Typical field investigations 7.2.1 Guidelines As will be noted in subsequent sections there are a number of general guidelines the user should take heed of when carrying out building thermography inspection.
7 – Introduction to building thermography 7.2.1.2 Guidelines for moisture detection, mold detection & detection of water damages Building defects related to moisture and water damages may only show up when ■ heat has been applied to the surface, e.g. from the sun. The presence of water changes the thermal conductivity and the thermal mass of ■...
7 – Introduction to building thermography A difference in temperature between the inside and the outside of 10–15°C (18–27°F) ■ is recommended. Inspections can be carried out at a lower temperature difference, but will make the analysis of the infrared images somewhat more difficult. Avoid direct sunlight on a part of a building structure—e.g.
7 – Introduction to building thermography Although a basic understanding of the construction of low-slope commercial roofs is desirable when carrying out a roof thermography inspection, expert knowledge is not necessary. There is a large number of different design principles for low-slope com- mercial roofs—both when it comes to material and design—and it would be impossible for the infrared inspection person to know them all.
7 – Introduction to building thermography 7.2.3.3 Commented building structures This section includes a few typical examples of moisture problems on low-slope commercial roofs. Structural drawing Comment 10553603;a2 Inadequate sealing of roof membrane around conduit and ventilation ducts leading to local leakage around the conduit or duct.

7 – Introduction to building thermography 7.2.4 Moisture detection (2): Commercial & residential façades 7.2.4.1 General information Thermography has proven to be invaluable in the assessment of moisture infiltration into commercial and residential façades. Being able to provide a physical illustration of the moisture migration paths is more conclusive than extrapolating moisture meter probe locations and more cost-effective than large intrusive test cuts.
Page 39
7 – Introduction to building thermography Structural drawing Comment 10554503;a2 Rain hits the façade at an angle and penetrates the plaster through cracks. The water then follows the inside of the plaster and leads to frost erosion. 10554603;a2 Rain splashes on the façade and penetrates the plaster and masonry by absorption, which eventu- ally leads to frost erosion.
7 – Introduction to building thermography 7.2.4.3 Commented infrared images This section includes a few typical infrared images of moisture problems on commercial & residential façades. Infrared image Comment 10554703;a1 Improperly terminated and sealed stone veneer to window frame and missing flashings has resulted in moisture infiltration into the wall cavity and inte- rior living space.
7 – Introduction to building thermography 7.2.5.2 Commented building structures This section includes a few typical examples of moisture problems on decks and balconies. Structural drawing Comment 10555203;a2 Improper sealing of paving and membrane to roof outlet, leading to leakage during rain. 10555103;a2 No flashing at deck-to-wall connection, leading to rain penetrating the concrete and insulation.
Page 42
7 – Introduction to building thermography Structural drawing Comment 10555003;a2 Water has penetrated the concrete due to inade- quately sized drop apron and has led to concrete disintegration and corrosion of reinforcement. SECURITY RISK! 10554903;a2 Water has penetrated the plaster and underlying masonry at the point where the handrail is fastened to the wall.
7 – Introduction to building thermography 7.2.5.3 Commented infrared images This section includes a few typical infrared images of moisture problems on decks and balconies. Infrared image Comment 10555303;a1 Improper flashing at balcony-to-wall connections and missing perimeter drainage system resulted in moisture intrusion into the wood framing support structure of the exterior walkway balcony of a loft complex.
7 – Introduction to building thermography 7.2.6.2 Commented infrared images This section includes a few typical infrared images of plumbing breaks & leaks. Infrared image Comment 10555503;a1 Moisture migration tracking along steel joist chan- nels inside ceiling of a single family home where a plumbing line had ruptured.

