  1. 1. ThermalImaging<br />
  2. 2. A Thermal Imaging Camera makes an image from thousands of surface temperature measurements<br />The Camera detects ‘thermal’ radiation in the infrared range of the electromagnetic spectrum <br />The Camera coverts this longer wavelength ‘thermal’ radiation into visual images<br />How it Works <br />2<br />
  3. 3. Identifies the areas of air leakage/heat loss<br />Shows thermal insulation defects<br />Identifies Cold bridges<br />Condensation Identification <br />Electrical Faults<br />Leak Detection <br />Quality Control during Building<br />Post Construction Survey<br />Pre – Purchasing Survey<br />Can improve previous designs<br />Applications in Construction<br />3<br />
  4. 4. An instantaneous picture of heat loss allowing<br /> a quick assessment of defects<br />Quick inspection – Rapid Scanning of Large areas<br />Non Invasive <br />Results are easily shown visually<br />Can be used to show efficacy of heating and cooling installations<br />Improve design detailing<br />Benefits of Thermal Imaging <br />4<br />
  5. 5. Medical Science – Tumour Detection<br />Fire Fighting<br />Swine Flu/Disease Detection<br />Bruise Detection in Apples & Fruits<br />Equine Science<br />Other Uses<br />5<br />
  6. 6. Only Detects Surface Temperatures Differences<br />Does not quantify heat loss <br />Better if it has a controlled environment <br />Cannot detect sub surface problems<br />Cannot detect moisture levels, just a anomaly <br />Thermal Imaging Camera Costs <br />Limitations <br />6<br />
  7. 7. Recommend a Air Tightness Test in conjunction with a Thermal Image Survey<br />Best to carry it out in the Morning – No sunshine on façade for 4 hours <br />No Rain/Mild Wind Only<br />10 Degrees Internal/External Temperature Difference<br />Ideally have the heating on for 2 hours prior to Survey<br />Access to all Rooms<br />Domestic Survey <br />7<br />
  8. 8. Examples – Leak Detection<br />8<br />
  9. 9. Air Loss/Infiltration <br />9<br />
  10. 10. Missing Insulation<br />10<br />
  11. 11. Single Problem e.g. Leak - €200 First Hour, €75 per hour after<br />Thermal Imaging report & photographs with description of findings - €300<br />Air Tightness Test with & Thermal Image Survey & Report - €450 <br /> Figures Based on a 3 Bed Semi-Detached House in Dublin <br />How Much Does a Survey Cost?<br />11<br />
