The use of underground spaces has been pointed out as an alternative to the growing demand for more areas in cities and the presence of natural light is seen as a strategy for improving the quality of such buildings. Light pipes are one of the technologies capable of conducting light over long distances. However, they require local studies to check the most efficient performance in each geographical location. This paper aims to study the performance of a given light pipe combined with a heliostat device in Porto Alegre, a city in south Brazil. We conducted an experiment in which scale models were used. Different reflexive materials were tested and, as a second step, light pipes combined with the use of a handmade heliostat were verified. At the end, rapid prototyping tools where used to build and test an automatized heliostat. Our results pointed to a great potential for using these technologies in deep environments on cloudless days. However, in overcast weather their efficiency drops considerably, so the use of hybrid systems may be an alternative. Heat load conduction and glaring caused by direct sunlight are some of the main limitations of these systems and must be addressed in future experiments. Copyright © NCEUB 2017.

Climate change affects all areas, including those with low temperature. Wonosobo belongs to highland areas with low temperature. The thermal performance of buildings is influenced by micro-environment climate so that the climate change will affect the thermal performance of buildings. Vernacular buildings are believed to be able to make the occupants comfortable. The vernacular buildings in tropical highlands have either exposed stone walls or wooden walls. The present research seeks to analyze the thermal performance of building envelopes with wooden walls and exposed stone walls in highland areas. Simulation method using the Ecotect software was applied. There are 12 building models with a variety of roofing and flooring were selected. The results of the simulation indicate that the difference between indoor and outdoor temperatures of one model and other models is not significant. Warm temperature mostly occurs in houses with exposed stone walls. Highland areas need much warmth so that cold temperature will not disturb occupants.

This paper discusses the result of the study on plant diversity in the Agroforestry system and its traditional uses by the three different ethnicities in Banggai Regency, Central Sulawesi, Indonesia. The basic data of traditional plants used by each of the ethnic groups in the research site wer collected through an in-depth interview initiated by an informed consent using a questionnaire containing open-ended questions—fifty (50) respondents from each of the ethnic groups representing different jobs. The result showed that the highest number of plant species was found in research site B, bu the highest number of individual plants was noted in research site A. The highest Important Value Index (IVI) of tree, poles, sapling a,nd seedling level of plant species differed among the three research sites. When viewed from the perspective of traditional plant use, the highest ICS of plants utilized by the three ethnics was 'coconut' (Cocos Nucifera L). The number ofthe utiliplantslant was different among the three ethnics. Tao Taa Wana people have utilized about 43 plant species, 27 of which were used for medicines, 20 for foods, 2 for natural dying, 18 for fuels, 6 for building materials, 5 for ritraditionaluonal ceremonies. In research site B (Singkoyo), 52 plant spe es have been extensively used by Javanese people for a wide range of culturally related activities, 28 species were used as medicine, 32 for food, 17 for fuel, 7 for building materials, and 10 for ornaments. Unlikely, in site C (Mentawa, 39 plant species were used traditionally by Balinese people; 18 of which were used for medicines, 18 for food, and 13 for ritual ceremonies).

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.

The present study aims to evaluate the environmental effect on fungal community composition associated with biodeterioration occurring in stones （soapstone） at two distinct locations in Minas Gerais State, Brazil： Congonhas city and Sanctuary of Cara^a. Four collections of fungal communities over one year were obtained from both research sites from the soapstone block surfaces exposed for over two decades. The molecular diversity profile of the fungal community at the two localities was obtained by DGGE （Denaturing Gradient Gel Electrophoresis）, and the genomes of the most representative population were sequenced. DGGE showed the formation of two clusters with filamentous fungal communities. Sequencing of the most representative bands revealed the presence of fungi associated with the biodeterioration of soapstone. In addition, many of the identified species were associated with photobionts that could generate lichens, indicating that environmental characteristics affect the occurrence of filamentous fungi, which leads to biodeterioration of stones. Authors＇ study focused on an environmental variation of an extreme habitat for fungi associated with soapstone in the state of Minas Gerais, Brazil and identified the presence of interesting rock-inhabiting fungal communities including species related to lichens, which can accelerate the deterioration of stones by the production of organic acids.

Journal of Building Pathology and Rehabilitation 2016年第1期1卷 1-9页

作者： de Souza, Jessica S. Bauer, Elton Nascimento, Matheus L. M. Capuzzo, Valdirene M. S. Zanoni, Vanda 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 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.

Palembang City development since the Palembang Darussalam Sultanate era to the reformation era has impact on the living culture community, less of the raft houses, houses on stilts transformed into a terraced house, and the house became the dominant land. Dwelling Culture oriented on transformation of river become land-oriented. The development has leaving identity, character, and potential of the riverine architecture and dwelling life of river. The goals of study are to describe a case and revealing the meaning of dwelling cultural transformation in Musi River society from the process of cultural acculturation and investigate the architectural aspect from the form of house and modes of dwelling through the structuralism approach. The data collection is conducted qualitatively by using data collection techniques such as observation, interview, literature study, whereas the method of analysis, is a method that is done through Levi-Strauss structuralism approach that identifies all the elements of community thought in a systematic procedure. The results showed the structure behind the orientation, position, shape, and layout of dwelling revealed through the meanings in it. It means, the change and development from cultural acculturation process which oriented in the land dwelling, based on structure thinking of Palembang society.
