Desenvolvimento de Módulo de Realidade Virtual Aplicado ao Planejamento Urbano (2018)

AUTOR | AUTHOR: Acad. Arq. Augusto Tumelero
RESUMO | ABSTRACT: A simulação e a análise de cenários urbanos apoiam o diagnóstico de sistemas urbanos, sendo uma ferramenta de análise e simulação o software Cityzoom, que oferece modelos voltados à análise do impacto de edificações sobre o ambiente urbano de forma interativa. O Modelo de Pregnância do Cityzoom fornece dados de preponderância visual de edificações em ambientes urbanos, o que é particularmente importante para projeto e licenciamento em ambientes urbanos com objetos de valor histórico e cultural. A comparação entre a observação natural de um grupo teste usando dispositivos de Realidade Virtual com dados fornecidos pelo Modelo de Pregnância do Cityzoom mostrou que o Modelo de Pregnância do Cityzoom captura de forma confiável a predominância visual de partes de edifícios ao longo de trajetos urbanos.

Regimes Construtivos em Ambiências Históricas: estudos de visibilidade em Três Coroas (2016):

AUTORES | AUTHORS: Prof. Dr. Júlio Celso Vargas, Prof. Dr. Benamy Turkienicz, Arq. Me. Julia Miranda, Arq. Me. Karen Kussler.
RESUMO | ABSTRACT: A cidade de Três Coroas apresenta duas áreas centrais consideradas de valor histórico-cultural. A valorização destes conjuntos passa pela refuncionalização dos imóveis, articulação com rotas turísticas e, principalmente, pela preservação da ambiência histórica. Em recente revisão do Plano Diretor Municipal, realizada pelo NTU | UFRGS, foram estabelecidas Áreas Especiais de Preservação do Patrimônio Histórico e Cultural nestes centros, com regimes construtivos especiais em que as novas edificações tivessem relação harmônica com as preexistências, sem obliterá-las. Um estudo de visibilidade com o auxílio do software Cityzoom permitiu a simulação de alternativas de novos envelopes construtivos que não produzissem interferência visual impactante com as preexistências. Dessa forma, ao menos do ponto de vista visual, a qualidade dos ambientes de valor histórico-cultural é garantida, ao mesmo tempo em que se viabiliza a ocupação mais intensa das áreas e a consequente dinamização econômica do município.

Supporting Tools for Early Stages of Architectural Design (2014)

AUTORES | AUTHORS: Ernesto Bueno, Prof. Dr. Benamy Turkienicz
RESUMO | ABSTRACT: In architectural design, pencil and paper remain the most frequently used media to create freehand drawings to support early design stages. Digital tools conventionally used by architects lack appropriate functionalities and do not offer friendly interfaces for the early stages of architectural design. These are the bad news. The good news are twofold: a) hardware already available can help freehand designers to digitally express their first ideas; and b) functionality principles present in experimental software combined with appropriate hardware could successfully provide a friendly and intuitive human-computer interaction in the early stages of architectural design. This paper takes special attention to the way architects interact with computers, how input devices constrain possible interactions and how functionalities can be explored through these interactions. The article summarizes basic principles to be considered in the development of an all-in-one software and create a scenario whereby these principles are simulated on a hypothetical software to be used during the early stages of architectural design.

A Conceptual Participatory Design Framework for Urban Planning: the case study workshop ‘World Cup 2014 Urban Scenarios’, Porto Alegre, Brazil (2011):

AUTORES | AUTHORS: Antje Kunze, Jan Halatsch, Carlos Venegas, Martina Maldaner Jacobi, Benamy Turkienicz, Gerhard Schmitt.
RESUMO | ABSTRACT: This paper focuses on the definition of a conceptual participatory design framework for urban planning. Traditional planning methods can no longer satisfy the growing demands on sustainable urban planning in regard to factors such as complexity, problem size, and level of detail and these limitations make the development of new approaches necessary. Expert knowledge as well as insights from stakeholders and community members need to take part equally in the decision-making process since they are responsible for a broad understanding and acceptance of final planning decisions. Therefore, a participatory framework is presented in the following, which integrates needs and requirements of stakeholders. In order to enable diverse groups of stakeholders to act conjointly, we propose the application of interactive decision support tools, which will leverage general conclusions especially to solve crucial planning decisions.

