It derives from the ecobalance and has the ambition to analyze and verify the emergence, transformation and use of energy resources in an organization in detail.
[3] The basic idea of a balance is that nothing can get lost or annihilated - this fits to the first law of thermodynamics, which assigns energy this property.
But energy splits up during usage and its output does not have the same potential for the physical performance as before.
[4] For this reason it is important to distinguish between input and output of energy usage.
But on the output side there may be effects that are difficulty predictable, such as heat, dust or noise.
