"the reasons for this are "deeply embedded in the culture, processes and practice at all levels of the house building industry."

It was totaly useless as the cast ali fitting all showed up as overheating due to their better emisitivity as they were matt silver as opposed to the pipe work that was polished. Its a start though. One way would be to spray the whole building with a matt black paint to give all surfaces a standard emisisivity.

The major white "hotspot" appears to be the felt roof over a bay window which could have picked up some heat from solar gain although I'm guessing this picture was taken either side of midday on an occluded reasonably cool day. Certainly the ground temperature seems to be in the region of 5C
In fact what is this picture supposed to be telling us?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1281&Focus=14945#Comment_14945 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1281&Focus=14945#Comment_14945 Sun, 24 Feb 2008 20:54:16 +0000 tony
I assume that the houses were heated and then the pictures taken

The one with the bay roof could also be no insulation in the roofy bit?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1281&Focus=14953#Comment_14953 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1281&Focus=14953#Comment_14953 Sun, 24 Feb 2008 23:10:51 +0000 Saint https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1281&Focus=14954#Comment_14954 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1281&Focus=14954#Comment_14954 Sun, 24 Feb 2008 23:16:01 +0000 tony https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1281&Focus=14957#Comment_14957 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1281&Focus=14957#Comment_14957 Mon, 25 Feb 2008 07:07:08 +0000 Mike George
That said here's my thoughts. All total conjecture of course

The red area at the front of the building is adjacent to several windows. While the cills are clearly the greatest thermal bridge, there is probably some bridging where the cavity is closed at reveals, although DPC with insulation stuck to it may have been used. Anyway, anyone who has ever laid a brick will tell you that it is these areas of the construction which are most difficult to insulate properly, especially with partial -fill. Also high potential for increased infiltration losses in these areas.

Re insulation at ceiling level- do we even know if there is a flat ceiling? The height of the windows in relation to the eaves indicates that ceilings are at least partially vaulted]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1281&Focus=14958#Comment_14958 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1281&Focus=14958#Comment_14958 Mon, 25 Feb 2008 08:49:35 +0000 DoctorJez http://www.leedsmet.ac.uk/as/cebe/projects/stamford/pdfs/del7coheating.pdf
This report discusses the results of a series of coheating tests that investigated heat losses via uninsulated party walls.. The thermal images were indeed taken during on overcast and cold day - with high delta-T due to the elevated internal temperatures.
The executive summary of the final report (draft) is also available from the Stamford Brook project web page at
http://www.leedsmet.ac.uk/as/cebe/projects/stamford/pdfs/del8execsum.pdf
The interetation of thermal images is very difficult and can be influenced by a range of factors some of which are mentioned in the comments above.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1281&Focus=14964#Comment_14964 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=1281&Focus=14964#Comment_14964 Mon, 25 Feb 2008 10:42:45 +0000 Mike George
