typically captured using solar collectors, although other energy sources may
be used separately or in parallel. Seasonal thermal storage can be divided
into three broad system types: low temperature, warm temperature multisea-
sonal, and high temperature systems. Low temperature systems use the soil
adjoining a building as a seasonal heat store, drawing on the stored heat for
space heating. This heat store often reaches temperatures similar to the aver-
age annual air temperature [14]. Such systems can also be seen as extension
of buildings although this design involves some simple but significant dif-
ferences not found in traditional buildings. Warm temperature interseasonal
