summary	The research presents an architectural method and model that organise material composites into weather-powered response building envelopes. The work is done through a set of simulation strategies including simulation of thermal sensation, simulation of material behaviours of a developed dynamic architectural envelope based on bi-material deflection and simulation of a design process based on evolutionary computation. The work finds that the proposed method and model can create dynamic expressive and environment-oriented functional building envelopes. The approach allow time-based articulation and making of architectures that respond to the thermal environment, thereby creating a basis for developing buildings that are intimately linked to dynamic environmental and human occupancy patterns.

summary	This paper deals with the research of the building shape in a constant and dialectical relationship with thermal performance. The purpose of this research is to understand and explore the dialogue between shape and performance with generative strategies. The method was based on the works by Oxman (2010), Olgyay (2015), and Di Mari & Yoo (2012), by means that relate the form to performance issues. The thermal performance data found to result from the relationship between thermal conditions, the shape of the envelope, and the characteristics of the eight Brazilian bioclimatic zones.

title	Designing a Building envelope using parametric and algorithmic processes
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 797-801.
summary	This article presents a case study on a vertical building envelope design considering Recife ?s climatic conditions. It consists of the utilization of parametric and algorithmic processes to distribute sun shading devices. The study uses computational tools such as Grasshopper and the DIVA for Grasshopper. The latter is a thermal energy simulation tool that uses the Energy Plus 7.0 and Daysim for calculations. The model uses incident solar radiation simulation on the envelope as basis for distribution of shading devices. The result is a parametric model that automatically responds to urban and climatic characteristics, through simulations integrated to the 3D model.

doi	https://doi.org/10.52842/conf.caadria.2015.345
summary	This study focuses on developing three-dimensional solar panels, as an alternative to traditional flat Photovoltaic (PV) surfaces in Building Integrated Photovoltaic (BIPV). We propose to increase the energy efficiency of buildings by using the entire envelope for energy production as well as by increasing the efficiency of solar energy output in orientations which were traditionally considered as non-ideal. The panels are constructed from Polycarbonate with integrated flexible photovoltaic film, solar paint or dye. The methodology included digital algorithm-based tools for achieving optimized variable three-dimensional surfaces according to local orientation and location, computational climatic simulations and comparative field tests. In addition, the structural, mechanical and thermal properties of the integration between flexible PV sheets and hard plastic curved panels were studied. Interim results demonstrate a potential improvement of 50-80% in energy production per building unit resulting from geometric variations per-se. The dependence of energy production by surface geometry was revealed and an optimized method for solar material distribution on the surface was proposed. A parametric digital tool for automatic generation of optimized three-dimensional panels was developed together with a database and material models of the optimized panels system.

summary	This work is part of a research on decision-making processes in architecture involving computer programs in the early stages of designing the building envelope. The research involves two steps: (1) intuitive processes analysis during the handling of the building envelope components - floor, roof, walls, windows, solar protection elements - and (2) generative processes analysis of building envelopes supported by performance models. This article is the first step, analyzing four housing prototypes, designed and built for the Solar Decathlon competition. First, the building envelope elements and thermal characteristics of these prototypes were modeled; then different materials that make up the envelope were tested, aimed at assessing thermal performance against the modifications proposed in six different scenarios. The results showed that it is possible to obtain intuitive solutions that equalize temperature changes in the early stages of design with computing environments even without the use of detailed data on the characteristics of buildings, features of the later stages of the project.

title	Computational and Physical Modeling for Multi-Cellular Pneumatic Envelope Assemblies
source	International Journal of Architectural Computing vol. 13 - no. 2, 143-169
summary	This article describes recent research on the performative, formal and aesthetic potentials of multicellular pneumatic foil-based envelope systems for lightweight, responsive building skins able to control thermal insulation and air exchange with minimal amounts of energy and mechanical components. The prototype-based research involves the use of principles from biological examples of pneus, which inform the design of physical analogue models at an architectural scale. The process entails physical-computational feedback loops wherein physical performance findings are fed into computational design models for pneumatics and membranes, as well as modified energy models, in order to advance the predictive design capacities of simulation tools in designing such systems. In this process, material agency allies with computational agency to develop novel possibilities for dynamic pneumatic envelopes.

