I’d love to be in the room when their mechanical engineers tells them how many tons of air conditioning that’s going to require, and how much that will cost both for installation and operation.
It looks like yet another completely impractical architect’s wet dream from here.
Interesing...
Does it Rain in Seattle (sarc?) Another big issue that I see is the glazing on the glass “roof” panels. How long before they start to leak. This can be a problem in Geodesic dome structures. I suppose there may be some innovative way to overlap the glass panels like shingles, shiplap, or fish scales to avoid this.
I suspect that the interior will develop its own little climate. As you indicate, there will be a lot of work on the HVAC systems to prevent problems with condensation and overheating in this upside down terrarium bowl.
