This work involves experiments using subroutines developed by the author in Fortran language to calculate heat and mass transfer, and ventilation. The simulations were done to check the results of the influence of the application of different materials on a flat roof associated to passive ventilation. The target of this paper is to evaluate the use of subroutines developed to show air temperature changes, the heat transfer through a flat roof and the ventilation on a small prototype. The experiments conducted involved predictable results and that is exactly why they were suitable to check the performance of the subroutine. It is relevant to mention that the heat transfer through a flat roof was checked including a solar gain factor, which changes during the simulation using the subroutines, according to the hour of day (hourly from 7a.m. to 5p.m). The analysis started by solving the air-circulation problem to determine the wind fields, using a mixed stabilized finite element method, like Petrov-Galerkin, applied to the full Navier-Stokes equations. The thermal problem is analyzed through the SUPG - Streamline Up-wind Petrov-Galerkin stabilized finite element method. Computational simulations allow for testing low cost operational interferences before implementing a project. © Copyright 2017 NCEUB.

This study aimed to evaluate the EDC （endocrine disruptors compounds） in the city of Sao Paulo＇s water sources, from samples collected at predetermined sampling points and to evaluate the adsorptive capacity of these compounds in different types of activated carbon. The effects of these EDC on humans are not well established due to the necessary large exposure time for the effect＇s manifestation. After tests using powdered and granular activated carbon, all samples were filtered under vacuum using cellulose acetate membrane （0.45 μm） to remove eventual impurities, and posteriorly carded out the solid-phase extraction SPE （solid-phase extraction） and chromatographic analysis. The results lead to the conclusion that both powdered activated carbon have removal effectiveness of these compounds by adsorption. Furthermore, great amount of endocrine disruptors were found at several sampling points in river and city＇s water reservoirs, which shows different levels of pollution of water sources, some of them responsible for the watersupply of the city of Silo Paulo, Brazil.

This paper aims to discuss how the shaping of a city, Juiz de Fora, in Brazil, has resulted from the power of location of some social agents and from their disputes on the production of space. First, it introduces the concept of social production of space, emphasizing the role of social agents in urban processes. Then, it presents specific aspects of the history of Juiz de Fora＂ its origins and how social agents and forces have played a significant role in shaping the built environment of the city--specially represented by main streets of the city. The paper studies how the social agents, with their different visions and goals, have influenced the process of formation and development of the city. This demonstrates the complexity of the existing relationships between the built environment and the social context that is specific to the city. Different urban forces fight for city spaces, construct and modify its territory so that their needs are fulfilled. Their strength, their experiences and efforts, and their ideas of a city are inscribed in urban landscapes; in similar ways, these are revealed by the city paths we follow here.

Post-Graduate Program in Structures and Civil Construction Civil and Environmental Engineering Department University of Brasília Campus Universitário Darcy Ribeiro Asa Norte Brasília 70910-900 DF Brazil Faculty of Architecture and Urbanism University of Brasília Campus Universitário Darcy Ribeiro Asa Norte Brasília 70910-900 DF Brazil

The ceramic coating systems applied to building facades have relevant aesthetic value and protection functions. The architectural and environmental conditions can greatly influence the degradation process of the facades, which may pose risks and compromise the durability and service life of the building and its components. The degradation process of facades changes according to the region where it takes place. To this end, the present study aims to determine damage intensity and distribution in the different regions of the facade. This study investigated the facades of three buildings that are part of the Materials Testing Laboratory (LEM) database of the Universidade de Brasilia. The degradation was quantified using a methodology proposed by Silva (2014) to generate a degradation index expressed in m². After the quantification of damages, few indexes associated with the percentage of degraded area, applied to the facade regions, are presented. These weighted indexes allowed to standardize the values observed in each region. Obtaining these indices is fundamental to the study of degradation. The results show that for a comparative analysis between the regions, the observed values should be corrected for the proportionality of the area of each region in relation to the total area of the facade. It was also noted that the continuous walls are the most affected regions, but they do not always present the highest damage intensity. © 2016, Springer International Publishing Switzerland.

Journal of Building Pathology and Rehabilitation 2016年第1期1卷 1-7页

作者： Nascimento, M.L.M. Bauer, E. de Souza, J.S. Zanoni, V.A.G. Post-Graduate Program in Structures and Civil Construction Civil and Environmental Engineering Department University of Brasília Campus Universitário Darcy Ribeiro Asa Norte Brasília 70910-900 DF Brazil Faculty of Architecture and Urbanism University of Brasília Campus Universitário Darcy Ribeiro Asa Norte Brasília 70910-900 DF Brazil

The association of rain and wind composes wind-driven rain (WDR), and its incidence may be crucial to the emergence of anomalies on the facades of buildings. Moisture from the WDR can influence the humidification and drying process, therefore the durability and hygrothermal performance are conditioned by the amount of incident water. The quantification of WDR can be an indispensable tool for understanding its related phenomena and the service life of buildings. The most widely used methods of quantification are the semi-empirical, with theoretical basis, but coefficients partially determined from measurements. These methods may take into account the building exposure conditions related to the envelope, solar orientation, height of the building, and other parameters. In this context, in order to contribute to the studies on quantification of WDR, the purpose of this paper is to apply hygrothermal simulation software WUFI^® on quantification of WDR focusing on buildings degradation of Brasília-Brazil. For the simulation it was used a Typical Meteorological Year file with the wind and precipitation measurement data indispensable for simulation. The quantification of incidence of WDR considered the orientations North, Northeast, East, Southeast, South, Southwest, West, and Northwest. The use of semi-empirical WUFI^® quantification method allowed finding the highest values and consequently critical orientations North, Northwest, and Northeast, moreover, this results showed the relation with the degradation of facades in these orientations. WUFI proved to be an easy, fast and efficient method of WDR quantification, without hiding seasonal weather effects. © 2016, Springer International Publishing Switzerland.

