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	This study is concerned with the building thermal performance education in the context of computer application. The project contains the original script coded in Maxscript for use in Autodesk 3ds Max. The tool workflow and functionality focus on the thermal calculations connected with sculpturing manipulation of architectural volume in pre-conception project stages, when detailed project solutions are undefined. The algorithm is based on the manual methods included in the curriculum. The paper also presents a study of software analyzing thermal performance as a justification for the script vision and educational implementation. The script is rather an addition than alternative for existing software, so it does not assume any resignation from more sophisticated products.

title	Energy Performance Modeling of an Office Building and Its Evaluation – Post-Occupancy Evaluation and Energy Efficiency of the Building

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.

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.

summary	The fusion between building assessment and design can lead to better informed design decisions. Performance oriented design is better supported through the use of interoperable file formats for data exchange between BIM and non-BIM tools. At the same time, the parameters that influence the calculation during a performative assessment are no longer a purely engineering problem, since 3D modeling is of primary importance in defining the numerical output. The role of the designer along with the selection of the tools becomes all more relevant in this direction. A framework is presented hereby, which can be used for the selection between different BIM tools for daylight assessment. An insight is also given on the major parameters that can affect the outcome and on the obstacles that were experienced in four case-studies in relation to data exchange and information flow.

title	Tree-Structure Canopy:A Case Study in Design and Fabrication of Complex Steel Structures using Digital Tools
source	International Journal of Architectural Computing vol. 11 - no. 1, 87-104
summary	This paper describes and reflects on the design and manufacturing process of the Tree-Structure canopy for the WestendGate Tower in Frankfurt upon Main, completed early 2011.The project investigated fabrication and assembly principles of complex steel structures as well as the integration of contemporary computational design, engineering, optimization and simulation techniques in a collaborative design approach. This paper focuses on the notion of modular standardization as opposed to non standard customized components. It also engages with issues relating to digital production tools and their impact on construction cost, material performance and tolerances. In addition it examines the reconfiguration of liability during a planning and construction process, an aspect which can be strongly determined by fabrication companies rather than the architect or designer.This paper is written as a reflection on the complete building process when contemporary digital tools are used from design through to fabrication. It studies both the generation of the steel structure as well the ETFE cushion skin. It reports on a collaborative project, where the main author was responsible for the canopies design, parameterization, digitalization and fabrication, as well as for the dissemination of the outcomes and findings during the design and realization process.As such it represents an example of research through design in a contemporary and evolving field.The canopy received a design award by the Hellenic Architecture Association.

summary	Visual rules are powerful in loosely capturing the impact of material behavior on form in designer’s hands-on experimentation. They present a first step to translate the causal relations between material and form to computation without sacrificing the uncertainties in the designer’s interaction with the materials. This study investigates how to model the relation between material and form with visual rules so that the model embodies some of the phenomenological aspects of reality, rather than merely reproducing it.

summary	This ongoing investigation aims to learn from nature novel material organizations and structural systems in order to develop innovative architectural system. We developed a multidisciplinary approach, using scientific analysis and design research and prototyping. We focus on the study of a “living fossil” fish, whose armor system is so efficient it has remained almost unchanged for millions of years. We investigate its morphological characteristics, its structural properties, the assembly mechanisms and the underlying material properties in order to derive new principles to design new enhanced structural systems. We use micro computerized tomography and scanning electron microscopy to observe microstructures, parametric design to reconstruct the data into digital models and then several 3D printing technologies to prototype systems with high flexibility and adaptive capabilities, proposing new gradual material interfaces and transitions to embed performative capabilities and multifunctional potentials.

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

summary	In relation to cities, wind is one of the less studied meteorological parameter. Constant vertical rate variations from meso scale to micro scale, altogether with strenght, direction, velocity of the urban canyon, makes the wind a complex subject of study. To achieve this, a methodological strategy that addresses the wind's multi dimensionality was raised. It was aplied to Punta Arenas, the southernmost city in the world, where most of the time winds come 90% from the same direction with speeds reaching 128 km/h. Wind's constant directional behavior allows the recognition of areodynamic phenomena produced, in the first instance, for the wind profiles influenced by the urban rugosity and then, at morphologycal level, the aerodynamic behavior of the layered fluids over the building bodies, generating a regular pattern between solids and fluids. The strong winds in cities with cold climate influence the use of public spaces, which, not being designed under this conditions, do not develop proper levels of thermal comfort.

summary	I have conducted a study to explore aerodynamic performance as a driver for skyscraper design, utilizing up-to-date parametric design and computational fluid dynamics (CFD) technologies readily available to architects. Previous scientific research has suggested strategies in modifying the form of skyscrapers for the purpose of improving their aerodynamic performance. I have incorporated six of such strategies into parametric design tool to produce a matrix of 60 prototypes. These prototypes are subjected to qualitative and quantitatively evaluation iterations to yield the most optimized design, with considerations given primarily to aerodynamic performance, and secondarily to structural robustness, program potential, and image attractiveness. The selected design option is further developed into a skyscraper concept. A multi-staged aerodynamic performance-driven design process is the most important result of the study. In addition, two valuable insights have been obtained: first, to inject a new inspiration into the design of skyscrapers, I have implemented the MultiDisciplinary Optimization (MDO) methodology from the aerospace industry. Second, I am able to support form-generation parametric design by quantitative evaluation process.

