    Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Architecture, 2008.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.MIT Institute Archives copy: with CD-ROM; divisional library copy with no CD-ROM.Includes bibliographical references (leaves 70-72).There are building systems, called "modularized", in which the component systems (for structure, lighting, etc) can be analyzed and synthesized independently since their performance and design do not interact or affect one another. There are other building systems, called "coupled", in which the component systems do interact and influence one another. The thesis acknowledges that in a building there are both sub-systems that act independently and others that interact. While many design processes have been proposed for dealing with discrete sub-systems, there is no systematic study for building sub-systems that interrelate. This thesis examines a different design approach called integrated. The term "integrated" has a dual utilization in this study. The first use refers to the integration of form and building performance. The second use refers to the integration of interrelated and diverse building performances involving multiple disciplines. The integrated design approach analyzes and evaluates several interrelated design systems involving different disciplines in the early design phase. The goal of the approach is the generation of design alternatives guided simultaneously by two basic objectives: the aspiration for form exploration and the satisfaction of the performances of interrelated systems. After defining a framework for an integrated design approach, which includes inter-disciplinary collaboration, unified design, optimization, simulation, and other formal and digital techniques, the approach will be demonstrated in a case study. The objective of the case study is to demonstrate that the integrated design approach has validity and can be realized, in this case, for the generation of high-rise buildings guided by structural, lighting, zoning codes, and aesthetic criteria.by Eleftheria Fasoulaki.S.M

    Performative design strategies: The synthesis process of a woven complexity

    This chapter focuses on the synthesis of performative building design. Performative design requires the use of analysis tools and building information modelling to predict performance and guide activities and decisions. However, there are different views of design: design as a sequence of design experiments, design as the finding of solutions to design problems, and design as purely rational decision making. Existing tools and software are only partly aligned with these views, posing challenges for those wishing to employ them. This chapter reviews the fit between these views of the design process and computational support for performative design. It is concluded that the traditional roles of architects and engineers may need revision. Furthermore, there is a need to develop a new design curriculum that caters for performative design

    La Biomimicry è una scienza applicata che studia le forme, i materiali, i sistemi e i processi naturali per individuare soluzioni applicabili anche a problemi umani. Tale scienza trova applicazione in molti campi, quali l’agricoltura, la medicina, l’ingegneria e l’architettura. Grazie ai progressi compiuti nella modellazione parametrica, ad oggi sono disponibili potenti strumenti che, oltre alla simulazione energetica, consentono di esplorare le potenzialità delle soluzioni tratte dal mondo naturale nella progettazione architettonica, superando i limiti della semplice imitazione della forma. Una delle maggiori sfide per gli architetti negli ultimi anni è la riduzione della domanda energetica del costruito. Per i climi caldi, le esigenze di ventilazione e raffrescamento sono pertanto fattori cruciali per migliorarne la prestazione energetica. La tesi di ricerca affronta il problema della progettazione e dell’efficienza energetica dell’involucro edilizio in contesti climatici caldi, quale l’Egitto. A tal fine, è stato definito e applicato un approccio progettuale biomimetico-computazionale, per studiare e analizzare i comportamenti adattivi di termoregolazione di vari organismi naturali. In particolare, il lavoro di ricerca esplora possibili soluzioni architettoniche, ispirate a caratteristiche biologiche, per l’involucro di un edificio per uffici, con l’obiettivo di ridurre la domanda energetica per il raffrescamento. L’involucro dell’edificio è stato modellato parametricamente utilizzando Grasshopper Visual Programming Language per Rhino 3D Modeller, applicando inoltre alcuni algoritmi evolutivi multi-obiettivo per ottimizzare la soluzione architettonica rispetto al duplice obiettivo di diminuire i carichi di raffrescamento e mantenere un buon livello di illuminazione naturale. In tal modo, la riduzione dei carichi di raffreddamento non comporta un incremento dei consumi elettrici per l'illuminazione artificiale. Le prestazioni termiche dell’edificio sono state valutate con il software EnergyPlus. La soluzione architettonica esplorata è una facciata a doppia pelle ispirata a vari principi della natura. Le prestazioni della soluzione proposta sono state confrontate con quelle di un edificio per uffici esistente a Il Cairo. Il modello dell’edificio è stato ricostruito sulla base di planimetrie e specifiche sui materiali presenti; inoltre la disponibilità di dati sui consumi energetici per il raffrescamento dell’edificio ha permesso di valutare l’accuratezza della prestazione energetica calcolata con il software di modellazione. La soluzione progettuale è stata comparate anche rispetto alle prestazioni di una tipica facciata a doppia pelle. Inoltre le prestazioni termiche calcolate con EnergyPlus sono state confrontate con quelle ottenute con software di simulazione fluidodinamica computazionale (CFD), più accurati nel calcolo delle facciate a doppia pelle. Tale comparazione ha permesso di identificare il grado di errore e l’appropriatezza dell’uso di EnergyPlus nelle fasi iniziali della progettazione. La facciata a doppia pelle proposta consente una diminuzione della domanda di raffrescamento fino al 13,4%, migliorando al tempo stesso il livello di illuminazione naturale, che spesso costituisce uno dei maggiori limiti per l’applicazione di tale sistema. La ricerca termina con una sintesi dei risultati ottenuti e una valutazione complessiva del processo di progettazione presentato, degli strumenti di progettazione/simulazione utilizzati e delle prestazioni dell’involucro proposto, discutendone vantaggi e limiti. Sulla base delle sperimentazioni e dei risultati conseguiti, sono state individuate linee guida e raccomandazioni per la progettazione delle facciate a doppia pelle nei climi caldi. Inoltre viene fornita una matrice che raccoglie tutte le idee biomimetiche esplorate e analizzate, che rappresenta una mini-banca dati per architetti o designer interessati a questo approccio progettuale nell’affrontare i problemi di termoregolazione del costruito. Infine, la differenza di accuratezza tra i risultati di EnergyPlus e quelli dello strumento CFD è risultata trascurabile.Biomimicry is an applied science that derives inspiration for solutions to human problems through the study of natural designs, materials, structures and processes. Many fields of study benefit from biomimetic inspirations, such as agriculture, medicine, engineering, and architecture. Technological advances in parametric and computational design software in addition to environmental simulation means offer very useful tools in order to explore the potential of nature’s inspirations in architectural designs that does not just mimic shapes and forms. Energy efficiency is one of the major and growing concerns facing architects. Cooling and ventilation needs are critical factors that affect energy efficiency especially in hot climates. This thesis addresses the problem of designing building skins that are energy efficient in the context of hot climates such as that in Egypt. The research attempts to define and apply a biomimetic-computational design approach to study and analyse natural organisms in terms of their behaviour regarding thermoregulation. Aiming to decrease cooling loads, the research explores possible architectural solutions for a biologically inspired skin system for office buildings. The building’s skin is parametrically designed using Grasshopper Visual Programming Language for Rhino 3D Modeller, and it is optimised using multi-objective evolutionary algorithms which are particularly important in the attempt of finding a range of solutions that reduce cooling loads while maintaining daylight needs. Consequently, the reduction in cooling loads should not be at the expense of increased energy consumption in artificial lighting. Simulations regarding the thermal performance were performed using EnergyPlus. A Double-Skin Façade (DSF) is proposed based on inspirations from nature. In order to evaluate the performance of the proposal, it is compared to the performance of the skin of an existing office building in Cairo acting as a reference case. Data regarding the reference case such as the building drawings, material specifications and annual cooling consumption were obtained in order to build its digital model and assess its accuracy. The proposed design is also evaluated by comparing it to a typical flat DSF. The obtained results regarding the thermal performance of the proposed building skin are verified by comparing them to results of more accurate simulations performed using Computational Fluid Dynamics (CFD). The aim is to know the degree of error as well as the appropriateness of using EnergyPlus for geometrically-complex DSFs in early design phases when CFD is not practical. The proposed DSF was able to decrease cooling loads by up to 13.4% while improving daylight performance at the same time which is often one of the main challenges of using DSFs. The research criticises the presented design approach as a whole, the design/simulation tools used and the performance of the proposed skin discussing their benefits and limitations. Based on the design experimentation and results, general guidelines and recommendations for DSF design in hot climates are presented. Additionally, the research presents a compiled matrix of the biomimetic ideas explored and analysed in order to serve as a mini-data bank for architects or designers interested in this design approach in addressing thermoregulation problems. Finally, the comparison between EnergyPlus and CFD software results showed minor differences