summary	The Klimasymmetry research project is part of ongoing investigations that ask how the design of a surface emanating radiant heating and cooling can influence the non-visual spatial boundaries created by asymmetrical thermal conditions. This research investigates the nature of the surface as an initiator of a thermal environment in an attempt to locate thermal tactility and the spatial perception according to radiant heat transfer. Surface qualities such as the quantity of area and thermal capacity of the material affects the ability of the panel to emit or absorb electromagnetic radiation, informing the geometry, topography, and location of each panel relative to the human body.

doi	https://doi.org/10.52842/conf.acadia.2015.357
summary	This paper presents a workflow called the ‘heuristic optimization workflow’ that integrates Octopus, a Multi-Objective Optimization (MOO) engine with Grasshopper3D, a parametric modeling tool, and multiple simulation software. It describes a process that enables the designer to integrate disparate domains via Octopus and complete a feedback loop with the developed interactive, real-time visualization tools. A retrospective design of the Bow Tower in Calgary is used as a test case to study the impact of the developed workflow and tools, as well as the impact of MOO on the performance of the solutions. The overall workflow makes MOO based results more accessible to designers and encourages a more interactive ‘heuristic’ exploration of various geometric and topological trajectories. The workflow also reduces design decision uncertainty and design cycle latency through the incorporation of a feedback loop between geometric models and their associated quantitative data. It is through the juxtaposition of extreme performing solutions that serendipity is created and the potential for better multiple performing solutions is increased.es responsive systems, which focus on the implementation of multi-objective adaptive design prototypes from sensored environments. The intention of the work is to investigate multi-objective criteria both as a material system and as a processing system by creating prototypes with structural integrity, where the thermal energy flow through the prototype, to be understood as a membrane, can be controlled and the visual transparency altered. The work shows performance based feedback systems and physical prototype models driven by information streaming, screening, and application.

title	The definition of semantic of spaces in virtual built environments oriented to BIM implementation
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 331-346.
summary	The BIM today can be a provider of inputs to performance analysis of different phenomena such as thermal comfort, energy consumption or winds. All these assessments are fundamental to the post occupation of the building. The attainment of approximate information of how the future building would behave under these conditions will reduce the waste of materials and energy resources. The same idea is used for evaluating the users occupation. Through simulation of human behavior is possible to evaluate which design elements can be improved. In complex structures such as hospital buildings or airports is quite complex for architects to determine optimal design solutions based on the tools available nowadays. These due to the fact users are not contemplated in the model. Part of the data used for the simulation can be derived from the BIM model. The three-dimensional model provides parametric information, however are not semantically enriched. They provide parameters to elements but not the connection between them, not the relationship. It means that during a simulation Virtual Users can recognize the elements represented in BIM models, but not what they mean, due to the lack of semantics. At the same time the built environment may assume different functions depending on the physical configuration or activities that are performed on it. The status of the space may reveal differences and these changes occur constantly and are dynamic. In an initial state, a room can be noisy and a moment later, quiet. This can determine what type of activities the space can support according to each change in status. In this study we demonstrate how the spaces can express different semantic information according to the activity performed on it. The aim of this paper is to simulate the activities carried out in the building and how they can generate different semantics to spaces according to the use given to it. Then we analyze the conditions to the implementation of this knowledge in the BIM model.

title	Mass Regimes: Geometric Actuation of Thermal Behavior
source	International Journal of Architectural Computing vol. 13 - no. 2, 169-194
summary	The Mass Regimes is a research project that investigates the effect of complex geometry on processes of passive heat distribution in thermal mass systems. In the context of systems thinking, this research intends to instrumentalize design principles that engage a wider range of design tactics for choreographing thermal gradients between buildings and their environment. Research for this project has brought about a deeper understanding of how specific geometric manipulations of surface area over the same mass (Figure 1) affect the rate of thermal transfer. Leveraging physical simulations of geometric populations, along with current computational and design tools, the project sheds light on performative trends that may enhance creative design explorations in the use of passive systems. Preliminary analysis of varied geometric populations suggest an exciting trend and the possibility for a more synthetic incorporation of morphology, one in which surface geometry can be passively utilized to generate effects with more fidelity over the pace of thermal absorption and the release of sensible heat.

