title: Field experiments with a roof pond and radiant cooling panels in a test building

description: Abstract Among the components of a passive building, the roof is particularly important for the regulation of internal thermal conditions. Among the passive cooling systems that act from the roof, we can mention the roof pond (RP). In turn, radiant panels that use water as fluid can achieve high energy efficiency, enhancing the performance of the cold supply source. However, studies on the joint application of these technologies are lacking. This research study aimed to evaluate the thermal performances of different RP configurations, with and without radiant panels, applied to a test building during the summer. The experiment took place at the Sde Boqer Campus, Ben-Gurion University of Negev, Israel. The test environment with a conventional local roof was used as a parameter for comparison. The thermal performance was evaluated using Standard 55 and EN 15251, stabilisation of internal temperatures, and cooling. Compared to the conventional roof, the RP presented good results in terms of the moderation of the thermal conditions of the test building, especially when considering the European standard EN 15251.

title: Comparative analysis of acoustic insulation in different building geometries: field tests and computer simulations

description: Abstract Currently in Brazil, residential buildings must be comply with basic acoustic insulation conditions, and in order to do that, the acoustic characteristics of the building system must be well known. For the design conditions, acoustic insulation data from laboratory tested systems are used as input values in computer simulations, thus estimating the results that can be obtained in field tests. This paper presents the results of air noise and standardised impact of different building systems tested in the same building, focusing on the comparative analysis of different areas and geometries and the estimation obtained from an acoustic prediction software. The tests were performed in residential buildings according to the technical standards ISO 16283-1 and ISO 16283-2 and estimated using the SONarchitect software. An analysis of measurement uncertainty from a historical data series was performed to verify whether geometry influences expanded uncertainty. It was verified that part of the air noise tests presented simulated results with smaller values than those found through the test, and measurement uncertainty tended to a higher value as the room volume increased. For the impact noise transmission tests, the estimated values were very close to the test results, however, it was not possible to relate the measurement uncertainty to the tested room volume.

title: Thermal perception in a room with radiant cooling panels coupled to a roof pond

description: Abstract Roof ponds (RP) can promote comfortable thermal conditions, particularly in single-storey buildings. They allow structural cooling or heating and the stabilisation of surface and air temperatures. When coupled to radiant panels cooled by the exposed pond, they can further improve their thermal performance. However, there is a lack of research on RP focusing on the thermal perception of users indoors. The main objective of this study was to verify, empirically, under summer conditions, the thermal perceptions of volunteer participants in an indoor environment conditioned by a system composed of radiant panels coupled to a RP. We also sought to identify which adaptive model best represents the thermal votes reported by the study participants. As parameters for analysis of reported thermal votes, the PMV model and the passive building model of ASHRAE Standard 55 and EN-15251 were employed. The experiment took place in a test building at Ben-Gurion University of Negev, Israel. The sample consisted of 46 volunteer participants. The RP environment was perceived as comfortable by most volunteers. The thermal votes showed more agreement with the PMV and EN 15251 models than with the ASHRAE model.

title: Guidelines for control of documented information generated by the implementation of NBR 15575: residential buildings: performance in construction companies

description: Abstract This paper presents the results of a research study aimed at proposing general guidelines for documented information control. That information is generated in the implementation process of Brazilian standard NBR 15575 in construction companies. The control is necessary to comply with the requirement 7.5 Documented information, of the Brazilian Habitat Quality and Productivity Program (PBQP-H) Regiment. The methodology adopted involved: 1) a bibliographic review on the themes "performance"; NBR 15575 and PBQP-H; 2) a case study was carried out in two companies, to identify which documents were being generated and how they were being controlled. The results pointed out several difficulties faced by companies, such as the existence of checklists that did not fulfill their role; different types of archived test reports; absence of definition of rules for control and distribution of information, among others. Based on these findings, guidelines are suggested to be followed in order to reduce these difficulties. A checklist with suggested deadlines for retaining records based on the Project Lifetime (VUP) of NBR 15575 is also proposed.

