title: Multiple linear regression model to evaluate the market value of residential apartments in Fortaleza, CE

description: Abstract The valuation of real estate, which assists in the definition of market value, is an important science with a wide field of action, which includes the collection of taxes, commercial transactions, insurance and judicial expertise. This study presents the construction of a linear regression model to determine the market value (dependent variable) of residential apartments in the city of Fortaleza-CE. The studied database presents 17,493 apartments, divided into 227 plan types in a total of 154 projects launched between the years of 2011 and 2014. The model developed was obtained using Multiple Linear Regression associated with the Ridge Regression technique to solve the existing multicollinearity problem. In the analysis of 30 variables (12 quantitative and 18 dummy type qualitative variables), an equation with 6 variables was reached, which meets the theoretical assumptions for its existence.

title: Influence of the installation conditions of stormwater drainage building systems on source drainage solutions

description: Abstract Source drainage systems are gaining importance as low-impact development solutions deployed in built-up areas. However, only limited number of research studies have evaluated the influence of the installation conditions of stormwater drainage building systems on these systems' performance. This paper evaluates the influence of the adoption of different components of installation of stormwater drainage systems on the performance of infiltration systems. With that purpose, two experimental systems were executed: a dry-well and a rain garden, containing vertical and horizontal conductors mounted according to installations that represent a vertical building. The study evaluated the flow in the conductor branch that directs the stormwater to the infiltration system and the occurrence of water return to catchment points positioned near the infiltration systems. The experiment showed that part of the drained volume of stormwater passes directly to the piping that flows into the urban drainage system in certain plumbing fittings configurations that direct the stormwater to the infiltration system, reducing the overall efficiency of the system. In addition, reflux occurred in drainage boxes positioned upstream of the infiltration systems, indicating the need for caution in the positioning of these components.

title: Use of infrared thermography for detection of moisture sources in internal walls of buildings

description: Abstract The use of infrared thermography has become the theme of studies in several areas of the construction industry. However, research studies on detecting the presence of moisture in buildings are still under development. The main objective of this article was to study the feasibility of the use of thermography in the detection of infiltrations due to accidental causes in internal walls. The methodology consisted of the construction of masonry walls made of ceramic bricks with different coating configurations: uncoated, with plaster, plaster with latex paint, plaster with acrylic base paint and plaster with ceramic set with plaster glue. In each prototype, a drilled pipe was inserted to simulate water leaks. The infiltration progress was verified by means of thermograms, for a period of 2 hours with constant flow, and at 48 hours and one week after the beginning of the simulation. The results confirm that thermography may be effective in detecting the region containing the focus of hidden infiltration, provided the coating is not impermeable. This fact can be observed in the thermal gradients produced in the porous coatings, where ΔT ranged from 2.6 to 3.8 º C, whereas coatings with waterproof characteristics had a maximum ΔT of 2.2 ºC. In addition, the type of coating directly influences the time required for the appearance of the moisture spot to become apparent.

title: A meta-analysis over geometric modeling simplifications in ENVI-met urban climate simulation

description: Abstract Environmental modelling requires, among other aspects, a description of the built geometry. However, the complexity of the urban tissue draws uncertainties about the building form and locations. Therefore, during the planning process generic simplified geometry models may be more appropriate than the detailed ones. This research shows a meta-analysis performed by comparing the results of detailed and simplified geometric models. The prediction deviations that may arise from using geometric simplifications on ENVI-met modelling were evaluated, considering the output data from different building typologies (one and ten-storey buildings) and urban scenarios (with and without internal squares). Three metrics were analysed: air temperature, wind speed, and sky view factor (SVF). These metrics were normalized between 0 and 1 for comparison and performance assessment. The results indicated that the most adequate simplification models are those that that have kept the building perimeter of the blocks unchanged in relation to the corresponding detailed models.

title: Modelling of basement heat transfer in EnergyPlus simulation program

description: Abstract Soil temperature is one of the most influential factors in the evaluation of the thermal performance of underground environments, but it is almost always disregarded. Thus, it is necessary to evaluate this influence due to the interaction of the soil with the building, since heat transfer through subterranean walls and floors has a significant extension in the total thermal load of a building. This study compares and evaluates the impact of different modelling alternatives present in the EnergyPlus simulation program by analysing the heat exchanges between the soil, the floor and the walls of a basement of a single-story building in São Paulo, Brazil, not artificially conditioned and not insulated thermally. The comparison between the modelling alternatives through the analysis recommended by NBR 15575 indicated a large variation in the internal temperature results of the underground building environment. When compared with Basement pre-processor, the models of the object GroundDomain presented an internal temperature variation of the basement up to 6 ºC in the summer and up to 5.2 ºC in the winter. These results offer indications of the influence and variability that the use of the different modelling options present in EnergyPlus program can generate in a thermal performance analysis.