title	Modulating Thermal Mass Behavior Through Surface Figuration

doi	https://doi.org/10.52842/conf.acadia.2017.202
summary	This research builds upon a previous body of work focused on the relationship between surface geometry and heat transfer coefficients in thermal mass passive systems. It argues for the design of passive systems with higher fidelity to multivariable space between performance and perception. Rooted in the combination of form and matter, the intention is to instrumentalize design principles for the choreography of thermal gradients between buildings and their environment from experiential, spatial and topological perspectives (Figure 1). Our work is built upon the premise that complex geometries can be used to improve both the aesthetic and thermodynamic performance of passive building systems (Cupkova and Azel 2015) by actuating thermal performance through geometric parameters primarily due to convection. Currently, the engineering-oriented approach to the design of thermal mass relies on averaged thermal calculations (Holman 2002), which do not adequately describe the nuanced differences that can be produced by complex three-dimensional geometries of passive thermal mass systems. Using a combination of computational fluid dynamic simulations with physically measured data, we investigate the relationship of heat transfer coefficients related to parameters of surface geometry. Our measured results suggest that we can deliberately and significantly delay heat absorption re-radiation purely by changing the geometric surface pattern over the same thermal mass. The goal of this work is to offer designers a more robust rule set for understanding approximate thermal lag behaviors of complex geometric systems, with a focus on the design of geometric properties rather than complex thermal calculations.

summary	To improve indoor thermal environment, it is necessary to promote a lean design process, so forecasting and consensus building by experiment and numerical calculation from the design stage have become essential. Rapid advances in software and hardware allow feedback to be generated on novel design alternatives, rather than relying on simulation results based on past designs. However, this concept has not been fully verified. Therefore, this study presents an integrated design tool which consists of Computational Fluid Dynamics (CFD), Virtual Reality (VR), Augmented Reality (AR) and Building Information Modeling (BIM). The tool was applied to the problems of an actual housing design project. Both the content of design feedback on design problems revealed through simulations in the project, and the features in the feedback process were discussed.

summary	Environmental analysis as part of the initial design process, affords precise consideration of the bioclimatic human conditions within the environmental local context. The daily growth in inter alia knowledge of effective parameters in environmental conditions, quality weather data, human thermo-physiology studies – all contribute to improving the potential for achieving a relatively accurate analyses of environmental conditions by overlaying and computing all the climatic and thermo-physiological data. This paper describes a digital method for examining different points in the same context by computing all the input data available to understand the corresponding human comfort condition levels, thus leading to better decision-making at early design stages. Information about the site, climate, human thermo-physiology and behavioral aspects among others are collected where each data parameter is matched and analyzed to the context of every node on the model through a series of specific computational algorithms. Thereafter, the data from the nodes are statistically cleaned, classified and integrated based on the CBE thermal comfort calculation for ASHRAE-55. The results obtained using this method, can be tailored according to the desired outcomes. The proposed method identifies effective factors for human comfort condition improvement for different points on the context. It also provides a means to priorities specific parameters so that they can be manipulated for optimal digital design solutions, ie. Aligned to the desired conditions in the specific parts of the site with the aim of optimize outdoor space usage.

summary	Recent developments in responsive electroactive materials are increasing the rate at which next-generation façade technologies can respond to environmental conditions, building energy demands, and the actions of building occupants. Simulating the real-time performance of dynamic façade systems is critical for understanding the impacts that occupant response will have on whole-building energy performance and architectural design. This paper describes a method for real-time analysis of the multi-zone building performance impacts of occupant interaction with a dynamic façade system, the Electroactive Dynamic Display System (EDDS). The objective is to optimize EDDS implementation and define system limitations, incorporate EDDS as a dynamic factor in multi-zone building energy analyses, and provide real-time feedback of building performance data based on environmental conditions and occupant interactions. Preliminary results of parametric simulation methods demonstrate the ability of dynamic façade systems to consider real-time occupant interaction in the analysis of daylighting and thermal performance of buildings.

