An eco-village need maximum efficiency to prevent wasting of any of its resources. This actually implies that it should be run by a AI, who constantly monitors all of the systems. It may look a bit dystopian, but if this AI can’t switch off the life support or lock the doors (usual fiction pitfalls!), plus there is a back up manual way of running things smoothly, why not? Why not use the technology which would save energy and time? Good for people, good for the environment.