title: Monitoring and modelling the operation of internal shading devices in offices: a literature review

description: Abstract The influence of user behaviour on the performance of buildings has been discussed in the literature. Regarding the operation of non-automated internal blinds/shades in offices, it is up to the occupant to balance the use of daylight as well as the reduction of incident solar radiation by adjusting the internal blinds/shades throughout the occupied period. This study aims to review the national and international literature of the last ten years (from 2009 up to 2019) to summarise the knowledge produced so far regarding the monitoring and modelling of internal blinds/shades operation in offices. Several suitable methods have been identified to monitor users' behaviour; such methods result in both subjective (personal preferences) and objective (affecting environmental variables) information. The challenge in this area is to combine different information to model user behaviour realistically and accurately. It was concluded that advances in the monitoring and modelling of behaviours improve the practices of computer simulation and the development of user-centred building automation systems. Finally, it is noteworthy that continuously monitoring user behaviour patterns allows to obtain feedback on automated systems in order to enhance them during their lifespan.

title: Evaluation of thermal comfort and air changes in indoor environments with solar chimneys

description: Abstract The use of natural ventilation strategies to provide thermal comfort and air changes is necessary in most of the Brazilian territory. In this context, solar chimneys can promote benefits such as increase air changes and enhance the thermal comfort of building users. This paper aims to investigate the ability of a solar chimney model to provide thermal comfort and air changes in classrooms and offices. We ran two stages of energy performance simulations on EnergyPlus: the first stage evaluated parameters such as height, number of installed devices per room and solar orientation aimed at providing more hours of comfort and air renewal in four Brazilian cities; the second stage expanded the scope of the devices/rooms simulated to eight Brazilian cities. In the second evaluation, the variation of climate conditions had an impact of up to 80% on comfort hours. The influence of the devices led to an average increase of 28% in comfort in classrooms and 21% in offices. The air change rates were between 2.4 and 13.5 ACH. The best performances were observed in the cities in ZB1, ZB2, ZB3, ZB4, and ZB5, demonstrating the potential benefits using this solar chimney in those bioclimatic zones.

title: Unmanned Aerial Vehicles (UAV) for inspection of pathological manifestations on ceramic coated facades

description: Abstract The world is undergoing a revolution, with high demand for the use of technology in industrial processes notably due to the need for optimisation of time, which poses a significant challenge. Hence, unmanned aerial vehicles (UAVs) are becoming increasingly relevant as novel, more agile and secure devices.This study was aimed at performing an exploratory study of the use of UAVs as a tool for the visual inspection of pathological manifestations in building facades. The methodology included experimental research, where two case studies were carried out in buildings of medium and high height, developing for these purposes the protocol of activities, where the image collection and processing stages were contemplated. Thus, the results proved the technical feasibility and efficacy of the inspection, showing that among the visual assets produced, the digital photographs generated by the aircraft were more effective in detecting pathologies than the models generated by the Agisoft PhotoScan software. The main contribution of this study is the validation of the technological package designed to assist in the diagnosis of pathological manifestations based on the formulation of a protocol for facade inspections using UAVs and a comparative analysis of the visual assets that can be generated.

title: Free tool for sustainable design projects: case study on health research public laboratories

description: Abstract Health research laboratory buildings need to comply with building regulations and biosafety standards, according to the type of laboratory proposed. In Brazil, the Oswaldo Cruz Foundation (Fiocruz), a reference center in health research, has been developing projects that address issues related to sustainability. It has proven to be a difficult task to combine sustainability requirements for public buildings with biosafety requirements. This article aims to investigate the potential use of a free tool for assessing sustainability in the built environment of health research laboratory installations, which are usually located in public buildings, as well as to examine to what extent these installations meet biosafety requirements, through an evidence-based approach. In order to do this, the researchers used the case study of a design for a laboratory building of Fiocruz that must meet biological safety requirements of risk NB-3 and sustainability through the free evaluation SBTool. The resulting analysis matrix indicates that the dictates of biosafety bring restrictions to the design of the laboratory installations and still impose limitations for sustainability. Despite some restrictions, the proposed tool may reduce public spending on commercial certifications.

