Analysis ‣ Given small sample size: • For the walls plastered on the hard there is some correlation between wall thickness and U-valueU • The walls with lath and plasterboard finishes have lower U-U values than those plastered on the hard • It is not possible to distinguish between the different masonry types 28
Analysis ‣ In the case <strong>of</strong> the Crichton Campus building (Locharbriggs sandstone), the six measurements show a greater range than those made in the other buildings with lath and plaster finishes. ‣ However, the ventilated walls in the Crichton Campus building have some influence on the U-value U estimates, particularly on the top floor <strong>of</strong> the building. 29
