title	Parametric Design of the Vela Roof
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 231-240
summary	Due to the increased request for representative structures and for spaces to be used independent of the weather conditions, contemporary cities increasingly integrate public covered spaces (shadowed squares and streets, courtyards, historic commercial galleries, etc.) in the urban fibre. Facing the design of large roof structures for semi outdoor spaces is increasingly common for architects and engineers. When focusing on large roofs, aesthetics, structural performance and economics often dominate the design process. However, the current increased emphasis on energy-related aspects generates new challenges. Particularly, the use of renewable energy resources needs to be confronted. In this paper we will address the subject through a case study whose design aimed at integrating performance evaluations in the very early stages of the process. The case study focuses on the so-called “Vela roof”. This roof is part of a larger project currently under construction in Bologna (Italy). The focus of the study concerns the use of on-site renewable climate (energy) resources with special attention given passive reduction of summer overheating and daylight. For these tasks a parametric model was developed to support the decision making process and the paper will present its potential with respect to performance-oriented design during the conceptual design phase of roof structure. The very first conceptual design developed by the architectural office was assumed as a starting point for the inclusion of performance criteria. In the preliminary design of the roof uncomfortable conditions were expected under the whole roof in the summer. Various strategies for improving the thermal comfort were investigated, involving a large set of combined systems. Not all of these will be detailed in this paper. Instead we will focus on the ones directly affected by the geometry of the roof. Those are mainly air flow for cooling and the reduction of solar gain, in combination with their effects on daylight. Their investigation was based on a chain of dependencies to be integrated in the design process. With respect to that, parametric modelling was used. Parametric modelling allows both geometrical entities and their relationships to be represented. These relationships are structured in a hierarchical chain of dependencies, established during the preliminary parameterization process. The independent properties of the model are usually expressed through independent parameters, and their variations generate different configurations of the model. By making use of this potential, three project scales were parametrically explored. At the large scale, parametric variations of the overall shape of the roof were investigated in relation to cooling through ventilation and here the parametric model allowed for the generation of both different configurations of the roof, including its structural morphology and variations of its structural tessellation. At the medium scale, the integration of openable modules was investigated in relation to air extraction for cooling; with respect to this, the parametric model allows exploring openings based on variations of size and distribution. At the small scale, various options were explored for the cladding system, in order to reduce the direct solar gain while still allowing the income of indirect natural light. The parametric model was used to investigate the configuration of self-shading modules and their integration in the structure. Specific emphasis will be given to the small scale. The advantages in design process and the current limits of the parametric modelling approach used here will be discussed in the paper.

summary	The paper addresses the design of large roof structures for semi outdoor spaces through an investigation of a type of performance-oriented design, which aims at integrating performance evaluations in the early stages of the design process. Particularly, aiming at improving daylight and thermal comfort under large structures, the paper focuses on the exploration of passive solar strategies to reduce the need for imported energies. Referring to this context, the potential of parametric modeling is investigated with respect to performance-oriented design and a method, denoted ParaGen, is presented, based on the integration of parametric modeling and genetic algorithms. The potentials of the method are shown by discussing a case study, the roof SolSt. The design process of SolSt is based on parametric variations of its curvature, the density of its modules and the geometry of its cladding and explored based on the daylight and solar exposure of the covered spaces.

title	Parametric Approach to the Bioclimatic Design of a Student Housing Building in Patras, Greece
doi	https://doi.org/10.52842/conf.ecaade.2010.313
source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.313-319
summary	A new housing complex on the Campus of the University of Patras, Greece, is expected to serve as a test-bed for experimentation with a parametric design process that integrates significant climatic data. To optimize the environmental performance of the proposed housing complex a parametric design algorithm has been developed. The algorithm links the weather data in the area with the site topography and the basic geometric features of the buildings on the site. To explore the interaction of the building features with the prevailing winds in the area and the solar exposure throughout the year various software applications, including computational fluid dynamics (CFD) simulations, have been utilized. The inclusion of wind data in the algorithm renders it particularly effective. The developed parametric process has been useful during the early design phase when studies on various patterns for arranging the buildings on the site were conducted. The parametric process has facilitated the configuration of the typical building block as well.

