If you want better cities, goes the theory herein, you'll have to start at their very foundations. Steve Lewis, ex-Microsoftie and current CEO of Living PlanIT, has a vision for how to make our cities smarter and more sustainable, and it starts literally at ground level, with the installation of smart sensors into buildings as they're being built. The appeal of his company's ideas has already attracted some tech luminaries as partners, Cisco being among them, and now Microsoft has also been signed up -- to provide the cloud framework required to keep all those sensors talking with its Azure platform.