title: Research instruments on environmental quality applied to small children with Down Syndrome

description: Abstract Children aged between 4 to 7 years play a minor role in academic studies in Architecture and Urbanism, a situation related to the difficulty of obtaining their opinions, especially those with intellectual disabilities, such as Children with Down Syndrome (CDS). Therefore, little is known about their perception of the built environment. For this to change, instruments should be developed in order to approach these children, which could contribute both to valuing their opinion and supporting the professional practice of architects. This finding led to exploratory, qualitative and interdisciplinary research to create research tools directed to young CDS, and obtain their opinion about the built environment. The study was based on: (a) literature review; (b) expert panels, comprising 10 parents and 28 professionals. Based on this information, three research instruments were prepared: Spatial Qualification Chart, Illustrated Cards and Make-believe in a Three-Dimensional Physical Model. They are tested with eleven CDS. The results showed that: (i) the proposed instruments fit the task; (ii) some care can facilitate the work with this public; (iii) the participating children perceive and qualify the space - which justifies new research endeavors with CDS.

title: Digital image processing for automatic detection of cracks in buildings coatings

description: Abstract In the phase of diagnosis of pathological manifestations in facades, the visual inspection stage deserves special attention due to its inherent complexity (height, size, access difficulties and exposure conditions). In recent years, there has been a growing use of deep learning techniques to detect and classify specific features in images and videos, which, when combined with the use of unmanned aerial vehicles (UAVs) for capturing images, is a potentially useful tool to assist and automate the procedures of visual inspection of facades. This paper aims to perform an analysis of digital image processing for the automatic detection of cracks in ceramic tiles, associated with UAVs or drones, which could potentially bring benefits (time, cost and safety) to the diagnostic process. The research results demonstrated the technical feasibility of detecting cracks through PDI techniques, however, the procedure is a complex process when there is high variation in the study images. At the same time, even in case of a limiting scenario such as the lack of public datasets for the problem, this research project still managed to develop a simple and efficient methodology to deal with the issue proposed.

title: Behaviour assessment of ready-to-use mortar with waterproofing treatment with crystallizing admixtures

description: Abstract The presence of water in coating rendering mortar is the main cause of the onset and dissemination of pathological problems, compromising durability and the surface protection of walls under harsh weather. On the other hand, waterproofing treatments as crystallising admixtures are designed to create a barrier against water penetration. This research study assessed 36 hours’ and 72 hours’ ready-to-use mortars, with and without the application of crystallising admixtures (liquid and powder), in order to evaluate their behaviour in the presence of humidity in the liquid and vapour states. The mechanical strength and permeability were evaluated in hardened mortars. The conclusion was that the 36 h mortars had the best results. The treatment with crystallising admixtures reduced water absorption and increased mechanical strength. The liquid crystallising admixture proved to be more appropriate, since the powder crystallising admixture decreased vapour permeability, which causes damage to the coating.

title: Characterization and use of sugarcane bagasse ash in soil-cement bricks

description: Abstract In Brazil, the sugar and alcohol industries generate important products such as alcohol and sugar, and produce byproducts as sugarcane bagasse ash (SBAS). The SBAS has a high pozzolan content and can be applied as a partial cement substitute in the production of building materials. This study aims to characterise sugarcane bagasse ash and use it as a supplementary cementitious material in the production of soil-cement bricks. SBAS was used to replace the percentages of cement used in brick composition in the proportions of 10, 20 and 50% by mass. The chemical characterisation of SBAS indicated the presence of crystalline silica in the form of quartz and cristobalite. After partial replacement of cement by ash, the bricks preserved their compressive strength. Among the compositions studied, the partial replacement of cement by SBAS at 20% presented the highest compressive strength. The results showed that SBAS is a suitable byproduct for the manufacture of sustainable building materials.

