BS EN 16001 Energy Management System Implementation Case Study
Robert Wiseman Dairies
Robert Wiseman Dairies is the UK’s leading liquid milk company.
It procures, processes and delivers five million litres of milk every
day to several of the leading supermarket chains, as well as to the
independent sector. It operates from seven major processing dairies
in Aberdeen, East Kilbride, Glasgow, Manchester, Droitwich Spa,
Okehampton and Bridgwater.
The company holds certification to BS EN ISO 14001, and chairs the Dairy
UK Environment and Sustainability Committee and Dairy Energy Saving
Limited. It was involved in drafting DEFRA’s Sustainable Consumption
and Production Road Map setting out the future of the dairy industry,
and participated in Dairy UK and DEFRA’s anaerobic digestion trial using
effluent, animal slurry and poultry waste to generate energy.
The company takes pride in operating the most efficient and
environmentally friendly dairies in the country and is committed to
adopting good environmental practice at all its locations and in its
operational and capital investment decisions. For instance its new
dairy at Bridgwater led the company to investigate many new
technologies around reducing impacts, including incorporating
a rainwater harvesting system.
Robert Wiseman Dairies’ key objectives are to continuously improve
environmental controls; to continuously look for methods to reduce or
eliminate its environmental impact; and to use resources efficiently and
minimize waste production.

BS EN 16001 Energy Management System Implementation Case Study
Processing milk takes significant amounts of energy. On arrival at the
dairy it is pre-chilled and then put into a silo. The milk is subsequently
separated – taking out any impurities and separating out the cream –
and homogenized – which prevents a cream line from forming in the
finished product. The pasteurization stage involves heating the milk
to over 72ºC. The milk is then put into a refrigerated store, another
significant user of energy.
The company monitors all the energy consumption at its dairies very
closely as part of an energy management strategy. Weekly data is
generated on litres per kWh of electricity, and per kWh of gas. These
feed in to the calculation of litres of milk per tonne of carbon dioxide.
The company aims to continuously reduce the amount of energy it
consumes and to increase the number of litres of milk per tonne of
CO2 that it produces.
At the operational level, Mark Cassidy, Environmental Manager, sees
energy management working at a number of levels. Level one is
behavioural: very simple things like turning off lights and equipment
and keeping chill storage doors shut. The next level is maintaining
equipment, like compressors, separators and pumps, to run them at
peak efficiency. Next, it is important to purchase the most efficient
and most cost effective equipment. Finally, energy purchase, where the
purchasing team will aim to procure the best available price for energy.
He found implementing BS EN 16001 does require some minor
changes. Cassidy notes that work will need to be done to create
awareness at the dairies and depots; but the established
communications systems such as scheduled meetings and notice
boards are already in place. Understanding of legal requirements will
need to be reviewed to take the legal obligations for energy use into
account. Senior management involvement is already in place under
BS EN ISO 14001.
Learning and implications
Cassidy’s overall approach to the standard for now is pragmatic
and cautious. “We need to find out if it will work for us” he says.
Working with BS EN 16001 has not changed his thinking on energy
management and he’s also aware of alternative approaches. For
instance he references PAS 2050 which looks at the embodied carbon
of a product across its lifecycle.
Robert Wiseman Dairies is also currently working with the Carbon Trust
to develop an energy management plan. That said, Cassidy identifies
that the energy management plan on its own doesn’t take him the
whole way to carbon reduction. “Savings have been identified but there’s
no actual route map to guide you to how you will achieve those savings.
It’s really down to us to get it done.” This is where an energy
management system may come into its own.
Implementation approach
Robert Wiseman Dairies wanted to be involved in the trial
implementation of BS EN 16001 to get an insider view of the standard
and judge how much value it would yield. The company wants to
reduce energy use, but also to verify how much is being used: giving
a level of confidence that what the meters are reporting, what is
being invoiced and what is being used in reality, are all the same.
As noted above, the company has BS EN ISO 14001 certification. This
created a solid platform for work on BS EN 16001 – the new standard
was written to be complementary to BS EN ISO 14001 and both follow
the Plan-Do-Check-Act model.
Says Cassidy: “We found the 14001 paperwork can be easily adapted
for 16001. The first thing we did was take our environmental procedures
and draft a version with energy and environmental procedures, so
basically integrating the two standards together.” He adds: “We really
don’t see the need to have two completely separate systems. We might
require two separate policies, but certainly the actual mechanisms
within these systems, the sets of procedures for example, don’t need
to be duplicated.”
Benefits of the standard
Operating in a keen commercial environment, Cassidy is honest about
the key reason his organization would adopt BS EN 16001. He says,
“It’s about cost saving as well as reducing our carbon footprint and
has to be based on the principles of sustainability.”
A useful advantage for Robert Wiseman Dairies is that as the owners
of an already well-developed environmental management system,
the incremental effort of implementing BS EN 16001 is fairly small.
Drawing on his pre-existing experience with BS EN ISO 14001, Cassidy
found BS EN 16001 easy to work with: “Because I’m so familiar with
14001,” he says, “I know the language that’s used. 16001 is so similar
that it’s not a problem at all. I would say I found it simple.”
Finally, in Cassidy’s opinion, the fact that he can go for certification –
and thereby have energy usage and efficiency independently verified
– is definitely likely to have a value down the road. For now Robert
Wiseman Dairies is not large enough to trade carbon within the EU
ETS. Nor will it be liable within the Carbon Reduction Commitment this
time around. “But if the legislation changes, and the threshold comes
down, we might be,” he notes.

Conclusions
Cassidy believes that for him the main challenge of implementing the
standard would be to make sure that he strikes a balance between
having an integrated system and getting the most out of both
standards individually, with the minimum effort.
For now, working with the standard has started a lot of debate at
a senior level within Robert Wiseman Dairies about how it looks at
energy and how it records energy use. Cassidy says that historically
the company has never neglected water nor energy use, but
BS EN 16001 may bring the issues into a tighter, clearer focus. So
for them the incremental benefit of having BS EN 16001 in addition
to BS EN ISO 14001 lies in the focus on energy and in preparation
for the future.

Using the PDCA model
Energy management within BS EN 16001 is based on the Plan-DoCheck-Act (PDCA) model. ‘Plan’ includes establishing the objectives
and processes needed to deliver results in accordance with the
energy policy; the ‘do’ element concerns implementation, while the
‘check’ dimension includes monitoring and measuring processes.
The ‘act’ requirement focuses on the need to continually improve
performance of the energy management system.
“It’s about cost saving as well as reducing our carbon footprint
and has to be based on the principles of sustainability.”

About BS EN 16001 Energy management systems.
Requirements with guidance for use
With rising energy costs, energy efficiency has become an important
component of business efficiency and cost management.
BS EN 16001 Energy management systems. Requirements
with guidance for use provides a road map to help organizations
improve energy efficiency, reduce greenhouse gas (GHG) emissions and
drive down energy costs.
It is a best practice document that will allow businesses to implement
their own energy management systems and to get an appreciation of
their own energy usage. It explains what steps they need to take and
who they need to get involved in their businesses to help.
The standard applies to all energy-related activities under the control
of an organization. For example, it takes account of the power used
by machinery and the energy needed to heat office buildings. These
‘energy aspects’ represent elements of an organization’s activities,
goods or services that can affect energy use.
The standard can also be used to turn energy into a key performance
indicator alongside such elements as unit cost and customer satisfaction.
