title: The impact of the urban canyon geometry in the nocturnal heat island intensity: analysis by a simplified model adapted to a GIS

description: Abstract Urban geometry is one of the main factors influencing the development of urban heat islands. The study of urban geometry requires a characterization of urban canyons, which can be usually measured by the H/W ratio (a relationship between the height and the width of a street), a concept applied in a numerical model by Oke in 1981. The aim of this paper is to verify the impact of the canyon geometry on the intensity of the nocturnal urban heat islands. For this purpose, measurements of climate data and urban geometry were conducted in two Brazilian cities. The values of heat island intensity were cross-examined to those generated with the application of the original Oke's model. Therefore, this latter was calibrated and adapted to run in a GIS platform, allowing the incorporation of a geometric parameter other than the H/W ratio - the roughness length. Then, this process produced a new calculation tool, which is called THIS (Tool for Heat Island Simulation). The new model was applied to simulate some hypothetical urban scenarios representing several urban canyons types. The results showed that the urban canyons with the largest roughness reduce the nocturnal heat island intensities in relation to an urban canyon of the same H/W value, but presenting lower roughness rates instead.

title: Impacts of changes in surface albedo on microclimate and pedestrian thermal comfort levels in urban canyons

description: Abstract Urban surface albedo is directly related to their ability to absorb energy or reflecting it to the adjacent surfaces, affecting the microclimatic conditions and thermal comfort in the pedestrian level in open space. The aim of this paper is to analyse the influence of changes in albedo of urban surfaces on canyon air temperature and on pedestrian thermal comfort, for mid-sized cities located in the eight Brazilian bioclimatic zones. For this purpose the predictive model canyon air temperature (CAT) and the comfort index ITS have been used. Results showed that impact of changing from low to high surface albedo is negligible for air temperatures whereas an increase of surface albedo tends to worsen thermal comfort conditions at the pedestrian level. Therefore, the use of high albedo should not be prescribed to canyon surfaces indiscriminately, as it requires an assessment of local conditions in order to identify which surfaces have enough solar exposure for an effective use of higher albedo, without negatively affecting pedestrian thermal comfort.

title: Influence of the addition of "synthetic termite saliva" in the compressive strength and water absorption of compacted soil-cement

description: Abstract The aim of this paper is to determine the effect of adding 0.1 wt% of "synthetic termite saliva" on a fine and clayey sand latosol (76.5% sand) from the region of Bauru, SP (Brazil), stabilized with 1% to 3% of cement. Compacted cylindrical specimens (with standard Proctor energy) were tested to determine their compressive strength and water absorption. The results indicate that the use of the chemical stabilizer increased by at least 35% the compressive strength and reduced by up to 13% the water absorption of the samples. This work contributes to efforts aimed at reducing the consumption of cement through the production of stabilized compressed earth blocks and bricks (CEB) and rammed earth.

title: Evaluation of the cooling potential of a roof-pond system under subtropical conditions

description: Abstract Indirect evaporative cooling systems (IECS), characterized by the use of wetted roof or wall surfaces for cooling without increasing the indoor air moisture, consist of an interesting bioclimatic strategy is still little explored in Brazil. The paper aims to evaluate the use of a particular form of IECS (which combines evaporative cooling and thermal mass brought about by a water reservoir) for indoor thermal control in warm conditions in Curitiba, located within Bioclimatic Zone 1. Two scale models were initially built, monitored and compared to each other: a control module (CM) and an experimental module (EM), the latter provided with an evaporative pond. A subsequent configuration of the system which cancels out the evaporative function of the system, based on the increase of the roof's thermal capacitance by an enclosed water container, was tested in a second monitoring round. Thus the results showed a higher effectiveness of the IECS for the indoor cooling of the tested scale-models.

title: Evaluation of mortar rheology, AAR and properties, in fresh state, using eucalyptus ash as partial replacement to Portland cement

description: Abstract According to the National Energy Balance (base year 2013), the national wood consumption was 79.29 million tons. It is estimated an ash generation in the order of 3% during this process, causing storage and disposal problems. Thus, the potential transformation of such waste into a source of raw material for construction elements is presented as an opportunity for the preservation of the environment and to reduce the cost of construction materials. The paper aims, therefore, to evaluate the feasibility of this reuse, through analyses of the properties of mortars in the fresh state, including rheology, using eucalyptus ash levels with 10%, 20% and 30% replacement, in weight, to Portland cement. Through the performed experiments it was found that the use of eucalyptus ash as partial replacement of cement does not significantly alter the properties of fresh mortars, presenting itself as a possible alternative.

