29、gs is paramount to improving our environment. Infrared building thermography provides a tool to quantitatively and qualitatively identify the presence of energy-wasting defects and anomalies within building structures. These defects and anomalies can include, for example, thermal insulation defects,
30、 moisture content, and / or unwanted air movement or leakage within the building envelope.Building thermography is carried out by means of an infrared radiation sensing system, which produces an image based on the apparent radiance temperature of the target surface area. The thermal radiation (infra
31、red radiation density) from the target area is converted by the infrared radiation sensing system to produce a thermal image (thermogram). This image (thermogram) represents the relative intensity of thermal radiation from different parts of the surface. The radiation intensity indicated by the imag
32、e is directly related to (i) the surface temperature and distribution, (ii) the characteristics of the surface, (iii) the ambient conditions, and (iv) the sensor itself. Also included in the thermographic process is valid interpretation of the thermal images.As a result, surface temperature distribu
33、tion can be a key parameter for monitoring the performance of building components, building envelopes and the diagnostics of problems. In use, via analysis of surface temperature distributions, irregularities in the heat and moisture properties of building envelopes and components, and air movement
34、within the building envelope, can be indicated. These irregularities can be due to, for example, thermal insulation defects, moisture content, air leakage within components, or incorrect installation of components which comprise the construction of the building.To realize its full utility as an init
35、ial qualitative screening technique, or in-depth diagnostic technique, thermography is often supported and / or validated by other methods. Such methods include, but are not limited to, infrared photosensitive tracer gas methods, fan pressurization of the building envelope, heat-flow meters, smoke d
36、iffusion, anemometry, etc.The effectiveness of the investigations depends on the competence of individuals who perform the measurements and analyse the data. A person or entity wishing to use or implement infrared thermographic services for buildings can refer to this part of ISO 6781 to understand
37、and specify (i) the competence required of operators of the thermographic equipment, and (ii) the qualifications required of interpreters of data gathered from the thermographic surveys.This part of ISO 6781 sets out the requirements and levels of competence that equipment operators, data analysts a
38、nd report writers shall possess in order to undertake thermographic investigations and the analysis and reporting of thermographic results stemming from investigations.For validity of requirements to this part of ISO 6781, assessment of competence will be undertaken by bodies qualified to train and
39、assess the competence of personnel whose duties require the appropriate theoretical and practical knowledge applicable to thermography of buildings.
