How a heating break effects the room temperature

In all 10 houses we simulated a heating break of two days. The initial interior temperature was 21 °C, the outer temperature was -12 °C.

We recorded interesting results: after 2 days, in non-insulated house the wall temperature was 1 °C and the interior temperature was 4 °C. 

Insulated houses with massive walls kept the both – the wall and interior temperatures between 15 °C and 17 °C.

Thermal insulation saves energy costs:

The measurement between December 2015 and January 2016 showed that for keeping the pleasant 21 °C interior temperature the insulated houses (U=0,15) needed only 40% of energy in comparison to non-insulated house.

Energy matters. We save it. You save too.
