Future smart cities and buildings could bring several benefits to life, such as reducing waste, driving power efficiencies and enhancing resources, but it also comes with some challenges, with security issues being the most significant.

That solves a need in a simple way, but without any thought on the bigger picture of future needs and re-use of infrastructure and data. Complete vendor and data lock-in.
