This image shows most heat around the door frame which was to be expected as the doors are least insulated. The walls show a significant difference to the doors and windows as they are better insulated and therefore have better efficiency and do not lose heat as easily

This image shows some significant heat loss around the lower windows

The error bars overlap in this graph implying that age of buildings and thermal gradient are not significant meaning that the age of the buildings don't necessarily impact the thermal efficiency of the building.

The graph of soil temperatures over the 2m from the building shows decreases in temperature, which was expected as the temperature outside was lower. Older buildings such as Norfolk and Suffolk have highest temperatures at 0m, showing that they lose more heat to the surroundings than the newer 2000's buildings, which started at lower temperatures at 0m and had a lower change in temperature. An exception to this is Victory House (built in 2000's) which still had a lower temperature than the 1960s but still lost a significant amount of heat to the surroundings. The newer buildings had a relatively low gradient which means that less heat is lost to the surroundings, which links to the hypothesis that newer buildings will be more thermally efficient. The graph of air temperatures over the 2m is fairly similar to the soil temperatures and both show that the older buildings have higher temperatures at 0m, implying there is greater heat loss from the buildings and they are therefore less thermally efficient. However there is greater variation in the air temperatures in the 1990s and 2000s buildings as Nelson, Norfolk and Victory house all have lower initial air temperatures then initial soil temperatures. Collectively, the two graphs support the hypothesis as they show a general trend of older buildings being less thermally efficient than the newer buildings.

The UEA accommodation have varying ages from the 1960's to 2000's, it is hypothesised that the aging of these buildings leads to significant heat loss for many reasons linking to the age it was built. Figure 1 above shows the locations on the UEA campus in which data was collected. We hypothesize that newer accommodation buildings are more thermally efficient than the older buildings.

A transect is laid out in a southerly direction from the most south facing buildings (not all buildings faced directly south so a compass on a phone was used to keep the direction constant and have it kept as a control variable). The soil and air temperature are then taken at increments of 0.5m for 2m and a control measurement (background temperature) was taken far away from any buildings so as not to be influenced by heat loss from the buildings. This procedure was then repeated 2 times for each building we were testing.
