Environmental & Energy Activity Efforts in the Environmental and Energy Businesses

NTT West Group offers a diverse array of services that make use of ICT to promote protection of the global environment as well as energy-saving by the society.
In FY 2015, we have launched the HEMS service that utilizes the Hikari BOX+ information equipment. Also, the "Eco Megane" service, which was previously offered to households for monitoring solar power generation remotely, is now extended to PPS. Please see below for more details.

[Service Overview]
Hikari BOX+ (EMS version) is a HEMS controller that supports connection to a smart meter, which enables visualization of power consumption by utilizing devices such as a TV monitor or smartphone, as well as control of home appliances such as air-conditioners and electric water heaters. With the addition of this new feature, connection with Eco-Jozu(*), a high-efficiency gas water heater, is now supported, and it can be used to monitor the operation and status of hot water supply and floor heating.