title: Hypothetical study for a preliminary evaluation of resilience in urban mobility

description: Abstract The aim of this study aims is to develop a strategy to evaluate the resilience of urban mobility. The approach is based on the assumption that no forms of motorised transport would be available. Hence, only walking and cycling were considered as urban transport modes for the purpose of this theoretical exercise. The trips were initially classified in two groups, according to their adaptability or transformability. Those in the first group are considered resilient trips. However, a third category had to be created to represent another set of resilient trips. These are the exceptional trips, i.e. walking or cycling trips that are longer than the Maximum Possible Distances (MPD) defined for the evaluation of resilience. In an application of the method conducted in the city of São Carlos - SP, with MPDs of 3 km (for walking) and 8 km (for cycling), 97.7% of the trips were classified as resilient, which is a positive outcome.

title: The orientation and mobility of visual impaired people in bus and subway networks in Brazil

description: Abstract Spatial orientation depends both on the information available in the surrounding’s environment and on the individual's ability to perceive and deal with this information. To be fully understand by its users as a transport network and, to independently move from one place to another, the urban public transport service must be able to provide accessible information where users can easily discover and reach different, and to socially engage in local activities. In Brazil, the information disposable to users is scarce and sometimes nonexistent in the urban public transport (PT), especially regarding the supply of information to everyone. This paper presents some doctoral research’s results applied in Brazil and discuss blind users’ orientation and mobility in urban public transport network. The investigation involved around two hundred blind and partially impaired users from many Brazilian regions where surveys were conducted; additionally, interviews with a focus group and the "Accompanied Walks” method. The results of the latter are here presented, showing environmental barriers and users needs.

title: Sidewalk Service Index (ISC)

description: Abstract The service offered by the pedestrian circulation infrastructure must meet local demand, providing comfort and safety to its users. This issue is particularly important in small towns, where, due to the lack of public transport and the short distances, walking is the basis of urban mobility. The aim of this research study was to propose method of evaluation of the Level-of-Service (LoS) of sidewalks in small urban centers, aiming to provide a technical resource to the management of these spaces by Municipalities. The model developed and applied in São Tomé, Paraná, Brazil, was called the Sidewalks Service Index (ISC in Portuguese), consisting of two indices that involve aspects of Space Quality and Accessibility (ISCqe and ISCa in Portuguese). The method involved three steps: technical analysis of the sidewalks (570 stretches), verification of users’ perceptions by means of opinion polls (355 citizens) and assignment of Service Levels, varying from A to F (worst situation), according to results of the indices. There was a higher occurrence of LoS F, mainly in the peripheral urban areas. The most adequate Levels-of-Service (LoS A to D) were assigned to 34.91% of the stretches. The proposed model presented adequate applicability to small towns, with adaptations possible for use in larger centers.

title: Synergistic effect of RHA and FCW in alkali-aggregate reaction mitigation

description: Abstract Pozzolans rich in silica, such as Rice Husk Ash (RHA), contribute to compressive strength gain but at the same time might increase alkali-aggregate reaction (AAR) in mortar mixtures. Pozzolans that have aluminates, such as Fired Clay Brick Waste (FCW), can be efficient to mitigate AAR but tend to lead to a slower compressive strength development. The association of different types of pozzolans, however, may result in a synergistic effect, compensating individual deficiencies. This paper presents a study of mixtures containing RHA, FCW and these two materials combined, aiming to obtain benefits in the mechanical behavior and in the durability regarding AAR. A substitution rate of 20% Portland cement by pozzolanic material was used. Through accelerated AAR tests and compressive strength measurements, it was found that while RHA is considered harmful to AAR - even when using an innocuous aggregate - FCW presents benefits, also avoiding this deleterious effect when combined with RHA. The same occurs in the compressive strength development, where RHA compensates a small loss of compressive strength associated with the use of FWC alone.

title: Use of electric arc furnace slag for producing concrete paving blocks

description: Abstract In this study the electric arc furnace slag was used as coarse natural aggregate substitute in concrete paving blocks production. The concrete mixture was defined by using weight proportions in the ratio of 1:2:3:0.51 (cement:sand:coarse aggregate:water) in order to obtain a compressive strength of 35 MPa. Four groups of concrete were prepared: a reference recipe and three others with the slag replacing the natural aggregate in the proportions of 25%, 50% and 75%. The compressive strength was not influenced by the slag content; however, it was influenced by the curing age, as the sample with 75% of slag addition had its compressive strength increased by 13.5% from 7 to 56 days. Water absorption presented a slightly reduction with slag addition. The results of compressive strength and water absorption met the Brazilian technical requirements, making the paving blocks suitable for use in light vehicle traffic. The results obtained in this study highlight the influence of the production process in the final quality of the steel slag, and the need of stablishing technical and environmental requirements to guide and promote the safe use of electric arc furnace slag in concrete.
