title: Resilience in social housing developments through post-occupancy evaluation and co-production

description: Abstract The poor initial resilience of the ground-breaking Brazilian urban social housing programme ‘Minha Casa, Minha Vida’(MCMV) affects millions of people, who have tried to adapt their homes, survived the unexpected and have to reinvent themselves constantly. This study delimits the elements that compose the concept of resilience, namely: the impacts, vulnerabilities and adaptive capacities that characterize the resilience of the built environment in the case study selected. To achieve these aims, advanced Post-Occupancy Evaluation (POE) and Co-production techniques have been applied in the case study of a typical Brazilian MCMV development in Uberlandia (Brazil). The results highlighted factors going beyond the typical vulnerabilities already seen in most of these developments. They pointed out the adaptive recovery capacities as key factors for resilience. This case study provides the means to investigate resilience and its variables in depth within the specific context of MCMV’s social housing, subsidising designers and public policies makers in the elaboration of more resilient projects for these social housing communities.

title: Analysis of a standardized parameter for the design of wooden structures considering structural reliability

description: Abstract Reliability is related to the degree of reliability of a system, which must be established in the design, which should predict and specify itsoperating conditions. Annex E of standard NBR 7190:1997 for wooden structure projects presents results from a wide sampling of different dicotyledonous and coniferous species, with great variation in the number of specimens, fixing a coefficient of variation (CV) for normal and shear strength equal to 18% and 28%, respectively. This study evaluated, by using a probabilistic approach, the frequency distribution of samples of compressive strength parallel to the grain presented in the standard, seeking to specify the reliability index established. The results indicate that the data proposed may not be normally distributed, leading to distortions in the obtention of the characteristic strength. The adoption of a single coefficient of variation for the coniferous and dicotyledonous species is not ratified in the analysis of the data and, when considering the homogenisation of classes, different coefficients of variation are also generated. Regarding the proposed revision of NBR 7190, it is concluded that the inclusion of one more resistance class (D50) improves the distribution of the samples, however, the suppression of Annex E hinders the categorisation of classes by species.

title: Evaluating park usage through public health protocols: a comparative study

description: Abstract Many studies have been highlighting theimportant role of public spaces in supporting a healthier life. The aim of this research was to verify the existence of an association between the spatial configuration of parks located in different socioeconomic areas and physical activity. The methodological strategy used was a comparative case study in two urban parks in the city of Londrina, Paraná, Brazil. Two protocols were adopted, SOPARC (System for Observing Play and Recreation in Communities) and PARA (Physical Activity Resource Assessment), to collect data from users, activities, intensity of physical activity and the parks’ characteristics. The results indicate there is an association between facilities such as open-air gyms, hiking trails, sports fields, picnic areas and bleachersand the practice of moderate/vigorous physical activity. The analysis showed qualitative differences in terms of insertion, access, immediate surroundings and the parks’ different conditions. The results contribute to the establishment ofspatial guidelines in park designs, as well as topromote an interdisciplinary debate on the use of protocols validated and applied in the Health field.

title: Experimental appraisal for characterizing laboratorial and field performance parameters of pervious concrete pavement

description: Abstract Loratorial tests with pervious concrete comprised porosity and hydraulic conductivity as well as mechanical parameters as compressive, indirect tensile and bending strengths besides assessing its static and dynamic elasticity moduli. Later, a pervious sidewalk area of 1.0 x 8.65 square meters was built in order to determine the variation of the infiltration rate along time; over such experimental sidewalk, impact deflection tests performed allowed to assess back calculated moduli of the pervious concrete layer, resulting 33% to 13% lower than conventional concretes. A mechanistic analysis allowed to estimate the required thickness of concrete for heavy- and light-traffic areas. Tests disclosed no significant difference among the different concrete mixes, with 25% porosity and 0,1 cm/s permeability. Initial sidewalk infiltration rate of 0.5 cm/s dropped 50% four months after construction. It was verified that pervious concrete thicknesses for trucks and buses use are far higher than conventional concrete pavements.

title: Calcium hydroxide influence in autogenous self-healing of cement-based materials in various environmental conditions

description: Abstract Several factors, such as chemical shrinkage or environmental attack can produce concrete cracks. Calcium hydroxide content from the environment or cement hydration can promote the self-healing phenomenon (SHP). This study evaluates the calcium hydroxide concentration influence on the self-healing phenomenon of cement-based materials. Cracked mortars with different types of cement, such as a filler, pozzolanic, and high initial strength, were exposed to four environmental conditions. Titration was the method proposed to determine the amount of calcium hydroxide content leached in the water, and the cracks closure were analyzed by optical microscopy. CPII F (Portland Cement, type II, compound with limestone) samples showed no trend to Ca(OH)2 leached, and to superficial cracking closure. Regarding CPV (Portland cement, type V, high initial strength cement) samples, their behavior showed the highest Ca(OH)2 content to all environmental exposure, and cracking closure to samples in submerged condition. Thus, a significant influence in the cracks´ closure regarding the presence of Ca2+ leached to the exposure environments, and a water source related to this behavior seems to be a primary factor to improve the SHP.

