Basic Structure of Energy Conservation Policy

Incentives

• Subsidies for introducing equipment

• Tax incentive• Subsidize interest

payment• Subsidize R&D

Regulation

• Energy Conservation Law

• Mandatory Labelling

Subsidize 1/3 of the total cost on purchasing energy-efficient equipment and repairing.

Not only big companies factories but also small companies and offices such as hospitals utilize the subsidies.

1. Top Runner Program.2. Set energy efficiency standards for new buildings and houses. (will be mandatory for large-scale buildings to comply from 2017.)3. Requires companies to measure their energy consumption and report

it to Government.

3) Annual reports to the Government by business operators with 1,500 or more kl/yr energy consumption 15,000 manufacturing plants & officesReduction efforts of 1% per year

2) Energy efficiency standards for buildings and houses

1) Top runner standards for household appliances , equipment, automobiles etc.

Judgment made with weighted average for each product category.

The program requiring manufacturers and importers to fulfill the efficiency targets within 3 to 10 years.

Targets are set, based on currently commercialized products with best energy consumption efficiencies, namely top runner products.

Encourages competition and innovation without price hike.Image of Top Runner Program
