“…Besides diagnosis, infrared thermography can also be applied in the evaluation of building materials (Barreira and Freitas, 2007). Therefore, a priori it is an ideal non-destructive testing tool for the survey of both ancient and modern architectural cultural heritage.…”

The study carried out at the castle of Monzón (Huesca) while developing the Master Plan for the preservation of the site clearly aims at efficient interaction between different studies by several groups of experts in various disciplines. The various studies were coordinated jointly in order to offer a comprehensive analysis of the monument, intertwining approaches and points of views. Among the techniques used, thermography was especially interesting because of its flexibility and adaptability in several applications: from helping to identify materials to the detection of hidden pathologies. The efficiency of thermography for emphasizing different phenomena can only be improved by combining with other survey and analysis techniques. Synoptic plans allow these techniques to enrich the information available, reaching greater accuracy in determining materials and pathologies.

“…The quantitative use of thermal imaging requires knowledge of the emissivity of the material constituting the target in the spectral range of the infrared camera used to perform the image acquisition (Avdelidis and Moropoulou 2003;Barreira and de Freitas 2007). This physical quantity characterises the ability of a material to emit thermal radiation at particular wavelengths.…”

The anisotropic temperature rise on wood surfaces during adsorption measured by thermal imaging

The aim of the work reported herein was to investigate anisotropy in the temperature rise occurring on the surface of Scots pine (Pinus sylvestris L.) during adsorption. The temperature increase on the transverse, radial and tangential surfaces of small wood specimens during adsorption was measured by thermal imaging. The experiments were conducted in a purpose-built humidity chamber facilitating the accurate control of the internal relative humidity (RH). It was found that the temperature rise on initially oven-dry wood surfaces exposed to a RH of 95% was anisotropic, with a maximum temperature increase of around 4 °C occurring on the transverse surface and around 1 °C on both the radial and tangential surfaces. Additionally, it was observed that the technique reported can be used to accurately measure the temperature change arising from sorption, thus providing reliable information about the behaviour of wood. This information is vital if the effects of the enthalpy change occurring during water vapour sorption are to be correctly considered in building physics models and the potential to reduce energy consumption in buildings fully realised.

“…Obviously, temperatures are a result of the action of various factors, including the action of climatic agents such as the incidence of the sun and ambient temperature. Elements in thermal or hygroscopic equilibrium with the environment are difficult to study in thermography since significant differences in surface temperature become more difficult to identify [2]. There must be a heat flux from the external environment to the facade (direct) or from the facade to the environment (inverse) to identify the anomalies.…”

Facades inspection with infrared thermography: cracks evaluation

et al. 2016

View full text Add to dashboard Cite

Infrared thermography is an evaluation technique that helps to identify anomalies and can provide information on their incidence and severity. The aim of this study is to apply quantitative thermography to study a case of severe cracks in facade analyzing the evolution of temperatures and Delta-T. The temperature evolution was studied over a day. There was sun incidence occurring during part of the day, allowing to calculate and assess the evolution of the associated temperatures. Thermograms were acquired hourly during the study period. The highest temperatures were observed at 12:00 noon, and the larger Delta-T between 10:00 and 12:00. There were differences between the Delta-T profiles among the three regions studied. The best time for analysis is when Delta-T is higher. Cracks with higher Delta-T were considered more degraded, and generalized branched cracks did not allow a comparative conclusion.
