33、SO 6781-3:2016-05 EN ISO 6781-3:2015 (E)4 IntroductionReducing energy use in buildings 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 structure
34、s. These defects and anomalies can include, for example, thermal insulation defects, 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 ap
35、parent radiance temperature of the target surface area. The thermal radiation (infrared 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 radiatio
36、n from different parts of the surface. The radiation intensity indicated by the image 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
37、valid interpretation of the thermal images.As a result, surface temperature distribution 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
38、heat and moisture properties of building envelopes and components, and air movement 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 wh
39、ich comprise the construction of the building.To realize its full utility as an initial 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
40、 gas methods, fan pressurization of the building envelope, heat-flow meters, smoke diffusion, 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 th
41、ermographic services for buildings can refer to this part of ISO 6781 to understand 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
42、 the requirements and levels of competence that equipment operators, data analysts and 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
43、 6781, assessment of competence will be undertaken by bodies qualified to train and assess the competence of personnel whose duties require the appropriate theoretical and practical knowledge applicable to thermography of buildings.DIN EN ISO 6781-3:2016-05 EN ISO 6781-3:2015 (E)5 1 ScopeThis part o
44、f ISO 6781 specifies the qualifications and competence requirements for personnel who (i) perform thermographic investigations on buildings, (ii) interpret the data emanating from thermographic investigations, and (iii) report the results of thermographic investigations.This part of ISO 6781 provide
45、s the basis for a statement of conformity, in three classes, of the knowledge, skills and abilities of individuals to perform thermographic measurements, analysis and reporting of results for small buildings, residential buildings, and commercial and institutional buildings.This part of ISO 6781 is
