcoDesigner, enables the reporting on the energy performance based on BIM elements that contain thermal information. This research is founded on a comparative study between FirstRate5 and EcoDesigner. Three building types were analysed and compared. The comparison finds significant differences between simulations, being, measured areas, thermal loads and potentially serious shortcomings within FirstRate5, that are discussed along with the future potential of a fully BIM-integrated model for energy rating certification in Victoria.

summary	Daylight is a crucial element for indoor environment quality. Office buildings commonly use fully glazed façades to reflect a luxurious appearance and to maximize natural light at the expenses of high energy consumption due to cooling/heating. Double-skin façades are one of the solutions that improve the building efficiency while maintaining good natural lighting. This paper studies the impact of various perforated outer skins for non-sealed double-skin facades on light quality in prototypical office space in Egypt using parametric design. A traditional solution for light such as the Mashrabiya is taken as an inspiration for this study to generate different forms of perforated screens. The cases were analysed using light simulation tool and sorted by a genetic algorithm to show best 30 solutions offered by the design criteria. A methodology to achieve these objectives was suggested in this paper to reach better light quality in indoor spaces.

title	Computing Level of Privacy in a Virtual Environment
source	International Journal of Architectural Computing vol. 11 - no. 1, 65-86
summary	This paper presents a computational model designed to analyze architectural space and to a develop privacy level using two methods: visual distance method and viewing angle method as those are primary cognitive mechanism to experience architectural space.We suggest that the result will offer possibilities for quantitative design analysis of privacy that influenced by architectural elements.The proposed method consists of two stages: determination of subdivided enclosed spaces and measuring privacy level on each subdivided enclosed space. Previous models showed that spatial quality is related to the visual distance to the architectural elements. In addition to distance variables, our model includes viewing angle variables to determine area and the direction angle from any observation point to the architectural elements on the boundary of an interior space.The case study evaluation is able to rank the quality of design of interior spaces with respect to their privacy level.

summary	This paper presents the results of research and development of Building Energy Simulation (BES) visualization methods. In this effort the authors used Building Information Modeling (BIM) Authoring Tools’ Application Programming Interface (API) to visualize BES results in BIM. We also used an external database to store and manage the object-based simulation results from a BES tool. Based on these methods, we created a prototype: Building Energy Performance Visualization (BEPV), which translates information from the result database to the Energy Performance Indicator (EPI) parameter in BIM. Using the prototype, when BIM models are created for building design, the building energy performance can be expressed visually as color-coding on the BIM, allowing users to see energy flows directly. The developed prototype lets architects use BIM as a common user interface for building design and performance visualization, and may improve their designs in early stages.

summary	This paper aims to investigate the potential of both open source software and new media (esp. computer vision and augmented reality) as tools for architectural design and education. The examples illustrated in the paper would be drawn mainly from students’ projects done as part of their AA Media Studies Course submission at the AA School of Architecture (AA) during the academic years from 2011/2012 to 2012/2013. The paper outlines the main approaches, which students have chosen to implement, both directly and indirectly, these new media and tools into their studio work at the AA. Section 1 briefly introduces a range of currently available open source computational design toolkits that are deemed useful for quick implementation of computer vision and augmented reality technologies. The related programming languages, softwares and hardwares would also be introduced and described accordingly. Sections 2 and 3 are accompanied with a visual catalogue of students’ projects to better illustrate the diversity in the understanding and implementation of computer vision and augmented reality technologies in architectural design. Section 4 serves to conclude the paper by first discussing briefly the feedback from students at the end of the course before clarifying the context of the research and thus its relation to recent work done by others using similar technologies.

title	Using Computational Fluid Dynamics to Assess Natural Airflow in a Prototype House-Interior
source	SIGraDi 2013 [Proceedings of the 17th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Chile - Valparaíso 20 - 22 November 2013, pp. 373 - 377
summary	This paper presents an airflow study with Computational Fluid Dynamic (CFD) software that was used to model the natural ventilation attributes at the interior of a prototype house. This study informed the design development phase of the house and guided the design of a dynamic curtain wall involving a matrix of 3 x 9 openable windows for its south façade. Alternative ways of modeling the building geometry were employed and different possible states of the house were examined to determine how change in the orientation and the basic dimensions of the envelope, and modifications in the number, distribution and angle of the open windows affect natural ventilation.

