	There is a clear benefit to using non-destructive infrared thermography in traditional buildings. For example, intrusive investigations – drilling holes or dismantling construction elements – would otherwise be required to identify missing insulation and the location of thermal bridges. Furthermore, it can be difficult to identify the location of air leakage using air-pressurisation tests alone. And moisture and damp often goes unnoticed until it appears on the surface.		There is a clear benefit to using non-destructive infrared thermography in traditional buildings. For example, intrusive investigations – drilling holes or dismantling construction elements – would otherwise be required to identify missing insulation and the location of thermal bridges. Furthermore, it can be difficult to identify the location of air leakage using air-pressurisation tests alone. And moisture and damp often goes unnoticed until it appears on the surface.

−	Being able to achieve robust and reliable results from qualitative thermography requires professional training and certain environmental conditions at the time of the survey. Being able to use an infrared camera and accompanying software, and understanding and interpreting thermal images, also requires a suitable level of knowledge and experience about the survey process and the building being assessed. The correct survey process includes ensuring that the current environmental conditions are suitable, as this will maximise the accuracy of the data being collected. Although camera technology has improved over the years, along with the process itself, results still depend on the type of building fabric being surveyed. Knowledge and experience about building materials and construction methods are essential prerequisites for a successful survey.	+	Being able to achieve robust and reliable results from qualitative thermography requires professional training and certain environmental conditions at the time of the survey.

−	The criteria for the environmental conditions also vary, depending on whether an internal or external thermographic survey is required. The latter is more challenging. For example, external surveys require no solar radiation on the surface before and during the survey; no precipitation before and during the survey; a temperature difference between the inside and outside the building of at least 5°C, more commonly 10°; and wind speeds of no more than 10 metres per second (m/s), or preferably 6m/s are recommended. The length of time with no solar radiation and precipitation prior to undertaking a survey depend on the absorptance (the effectiveness of absorbing heat energy) of the building material.	+	The correct survey process includes ensuring that the current environmental conditions are suitable, as this will maximise the accuracy of the data being collected.

	To overcome the need to avoid solar radiation, many experts currently recommend undertaking thermographic surveys in the dark. Others suggest that a cold, overcast day is sufficient. It is also often advocated that thermographic surveys should be undertaken only in the winter, which could be a significant limitation to their use. Previous work has achieved reliable results to identify thermal bridging using thermography during the early hours of the morning during the summer. The most important consideration is taking due account of the environmental conditions during interpretation.
