Due to more stable temperatures, these unconditioned areas around the building reduce heat losses during the heating season and present better overheating protection in the summer. In this concept the exterior skin protects building from the weather conditions and the interior skin gives thermal insulation. This paper presents the concept and the simulation results run in order to determine its influence on building energy demand.

This method was used to test a model of the concrete wall with the material inclusions with significantly different thermal properties. The study performed in climatic chambers consisted of heating the model wall with a 7.2 kW heat pulse, and then recording the thermograms during wall cooling, at regular intervals, using a thermal imaging camera. Based on the recorded temperature distribution on the thermograms the thermal properties and location of subsurface defects were concluded.
