Scope
These slides cover the two main areas
The energy review
Operations
Other areas are regarded as generic to
management systems although with an
energy emphasis
ISO 50001 Audit Guide 127
ISO 19011:2011
The auditing process is covered by ISO
19011:2011
For certification (3rd party), this is covered
by ISO 17021:2011 and competence
requirements are in preparation.
These are regarded as generic
ISO 50001 Audit Guide 128
ISO 50001:2011
KEY: A full understanding of the way
energy is used within the scope and
boundaries of the EnMS
For this one needs knowledge, skills
and good judgement.
ISO 50001 Audit Guide 129
Integration
Although energy management is distinct
from environment, quality or H&S, many of
the same techniques can be used and
there is opportunity for existing tools to
be used for EnMS either by adding energy
aspects or directly for energy.
ISO 50001 Audit Guide 130
Knowledge
Basic knowledge about energy
Understanding of buildings and their systems
Understanding of industrial systems
(compressed air, steam, chillers, vacuum, fluid
distribution, heat exchangers, boilers, reverse
osmosis DI water etc.)
Understanding of alternative energy sources
Understanding of tariff structures and energy
agreements
ISO 50001 Audit Guide 131
Key laws of physics
Laws of thermodynamics Energy can neither be created or destroyed
Flow of heat is energy transfer
Work is a form of energy transfer
Heat flows from a hotter to a cooler body
(entropy
Fourier’s Law – conduction
Exergy – available energy

From Energy Service to Energy Bill
1. Reduce the ”Energy Service”
2. Use energy efficient technology
3. Optimise efficiency of plant and technology
4. Ensure a correct operation of the plant
5. Re-use waste/excess energy
ISO 50001 Audit Guide 139
Energy Service
Energy Consumed
What is needed to provide the energy service in theory
What energy is consumed in reality
Example:
Removal of Cement Dust from Cement-Bags
1. ”Energy Service” = removal of cement dust
2. Technology = compressed air vs. ”mechanical” solution
3. Efficiency = minimize pressure needed etc.
4. Operation = minimize idle load etc.
5. Re-use of waste = utilise excess heat for building
heating (compressor waste heat)

- Etc.

Energy Content
Example: Heat Recovery Large waste heat ammounts in most
industrial sectors
In food sector, pharmaceutical sector etc.
large ammounts of waste heat has
temperatures < 100C
The most easy solutions might be utilised
already (building heating)
...but large hidden energy demands might
be found in heating of water for processes
and cleaning purposes etc.
Use the composite-principle
Establish water/heat storage (70 C)