title	Geelong Digital Outdoor Museum (GDOM) - Photogrammetry as the Surface for a Portable Museum
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. 677-686
doi	https://doi.org/10.52842/conf.caadria.2022.1.677
summary	This paper presents the development and evaluation of the Geelong Digital Outdoor Museum (GDOM) prototype accessible at https://gdom.mindlab.cloud. GDOM is a portable museum‚our novel adaptation of the distributed museum model (Stuedahl & Lowe, 2013) which uses mobile devices to present museum collections attached to physical sites. Our prototype defines a way for intangible heritage associated with tangible landscapes to be accessible via personal digital devices using 360 3D scanned digital replicas of physical landscapes (photogrammetric digital models). Our work aligns with efforts set out in the UN Sustainable Development Goal 11 (SDG 11) to safeguard cultural and natural heritage, by openly disseminating the heritage of physical sites seamlessly through the landscape. Using a research by design methodology we delivered our prototype as a modular web-based platform that leveraged the Matterport digital model platform. We qualitatively evaluated the prototype's usability and future development opportunities with 32 front-end users and 13 potential stakeholders. We received a wide gamut of responses that included: users feeling empowered by the greater accessibility, users finding a welcome common ground with comparable physical experiences, and users and potential stakeholders seeing the potential to re-create physical world experiences with modifications to the digital model along with on-site activation. Our potential stakeholders suggested ways in which GDOM could be integrated into the arts, education, and tourism to widen its utility and applicability. In future we see design potential in breaking out of the static presentation of the digital model and expanding our portable museum experience to work on-site as a complement to the remote experience. However, we recognise the way in which on-site activation integrate into users' typical activities can be tangential (McGookin et al., 2019) and this would necessitate further investigation into how to best integrate the experience on-site.

summary	Assimilating Interactive Technology into Architectural Design – A Quest for developing an ‘Architectural Drawing’ for Urban Interaction Design as a Communication Platform Through Combining Physical Sensing Devices with Simulation Software The research presented in this paper investigates the need for an equivalent of architectural drawings for urban interaction design in an architectural scale in order to communicate interaction design intentions to design participants and clients through using state of the art computer, gaming and sensor technologies. The paper discusses two projects (a) Blur Building, as a large scale interaction design project executed through an experienced team and (b) presents as student design project coordinated by the researchers as a reference project. Both projects in this paper are discussed and evaluated from an Urban Interaction Design point of view. This paper emphasizes the significance for establishing ‘drawing’ equivalents for urban interaction design, discussing representation of ideas in architectural design; followed by outlining existing methods of interactive design representation, such as storyboards to then introduce current advancements in gaming environments. The following paper introduces a framework for future research projects that will design, deploy and evaluate of prototypes as a communication platform combining physical sensing devices in combination with gaming engines to enable a digital / physical hybrid. This would allow designers and clients to test, evaluate and improve urban interactions in a design phase prior to completing the project.

title	Knowledge-based methodology for architectural robotics fabrication. Real time impact assessment through a process flow analysis software
source	FUTURE TRADITIONS [1st eCAADe Regional International Workshop Proceedings / ISBN 978-989-8527-03-5], University of Porto, Faculty of Architecture (Portugal), 4-5 April 2013, pp. 229-236
summary	The main goal of the project is to generate a framework for a knowledge-based-methodology (KBM) within a parametric software. This is accomplished through a combination of the design software and robot simulation with real-time assessment based on a process-flow-diagram (PFD) structure that compiles the main environmental parameters of the manufacture process. The intention is to create a methodology to directly report the impact of the manufacture of a specific design, from the materials embodied energy to the energy consumption of each step. This framework provides valuable information which may monitor the developer towards alterations to increase the CAD/CAM performance. In the context of this paper, this methodology was applied in the conceptual design and manufacture of a housing structural insulated panel prototype using parametric design software and robotic equipment. The purpose is to generate a quasi-automated design process linked with real-time analysis and assessment of the fabrication process, offering real time environmental and cost analysis of a panelized structure house manufacture logic. The suggested methodology outputs information to compare and optimize the manufacture outline, and supports the screening and assortment of appropriate tool paths or combination of fabrication tools based on environmental/cost data, user-specified requirements and context characteristics.

summary	The creation of an algorithm that will allow the quantitative accuracy of inputs, related to the Brazilian reality, inside the BIM platform will cause a decrease of the public costs of work. However, in this article only focus on how you can modify internally the BIM system platform for achieving the quantitative goals in planning materials. The new tool of construction planning and scheduling when using BIM systems's contribution, through the external database, will provide the construction control based on composition of inputs along the time that will allow a more economical execution to ensure the efficiency of public buildings.

