Abstract: A system includes a wall panel with an exterior wall. An interior wall is separated from the interior wall by a variable insulation gap occupied by an insulation medium. A flow driver is connected in fluid communication with the insulation medium. The flow driver is configured to selectively switch properties of the insulation medium in the variable insulation gap between a conduction mode and in an insulation mode. The insulation medium has a first effective thermal conductivity in the insulation mode, and a second effective thermal conductivity in the conduction mode. The first effective thermal conductively is lower than the second effective thermal conductivity.
