Variability of the Hot Box Method in Assessing Thermal Resistance of a Double L...
Ribas, M; Eva Barreira; Almeida, RMSFThe accurate thermal performance assessment of building components is critical for improving energy efficiency in buildings, mainly as space climatization accounts for a large percentage of energy consumption. The literature review points out multiple parameters that influence the measurement of the U-value using the HFM method. However, most of these studies are focused on in situ tests and little information ...
Critical Review on the Energy Retrofitting Trends in Residential Buildings of A...
Almomani, A; Almeida, RMSF; Vicente, R; Eva BarreiraIn the 21st century, global energy security is a critical concern. Buildings contribute to over 40% of the worldwide energy consumption, primarily due to heating and cooling, resulting in a third of greenhouse gas emissions. The residential sector accounts for 25% of global electricity consumption, and in the Arab Mashreq and Maghreb (AMM) countries, the residential sector consumes around 41% of the total elect...
Indoor Environment in Kindergartens Located in the North of Portugal: Evaluatio...
Eva Barreira; Almeida, RMSF; Guimaraes, JAdequate school buildings are essential for the development of children, young people, and adolescents, as they must provide conditions that support their well-being and health. A healthy and comfortable indoor environment is critical for students' performance in the learning process. This study aims to evaluate the indoor environment in kindergartens located in northern Portugal, with a primary focus on therma...
Characterization of a Wall System with Dynamic Thermal Insulation-Experimental ...
Almeida, RMSF; Teles Ribeiro, M; Eva BarreiraDynamic thermal insulation systems (DTISs) can adapt to external environment conditions and help to reduce energy consumption and increase occupants' thermal comfort, contributing towards the mitigation of overheating. DTISs adjust their configuration to optimize heat transfer through the facade. In this study, the performance of a DTIS was assessed through laboratory tests and numerical simulation. The DTIS is...
Machine learning models applied to moisture assessment in building materials
Dafico, LCM; Eva Barreira; Almeida, RMSF; Vicente, RMoisture-related defects hinder long-term building durability and must be prevented. Non-destructive techniques that measure the surface temperature of building materials have good potential for moisture analysis. This article presents machine learning models to predict the moisture content of materials according to their surface temperature using as input the material and the environmental conditions. Results ...
Introduction of active thermography and automatic defect segmentation in the th...
Garrido, I; Eva Barreira; Almeida, RMSF; Laguela, SInfraRed Thermography (IRT) has proven to be a valuable diagnostic tool due to its real-time, remote, and nondestructive operation yielding accurate detection of the position of defect areas in building facade ceramic tiling. Ceramic tiles coating building facades are widely used throughout the world because of their technical and aesthetic characteristics. However, the detachment of ceramic tiles and the water...
Infrared Thermography to Evaluate Thermal Comfort under Controlled Ambient Cond...
Almeida, RMSF; Eva Barreira; Maria Lurdes Simões; Sousa, TSFInfrared thermography (IRT) is often used to assess body temperature and can be useful as a diagnostic tool to detect human diseases. Despite this clear application in medicine, some studies can be found in the literature pointing to the use of IRT to measure body temperature as a parameter to evaluate thermal comfort inside buildings. However, there are still some issues that are understudied that this paper t...
Comparison of Infrared Thermography and Other Traditional Techniques to Assess ...
Dafico, LCM; Eva Barreira; Almeida, RMSF; Carasek, HHigh moisture content is a recurrent problem in masonry and can jeopardize durability. Therefore, precise and easy-to-use techniques are welcome both to evaluate the state of conservation and to help in the diagnosis of moisture-related problems. In this research, the humidification and drying process of two wall specimens were assessed by infrared thermography and the results were compared with two traditional...
Evaluation of the Effect of Passive Cooling Techniques on Thermal Comfort Using...
Marcolini, M; Almeida, RMSF; Eva BarreiraThe high consumption of electricity in Palmas, Brazil is a direct consequence of the high temperatures identified throughout the year. Therefore, it is necessary to search for sustainable technologies that contribute to comfort through passive cooling, thus reducing the energy consumption. This work presents the results of an experimental campaign of 11 months, in which the effects of shading devices, the use o...
BIM framework for the specification of information requirements in energy-relat...
Sanhudo, L; Martins, JP; Nuno Ramos; Almeida, RMSF; Rocha, A; Pinto, D; Eva Barreira; M. Lurdes SimõesPurpose This paper aims to further the discussion on Building Information Modelling (BIM) legal requirements, providing a framework with key energy parameters capable of supporting the Appointing Party in the definition of the Exchange Information Requirements (EIR) for a BIM project appointment. The EIR is described in ISO-19650-1:2018 as a fundamental step in the information delivery cycle. Design/methodology...