title	Non-Linear Architectural Design Process
source	International Journal of Architectural Computing vol. 8 - no. 1, 41-54
summary	The introduction of the computer to the architectural design process have facilitated the possibility to examine a large number of design alternatives by allowing continuous variation between pre defined constraints. However, for the most part, evaluation and comparison of the alternatives is still handled manually in a linear fashion by the designer. This paper introduces a different approach to the architectural design process, which calls for a multithreaded or a non-linear design process. In a non-linear design process design directions and alternatives are generated, presented and evaluated simultaneously, and in real time. As an example for a non-linear design process the Generative Performance Oriented Design model and software tool (GenPOD) are presented and discussed. Moving towards non-linear modes of design arguably increases design creativity by allowing generating and evaluating a greater number and variation of design alternatives.

summary	Nowadays, a large set of involved planning parties are heavily demanded with the definition of holistic in kind requirement specifications for urban planning sites – so called future cities. However, the resulting amountof specifications for a specific building project poses a great challenge to designers and planners especially when it comes to include this information into their design proposals for a sustainable urban development. These design performance criteria are traditionally expressed in textual and numerical planning guidelines and which are making it difficult to establish a comprehensive and holistic view onto the domain itself. Therefore we present in this paper a design guide visualization method to overcome this situation for the evaluation of design specification and urban layouts in a qualitative and quantitative manner.

title	Energy Performance Modeling of an Office Building and Its Evaluation – Post-Occupancy Evaluation and Energy Efficiency of the Building
doi	https://doi.org/10.52842/conf.caadria.2013.209
source	Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 209-218
summary	Energy performance modelling can provide insights into the efficiency and sustainability of commercial buildings, and also the achievement of certification standards such as USGBC LEED. However, the results from the modelling must be validated via a post-construction evaluation, which quantifies any discrepancies between the predicted energy usage and the actual energy consumed. In this study, an existing office building was examined to test how well the model predicts energy usage. The results from the model were compared with the actual usage of gas and electricity over two years (2010-2011). Our study showed a 123% higher gas usage,and a 36% lower electricity, compared with the simulation. This difference presents that occupant behaviour and building construction practices have significant impact on the energy usage of a building. For instance, the large discrepancy among gas usage is due to the office building’s thermal envelope, which identifies the spots at which heat leaks out of the building, thereby forcing the heating unit to work more. Additionally, the post occupancy evaluation study identified that indoor environmental conditions impact on energy consumption of the building.

title	FabPOD: An Open Design-to-Fabrication System
doi	https://doi.org/10.52842/conf.caadria.2013.251
source	Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 251-260
summary	Digital workflows from the design to the production of buildings have received significant recent attention in architectural research. The need for both integrated systems for design collaboration (Boeykens and Neuckermans, 2006) and clear and flexible communication flows for non-standard fabrication outcomes have been identified as fundamental (Scheurer, 2010). This paper reports on the development of a digital “design system” for the design and prototyping of an acoustic enclosure for meetings in a large open work environment, theFabPod. The aim was to keep this system open for temporal flexibility in as many aspects of the finalisation of the design as possible. The system provides novel examples of both integrated collaboration and clear communication flow. (1) Acoustics is included as a design driver in early stages through the connection of digital simulation tools with design models. (2) Bi-directional information flows and clear modularisation of workflow underpins the system from design through to fabrication and assembly of the enclosure. Following the completion and evaluation of the FabPod prototype, the openness of the system will be tested through its application in subsequent design and prototyping iterations. Design development will respond to performance testing through user engagement methods and acoustic measurement.