7 – Introduction to building thermography Infrared image Comment 10555703;a1 The infrared image of this vinyl-sided 3-floor apartment house clearly shows the path of a seri- ous leak from a washing machine on the third floor, which is completely hidden within the wall. 10555803;a1 Water leak due to improper sealing between floor drain and tiles.
7 – Introduction to building thermography 7.2.7 Air infiltration 7.2.7.1 General information Due to the wind pressure on a building, temperature differences between the inside and the outside of the building, and the fact that most buildings use exhaust air terminal devices to extract used air from the building, a negative pressure of 2–5 Pa can be expected.
Page 47
7 – Introduction to building thermography Structural drawing Comment 10552303;a2 Insulation deficiencies in an intermediate floow due to improperly installed fiberglass insulation batts. The air infiltration enters the room from behind the cornice. 10552603;a2 Air infiltration in a concrete floor-over-crawl-space due to cracks in the brick wall façade.
7 – Introduction to building thermography 7.2.7.3 Commented infrared images This section includes a few typical infrared images of details of building structures where air infiltration has occurred. Infrared image Comment 10552703;a1 Air infiltration from behind a skirting strip. Note the typical ray pattern.
7 – Introduction to building thermography 7.2.8 Insulation deficiencies 7.2.8.1 General information Insulation deficiencies do not necessarily lead to air infiltration. If fiberglass insulation batts are improperly installed air pockets will form in the building structure. Since these air pockets have a different thermal conductivity than areas where the insulation batts are properly installed, the air pockets can be detected during a building ther- mography inspection.
Page 50
7 – Introduction to building thermography Structural drawing Comment 10553103;a2 Insulation deficiencies due to improper installation of insulation batts around an attic floor beam. Cool air infiltrates the structure and cools down the in- side of the ceiling. This kind of insulation deficiency will show up as dark areas on an infrared image.
7 – Introduction to building thermography 7.2.8.3 Commented infrared images This section includes a few typical infrared images of insulation deficiencies. Infrared image Comment 10553303;a1 Insulation deficiencies in an intermediate floor structure. The deficiency may be due to either missing insulation batts or improperly installed in- sulations batts (air pockets).

7 – Introduction to building thermography Theory of building science 7.3.1 General information The demand for energy-efficient constructions has increased significantly in recent times. Developments in the field of energy, together with the demand for pleasant indoor environments, have resulted in ever-greater significance having to be attached to both the function of a building’s thermal insulation and airtightness and the efficiency of its heating and ventilation systems.
7 – Introduction to building thermography the results of measurements, there are special requirements in terms of the skills and experience of those taking the measurements, e.g. by means of authorization by a national or regional standardization body. 7.3.2 The effects of testing and checking It can be difficult to anticipate how well the thermal insulation and airtightness of a completed building will work.
7 – Introduction to building thermography For the user the important thing is that the finished product fulfills the promised ■ requirements in terms of the building’s thermal insulation and airtightness. For the individual, buying a house involves a considerable financial commitment, and the purchaser therefore wants to know that any defects in the construction will not in- volve serious financial consequences or hygiene problems.
Page 56
7 – Introduction to building thermography The temperature changes associated with variations in the U value are generally gradual and symmetrically distributed across the surface. Variations of this kind do of course occur at the angles formed by roofs and floors and at the corners of walls. Temperature changes associated with air leaks or insulation defects are in most cases more evident with characteristically shaped sharp contours.
7 – Introduction to building thermography Any wet surfaces, e.g. as a result of surface condensation, have a definite effect on heat transfer at the surface and the surface temperature. Where there is moisture on a surface, there is usually some evaporation which draws off heat, thus lowering the temperature of the surface by several degrees.
Page 58
7 – Introduction to building thermography In a steady wind flow, Bernoulli’s Law applies: where: ρ Air density in kg/m Wind velocity in m/s Static pressure in Pa and where: denotes the dynamic pressure and p the static pressure. The total of these pressures gives the total pressure.

The position of the neutral zone may vary, depending on any leaks in the building.
7 – Introduction to building thermography 7.3.5 Measuring conditions & measuring season The foregoing may be summarized as follows as to the requirements with regard to measuring conditions when carrying out thermographic imaging of buildings. Thermographic imaging is done in such a way that the disruptive influence from ex- ternal climatic factors is as slight as possible.
Page 64
7 – Introduction to building thermography In practice the method involves the following: Laboratory or field tests are used to produce an expected temperature distribution in the form of typical or comparative infrared images for common wall structures, com- prising both defect-free structures and structures with in-built defects. Examples of typical infrared images are shown in section 7.2 –...
7 – Introduction to building thermography Deviations and irregularities in the appearance of the infrared image often indicate insulation defects. There may obviously be considerable variations in the appearance of infrared images of structures with insulation defects. Certain types of insulation defects have a characteristic shape on the infrared image.

