Abstract: In an environment that experiences drastically changing temperatures it is potentially more energy efficient to use insulative walls that can change their apparent thermal conductivities. This paper suggests a nano-porous material able to change its thermal conductivity by a factor of 3 varying the pressure upon it from 1 to 100 kPa. Thermal conductivity measurements are made in-situ by an airtight guarded heat flow meter.
