Thus, there is a possibility that only a fraction of the present warming trend may be attributed...

The rational thermal management of buildings is major importance for the reduction overall primary energy consumption. Smart windows are promising systems which could save a significant part this energy. Here we introduce double glazing system made with thermochromic metal-insulator transition material and glass layer separated by an air gap able to switch from its insulating conducting phase t...
