How to Calculate Eei?

EEI = AEc / SAEc
Measured Energy consumption of model x (kWh/year) The reference: 'Standard Energy consumption' (kWh/year), depending on volume (and more?)

How energy rating is calculated?

Use the Energy Rating Label to work out rough running costs with some simple maths. It's easy – just take the energy consumption figure – and divide it by 4. For example, if the Energy Rating Label on a washing machine says it uses 400 kWh, it means it will roughly cost you $100 per year to run.

What is the energy efficiency index?

Energy efficiency index of industry (ODEX) is a weighted average of the specific consumption index of 10 manufacturing branches; the weight being the share of each branch in the sum of the energy consumption of these branches in year t and the sum of the implied energy consumption from each underlying industrial ...