summary	While the methods for capturing the negative effects of density (e.g. congestion, friction) are widely understood and operationalized, capturing the positive effects of density (e.g. vibrancy, walkability) remain poorly explored. This research focuses on the latter, proposing a novel spatial analysis and mapping approach that can be used to capture the intensity of urban environments. We distinguish between urban density and intensity. Whereas density refers to the amount of people or elements of urban form (e.g. dwelling units, floor area) per unit area of land, intensity refers to the concentration of commercial and service activities on the ground floors along city streets. Bridging morphological mapping techniques with recent network analysis in GIS, ten metrics that capture specific attributes of the built environment influential to intensity are introduced and implemented using data collected from detailed field surveys within two comparative districts in the Bugis area of Singapore. A discussion of the efficacy of these metrics for urban design concludes the paper.

summary	Predicting future users’ behaviour and their activities in a building is a highly complex task that designers have to face during the design process. Despite its importance, few methods exist that can predict and help evaluate this type of building performance during the design process itself. Simulative approaches are gradually overcoming this shortcoming, but at present their application is limited to the representation of specific occurrences and behavioural performance aspects, such as emergency egress. Based on current developments in the video game industry, our research aims to establish a new approach to human behaviour simulation in built environments, based on a clear and reliable representation of the use processes occurring in a building. At its core is simulation based on the notion of events, defined as active entities on their own, comprised of space, people, and activities. These events entities are structured into collections called narratives, which represent and allow the simulation of the step-by-step performing of activities by users in a built environment.

summary	Performance based design systems are characterised through the use of performance related evaluation methods or by providing design environments which are restricting the design space according to performance criteria. The performance of a design can be evaluated by numerical simulations. With the use of numerical simulations a fundamental dilemma appears: the precision implied in numerical simulations and the imprecision of the design process itself are systematic contradictions. User control or user interaction in open systems places the user into charge of the imprecision required by the design process. In closed systems, as the below described evolutionary system, methods of imprecision have to be integrated i.e. into the precise simulation based evaluation procedure. Through tolerant selection methods and the gradual evaluation of individuals the rigid and precise system can be guided towards a design system rather than an optimisation system. Due to technical requirements which are related both to the fact of using computer systems but also to the systematic conditions implied to simulations the use of the tolerant selection methods is limited.

title	Symmetry Fields of Palladian Villas

summary	In this paper we present the idea of symmetry fields and an analysis of them on Palladian villas. Symmetry fields describe the symmetry related to the localized experiential view of an individual. We propose that the amount of symmetry, whether it be reflective, rotational, or translational, can be computed along with several other measures of visual aesthetic. While many buildings are designed using symmetry about the plan, and are represented using a plan view, it is only accessible to the designer and cannot actually be experienced in the real world. The local symmetries produced are drastically different than those planned.

title	Adaptive [skins]: Responsive building skin systems based on tensegrity principles
source	FUTURE TRADITIONS [1st eCAADe Regional International Workshop Proceedings / ISBN 978-989-8527-03-5], University of Porto, Faculty of Architecture (Portugal), 4-5 April 2013, pp. 155-170
summary	The project investigates responsive building skin systems that adapt to the dynamic environmental conditions to regulate the internal conditions in a habitable space over different periods of time by exhibiting a state of motion and dynamism. Heat and Light are the primary parameters for regulation, leading to energy efficiency and dynamic spatial effects. Passive and active skins using shape memory alloys and pneumatic actuators are developed through investigations of smart systems that integrate smart materials and smart geometries. The precedents in this domain have rarely dealt with individually controlled multiple parameters of heat and light in a single system, which is attempted in this project. Owing to the complexity of the multi-parametric system, genetic algorithms are developed for system optimization and calibrated with physical prototypes at varied scales. The developed systems are tested against two distinct climatic models- New Delhi and Barcelona, and evaluated for performance, based on heat and light, which are quantified as solar gain and illuminance as principles, and daylight factor for evaluation purpose. The use of genetic algorithms makes the problem solving faster and accurate. New tool-sets are developed in the process by combining various digital tools, to create a real-time feedback and memory loop system.

summary	This research aimed to explore the energy savings through the use of smart control as well as ceiling fan in intelligent building. As the energy consumption of air-conditioning (AC) accounts for about 40% of total residential energy, therefore, applying smart control system to the use of AC to achieve the effects of comfy and energy savings should be able to generate positive effect for the energy consumption of overall residential. This study used the smart control system in the intelligent building lab to transmit message to AC for its implementation of next operating step through the indoor temperature sensor in order to achieve energy saving effect.

