Image showing heat flux in the ground. Approximately 50% of the ground that should be included in the model is displayed in this image. Typically the ground will be modelled to a 20m depth for accurate results. Simulated in AnTherm.

Photo: OPTION 1 - MODEL A
Highly insulated wall and floor with insulated services cavity. The thermal analysis indicated that the linear heat loss through the corner would not meet building regulations. There is also a risk of condensation at the skirting area. If moisture was present in the wall there would be severe risk of interstitial condensation, the dew point is very close to the internal face of the wall. This is a detail often recommended by external insulation companies in Ireland.

The insulated service cavity is removed to move the dew point towards the external face of the wall. External insulation is continued below ground level to solve the problem of thermal bridging at the corner. The thermal bridge is still present and the detail performs worse than the previous setup. This is because the thermal envelope has a larger break due to the removal of the service cavity
