Shut down buildings to save upkeep cost?

Is it possible to shut down buildings to save their upkeep cost?

Some buildings, particularly research facilities are only useful for a limited amount of time, but they keep consuming massive upkeep resources. So I was wondering if there is a way to disable them when they are not researching anything.

I think you can’t shut them down, and if you lose the research facility you will lose access to the tech.

Yeah, I agree. Or some way to recover from losing other support buildings. Sometimes it all comes crumbling down the moment some of the economy buildings are lost.
