Generally speaking, the HEMS systems available on the market require the installation of expensive dedicated devices and the management of the communication interface required to connect the smart appliances, without active involvement of end-users for the optimization and rationalization of their consumption.

Incentives to rewards worthy end-users (no power consumption or in suggested time slots) could be introduced, according to DSO operator, to encourage an environmentally sustainable behavior. Similar incentive mechanisms are already used by some DSO operators, such as the A2A’s ChiarA2A program , in which the ecologically-friendly behavior is rewarded by the accumulation of points that could be converted in vouchers for e-commerce.
To collect data about the energy consumption inside the building, the proposed system provides two different modes:
Automatic reading mode
It works in collaboration with on-site smart sensors, both building oriented (for example the main power line meter) and single supply point oriented (for example smart plugs with a built-in measurement system), the latter only if there is the need of measuring single appliances. At
- Electrical smart meters. The system is initially oriented towards optimizing electrical consumption.
Nonethelessit could be easily extended to acquire data from other meters already in use, such as the ones monitoring the gas consumption or the district heating. These measurements are needed in order to understand and to present to end-users the whole energetic impact of the building.
plugs. Smart plugs, both standalone and integrated inthe building electricitysystem, allow an easier monitoring of the energy consumption of appliances through the entire house. In some circumstances, it will be also possible to remotely enable/disable the power supply, through appropriate communication protocols.
- Disabling the power supply of unused appliances could help
reducinghidden consumptions, such as the stand-bypower. Smart appliances. The availability of smart appliances, able to communicate directly with the domestic central unit, can help optimizing power consumption by defining control strategies.
Manual reading and data entry
This working mode is provided for buildings without automatic reading systems such as smart meters or smart plugs. Of course, compared to the automatic input mode, this one provides a limited perception about energy consumption, since the data cannot be entered with too high frequency due to the manual data entry, but still allows to analyze long-term trends and highlight issues.
