I have thought about that if I am ever going to build a single floor house this is what I would do. I would make the whole roof out of glass (like a greenhouse). This glass roof would be made out of double glass with as much as 20 cm between the two. In this space I imagine that there would be a very dark curtain, which would stop sunlight in the case where the temperature inside the house gets too high (I am living in Scandinavia so this would just be the case for a few months per year). It would be possible to control the ventilation in the space between the glasses by opening sections of the roof.
The positive effects of this would be:
- Watching the stars from bed at night
- Feeling like one is outside the whole day if the curtains are away
- Less need for lighting
A part of the reason for doing this is that light is a precious thing in Scandinavia during the winter.
What am I missing here? Why have I never heard about such a house (bad research?)?
