BS EN 16247-1 Energy audits. General requirements
Using BS EN 16247-1 to structure a better energy audit
process and help realize significant carbon and cost reductions
Following the BS EN 16247-1 standard, EDF Energy delivered an energy
audit for the Marine Biological Association (MBA).
“By working to the new standard
for energy audits, we were able
to implement a standardized,
clear process for delivering
consistent audits.”

BS EN 16247-1 Energy audits. General requirements
Why use BS EN 16247-1?
EDF Energy is one of the UK’s largest home
and business energy suppliers. Its Energy
Services team helps business customers
save energy, money and emissions by
delivering programmes of energy
conservation measures. The first step is to
conduct an energy audit to identify what
measures are appropriate, and where the
largest savings can be made. The EDF
Energy team chose to work with the new
BS EN 16247-1 standard both as a way
to check and improve its current audit
processes, and as a means to assure to
its client that they were receiving a high
quality, cost-effective audit.
About BS EN 16247-1
BS EN 16247-1 is a European standard
that sets out the best way to conduct
an effective energy audit. Energy
audits are an important tool for any
organization that wants to understand
its current energy use and reduce
consumption. Audits can also help
organizations meet increasing energy
and environmental obligations.
The standard was written with
input from recognized energy experts.
It defines the attributes of a good
quality energy audit, from clarifying
the best approach in terms of scope,
aims and thoroughness, to ensuring
clarity and transparency.
Of course for many years there’s
been a range of interpretations of
how energy audits can best be done.
What BS EN 16247-1 supplies is a
consistent and reliable approach,
so that recommendations can be
implemented with total confidence.
BS EN 16247-1 is appropriate for
all organizations regardless of
size or industry sector. It provides
a management tool for energy,
sustainability and environmental
managers, as well as for auditors,
consultants and senior management
interested in targeting energy
efficiency, both for commercial
and environmental benefits. It also
complements the internationally
recognized energy management
system standard, ISO 50001,
and can be used to undertake
a comprehensive energy review.
The Marine Biological Association (MBA) is
a charity, and a leading marine biological
research organization that has earned an
international reputation for excellence and
research innovation. For its part, the MBA
wanted to find out the available
opportunities to reduce its carbon
emissions and its energy costs.
Conducting the energy audit
In 2013 the MBA asked EDF Energy to
conduct an energy audit at its Plymouth
Laboratory. The site has a number of key
buildings that include a main office block,
laboratories and the National Marine
Biological Library. The building utilization
and the energy intensity at the site are
relatively low, but as an ecological charity,
the MBA wanted to understand what could
be done to reduce its site’s carbon
emissions and energy costs.
EDF Energy’s audit involved six days of
work, including a site visit which consisted
of an assessment and review of the energy
usage on the site and the identification of
opportunities for improving energy
efficiency. Following the site visit the EDF
Energy engineers analysed the data and
developed a report on the results that was
presented in person to the MBA.
The audit identified that the key consumers
of energy were lighting, IT rooms (servers
and air conditioning), and fridges and
freezers. Subsequently, six improvement
measures were presented back to the MBA,
three of which required no investment to
produce energy savings. The other three
measures covered insulation; energy
monitoring and behaviour change; and
solar photovoltaics (PV). The identified
measures were calculated to provide an
overall annual energy saving of 17 per cent
of the current energy bill, with a payback of
four years, and carbon savings of 46 tonnes
per year.
How using the standard made a difference
EDF Energy chose to use BS EN 16247-1
because the standard gave the Energy
Services team an opportunity to revisit its
internal processes and redefine them in line
with suggested best practice. An initial gap
analysis identified areas for immediate
improvement and subsequently, using
BS EN 16247-1 as a guide, the team
standardized the stages both in their
internal processes and in the final product.
By using BS EN 16247-1, EDF Energy
provided MBA with a clear process for
delivering the audit. This included a
teleconferenced start-up meeting which
gave EDF Energy both the chance to
introduce its Energy Engineer at an early
stage in the process, and to resolve any
issues before visiting the site.

The process also provided for different
ways of communicating with the client.
For example, the team engaged the MBA
from the beginning on their reasons for the
audit and their objectives. Templates and
checklists were used to ensure consistency,
and that processes were being followed.
It led to on-going reviews with the client,
and a final presentation of the results that
included the MBA’s key stakeholders.
EDF Energy found that the standard gave a
structure for it to request information from
the client – previously found to be one of
the more challenging parts of the energy
audit. It also meant that the team felt more
comfortable requesting information at an
earlier stage. This ultimately benefitted
the MBA too as the whole process ran
more efficiently.
“The standard reduced
unnecessary delays waiting
for the right people to have
the right information.”
EDF Energy noted that the most beneficial
part of working with the standard was
getting key stakeholders involved from the
beginning. This helped ensure that timely
decisions were made, and resulted in a
more streamlined process for both parties.
Overall the standard made sure that the
output from the energy audit provided
value to the MBA and helped it determine
its strategy for managing energy efficiency
going forward. “Identifying opportunities
alone doesn’t realize tangible savings for
BS EN 16247-1 Energy audits. General requirements
our clients. They need to choose which
measure to implement and then manage
a programme to do so,” noted Sam Moore,
Energy Services Partner at EDF Energy.
“Too often,” he continued, “the Energy
Manager struggles to get investment in
projects, even where the numbers clearly
show savings.” The process suggested by
the standard reduced unnecessary delays
waiting for the right people to have the
right information.
Benefits from using BS EN 16247-1
The standard brought much more
consistency to EDF Energy’s audit process
and inspired the team to improve their
processes further. There is now greater
communication with the client, greater
sharing of information, and client feedback
is requested on the process and finished
product. The standard also led EDF Energy
to put much more focus on helping its client
push projects through internally – helping
bridge the traditional barrier between energy
managers and financial decision makers.
Overall the MBA was very impressed with the
expertise of EDF Energy’s engineers, with the
way the audit was delivered, and the
thorough approach taken to considering a
wide range of energy saving opportunities.
Jon Parr, Deputy Director of the MBA, said:
“The service delivered was very professional
and the ongoing client contact throughout
provided us with reassurance that the results
would match our expectation, and confirmed
we were getting value for money.”
“It provided us with reassurance
that the results would match our
expectation, and confirmed we
were getting value for money.”
The Energy Services team at EDF Energy
now conducts its energy audits in line with
BS EN 16247-1. The actual audit has not
changed, but the process and end-product
have greatly improved the customer
experience, as evidenced by the positive
feedback received to date.
The EU’s Energy Efficiency Directive
About BSI Standards
About BSI
The EU is not currently on track to meet
its target of reducing energy consumption
by 20 per cent by 2020. As a result it
introduced an Energy Efficiency Directive
in 2012. The Directive imposes a duty on
energy utilities to encourage end-users
to cut their energy consumption through
efficiency improvements. It also requires
large companies (firms with 250 employees
or more) to do an energy audit every four years.