title: The building information model in performance-based design: characterisation and process

description: Abstract The concern with building performance has gained prominence in Brazil and generated significant changes in the Architecture, Engineering and Construction (AEC) sector. Recent research studies have proposed the integration of performance analysis into the early stages of the design process, aiming to achievethe best final building performance. Choosing an adequate set of solutions and computer aided ways to develop them is a highly complex task, involving great responsibility. This study investigates the understanding of the technique and utilization of performance computational evaluation tools in the early stages of the design process. Hence, an exploratory study was undertaken in order to clarify the relationships between performance requirements, computer aided evaluation and decision-making in the promotion of solutions aimed at improving the final quality of the project. Through a field study, it was possible elucidate the information model and identify the parameters that come into direct confrontation with each other as they are being shared by one or more performances. The influence between the performances can be also analysed, resulting in the proposition of a simulation sequence methodology.

title: The "small" housing complex Cecap derivatives from Guarulhos and Jundiaí: a comparative analysis

description: Abstract The Housing Complex Zezinho Magalhães Prado in Guarulhos, SP, designed by Vilanova Artigas, Fábio Penteado and Paulo Mendes da Rocha, plays a seminal role project. Because of the sets development in the countryside, that followed the concepts applied in Guarulhos, the report verified to what extent have happened reproductions in sets of Jundiai, Marã Lia and Mogi-Guaçu, these on a smaller scale and in different contexts. The research also tried to verify the constant improvement of design solutions. Through the visits, the analysis of projects and information gathered, it was possible to identify elements in projects and constructed fact, which were graphically represented and gathered in comparative tables. The comparative analysis aimed to investigate the relationship between the projects and the construction of housing. The adoption of ramps in vertical movement, the group of buildings and the scale reduction of housing are examples of design solutions that aimed to actual construction. The similarity between the sets of Jundiaí, Marília and Mogi-Guaçu reinforces the hypothesis of use of a model adequacy to place of deployment The detailed datas of "small" Cecap Marília and Mogi-Guaçu contributes to the dissemination of this importante period of the Brazilian architecture.

title: Parametric proposal for development of sustainable housing projects in BIM tool

description: Abstract Unstable Brazilian housing policies have been unable to provide adequate housing for the low-income population in Brazil (0 to 3 minimum wages), considering both quantitative and qualitative aspects. The housing proposals designed for this population seems to ignore the complexity involved housing when it comes to the cultural, individual and family aspects of users. As a way of promoting housing customization considering living habits and sustainability, this study aimed to develop a design method for social housing, associated with a virtual environment powered by design parameters. These parameters were collected from self-constructed dwellings, registered in a shape grammar and adjusted after considering "Blue House Seal" sustainability criteria. This research project is a qualitative and exploratory study, based on the Constructive Research approach. The work was divided into three stages: understanding, development and consolidation, with specific methodological tools for each step. The result is a plug-in, based on a BIM tool, for generating proposals for social housing, considering the parameters previously collected and adjusted.

title: Development of an Augmented Reality environment for the assembly of a precast wood-frame wall using the BIM model

description: Abstract This article presents the development of an Augmented Reality (AR) application to assist in the assembly of a precast wood-frame wall, based on the BIM model of the wall execution sequence. The research study used the Design Science Research approach and its aim was to develop an AR application named "montAR" (version 2.0). This application offers a tutorial that combines a wall model visualized in AR in actual scale, followed by an audio with step-by-step instructions of the assembly process. Its applicability was simulated in a laboratory with the participation of volunteers (architecture and engineering students). Two visualization gadgets were used and compared: smartphones and smart glasses. The potentialities and difficulties of the use of the AR system were assessed through a questionnaire answered by the participants and through direct observation and result analysis by the researchers. The results demonstrated the potential of using AR for precast wall assembly. From a technological innovation perspective, this study emphasizes the potential use of AR as a technology suitable for training and for construction quality control.

title: Digital fabrication in Brazil and the possibilities of paradigma shift in the building sector

description: Abstract This paper analyses the possibilities brought by new digital technologies, architectural design and production for a paradigm shift in the construction sector. The methodology proposes to use evolutionary economy theory, which sees innovation as a key agent for paradigm shifts, to visualise the connections between existing firms in the current paradigm and the connections that could be established for a new production paradigm through digital fabrication. In order to do this, the role of the university and its innovation potential will also be analysed, both to develop product technology and to contextualize the technology being imported into a regional context, developing an emancipatory production process for the construction industry.