Validation and sensitivity testing of CityZoom-AERMOD model (2010):

AUTORES | AUTHORS: Pablo Grazziotin, H. Morvan, David Hargreaves, Helena Cybis, P. Ariot, Prof. Dr. Benamy Turkienicz
RESUMO | ABSTRACT: CityZoom is a computer-based tool where different design and planning attributes can be considered simultaneously, aiming to optimize the urban planning process. The current research has two objectives: (1) to enhance CityZoom and provide fast computation of air flow and pollution for urban planners; (2) to build an integrated CFD simulation into CityZoom to link urban planning and architectural engineering consultancy. This paper reviews the work done on the first objective: EPA's preferred regulatory model, AERMOD, is chosen for this task. A methodology for modelling traffic emission profiles and building geometries is developed to allow the use of AERMOD downwash algorithms in this integrated environment. Parametric tests are performed for different sets of meteorological conditions and urban scenarios. The sensitivity of the model to changes in wind speed, wind direction and the built environment is studied. To validate the model, tests are performed against data from the DAPPLE Project.

Towards a 10-Step ‘Open-framework Multi-criteria Spatial- Decision Support System’ for Pro-poor Urban Planning: exploring and systematising methodologies for Praia (Cape Verde) (2010):

AUTORES | AUTHORS: Ar. Jaime Royo Olid, Prof. Dr. Benamy Turkienicz
RESUMO | ABSTRACT: The aim of this paper is to "explore" the handling of " urban knowledge " by means of a number of methodologies which could constitute a 'Multi-criteria Spatial-Decision Support System' (MC-SDSS 2) for addressing poverty reduction in planning services delivery in cities of the 'South'. Where a SDSS is a closed all-in-one computational package, this paper refers to 'Closed-framework SDSS'. These can solve 'precise' semi-structured decision problems. Since urban planning can comprise unstructured decision-questions which cannot be resolved by means of a fully programmable procedure, the proposed architecture is that of an 'Open-framework SDSS'. In an 'Open-framework', technical experts intervene more than in a 'Closed-framework' in order to adapt the SDSS procedures in a cyclical manner to the analytical findings on a particular urban setting. This entails for the experts to iteratively identify possible intersections, integration possibilities and interrelations of different data and knowledge sources in order to formulate solvable semi-structured decision-problems.

Análise da Acessibilidade Urbana para o Planejamento da Urbanização de Interesse Social (2009):

AUTORES | AUTHORS: Profª. Dra. Simone Zarpelon Leão, Prof. Dr. Benamy Turkienicz
RESUMO | ABSTRACT: An analysis of housing issues in the city of Canela has been made in 2008 as part of the development of the Master Plan for Housing. The present paper deals with one component of this analysis, which is the assessment of urban accessibility for low-income population, and its consequences on the treatment of the problem of current shortage of low-income housing and the future demand from population growth until 2020. A three steps method is applied: (i) urban mobility is assessed and mapped on the basis of the road system and the routes of public transport; (ii) accessibility to different urban services are measured and mapped considering the location of urban facilities, population distribution divided by income and age, and urban mobility; (iii) one map for urban accessibility is produced as a result of the weighted combination of accessibility to different urban facilities. This final urban accessibility map is then overlayed to empty urban lots with size and land value appropriate to low-income housing, and a simulation of their development over the future has been made. The lots with higher accessibility were selected, and the impact of urban development was assessed on the capacity of education facilities. Based on this study, we made some preliminary suggestions for widening places in some schools, the need for a new education facility (location and size) and the extension of public transport for an area with low accessibility.

A Grammar-Based System for the Participatory Design of Urban Structures (2009):

AUTORES | AUTHORS: Martina Jacobi, Jan Halatsch, Antje Kunze, Gerhard Schmitt, Prof. Dr. Benamy Turkienicz.
RESUMO | ABSTRACT: We propose a three-step participatory design cycle for the early urban design phase that can be integrated into the digital design chain. Step one involves a visualization method that is implemented as an interactive card-based interview technique for the collaborative requirement specification of urban designs. In step two these specifications are a) translated into simplified GIS data and then b) implemented into a grammar-based system together with the corresponding design regulations. The final outcome is a generative and iterative urban model, which includes buildings, building blocks, transportation networks and open spaces that visually communicates spatial impacts of urban design proposals.

