Building inspection on site, in other words in-situ examinations of buildings is a troublesome work that necessitates the use of non-destructive investigation (NDT) techniques. One of the main concerns of non-destructive testing studies is to improve in-situ use of NDT techniques for diagnostic and monitoring studies. The quantitative infrared thermography (QIRT) and ultrasonic pulse velocity (UPV) measurements have distinct importance in that regard. The joint use of QIRT and ultrasonic testing allows in-situ evaluation and monitoring of historical structures and contemporary ones in relation to moisture, thermal, materials and structural failures while the buildings themselves remain intact. For instances, those methods are useful for detection of visible and invisible cracks, thermal bridges and damp zones in building materials, components and functional systems as well as for soundness assessment of materials and thermal performance assessment of building components. In addition, those methods are promising for moisture content analyses in materials and monitoring the success of conservation treatments or interventions in structures. The in-situ NDT studies for diagnostic purposes should start with the mapping of decay forms and scanning of building surfaces with infrared images. Quantitative analyses are shaped for data acquisition on site and at laboratory from representative sound and problem areas in structures or laboratory samples. Laboratory analyses are needed to support in-situ examinations and to establish the reference data for better interpretation of in situ data. Advances in laboratory tests using IRT and ultrasonic testing are guiding for in-situ materials investigations based on measurable parameters. The knowledge and experience on QIRT and ultrasonic testing are promising for the innovative studies on today’s materials technologies, building science and conservation/maintenance practices. Such studies demand a multi-disciplinary approach that leads to bring together knowledge on materials science and building science.

“…A conjugação da análise qualitativa com a termografia passiva tem-se assumido como bastante eficiente na identificação de defeitos em fachadas de edifícios revestidos a azulejos devido à infiltração de água e ar, no controlo e avaliação de sistemas de drenagem de água em edifícios históricos, na análise da performance térmica, na avaliação do desempenho da envolvente de edifícios através da análise exterior e na deteção de infiltrações e perdas de ar (Grinzato, Bison, & Marinetti, 2002;Suonketo, Korpi, & Aaltonen, 2009;Tavukcuoglu, Duzgunes, Demirci, & Caner-Saltik, 2007). Adicionando outras técnicas não destrutivas, torna-se possível alcançar resultados com significativo sucesso na avaliação do nível de isolamento térmico de edifícios históricos (Binda & Saisi, 2009;Haralambopoulos & Paparsenos, 1998).…”

A termografia, sendo uma técnica não destrutiva que permite visualizar a radiação infravermelha através de imagens térmicas visíveis e facilita a sua realização a grandes distâncias das superfícies em análise, pode considerar-se bastante vantajosa nas questões da sustentabilidade na reabilitação urbana. Esta técnica permite, com base nos resultados obtidos, o desenvolvimento de soluções mais eficientes, como revestimentos mais duradouros e/ou com maior capacidade de isolamento, permitindo a identificação de patologias que dificilmente podem ser detetadas através de outros métodos, facto que possibilita uma manutenção atempada, sem que a patologia do material se agrave. As medições dependem de diferentes parâmetros que podem influenciar os resultados, como a emissividade, a distância da câmara à superfície, o ângulo de observação, refletividade e cor. Neste caso, para as fachadas de edifícios, além dos parâmetros referidos, predominam as condições ambientais, a radiação solar e o vento. O desenvolvimento deste estudo preliminar destaca-se fundamentalmente pela prática, desde a recolha, à interpretação até à justificação dos dados térmicos registados em diversos edifícios. Independentemente das diferentes condições presentes em dias diferentes, foi possível identificar os materiais constituintes e registar os diferentes padrões de temperatura, como a transição térmica entre os mesmos materiais ao longo das horas, orientação, exposição e cores diferentes, e ainda a passagem de massas de ar quente e frio do interior dos edifícios para o exterior. Este trabalho apresenta-se relevante para uma base de estudo de implementação de medidas para maior eficiência urbana no planeamento e ordenamento do território e consequentemente, alcançar maior sustentabilidade urbana.

“…This technique is contactless and non-destructive and allows thermal images (thermograms) to be generated. It has already been widely used in the study of the energy efficiency of buildings [9][10][11][12][13][14][15][16], the pathology of building materials [17], as a tool for building diagnosis and definition of construction details [18][19][20][21][22][23][24][25], to detect moisture in building components [26][27][28][29][30][31][32][33], as a conservation evaluation tool for historic buildings [34][35][36][37][38] and to assess thermal comfort [39].…”

The EU is strongly committed to energy saving in buildings. Air leaks through the building envelope represent a significant percentage of buildings energy consumption. Locating and minimizing air leaks is thus necessary to optimize energy efficiency. This work presents the results of an experimental campaign that aimed to promote a discussion concerning the opportunities and constraints of using active IRT to detect air leakage points. The potential of active IRT was evaluated both in a qualitative approach, by comparing the thermograms with the ones obtained with passive IRT, and in a quantitative one, by testing methods of numerically interpret the thermograms. The results allowed concluding that active IRT increases the thermal contrast and the affected area, proving that active IRT combined with pressure differences is an effective methodology for detecting air infiltrations. In the quantitative approach different numerical methods can be used. Their selection depends on the aims of the study, as they can highlight different perspectives of the phenomenon.
