I'm suggesting to our tribe that we build a geodesic dome for our new greenhouse rather than a standard tunnel greenhouse and they want to see that it has worked for others in this sort of geo-climatic region. Might anyone be able to link me to an example of a successful dome project in SE Alaska, Nova Scotia or the like?
Geodesic domes in general have proven to be susceptible to leaking, which is very bad for dwellings, maybe not so much for greenhouses.
A more pertinent factor might be that a dome cannot be oriented to take advantage of sunlight; its facets will all be at different angles and any sun control techniques or movable insulation would have to be individually tailored to every panel. A standard shape can have a single treatment applied to an entire side at once, which makes control simpler and possibly more effective. Also, glass cut into triangles would likely have a lot of waste, even more than plywood or other panel materials. If it didn't have a high waste factor, there would be even more joints in exposed surfaces.
The glass is neither half full or half empty. It is too big. But this tiny ad is just right:
