title	Exploring Urban Space: Volumetric Site Analysis for Conceptual Design in the Urban Context
source	International Journal of Architectural Computing vol. 11 - no. 2, 157-182
summary	This paper proposes a set of new analytic and visualization methods for conceptual design in the urban context. The methodology is based on the discretization of the urban site into a volumetric grid of points. For each of these points, different physical properties such as solar radiation, airflow, and visibility are computed. Subsequently interactive visualization techniques allow the observation of the site at a volumetric, directional and dynamic level, making visible information that is typically invisible. Several case-studies demonstrate how this allows to generate suggestions, for example, for the definition of the form of a building or for the rationalization of its surfaces. This approach aims at developing a conceptual design process that allows the fusion of active technologies, passive methods, and expressive aspects, in cohesive concepts able to embrace and exploit the diversities of an urban site.

title	Towards Computer Aided Life-Cycle Costing
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	Sustainability is recognised as a necessary public good. Building sustainable buildings requires architectural methods, specifically CAD systems, that include suitable predictions of long term performance. Unfortunately the predominant view in the Building Industries of the Developed world is essentially short term; this is because building developers – not being the end users - are essentially interested in short term profit. Until they can see the ‘value-added’ by sustainability impacting on the selling price of their buildings, they will not be motivated to build ‘sustainably’. This paper describes the issues that have led to this situation. It discussed how the advent of computers has allowed life-cycle data to be gathered over time, and may be included intro CAD system databases to enable sustainability performance predictions to be made. Once made we are now able to reap the benefits by performance benchmarking. The availability of this building performance information on-line is making life-cycle costing more readily available, and more accurate, allowing building developers, owners and users to make rapid and timely feasibility studies well in advance of design. This also allows owners to test various capital to operating cost options in order to get the best economic performance over time, as well as map future capital replacement cycles. These emerging possibilities are discussed in this paper.

summary	This article presents a didactic experience carried out with the use of a BIM tool in the Thermal Environmental Comfort discipline of the graduate course in Architecture and Urbanism of a private Higher Education Institution in the city of Salvador-Bahia. Starting in 2020, students began designing solar protection devices using a geometric model in Revit. The method described in Annex I of the Technical Regulation on the Quality of Energy Efficiency Level in Residential Buildings (RTQ-R) was applied. The results obtained showed a better understanding by the students about the importance of correctly sizing solar protection devices for different orientations.

summary	This essay is related to the research project "The immersive experience in 360°: investigation, representation and digital immersion in the city of Rio de Janeiro in the 19th and 20th centuries", developed at PROURB in FAU-UFRJ, Rio de Janeiro/Brazil. This work will investigate the Panorama of Rio de Janeiro looking for memories and historical truths in its context: Which part represents a historical point of view? Which part is invention? How were the city and its landscape represented on the canvas? As the most well-known Rio de Janeiro's panorama, which project was idealized by the Brazilian painter Victor Meirelles de Lima (1832-1903) and the Belgian photo-painter Henri Charles Langerock (1830-1915), it was exhibited in Brussels 1888, Paris 1889, and Rio de Janeiro 1891-1896, with great recognition in all these cities. This paper will explore this Panorama, its initial studies, its landscape and the architecture depicted, newspapers descriptions of its exhibitions, and mainly, distinguishing among memories, historical truths and verisimilitudes. In order to achieve these objectives, digital and analogical systems of representations, sketches and computer graphics techniques, specially, tridimensional models will be developed and applied.

summary	Estimating a building's performance is part of the engineering and architecture discipline. Nowadays, this estimation is done using analysis tools. In many cases, these analysis tools require specialized building models that are simplifications of the actual models. Unfortunately, the adaptations that need to be done to an existing model are tiresome and make the architect less willing to evaluate variations of the building design. Moreover, in the case of buildings with complex shapes, the analyses tend to be less reliable. These problems also occur when algorithmic approaches are used to generate the building design, as the algorithmic script needs to be adapted to satisfy the requirements of the analysis tool, or the manual adaptation of the generated model needs to be repeated each time the script is executed. To solve these issues we propose Algorithmic-Based Analysis. This is a Generative Design method that, utilizing a single algorithmic-based representation of a building, can generate not only the traditional CAD or BIM model, but also specialized models for use in different kinds of analysis.