title	The Use of Digital 3-D Information to Assess Urban Environmental Quality Indicators
doi	https://doi.org/10.52842/conf.ecaade.2010.499
source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.499-506
summary	This paper anticipates the use of 3-D data for the environmental analysis of cities, aiming to provide useful tools for urban designers. The extraction of urban environmental quality (UEQ) indicators from 3-D information using innovative tools is presented. We will introduce our recent research about the implementation of computational tools for the analysis, evaluation and design of the urban space and compare results that can be obtained with different data sources. In particular, we are going to present the advantages of urban models generated from LiDAR data, by showing the case-study analysis of the measurement and quantification of urban vegetation indicators. Results show that the limitation to solar accessibility on roofs is not relevant for the case-study area. Moreover, a set of environmental and morphological indicators could inform urban designers for decision making processes about the distribution of vegetation inside the urban fabric.

title	Automated Cost Analysis of Concept Design BIM Models
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	Assessing the Use of Advanced Daylight Simulation Modelling Tools in Enhancing the Student Learning Experience
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 303-313
summary	In architecture schools, where the ‘studio culture’ lies at the heart of students’ learning, taught courses, particularly technology ones, are often seen as secondary or supplementary units. Successful delivery of such courses, where students can act effectively, be motivated and engaged, is a rather demanding task requiring careful planning and the use of various teaching styles. A recent challenge that faces architecture education today, and subsequently influences the way technology courses are being designed, is the growing trend in practice towards environmentally responsive design and the need for graduates with new skills in sustainable construction and urban ecology (HEFCE’s consultation document, 2005). This article presents the role of innovative simulation modelling tools in the enhancement of the student learning experience and professional development. Reference is made to a teaching practice that has recently been applied at Portsmouth School of Architecture in the United Kingdom and piloted at Deakin University in Australia. The work focuses on the structure and delivery of one of the two main technology units in the second year architecture programme that underwent two main phases of revision during the academic years 2009/10 and 2010/11. The article examines the inclusion of advanced daylight simulation modelling tools in the unit programme, and measures the effectiveness of enhancing its delivery as a key component of the curriculum on the student learning experience. A main objective of the work was to explain whether or not the introduction of a simulation modelling component, and the later improvement of its integration with the course programme and assessment, has contributed to a better learning experience and level of engagement. Student feedback and the grade distribution pattern over the last three academic years were collected and analyzed. The analysis of student feedback on the revised modelling component showed a positive influence on the learning experience and level of satisfaction and engagement. An improvement in student performance was also recorded over the last two academic years and following the implementation of new assessment design.

title	A Performance-Based Design Approach for Early Tall Building Form Development
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 39-50
summary	This paper presents a methodological interactive design approach within which structure is integrated into tall building form development. The approach establishes a synergy between generative and analytical tools to allow for parallel interaction of the formal and structural design considerations during the conceptual design phase. An integration of the associative modeling system, Grasshopper, and the structural analysis tool, ETABS was established, and a bi-directional feedback link between the two tools was initiated to guide the iterative from generation process. A design scenario is presented in this paper to demonstrate how the parametric generation and alteration of architectural form can be carried out based on instant feedback on the structural performance. Utilizing such a tool, architects can not only develop improved understanding of structural needs, but also realize their formal ideas structurally and materially.

summary	This paper reports on the computer process to be used in an ongoing research to investigate the effect of architectural parameters of tall buildings on the incorporation of wind turbines. The process combines a generative modeling tool (Grasshopper) and a performance based CFD tool (Virtualwind). The process is demonstrated on three typical tall building plan configurations. The wind speed was simulated at certain locations to demonstrate the ability of tall buildings to enhance the wind speed and thus maximize the energy produced by wind turbines located between twin towers. The process to predict wind power production is lastly listed.