The risk of natural disaster has been the focus of public policies. They are based on the Federal Law 12.608 / 2012, establishing the National Policy on Protection and Civil Defense. The overall goal is to understand the public policy related to the risks of natural disasters in the city of Blumenau, by identifying the structure of a public body and its powers. It constitutes an exploratory and descriptive qualitative approach. The method is characterized by systemic method and indirect technical documentation. The research was done in three steps: data collection, tabulation of information, analysis and discussion of results. The results indicate that the Supplementary Law 870/2013 which defines the administrative structure of the public power of Blumenau, does not detail the powers to the municipal responsible body for risk management of natural disasters, precisely indicated in Federal Law 12.608 / 2012.

Expansion of Logistics Capability in Emergency Care Systems with Growing Demand

引用

Procedia - Social and Behavioral Sciences 2014年 160卷 15-24页

作者： João Carlos Souza Pos Graduate Program in Architecture and Urbanism Department of Architecture and Urbanism Federal University of Santa Catarina- 88040-900–Campus Universitário da Trindade - Florianópolis SC Brasil

Due to increase in population, income, or gross domestic product in the country, several systems that require fixed installations for user assistance, such as telephone and power services, port terminals, schools, water supply, among other, are subject to increased demand over time. Thus, the supply of services tends to undergo a process of saturation, and that will eventually create a need to expand their facilities over time. Emergency care services, such as firefighters, ambulance service, police, transport of organs for transplantation, etc., can also face this same problem of excessive demand over time, up until they are not able to assist the population properly. The objective of this study is to determine the optimal time interval for the inclusion of new bases for the Fire Department in the city of Florianópolis, SC, Brazil. So as to minimize the cost of the current amount needed to provide future capabilities or to make the average waiting time to assist citizens affected by some emergency situation the shortest possible. New facilities are presumed to be added to the system capacity as soon as it reaches the point of saturation or when the average waiting time in the queue for assistance exceeds a maximum due time established according to the growing demand for services. The cost of unmet demand is not included in this study.

The author knows how to interpret the city is a complex task that met the physical form and also all the images that are transmitted by the sensations. However the aim of this paper is to demonstrate the importance of studying the morphological categories, using the geometric attributes of the shape of places, facilitating the development of three-dimensional view of the architects, in particular for students of architecture. This article is part of the Project ＂Education of the Eye＂ which introduces the training of the eye as a strategy to understand the architectural forms characterizing the volumetric space （architectural, urban and landscaping）, through the polyhedra and their relationships. It is linked to the research line Teaching of architecture graduate program in architecture -- PROARQ-FAU/UFRJ. The investigation of the way in this direction, interacts with the knowledge produced by the groups SEL-RJ -- Research Group on Systems of Open Spaces in Rio de Janeiro, ProLUGAR -- Design and Quality of Place and EAG-Education-Environment Group.

Aiming to study the temperature field changes, the House VI project was checked. This house is located in Vila37, Rio de Janeiro, Brazil, a dead-end small street with only one inlet/outlet. In the houses of Vila37, the indoor ventilation is restricted to the facade windows. Giving the impossibility of introducing cross-ventilation in a traditional way, a short wind-catch was previously added with positive results;therefore, simulations with long wind-catch are being carried out. The analysis started by solving the air-circulation problem by using a finite element method and after, with the wind fields added, the heat transfer problem was analysed. The results obtained were evaluated and compared with the previous ones.

Electronic Journal of Information Technology in Construction 2007年 12卷 193-206页

IT application in emerging countries faces many specific constraints, not only in infrastructure but also from cultural and economic differences. In Brazil, despite quite satisfactory IT technical education with qualified staff, we have encountered AEC professionals with insufficiently well-developed IT skills, except in CAD systems. This has contributed to a full range of potential IT uses not being considered by the large majority of companies. Most of these companies are small and medium-sized organizations, with limited budgets and technical capacity. The greater part of the market happens to be outside the regulatory context and so, they are not particularly concerned with quality and productivity. The construction sector scenario is therefore reflected in the IT companies, the majority of which are small companies developing customized proprietary systems, thus creating inter-operability difficulties. On the other hand, only a few large contractors have begun to use ERP systems, due to the financial investment and time required to implement them. Besides these barriers, some other factors are also pushing the envelope, requiring more intensive IT use. This is mainly as a response to the formal competitive market that requires quality systems and new trends in documentation and management. To overcome these difficulties some urgent actions have been listed: i.e. improvements in IT education for AEC professionals and cooperative development programs for IT and construction companies.