summary	This paper presents the impacts of different street orientations and street zones of a typical Dutch residential area on micro-scale human thermal comfort. The spatial and temporal variation of mean radiant temperature (T mrt ) of a typical summer day in Rotterdam, The Netherlands, is simulated by using an established long- and short-wave 3D radiation fluxes model (SOLWEIG). This model calculates human radiation load and expresses this as a T mrt . Hereby we simulate and analyse the T mrt variations for three zones of a street consisting of a centre area for cars and the adjacent pedestrian zones for pedestrians and bicycles. The streets are azimuth rotated. The simulation and analysis results show various T mrt patterns of the three zones in the different orientations at different periods during daytime. We show that the spatial distribution of T mrt at street level strongly depends on street orientation and street zone. This is crucial since optimizing street configuration will directly influence the human thermal comfort in relation to street orientation and street zone. Finally we present a time adjusted framework of thermal comfort and classify the various T mrt for each zone and orientation.

summary	Outdoor thermal comfort for pedestrians becomes important issues in urban planning affecting everyone’s daily lives. Mean Radiant Temperature (T mrt ) is one of the most important parameters in micro climate. In this study, we built a computerised model with variable and typical building types. Then a radiation model SOLWEIG was used to simulate pavements’ T mrt spatial variations. We analysed and discussed the simulation results by comparing different building types. We used RayMan to find some relationship between thermal comfort index PET or PMV. Our finding can act as a reference for architects and planners to make design decisions on quantifying the thermal comfort in specific urban environment and their building types.

summary	A so-called “Design Process Investigation toolbox” (DPI toolbox), has been developed. It is a set of computational tools that simulate spatial-structural design processes. Its objectives are to study spatial-structural design processes and to support the involved actors. Two case-studies are presented which demonstrate how to: (1) study the influence of transformation methods on design instances and (2) study the influence of transformation methods on the behavior of other transformation methods. It was found that in design instances with the same type of structural elements the influence of a specifically varied transformation method is more explicit; while, when different types are present this influence is more undetermined. It was also found that the use of two specifically different structural modification methods have little influence on the sub-sequential spatial transformation method.

summary	Biomimicry, where nature is emulated as a basis for design, is a growing area of research in the fields of architecture and engineering. The widespread and practical application of biomimicry as a design approach remains however largely unrealized. A growing body of international research identifies various obstacles to the employment of biomimicry as an architectural design method. One barrier of particular note is the lack of a clear definition and methodology of the various approaches to biomimicry that designers can initially employ. This paper attempts to link biological principles with computational design in order to present a design methodology that aids interested architects within the preliminary design phase.

summary	Architecture, nowadays, is an even more demanding activity in which complexity is the keyword: complex forms, complex functions and complex structures require sophisticated facilities and components, for example, ‘The Cloud’ of D. and M. Fuksas in Rome. These complexities can give rise to numerous risks, among which fire is frequently a central problem. The fire safety norms do not involve an approach integrated with other instruments or building model (BIM), but provide a list of information and constraints. These codes are now shifting away from a prescriptive-based towards a performance-based method due to recent progress in fire safety engineering. Following this approach, a case study simulation of a multi-purpose centre was carried out in Tivoli, near Rome. This simulation allowed greater freedom in architectural composition, a lower risk to people, a larger number of material and building components used and higher safety standards to be achieved. The model is based on the FDS (Fire Dynamics Simulator) language, a simulation code for low-speed flows, focused on smoke, particle and heat transport by fire.

title	Does the Debate on Stress Effect Lead Evacuation Simulation Models to Different Performances?

summary	There exists a long time debate over the rational state of the evacuees in the evacuation simulation. Sime et al. insisted that the evacuees behave rationally in most cases. Following this argument Arthur and Passini concluded that if a setting works well under normal conditions, it will have a better chance of working well in emergency conditions. Such an argument for rational decision-making makes statistical models, such as Utility Maximizing Model (UMM), acting as proper framework for choice modelling in evacuation. However, on the other side, some people pointed out that there exists panic in the evacuation and bounded rationality theory, represented by pruned Decision Tree Model (DTM), should be adapted in choice modelling instead. Such a debate over stress effect causes hesitations and uncertainties when researchers try to select a proper model framework for their practical simulation. This study compared the performances (prediction accuracies) of the UMM and DTM with the same set of choice data collected in a virtual evacuation experiment. With a similar level of performance on both sides, it is suggested that the on-going debate does NOT bring any difference to the choice modelling in practical evacuation simulation. It is time to improve the performance rather than to continue the debate.

summary	The propose paper presents an ongoing research which main goal is to use cork in a customized modular façade system. Cork is used due to its ecological value, renewable characteristic, insulation properties and aesthetic value. The modular system design is bio-inspired in the microscopic cork pattern and the study aims at reproducing in the façade some of the natural characteristics that enable cork to be suitable for the function it plays in construction. Façades are design by a generative design process based on a parametric shape grammar which encodes shape rules and an algorithm to guide the generation. The developed cork modules are part of a back-ventilated façade system which is assembled upon a substructure that reproduces the cork cell structure and enables both the assemblage of the modules to the support wall and the connection between them.
