There is an increasing drive towards low energy architecture and developing
buildings that work with the climate rather than in spite of it. One techn
ology in the area of low energy building design is that of utilising buildi
ng thermal mass and/or active thermal storage Systems. Essentially the mass
acts as a thermal flywheel and can both attenuate external energy flows an
d suppress internal environmental energy swings. These active thermal stora
ge systems can take differing configurations and in this paper the results
and comparisons for a few differing geometries and configurations are prese
nted. Relationships between slab surface temperature, cooling potential and
active core temperature are also presented. (C) 2001 Published by Elsevier
