The Ventilation Window

At the bottom of the Ventilation Window, air enters through a shaft between the glass layers.
At the top, there is an electronic valve that opens and closes automatically based on the control system.

When the air inside the window warms up and the house needs heating, the valve sends the warm air inside.
If heating isn't needed, the outside air passes directly into the room, helping keep the indoor temperature stable.

The valve also adjusts automatically based on indoor temperature and humidity.
If either gets too high, the Ventilation Window system works to bring the air back to a healthy and comfortable level.

Built with wood on the inside and aluminum on the outside, so it can handle all kinds of weather.
Can be designed as the existing Windows and is available as fixed and top-turning
