MULTI has yet to be installed in an actual building and from what I recall, they believed it would likely be used in new buildings that are designed with MULTI in mind rather than retrofitting older buildings. It seems like a good use case in my mind, though I don't expect it would be implemented for at least several years while the new technology is adapted and tested in real-world scenarios