summary	The thermal categories established by Reyner Banham are useful for identifying historical points at which structure is "liberated" from the task of being the prime controller of the environment, as well as identifying the impact on design culture, which given the freedom to invest structure with a high degree of sculptural plasticity, exaggerated the disconnect between form and thermal performance, resulting in a situation in which form is inherently viewed as incapable of performing work equivalent to mechanical systems.

summary	The Minha Casa Minha Vida institutional housing program aims to build millions of residences in Brazilian cities. This situation decreases the building quality as the Federal Government, who founds the program, demands very low costs, so it is even more complicate to achieve quality enhancement. To solve this situation, many regulations have been instituted and, in 2013, ABNT published NBR 15575, a regulation regarding housing building performance, including aspects such as thermal, acoustic and maintenance performance. This paper aims to study thermal analysis section and the possibility to use BIM to achieve accurate data about thermal performance.

summary	Thermal Form, is architecture that does work. Or, it is the application of energy as information to architectural geometry, with the express purpose of using the resistance of structure against an opposing thermodynamic force, in order to manipulate and direct flows that exist in both the interior and along the exterior of a building. By examining the relationship between surface configuration, surface area and type of energy transfer occurring - with a focus on the mechanism of transfer - thermal form strategies can be used to further optimize existing building typologies and environmental control system strategies, or, perform a more radical detouring of the atmosphere of a building.

summary	The idea of an emergent or generative form based on repeating rules of development borrowed from the field of developmental biology has provided fertile ground for inspiration for architectural theory and computational design. With simple constraints developed iteratively, complex geometry and form generation can be distilled down to a list of developmental rules or functions in order to deterministically generate form. The ideas and illustrations of naturalists on organic form and developmental biology leading back to the turn of the 20th c., such as the work of D'arcy Wentworth Thompson and Ernst Haeckel, have inspired architects from Louis Sullivan all the way to contemporary generative design. This study revisits this design tradition of biomimetic geometries based on deterministic rules for the iterative development of forms based on biological analogs and models for growth. A series of semi-regular compound patterns were developed using parametric modeling and iterative rules. These geometries were then applied to surface topologies as a decorative tactile embellishment resulting in complex thermodynamic conditions. A series of physical prototypes where then developed with different high-relief patterns and pattern densities. Positive prototype geometries were then produced using stereolithography for casting plaster molds for the production molding of finished ceramic pieces for thermal analysis using digital thermography. By studying the performance of these complex geometries as physical prototypes under controlled experimentation, high-relief surfaces and the resulting thermodynamic conditions can be understood not just qualitative experience, but also quantitatively through measured performance metrics and innovative tools for analytical analysis.

summary	This paper describes the development of the StretchPLAY prototype as a part of the Social Sensory Surfaces research project, focusing on the design of tactile and responsive environments for children with Autism Spectrum Disorder (ASD). The project is directed specifically at issues with sensory processing, the inability of the nervous system to filter sensory input in order to indicate an appropriate response. This can be referred to as a “traffic jam” of sensory data where the intensity of such unfiltered information leads to an over-intensified sensory experience, and ultimately a dis-regulated state. To create a sensory regulating environments, a tactile structure is developed integrating physical, visual and auditory feedback. The structure is defined as a textile hybrid system integrating a seamless knitted textile to form a continuous topologically complex surface. Advancements in the fabrication of the boundary structure, of glass-fiber reinforced rods, enable the form to be more robustly structured than previous examples of textile hybrid or tent-like structures. The tensioned textile is activated as a tangible interface where sensing of touch and pressure on the surface triggers ranges of visual and auditory response. A specific child, a five-year old girl with ASD, is studied in order to tailor the technologies as a response to her sensory challenges. This project is a collaboration with students, researchers and faculty in the fields of architecture, computer science, information (human-computer interaction), music and civil engineering, along with practitioners in the field of ASD-based therapies.
