Energy Management Auditing

Richard Hadfield

ISO 50001 Audit Guide 126

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 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 50001:2011

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.


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.


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


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

Energy Service

Key to understanding alternative strategies

Energy Service is:

A review of what the system is to achieve

Example: Energy service = raise temperature of x ml water from ambient to 100oC

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


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)

An energy balance can explain the overall efficiency of a

process

Review operation parameters

Examples:

Cycle times

Operating hours

Temperatures / Make-up air etc.

Flow rates / speeds

KEY: Understanding of safety / product

quality / required environment


Review of equipment

Examples:

Sizing

Run / standby / duplex sets

Maintenance routines

Leakage

Condensation / insulation

Controls

Pipe layouts / orifice plates etc.


Review of Design Parameters

used as low grade heating

understand potential

The ”composite”-

principle identifies:

- Improved supply

- Heat recovery

The ”composite”-

principle can be

applied also for:

- Compressed air

- Water/waste water

- Etc.

Temperature

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)

context of energy
