Honda Motor Co., Ltd. today unveiled a house Honda built in the city of Saitama, Japan, for the demonstration testing of the Honda Smart Home System (HSHS).

The house features HSHS, which comprehensively controls in-house energy supply and demand, and helps manage both the generation and consumption of energy for the home such as heat and electricity, while utilizing mobility products.

The house also features Honda’s gas engine cogeneration system.


The gas-engine cogeneration system is an energy device which makes a significant contribution to the reduction of CO2 emissions by enabling efficient generation and consumption of heat which accounts for approximately 60 per cent of the energy consumed in a typical Japanese home, primarily for hot water supply, heating and kitchen needs.

Featuring a unique multi-link type high expansion ratio engine, EXlink (Extended Expansion Linkage Engine), Honda’s gas-engine cogeneration system offers combined efficiency — the combination of power generation efficiency and heat recovery efficiency — of 92 per cent and enables the efficient use of electricity and heat using city gas or liquid petroleum gas.

In demonstration testing, Honda will study the automatic activation of the cogeneration unit using a battery and verify its effectiveness in the time of an emergency.