title	Affordable Computation for Architecture
source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 415-433
summary	Current architectural requirements prioritize the need to minimize the ecological footprint. By taking advantage of computational design approaches like Algorithmic Design (AD), architects can enhance their design processes with analysis, optimization, and visualization mechanisms, which are critical to explore design solutions that meet this need. However, these mechanisms are also highly time- and resource-consuming, often implying a quality tradeoff or the acquisition of High-Performance Computing (HPC) machines. The latter are not yet affordable for most design studios but, fortunately, they can be contracted as a service. This paper evaluates the impact of computation as a service in architecture and, more specifically, the remote use of HPC for AD, with the aim of reducing the time and costs associated with computationally expensive processes. A set of experiments were made involving analysis, optimization, and rendering of a selected case study. Results indicate that HPC services are advantageous, particularly when performing embarrassingly parallelizable tasks such as rendering. However, some challenges remain, namely the required expertise.

summary	This paper is about the experience to show the possibilities of the Algorithm Aided Design to a community of students and Professors that actually uses Computed Aided Design, but just for drawings, not for a full digital process. This community is hosted at Belas Artes de S?o Paulo, who in February of 2015, opened up its first Digital Fabrication Laboratory, but people there didn’t have a good idea of what it could be, beyond scale models. It shows that the new theory that supports new digital paradigms in architecture and design was the job acquired for a research group.

summary	This paper presents the development of a framework to investigate possible intersections between mass customization and flexibility in the furniture scale, based on the notion of complex modularity. The conceptual framework was implemented with parametric design as a prototypical furniture system, which allows dimensional customization and digital fabrication in reduced scale. The system was evaluated through workshops that simulated pre-configuration and reconfiguration layouts in a study room. Results showed that embedding complex modularity into furniture elements and defining measurement intervals contributed to the flexibility of the mass customized alternatives, providing the emergence of unexpected layout compositions and furniture uses.

summary	Good visualization mechanisms offer architects, and their clients, a better grasp of how their designs are going to turn out when built, and the experience one might have inside the constructions. This also helps the architect orient the design in a more informed manner. However, typically used modeling tools do not offer satisfactory visualization solutions. The operations available to view and navigate through the 3D space are flawed in terms of speed, interactivity, and real-time rendering quality. To solve this issue, we propose the coupling of a portable algorithmic design framework with a Game Engine (GE) to support interactive visualization of architectural models and increase the rendering performance of the framework. We explain in detail this integration, and we evaluate this workflow by implementing a case study and comparing the performance of the GE to architectural modeling tools.

summary	Since the great popularity of smartphones and tablets, many applications have been developed to create digital panoramas. However, its focus is turned for the seamless of the pictures and not what we can explore and understand of its different subjects. This article intends to investigate the use of a new concept of an app for digital panoramas. We assume that Panoramapp! can broaden the understanding the history of the cities by its panoramas and panoramic views, an alternative way to develop an iconographic hyper document of the central area of the city of Rio de Janeiro.

summary	This article intends to investigate the meaning of Digital Panoramas as a tool to develop an alternative reading of the urban centralities in the city of Rio de Janeiro. We assume that Digital Panorama can bring significant contributions to urban research, in three different historical layers: at the beginning of 20th century; during the 20-40’s decades, and in the current days. The strength of panoramas in urban study is particularly enhanced by interactivity. This paper aims to demonstrate new possibilities in the association of panorama’s space recognition characteristic for historical study in urban centralities.

summary	Nowadays, many buildings need to accommodate large numbers and/or large concentrations of people. Despite the efforts to produce building designs that can safely evacuate occupants, accidents continue to happen with dramatic consequences. This happens, in part, because of the difficulty in anticipating the consequences of design decisions regarding building's evacuation performance. In order to improve the situation, one needs to resort to evacuation simulation tools. These, however, have two problems: (1) they require analytic building models that are difficult to produce manually, and (2) they tend to focus on evacuations under non-emergency conditions, where panic phenomena is not present. In this paper, we propose a combination between algorithmic design and different evacuation simulators that allows for the quick simulation of many design variations.

summary	Design is characterized by change. Nowadays, addressing change in design requires enormous efforts, particularly, when the designer is exploring different solutions or when it is necessary to adapt the design to evolving constraints. This paper discusses the potential of Generative Design to help designers handling change, namely in the generation of several alternative design solutions. We propose a programming-based approach that, although requiring an initial investment, dramatically reduces the efforts of design modification. We evaluate the approach in a case study and we show that it is cost-effective in the development of an architectural design.
