Defines a qualitative method, by thermographic examination, for detecting thermal irregularities in building envelopes. Used initially to identify wide variations in the thermal properties, including air tightness, of the components constituting the external envelopes of buildings. The are two forms of thermography defined are; A) The IR camera is primarily intended for the inspection of the overall performance of new buildings or the result after a rebuilding operation. B) Simplifying testing with an IR camera is suitable when carrying out audits, eg. at the site of a rebuilding project or at production control or other routine inspections.
