Wireless sensor start-up Arch Rock has come up with a system of wireless sensors that will give comprehensive information about a building's energy consumption without laying down new wires.
The system, which costs thousands of dollars, is not fit for small companies who are cash-strapped. However, for larger corporations, it is said that this can bring savings of around 10%-20% on electric bills.
