Points to note when viewing images.

- These are reduced size image files. Full resolution images included on cd in the post to WC
- Each image has been optimised to show the greatest colour contrast within that image. Therefore colours are not directly comparable between images. Refer to temperature bar in the centre of each image
- Images recorded during quick walk around the school, and therefore are only examples of what can be done

Room 3/2 ? - metal frames and windows coldest

Thermal bridging (transfer of heat through solid object exposed to both inside and outside) around structural post


End wall (above headmasters office), showing cold - possibly damp?


Room 3/1 ? - coldest at area of unimproved wall


Faulty radiator (note uneven heating pattern on right hand radiator)


Same image,this time adjusted to show the relative cold of wall - even when situated between radiators


Heat transferring through wall from class 3/6?


Cold bridging again, and probably cold air ingress


Seal at the top of this window particulary bad


Cold air falling through hole in ceiling cooling walls. Possibly also damp


Cold ceilings at wall to ceiling join in art department rooms - likely cold air





Exposed outer wall


Roof - the blackness at the top of the flues is the reflection of the cold night sky











Interesting image
Temperature difference areas 1 to 2 is approx 6 degrees - i.e. the main glazing is losing 6 degrees more than wall average
Area 3 is the chipboard in the English department which is acting as a more effective insulator than the single glazing elsewhere!
Area 4 is one of only two brick areas on this whole wall which is at a different temperature, being approx 0.5 degrees warmer than the wall average. Perhaps positioning of radiator, or weakness in wall construction at this point?


Heat loss through this end wall - radiator positioning? Plus thermal bridging at floor plate. Ignore white area on right hand side, this is sheltered effect against lift shaft wall




Two areas marked where heat loss is greater than elsewhere. Otherwise, this wall very even. Single glazing big contributor to heat loss


Some wall heat loss as marked by arrow







Images highlight the poor insulating properties of this wall
