Abstract

Architectural heritage, building materials and interior space are highly susceptible to temperature and relative humidity. A better knowledge of the hygrothermal dynamics inside buildings allows an adequate conservation of heritage. This work compares three non-destructive techniques (NDT), such as temperature and relative humidity sensors, finite element simulations (CFD) and thermographic pictures (IRT). The work has made it possible to carry out an assessment of the risk of condensation over a year and to identify affected periods and areas of the building. Sensors and IRT pictures provide real data to validate CFD simulations, facilitating a global analysis of the building. The results provided reflect a great concordance between the NDTs used.

摘要

建筑遗产、建筑材料和室内空间极易受到温度和相对湿度的影响。更好地了解建筑物内部的湿热动态有助于对遗产进行充分保护。这项工作比较了三种无损检测技术（NDT），即温度和相对湿度传感器、有限元模拟（CFD）和热成像图片（IRT）。该工作使得能够对一年内的冷凝风险进行评估，并识别建筑物受影响的时期和区域。传感器和IRT图片提供真实数据以验证CFD模拟，便于对建筑物进行全面分析。所提供的结果反映了所使用的无损检测技术之间具有高度一致性。
