Is it any wonder that there are a lot of smart ideas for smart cities? That may be because a smart city is – by definition – an ideas city: a city built upon past or current ideas, as well as upon openness to future ideas: to future city ideas. Smart city ideas are often participatory: urban connectivity schemes like a better biking infrastructure or multi-directional elevators. And ideas for making the smart city smarter immediately become part of the public domain, texted to friends, discussed on social media, flash-mobbed by supporters, and analyzed at the neighborhood rooftop garden.
The future’s nearer than you think: we already have all the technology needed to construct residential and commercial buildings that generate at least as much energy as they consume – or more! URBAN HUB looks into “net-zero energy”, and visits several projects using this intriguing new concept.
