Lecturer of architecture, University of Loughborough (UK) Mathias gutai group has developed a new type, whose glass is filled with water. Normal Windows have a typical “seasonal” problems – in the winter they do not keep warm, and in summer warms in the sun, passing into the room unnecessary heat.

Internal glass Windows, designed by the gutai group, filled with water. While passing through the sunlight heats water, which prevents the penetration of heat into the room. Once the water temperature reaches a certain point, it is pumped into a special tank, but instead pumped cold water.

When the temperature outside drops, the accumulated warmer water in the wall mounted heating system and warms the room. The heated water can also be used for household needs.

According to Mathias Guta, despite the fact that the transfer pump requires some amount of electricity, these costs are still less than the costs of running heating and air conditioning.