title: Life cycle energy assessment and carbon dioxide emissions of wall systems for rural houses

description: Abstract Wall systems have a wide range of embodied energy due to the diversity of materials available. This paper analyzes the expenditure of energy and carbon dioxide emissions in internal and external wall systems (IEWS) of a rural residence of social interest in Cascavel, state of Paraná, Brazil. The methodology proposed by NBR ISO 14040 was used to perform a life-cycle energy assessment (LCEA) and the carbon dioxide emissions assessment (LCCO2A) of these systems. Four scenarios were considered: reinforced concrete structure and ceramic blocks wall system, load-bearing masonry with concrete blocks, steel framing and reinforced concrete walls molded on site. As a result, it was found that it is possible to reduce energy consumption up to 25% by opting for reinforced concrete walls molded on site. In regards to CO2 emission, it was verified that the difference is even greater, being able to reduce emissions by almost 32% when opting for this same scenario.

title: Estimation of strength and stiffness in compression parallel to the grain of Pinus sp. by colorimetry

description: Abstract Strength and stiffness properties of the wood, fundamental in a structural design, are determined based on mechanical tests. Among the mechanical properties of wood, the strength (f c0 ) and stiffness (E c0 ) to compression in the parallel direction to the grain. Color is a characteristic of each species. If the f c0 and E c0 properties of a wood species are determined experimentally, based on a significant number of characterized samples, the correlation of these properties through equations obtained by regression makes it possible to estimates of such properties without the need for new tests, a procedure with potential for application by companies of the wood industry. With the aid of the CIE L*a*b* system and 403 pieces of wood from Pinus sp. equations obtained by regression analysis were used to estimate the E c0 and f c0 as a function of colorimetric parameters and also the number of growth rings. From the estimate of E c0 (R 2 = 43.61%), by ANOVA of the regression equation, it was found significance only in the number of growth rings (Nle). For the compressive strength parallel to the grain (R 2 = 48.53%), only the colorimetric parameters and the interactions of these parameters significantly affected the f c0 .

title: Castor oil based polyurethane adhesive content on OSSB produced with soybean straw

description: Abstract Oriented Structural Straw Board (OSSB) panels are composites made from straw originally from agricultural residues and non-formaldehyde based adhesive, whose main application is for construction as a closing and ceiling material. The objective of this study was to evaluate the effect of the polyurethane adhesive content on physical and mechanical properties of OSSB produced with locally available SbS (soybean straw). Four castor oil based polyurethane ratios (6%, 9%, 12% and 15%, by mass of the SbS) were tested. OSSB was evaluated according to European standards for wood-based composites; also, a physical and chemical characterization of the SbS was performed. SbS has an irregular shape, which reduced the OSSB mechanical performance due to the low densification of the composite and the development of transversal cracks on the SbS after the OSSB manufacturing process. The static bending and thickness swelling performance of SbS OSSB was not improved by the increase of polyurethane adhesive content. SbS low ash content and neutral pH extractives indicates that probably its chemical properties should not affect the setting of the adhesive.

title: The potential of automated rule-based verification for fire safety measures in BIM

description: Abstract The aim of this study is the operationalisation of Eastman et al.’s (2009) code checking method applied to the modelling and automated verification of fire regulations for multifamily residential units in the state of São Paulo, using specific BIM tools. The method adopted was constructive research. The solution evaluation process applied the methodology in the verification of a five-stories H-shaped residential building in a social housing project built by the Housing and Urban Development Company of the state of São Paulo. The resulting devices are as follows: (i) a set of rules for fire safety code-checking for buildings with an area of over 750 m 2 and a height of 6 m to 12 m, which can be replicated to 90.8% of the remaining heights; (ii) a hierarchy to guide the coordination of the application of the various modules and rules on the object of study; (iii) a description of the required preparation of the BIM model; and (vi) clarification of the subset of model objects and properties needed for the automated verification process, which provides indications of a specific Model View Definition (MVD) for this code checking. The solution developed will make it possible to maximise the application of laws and regulations related to fire safety measures in buildings.