title: Influence of ceramic block geometry and mortar coating on the sound reduction of walls

description: Abstract The materials that compose a construction system influence directly the acoustic performance of buildings.In masonry systems, through experiments, the geometry of the blocks and the types of coating were perceived as fundamental factors on the acoustic performance of walls. Therefore, this study intends to enrich the database and promote analysis for the civil construction industry by evaluating the airborne sound reduction of masonry walls composed by ceramic blocks with and without mortar coating. Accordingly, different partitions made of different ceramic blocks were built to determine the performance discrepancies in the partitions’ behavior due to physical characteristics and the influence of the mortar coating. These analyses were made in laboratory. As a result, without coating, the highest sound reduction was observed in the samples with more bulk mass and higher Aliq/At ratio (relationship between the net and gross areas of the ceramic blocks). Then, with the mortar coating, the coating improved the sound reduction. Moreover, the bulk mass was the most influential characteristic in comparison to the Aliq/At ratio, even though the best results were obtained in the samples with higher Aliq/At ratios.

title: Information workflow proposal for integrating cost estimating, scheduling, and monitoring with BIM in SMEs

description: Abstract Although many studies have emphasized the benefits of the integration of Building Information Modeling (BIM), there is no consensus on the information workflow among main processes used in construction, particularly in small- and medium-size enterprises (SMEs). Therefore, this work proposes an information workflow that integrates 3D BIM modeling, cost estimating, scheduling, and monitoring processes in SMEs (ICSM Information Workflow). This research adopts the design science research approach, which includes (a) a literature review and a study of the information workflow among the processes, (b) a proposal of an information workflow based on certain assumptions for integration, (c) a participatory process for testing and adapting the proposed workflow, and (d) an evaluation of the proposed information workflow. The results indicate the participatory and cyclical processes that were proposed to define the work packages using a standard WBS and a database for information integration were the key for integrating people, technologies, and processes. The main contributions of this study are the proposal of an information workflow that integrates cost estimating, scheduling, and monitoring with BIM in SMEs, and the lessons learned based on the pilot test and evaluation of the ICSM Information Workflow in one of the two projects studied.

title: BIM maturity model for higher education institutions

description: Abstrac The literature presents several BIM maturity models for projects, organizations and individuals. However, there is still a gap in models for Higher Education Institutions (HEIs). Consequently, there is an absence of studies that measure the BIM maturity of those institutions. Thus, the present study aims at (i) present a BIM maturity matrix model for HEIs; (ii) perform the measurement of BIM maturity in the HEIs in the state of Ceará, Brazil. The developed model is structured into three BIM fields (Policies, Processes and Technology), through 16 criteria and divided into five maturity levels. This research analyzed 26 courses in Civil Engineering as well as Architecture and Urbanism, in both public and private HEIs, therefore obtaining the Degree of Maturity, the Maturity Index, as well as the characteristics of BIM use. As a contribution, the study presents: (i) a theoretical contribution through the proposal of a BIM maturity model for HEIs, allowing other institutions to measure their performance; (ii) BIM characterization in HEIs, as well as the barriers for its adoption, uses and BIM disciplines; (iii) measurement of HEIs' maturity. The measurement of BIM maturity in the HEIs in Ceará state allowed an overview of them, becoming part of a macro-diagnostic state in the sector.

title: Evaluation of capabilities of different global sensitivity analysis techniques for building energy simulation: experiment on design variables

description: Abstract The objective of this study is to investigate the capabilities of different global sensitivity analysis methods applied to building performance simulation, i.e. Morris, Monte Carlo, Design of Experiments, and Sobol methods. A single-zone commercial building located in Florianópolis, southern Brazil, was used as a case study. Fifteen inputs related to design variables were considered, such as thermal properties of the construction envelope, solar orientation, and fenestration characteristics. The performance measures were the annual heating and cooling loads. It was found that each method can provide different visual capabilities and measures of interpretation, but, in general, there was little difference in showing the most influent and least influent variables. For the heating loads, the thermal transmittances were the most influent variables, while for the cooling loads, the solar absorptances stood out. The Morris method showed to be the most feasible method due to its simplicity and low computational cost. However, as the building simulation model is still complex and non-linear, the variance-based method such as the Sobol is still necessary for general purposes.

title: Determining the flow rate for choosing water meters of residential buildings with individual metering

description: Abstract The implementation of the individual measurement system requires the correct adjustment of the water meters. Thus, the determination of project flow rates is one of the premises for proper system performance. From this point of view, this article aims to compare the design flow values with the flow values obtained in apartments in operation. An investigation was carried out into 20 housing units, in which the flows were identified and their water consumption profiles and the actual flow distribution over time defined. We compared the flows calculated by the method proposed by Gonçalves (1986) in addition to the methods used in the Brazilian, Portuguese and European standards with the actual flows measured and indicated in a technical standard, using descriptive statistics techniques and using probabilistic data modeling. It was possible to verify that the values derived from the probabilistic method were the closest to the real measurements. It was concluded that the use of probabilistic method reduces the nominal flow of the chosen water meters, which can increase the accuracy and, consequently, the measured volume for the local utility. It also contributed to improve the procedures for assessing the design of water meters.

