Promotion of High-Efficiency Boilers

Energy demand for hot-water supply dominates about 30% of the total energy consumption in a household.

A rebate system has been introduced to promote the proliferation of energy efficient hot-water systems.

CO2 Refrigerant Heat-pump Boiler

Utilizing the principle of a heat pump used in an air-conditioner, it can be heated with energy of about 3 times more than input energy. This realized energy saving of about 30% compared to traditional combustion-type boiler.

Latent-heat Recovery Boiler

It recovers latent heat of exhausted gas, which was usually wasted. This realized energy saving of about 15% compared to a conventional combustion-type boiler.

Gas Engine Boiler

Use the gas-powered enginefs exhaust heat and power to provide heat (main) and electricity (sub) for approx. 10 overall energy saving for a building.

II-2(3). Energy Conservation Measures for the Transportation Sector

Promotion of Cars with the gIdling-Stoph System

Idle-free driving can improve fuel economy by approx.10%.
Even greater energy conservation effect is expected in city areas, where idling frequency is high.
Partial subsidy for the purchase of cars equipped with the gidling-stoph system was introduced in FY2003.
Promotion campaigns for the gidling-stoph systems are held in the forms of PR events, etc.

PR activities
In October 2003, an event for gidling-stoph experiments took place at Tokyofs Ginza and Osakafs Shinsaibashi traffic lights.

Fuel Economy Disclosure and Labeling System for Vehicles

The system was introduced in January 2004 to deepen consumer interest/ understanding on fuel economy and promote cars with high fuel performance.

Disclose Fuel Economy Performance
The disclosure is targeted for cars of which fuel economy standards are set based on the energy conservation law.
Either the status of "fully compliant" or gplus 5% of the fuel economy standardh will be publicly displayed.

Label a Fuel Economy Identifiable Sticker
Label a sticker on the body of a car that conforms either to "fully compliant with the fuel economy standard" or "plus 5% of the fuel economy standard".

Energy conservation law target year	FY2010	FY2005
Vehicles subject to the energy conservation law	Gasoline passenger/freight vehicles/ LP gas passenger vehicles	Diesel passenger/freight vehicles
Models plus 5% of the fuel economy standard
Models compliant with the fuel economy standard
