“On this episode of Futuris, we look at groundbreaking new technology that could hold the key to energy-efficient buildings of the future. We went to Sofia, Bulgaria, to find out how it works.
They look like ordinary windows but they’re not. Inside each pane, there is a continuous flow of distilled water and glycol. The windows have been designed by researchers and architects working to create the energy-efficient buildings of tomorrow. The technology is being tested at an experimental pavilion in Sofia.
Inside each window, there is a constant flow of 70 litres of distilled water and 30 litres of ethylene glycol, which serves as antifreeze. Each transparent panel acts as an individual solar collector. Using solar cells, the windows absorb solar radiation and turn it into thermal energy to heat the building’s interior…”