    The research investigates strategies of dynamic surface formations in a transfer from sartorial fashion to architecture. ‘Remote Control Dress’ (Hussein Chalayan), ‘Dress becomes Body (Rei Kawakubo) and ‘A-Poc’ (Issey Miyake) are precedents of specific technologies and techniques that produce responsive, performative, or phenomenal dresses. These garments can deliver generative surface methods for an architecture operated through the user. The research frames key parameters (cutting scheme, constructive line, programmatic insertions, and operative field) and their respective characteristics and interrelations in analysis. Thus, principles are derived and channeled into performative design models in a media rotation with a conversion between digital and analogue modeling. The paper discusses the potential of these dynamic design models in a design process that addresses the change capacities of architecture in a shifting cultural and programmatic context

    What Will the Architect Be Doing Next? How is the profession of the architect evolving as the focus of society shifts from sustainability to resilience or reactivist-driven design demands?

    A more engaging and visionary role for architects is emerging, altering focus from a technological advisor to a more sociological engineer or entrepreneur. By researching a selection of current architectural practices an attempt is made to describe this evolution of the architect’s role and to assess if this is truly a new development or even a paradigm shift. Based upon on an analysis of texts by scholars and written conversations with architects on the subject of sustainable architecture, resilient architecture, agency in architecture and reactivist architecture, supplemented with additional statements by architects on the matter of architectural practice, an evolution of this role made clear and put into perspective. The aim of this review therefore is to distil some kind consensus within architectural practice of how the architect’s role is to evolve in the foreseeable future. It appears that reactivist architecture as a descriptive set of principles has absorbed elements of all of the above, becoming more than the sums of its parts and allowing for a new role for the architect to emerge

    Performance driven generative design systems: Agent based model driven design methodologies in architectural education

    Full text link
    The research paper elaborates upon multi-performative generative design strategies by means of associative computational simulations incorporating social, environmental, spatial and structural dimensions. The interdisciplinary research driven design approach presented in this paper is exemplified via design experiments conducted at Hyperbody, TU Delft’s graduation studios. These experiments consciously fuse Agent based modeling (ABM), Associative and parametric design techniques, Swarm intelligence Models and Environmental analysis to evolve a comprehensive, performance driven design methodology. A looped process of iterative information exchange between analytical, aesthetic, fabrication and real-time interactive behavior based modes of experimentation for evolving performance driven architectural formations is thus proposed. This inter-performing data-driven approach devoid of its reliance on architecture styles and typologies is thus deemed a democratic methodology to understand our built environment and to bottom-up produce sustainable architectural morphologies. An interdisciplinary mode of operation to invent a new take on pre-processing via integration rather than post-design optimization of architectural space for the sake of sustainability is thus seen as a vital outcome of the research and design methodology