summary	The following paper deals with a performance-driven morphogenetic design task to improve the conditions of room acoustics, using as a case study the material laboratory of the School of Architecture at Federico Santa Maria University of Technology. Combining contemporary Parametric Modeling techniques and a Performance- Based approach, an automatic generative system was produced. This system generated a modular acoustic ceiling based on Helmholtz Resonators. To satisfy sound absorption requirements, acoustic knowledge was embedded within the system. It iterates through a series of design sub-tasks from Acoustic Simulation to Digital Fabrication, searching for a suitable design solution. The internal algorithmic complexity of the design process has been explored through this case study. Although it is focused on an acoustic component, the proposed design methodology can influence other experiences in Parametric Design.

summary	This paper posits a design approach that integrates multi-agent generative algorithms and structural topology optimisation to design intricate, structurally efficient forms. The research proposes a connection between two dichotomous principles: architectural complexity and structural efficiency. Both multi-agent algorithms and Bi-directional evolutionary structural optimisation (BESO) (Huang and Xie 2010), are emerging techniques that have significant potential in the design of form and structure.This research proposes a structural behaviour feedback loop through encoding BESO structural rules within the logic of multi-agent algorithms. This hybridisation of topology optimisation and swarm intelligence, described here as SwarmBESO, is demonstrated through two simple structural models. The paper concludes by speculating on the potential of this approach for the design of intricate, complex structures and their potential realisation through additive manufacturing.

summary	As issues of sustainability gain traction for architects, methodologies for designing, analyzing, and calibrating design solutions have emerged as essential areas of research and development. A number of approaches have been pursued with regard to embedding data into the design process, most fall into one of two approaches to research. The first approach is to mediate environmental impact at the level of applied technology; the second alters building methods and material construction, generating efficient energy use. However, few approaches deal with the crafting of relationships between information and performance on an architectural level. We will examine an approach focused on understanding how crafting relationships between information and design can move architecture towards achieving sustainability. In developing this approach, we created a data-driven design methodology spanning from design inception to construction. Data-driven models, common in the fields of natural science, offer a method to generate and test a multiplicity of responsive solutions. By contextualizing the solutions generated, we were able design though a set of specific and controlled responses rather than as a singular solution. Information utilization requires a new kind of craft that moves beyond instances into relationships and offers performance sensitive issues in design a focused trajectory. We applied this method to the research and development of a responsive shading structure built in conjunction with a thermal testing lab for two test locations – Austin, Texas (Figure. 1 and 2) and Munich, Germany. The following paper chronicles the design and construction at the Texas site over an academic semester.

summary	The state university of Campinas, Unicamp, is a public university in upstate São Paulo, Brazil, ranked the second best in the country. It was founded in 1966, and its main campus started to be built in 1967, in the suburbs of Campinas, nowadays a two-million people city. The area of the campus is almost 3 million square meters (300 hectares), with a total built area of 522.000 m2 and a population of 40 thousand people - 30 thousand students, 2 thousand faculty members and almost 8 thousand staff members. The campus’ gross population density is 133 people per hectare. Less than 6% of the total campus area is presently occupied. The design of Unicamp's campus is based on concepts that were typical of the modern movement, with reminiscences of corbusian urbanism, in which preference is given to cars and buildings are spread apart on the territory, with little concern to the circulation of pedestrians. The standard building type that has been built on campus since the 1970's is based on non-recyclable materials, and has a poor thermal performance. Unicamp is expected to double its number of students by the year 2030. The campus density is thus expected to grow from 600 people per hectare to almost 1,000 people per hectare. The need to construct new buildings is seen as an opportunity to correct certain characteristics of the campus that are now seen as mistakes, according to sustainability principles. This paper describes a set of proposals targeting the increase of the campus' density in a sustainable way. The plan also aims at increasing the quality of life on campus and diminishing its impact on the environment. The main targets are: - Reducing the average temperature by 2oC; - Reducing the average displacement time by 15 minutes; - Increasing the campus' density by 100%; - Reducing the CO2 emissions by 50%. // In order to achieve these goals, the following actions have been proposed: Developing a new standard building for the university, incorporating sustainability issues, such as the use of renewable and/or recyclable materials, the installation of rainwater storage tanks, the use of natural ventilation for cooling, sitting the buildings in such a way to decrease thermal gain, and other issues that are required for sustainable buildings' international certifications. To assess the performance of the new standard building, different simulation software were used, such as CFD for checking ventilation, light simulation software to assess energy consumption, and so on. 1. Filling up under-utilized urban areas in the campus with new buildings, to make better use of unused infrastructure and decrease the distance between buildings. 2. Proposing new bicycle paths in and outside campus, and proposing changes in the existing bicycle path to improve its safety. 3. Developing a landscape design plan that aims at creating shaded pedestrian and bicycle passageways.

