Dilip Rahulan believes that buildings, infrastructure and transport use far too much energy today. We keep heating, cooling and illuminating buildings, even if it is not necessary: “When a building designed for five hundred people is only occupied by ten, the air conditioner is still going at full blast.” Energy could often be saved without losing comfort – but this requires intelligent software solutions, which allow the electronic devices in the building to exchange information. This strategy works even better when whole cities or countries are connected in a network of information exchange. The internet and mobile phones have revolutionized the way people communicate. In a similar way, an “internet of things” could revolutionize our technology, enabling devices, computers, data bases and information networks to exchange information.