CityZoom: A Visualization Tool for the Assessment of Planning Regulations (2008):

AUTORES | AUTHORS: Prof. Dr. Benamy Turkienicz, Bárbara Bellaver Gonçalves, Pablo Grazziotin
RESUMO | ABSTRACT: A city modelled according to planning regulations usually presents a correlation between plots and building dimensions. To simulate the overall impact of building regulations over a large number of plots it is advantageous to use a computational tool to perform the task. Existing software can generate proxies of the would be reality, but do not accurately simulate the impact of alternative urban regulations. CityZoom is a Decision Support System for urban planning which not only provides CAD tools, but also allows users to evaluate and modify the city model according to different constraints such as solar radiation, luminance, terrain's pervious conditions, etc.. By simulating specific urban regulations and addressing environmental comfort issues, CityZoom helps architects to simultaneously evaluate the different attributes of a particular design. Coupled with GIS tools, CityZoom allows users to perform multiple analyses over the existing database and use the resultant feedback to optimize proposed solutions. Future developments envisage giving CityZoom a more autonomous role, using artificial intelligence to optimize building shapes and dimensions.

Participative Master Plans in Brazil: a new forum to discuss sustainable urban water management (2008):

AUTORES | AUTHORS: Prof. Dr. Joel Avruch Goldenfum, André Luiz Lopes da Silveira, Alfonso Risso, Gino Roberto Gehling, Prof. Dr. Benamy Turkienicz.
RESUMO | ABSTRACT: Nowadays, in Brazil, there is still great opposition to the adoption of sustainable urban water management concepts, mainly because of lack of knowledge on infiltration and storage devices. A new Brazilian legislation regulates and enforces the development of Participative Urban Master Plans, comprising several Public Enquiries and Meetings with different sectors of the society. The participation of urban water professionals in the development of these Master Plans can allow spreading the sustainable urban water management concepts. The present paper describes the main issues of Participative Master Plans in Brazil and presents the experience of a multidisciplinary team on their development, evaluating their possible role on the transference and dissemination of the sustainability concepts applied to urban waters integrated management. A methodology developed by this multidisciplinary team was applied to four cities and towns in the Rio Grande do Sul State, providing opportunity to introduce the sustainable urban waters management concepts to local communities' representatives, public managers and legislators. The response from these different sectors of the society was always very positive, contributing for the adoption of the new presented concepts and building a solid base for its effective implementation.

Cityzoom - a tool for the visualization of the impact of Urban Regulations (2004):

AUTORES | AUTHORS: Pablo C. Grazziotin, Benamy Turkienicz, Luciano Sclovsky, Carla M. D. S. Freitas.
RESUMO | ABSTRACT: Visualization has been used for many years as an important way of presenting architectural design and projects. However, beyond design, planning urban areas requires the analysis of different factors. Urban regulations are planning tools used to control and/or stimulate changes in the urban structure and to reproduce a certain level of quality of the urban milieu. Land area, built area, plot rate, average building height, and other important attributes can be easily obtained from the geometric objects in the city model or explicitly associated to them. This paper presents a system, CityZoom, which integrates several performance tools that allow the simulation of different attributes related to a planned or existing city. These attributes are shown in different ways either as tables of attribute values estimated from model evaluation, or 3D scenarios where the user can navigate and observe realistic shadows and daylighting estimation based on the concept of solar envelope.

Visualization Techniques in a Building Potential Simulator Using Sunlight Access Control:

AUTORES | AUTHORS: Pablo Colossi Grazziotin, Prof. Dr. Benamy Turkienicz, Carla M. Dal Sasso Freitas, Fernando O. Ruttkay Pereira.
RESUMO | ABSTRACT: This paper presents the use of a technique known as solar envelope in the simulation of building potential of urban plots as well as the improvement of 2D and 3D visualization techniques of simulation results. The consideration of sunlight access in urban planning fulfills basic requirements for improving the quality of buildings regarding thermal comfort. The work has improved an existing decision support system, CityZoom, which provides an environment where several performance models can be used in an integrated way for urban planning. One of these models is BlockMagic, where insolation can be simulated along with Master Plans rules, seeking to maximize both building potential and sunlight access. Besides the adoption of the solar envelope concept in the simulation, 2D and 3D visualization techniques were developed in order to show sun-path diagram, sky vault obstruction due to neighboring buildings, and 3D view with shadows obtained from the buildings simulation.

A methodology for sunlight urban planning: a computer-based solar and sky vault obstruction analysis (2001):

AUTORES | AUTHORS: Fernando Oscar RuttkayPereira, Carlos Alejandro NomeSilva, Prof. Dr. Benamy Turkienicz.
RESUMO | ABSTRACT: The main purpose of the present study is to describe a planning methodology to improve the quality of the built environment based on the rational control of solar radiation and the view of the sky vault. The main criterion used to control the access and obstruction of solar radiation was the concept of desirability and undesirability of solar radiation. A case study for implementing the proposed methodology is developed. Although needing further developments to find its way into regulations and practical applications, the methodology has shown a strong potential to deal with an aspect that otherwise would be almost impossible.