summary	The project Knitectonics aims at exploring digital fabrication systems that facilitate optimized, adaptive and specific integrated architectural solutions (Male-Alemany 2010). It is inspired by the beauty of nature systems with their inherent efficiency and performance. The research explored on-site fabrication of monocoques shells, integrating skin and structure along with services and infrastructure, using a simple household technique. It thus embodies a self organized micro system of textures and a macro system of structures. This paper elaborates how the numeric aspects of a textile technique were used, first to digitally imitate the process of assembly and further exploited to develop and visualize a novel fabrication system, based on material research and technical experimentation.

title	Innovative design solutions for contemporary Tou-Kung based on topological optimisation
doi	https://doi.org/https://doi.org/10.1007/s44223-023-00028-x
source	Architectural Intelligence Journal
summary	Tou-Kung, which is pronounced in Chinese and known as Bracket Set (Liang & Fairbank, A pictorial history of Chinese architecture, 1984), is a vital support component in the Chinese traditional wooden tectonic systems. It is located between the column and the beam and connects the eave and pillar, making the heavy roof extend out of the eaves longer. The development of Tou-Kung is entirely a microcosm of the development of ancient Chinese architecture; the aesthetic structure and Asian artistic temperament behind Tou-Kung make it gradually become the cultural and spiritual symbol of traditional Chinese architecture. In the contemporary era, inheriting and developing Tou-Kung has become an essential issue. Several architects have attempted to employ new materials and techniques to integrate the traditional Tou-Kung into modern architectural systems, such as the China Pavilion at the 2010 World Expo and Yusuhara Wooden Bridge Museum. This paper introduces the topological optimisation method bi-directional evolutionary structural optimisation (BESO) for form-finding. BESO method is one of the most popular topology optimisation methods widely employed in civil engineering and architecture. Through analyzing the development trend of Tou-Kung and mechanical structure, the authors integrate 2D and 3D optimisation methods and apply the hybrid methods to form-finding. Meanwhile, mortise and tenon joint used to create stable connections with components of Tou-Kung are retained. This research aims to design a new Tou-Kung corresponding to “structural performance-based aesthetics”. The workflow proposed in this paper is valuable for Architrave and other traditional building components.

title	Abstractions for information based design
source	International Journal of Architectural Computing vol. 8 - no. 3, pp. 233-256
summary	This paper discusses how live linkages between parametric geometry, structural analysis and optimization can be leveraged to explore an architectural massing from different perspectives of optimum assuming a set of cost and value characteristics. Broad performance measures such as program area, cladding surface and structural quantities were computed for each geometry variation and collected. Optimums from different perspectives (structure, developer, designer) were extracted for each height category and compared. To further inform and engage stakeholders, a variety of visualization and filtering techniques have been implemented. These new techniques and associated distillation of data aids the design team in understanding the design space. A script based approach towards geometry and data management has led to a shift towards active option evaluation and a more interactive approach to form exploration. A generic workflow for structural analysis, design and optimization has been implemented and this ability to engineer at a greater velocity will move the design profession towards a more collaborative and information based design environment.