title	Toward a Computational Approach of Creativity Assessment in Product Design

summary	One of the most important criteria for the performance quality in design is the creativity of the design. Many researchers have developed methods to assess the creativity of product design, but the subjective and qualitative judgments of traditional creativity measurement are proved to lack sufficient validity and reliability. Furthermore, most of the assessment of creativity in design is based on the design outcome instead of the design process. In this paper, we proposed a computational approach of creativity assessment in product design via the combination of the design process and design creativity. We established a method to quantify the design process. And design creativity is rated using the Consensual Assessment Technique. Then the correlation of all the creativity-related factors in the design process and the design creativity will be calculated. Last, creativity assessment formula is proposed based on the factors and the correlation coefficient.

title	Reconfigurable Formwork System for Vision-Informed Conformal Robotic 3D Printing

summary	Robotic additive manufacturing has garnered significant research and development interest due to its transformative potential in architecture, engineering, and construction as a cost-effective, material-efficient, and energy-saving fabrication method. However, despite its potential, conventional approaches heavily depend on meticulously optimized work environments, as robotic arms possess limited information regarding their immediate surroundings (Bechthold, 2010; Bechthold & King, 2013). Furthermore, such approaches are often restricted to planar build surfaces and slicing algorithms due to computational and physical practicality, which consequently limits the feasibility of robotic solutions in scenarios involving complex geometries and materials. Building on previous work (Çapunaman et al., 2022), this research investigates conformal 3D printing of clay using a 6 degrees-of-freedom robot arm and a vision-based sensing framework on parametrically reconfigurable tensile hyperbolic paraboloid (hypar) formwork. In this paper, we present the implementation details of the formwork system, share findings from preliminary testing of the proposed workflow, and demonstrate application feasibility through a design exercise that aims to fabricate unique components for a poly-hypar surface structure. The formwork system also offers parametric control over generating complex, non-planar tensile surfaces to be printed on. Within the scope of this workflow, the vision-based sensing framework is employed to generate a digital twin informing iterative tuning of the formwork geometry and conformal toolpath planning on scanned geometries. Additionally, we utilized the augmented fabrication framework to observe and analyze deformations in the printed clay body that occurs during air drying. The proposed workflow, in conjunction with the vision-based sensing framework and the reconfigurable formwork, aims to minimize time and material waste in custom formwork fabrication and printing support materials for complex geometric panels and shell structures.

summary	This paper presents an interdisciplinary work done at the Museum Oteiza near Pamplona, Spain during 2012 and 2013. The main goal is the use of low cost devices that allows natural interaction, Virtual and Augmented Realities to get the general public closer to the works and concepts of Oteiza through interactive serious games. The most difficult Oteiza’s concepts to understand are those related with the empty space or with time & space. We propose three different activities, shaped as serious game, that use the whole body to interact and play with these concepts. The result is a facility that has been installed at the entrance of the Museum and that can be used for free, before or after a visit to the museum. These activities were presented to 4 experts in Oteiza and the results are discussed. In addition, we gathered more comments after several groups of children tried the application in the museum.

title	Parametric urbanism as digital methodology. An urban plan in Beijing
source	FUTURE TRADITIONS [1st eCAADe Regional International Workshop Proceedings / ISBN 978-989-8527-03-5], University of Porto, Faculty of Architecture (Portugal), 4-5 April 2013, pp. 121-132
summary	Evolution and innovation in architecture are intensely related to the rise and developments of technology. Within this context, it is possible to recognize how in recent decades this milieu has fostered the development of new methodologies for urban design and architectural practice, as is, for example, the Parameterization. This paper is focused on the subject of Parametric Urbanism: discussing / questioning the emergence of this new architectural methodology; addressing the factors that contributed to its appearance; and seeking to understand whether the parametric approach has benefits and whether it may or may not be a solution or of assistance to urban planning. The paper provides a brief literature review focused on parametric urbanism and then it presents a practical case study of parametric urbanism: an Urban Plan in Beijing, developed in an academic context, at the University École Polytechnique Fédérale de Lausanne in 2012. Having as base diverse examples of parametric urbanism, it is tried to identify/justify decisions defining principles and application guidance for this project. The conclusion presents the final considerations based on opposing the case study with the theoretical approach, seeking to clarify whether this new kind of urban design methodology, Parametric Urbanism, is or not viable.
