−	According to the Technology Strategy Board, in the UK, the built environment accounts for 45% of total carbon emissions (27% from domestic buildings and 18% from non-domestic). Much of this is wasted, through: inefficient operation; inefficient equipment, appliances, machinery and plant; and losses through the building fabric. Findings from the ~~[http://www.usablebuildings.co.uk/Pages/UBProbePublications1.html~~ PROBE] studies (Post Occupancy Review of Buildings and their Engineering) demonstrated that actual energy consumption in buildings will usually be twice as much as predicted.	+	According to the Technology Strategy Board, in the UK, the built environment accounts for 45% of total carbon emissions (27% from domestic buildings and 18% from non-domestic).

	Losses through the building fabric might be the result of poor design, low-quality materials, poor workmanship, poor maintenance, or changes that have been made since completion. These losses can go unnoticed as the problem may be hidden within the building fabric.

	Thermographic surveys can help identify problems, using infrared cameras to reveal differences in surface temperatures. They locate areas of the building fabric that may be hotter or colder than surrounding areas, suggesting that there are specific losses in that area. The visual and immediate nature of the survey results can offer a relatively inexpensive and non-invasive way of helping clients and other stakeholders to understand the significance of problems that might otherwise be difficult to conceptualise.

	A thermographic survey might be undertaken for a single building, several buildings, a site or an organisation, and might be carried out for commercial or domestic clients. It might be undertaken as an isolated study, or as part of a wider energy audit undertaken to assess total energy use and propose measures to reduce consumption and costs. See Energy audit for more information.

−	NB Only materials with a high emissivity provide a reliable reading. This is because materials with a low emissivity have a tendency to reflect the temperature of surrounding objects. Typically, materials such as bricks and plaster have a high emissivity, while metals and glass have a low emissivity, See Thermography for traditional buildings for more information.	+	NB Only materials with a high emissivity provide a reliable reading. This is because materials with a low emissivity have a tendency to reflect the temperature of surrounding objects. Typically, materials such as bricks and plaster have a high emissivity, while metals and glass have a low emissivity. Thermographic surveys also require certain environmental conditions, for example an external survey should be carried out when there is no direct solar radiation. See Thermography for traditional buildings for more information.
