Impact of insulation configuration on the ability of a basement thermal mass to shape heat losses

Michaël Fournier, François Laurencelle

Abstract: This paper presents a comparative analysis of the impact of several basement insulation configurations on indicators of the effects of a thermal mass over the heat losses through the foundations. The first set of two-dimensional dynamic simulations shows that a split configuration insulation enables to marginally increase the delay of the heat losses. To further shift the losses, the heat storage capacity is gradually increased by thermally linking a portion of the surrounding ground to the basement wall. The shift increases effectively but probably not to the point of justifying the more elaborate assembly. One of the intermediate configuration could however be used as a retrofit option to reduce winter heat losses.