Thermographic measurement techniques 16.1 Introduction An infrared camera measures and images the emitted infrared radiation from an object. The fact that radiation is a function of object surface temperature makes it possible for the camera to calculate and display this temperature. However, the radiation measured by the camera does not only depend on the tem- perature of the object but is also a function of the emissivity.

History of infrared technology Less than 200 years ago the existence of the infrared portion of the electromagnetic spectrum wasn’t even suspected. The original significance of the infrared spectrum, or simply ‘the infrared’ as it is often called, as a form of heat radiation is perhaps less obvious today than it was at the time of its discovery by Herschel in 1800.

17 – History of infrared technology however, who was the first to recognize that there must be a point where the heating effect reaches a maximum, and that measurements confined to the visible portion of the spectrum failed to locate this point. 10398903;a1 Figure 17.2 Marsilio Landriani (1746–1815) Moving the thermometer into the dark region beyond the red end of the spectrum,...

Page 146
17 – History of infrared technology The improvement of infrared-detector sensitivity progressed slowly. Another major breakthrough, made by Langley in 1880, was the invention of the bolometer. This consisted of a thin blackened strip of platinum connected in one arm of a Wheatstone bridge circuit upon which the infrared radiation was focused and to which a sensitive galvanometer responded.
Theory of thermography 18.1 Introduction The subjects of infrared radiation and the related technique of thermography are still new to many who will use an infrared camera. In this section the theory behind ther- mography will be given. 18.2 The electromagnetic spectrum The electromagnetic spectrum is divided arbitrarily into a number of wavelength re- gions, called bands, distinguished by the methods used to produce and detect the radiation.
Such cavity radiators are commonly used as sources of radiation in temperature reference standards in the laboratory for calibrating thermo- graphic instruments, such as a FLIR Systems camera for example. Publ. No. 1558440 Rev. a156 – ENGLISH (EN) – February 28, 2006...
18 – Theory of thermography If the temperature of blackbody radiation increases to more than 525 °C (977 °F), the source begins to be visible so that it appears to the eye no longer black. This is the incipient red heat temperature of the radiator, which then becomes orange or yellow as the temperature increases further.
18 – Theory of thermography Planck’s formula, when plotted graphically for various temperatures, produces a family of curves. Following any particular Planck curve, the spectral emittance is zero at λ = 0, then increases rapidly to a maximum at a wavelength λ and after passing it approaches zero again at very long wavelengths.
Page 151
18 – Theory of thermography 10399403;a1 Figure 18.5 Wilhelm Wien (1864–1928) The sun (approx. 6 000 K) emits yellow light, peaking at about 0.5 μm in the middle of the visible light spectrum. At room temperature (300 K) the peak of radiant emittance lies at 9.7 μm, in the far infrared, while at the temperature of liquid nitrogen (77 K) the maximum of the almost insignificant amount of radiant emittance occurs at 38 μm, in the extreme infrared wavelengths.
18 – Theory of thermography 18.3.3 Stefan-Boltzmann's law By integrating Planck’s formula from λ = 0 to λ = ∞, we obtain the total radiant emittance (W ) of a blackbody: This is the Stefan-Boltzmann formula (after Josef Stefan, 1835–1893, and Ludwig Boltzmann, 1844–1906), which states that the total emissive power of a blackbody is proportional to the fourth power of its absolute temperature.
Page 153
18 – Theory of thermography There are three processes which can occur that prevent a real object from acting like a blackbody: a fraction of the incident radiation α may be absorbed, a fraction ρ may be reflected, and a fraction τ may be transmitted. Since all of these factors are more or less wavelength dependent, the subscript λ...

18 – Theory of thermography For highly polished materials ε approaches zero, so that for a perfectly reflecting λ material (i.e. a perfect mirror) we have: For a graybody radiator, the Stefan-Boltzmann formula becomes: This states that the total emissive power of a graybody is the same as a blackbody at the same temperature reduced in proportion to the value of ε...