title: Multi-objective optimization of the geometry of single-family housing to improve thermal performance

description: Abstract Brazil's current housing deficit exceeds 6 million homes and a demand of 10 million homes for low-income families is expected by 2040. On the other hand, during the last 10 years, approximately 850,000 social housing units have been delivered through the "My House, My Life" Program - (Programa Minha Casa, Minha Vida - PMCMV). Despite these numbers, several studies suggest some problems related to the low quality of the houses. This article aims to investigate the design parameter related to the geometry of social housing in Chapecó/SC, Brazil, which contributes to the achievement of the best thermal performance. Parametric methods and multi-objective optimizations were utilized, two objective-functions were optimized regarding the degree-hours for cooling and heating. The results showed significant improvements, reaching up to 98% during the hot period and 49% during the cold period. Guidelines were defined to assist architects in the early-phases of the social housing design based on the climate of the target region. However, the best design solutions for thermal comfort throughout the year can only be indicated with computational methods.

title: Natural ventilation for office building retrofit in dense urban context under hot and humid climate

description: Abstract Recent studies underline that simple and non-invasive retrofit solutions can recover natural ventilation potential in existing buildings under temperate climate. Nonetheless, the efficiency of these solutions in dense urban contexts under hot and humid climate remains unclear. This paper aims to evaluate the thermal comfort gains caused by natural ventilation when retrofitting an office building in downtown Rio de Janeiro. Computational Fluid Dynamics (CFD) and thermal simulations are carried out on Ansys CFX and Design builder to assess indoor air flow before and after retrofit. The diagnosis of the current scenario indicates that the surrounding buildings block a significant part of the wind flow, and occupants experience only a few hours of thermal comfort during the year, especially on lower floors. To increase indoor air flow, the fixed upper windows were transformed into pivot windows and kept open permanently. This measure increases the annual hours of thermal comfort by 0.5-35%, depending on the floor and the adaptive comfort model. These findings suggest that natural ventilation itself may not be sufficient to ensure occupants' comfort throughout the year under the investigated context.

title: What has driven the growth of Brazil´s residential electricity consumption during the last 19 years? An index decomposition analysis

description: Abstract Residential electricity consumption in Brazil has been growing during the last few decades, creating a potential opportunity to expand energy efficiency measures. However, the dimension of the sector and its closed relationship with the economic, cultural, and demographic processes causes a certain complexity in the understanding of patterns of consumption, creating additional challenges to energy policies. This study analyzed and decomposed the Brazilian residential electricity consumption between the years of 2000 and 2018, by driving factors through the LMDI-I method and IDA index, on regional level. All the data were obtained by official sources in the country. The main results obtained were: (i) the increase of household numbers was found to be one of the main drivers of consumption growth; (ii) household income showed no control over consumption in hot climate regions, except in low- income households; (iii) tariff showed to impose restrictions on consumption, also mainly in low-income households. Unprecedentedly, the results showed that the electricity consumption in Brazil varies with population age, with a trend of consumption growth up to the age 59, and a sharp reduction from the age of 60. The study presents opportunities to be contemplated in research and in energy policies.

title: Evaluation of the performance of plumbing fixtures in public sports facilities in Brazil

description: Abstract The performance of plumbing systems is directly related to water and energy consumption. Malfunction of components in these systems can cause water waste and discomfort to users. In this research, the performance of 607 plumbing fixtures was investigated in five public buildings focused on sports activities in the city of Joinville, Southern Brazil. The flow rates and leaks in all installed plumbing fixtures were verified. The measured flow rate values were compared to those established by Brazilian standards and by environmental certifications LEED and AQUA. Flow rates of showers with water at 40°±2 °C were measured in summer and winter to compare the performance of showers in different seasons. The flow rates in showers displayed worse performance in winter than in summer. Also, 30.9% of taps showed some type of leak and 77.8% of toilets trickled. Of all plumbing fixtures, 71.7% presented some kind of defect. The results presented in this study indicate the main problems related to the performance of plumbing fixtures installed in public sports facilities in Joinville and can be useful in planning building preventive maintenance and water conservation actions.

title: Aspects impacting on the energy performance of Brazilian social housing: a literature review

description: Abstract In the last ten years, the social housing sector in Brazil has been driven by the Programme “Minha Casa, Minha Vida” (“My House, My Life”). Although the Programme allowed the construction of a great number of dwellings throughout the country, field assessments have highlighted failures such as lack of climate suitability. Such an inadequacy can result in low levels of energy efficiency and the dissatisfaction of residents. Thus, the aim of this study is to review the national literature from the last ten years (from 2009 up to 2019) in order to determine the most impacting parameters for the energy efficiency of social housing. A synthesis of this information is necessary to consolidate the knowledge produced so far and to facilitate progress in this area. This study is expected to help future decisions by different stakeholders: researchers can define future goals by considering what has already been done, designers can apply user-centric design and energy efficiency criteria in practice, and policy makers can link the approval of social housing designs to energy efficiency parameters.
