Smart Houses

What is a Smart House?

A Smart House is a home that uses ICT to control energy supply and demand. This creates a more pleasant living environment and enables residents to save energy and lower electricity bill payments.

Visually representing household energy consumption enables the residents themselves to save energy more effectively. It also facilitates effective energy use through energy storage.

Next-generation housing that balances both environmental and economic considerations for smarter, more comfortable living – that's what the Smart House is all about.

Supporting the Smart House: HEMS and Residential Energy Storage Systems

Home Energy Management System (HEMS*) and residential energy storage systems play vital roles in a Smart House. By visually representing power consumption and CO2 emissions data for every room, houses equipped with HEMS can help households limit energy consumption while providing a comfortable living environment.

Furthermore, combining solar power generation with a residential energy storage system supports efficient energy usage by effectively using solar energy that is generated or stored and balancing supply and demand to and from the grid network.

*Home Energy Management System (HEMS*)
This system automatically collects precise real-time data on power usage by room and presents it visually. This naturally heightens user awareness of energy saving and helps realize a reasonable, comfortable, eco-friendly lifestyle.

NEC's Initiatives

NEC is working to develop HEMS and residential energy storage systems.

Going forward, we will enrich various existing services through collaboration with different industries as well as the automated operation of various home appliances.
