What do we aim for?
Building capacity among public authorities on Article 3 & Article 7
of the Energy Efficiency Directive:
streamSAVE builds capacity through the creation of an open dialogue that
focuses on streamlining calculation methodologies to estimate bottom-up
savings and cost effectiveness of technical energy savings actions. The
project targets priority actions i.e., new actions with high energy saving
potential and considered as a priority issue by national public authorities.
Address additional efforts in EU Member States in realizing energy
savings by 2030 under Article 3 & Article 7 of EED.

What do we aim for specifically?
Streamline methodologies to estimate energy savings of 10 priority actions to
answer the need for comparable progress reporting, while acknowledging
diverse Member States’ realities. GUIDANCE ON STANDARDIZED SAVING METHODOLOGIES
Peer-to-peer capacity building through dialogue and capacity support to
address Member States needs:
– Cooperative community of technology group experts, public authorities and other market
actors centered around each priority action.
– One-to-one technical assistance: providing evidence-based support on streamlined
savings calculation to the 10 partner Member States.
Sustainability and replicability of streamSAVE outcomes: lively community and
active streamSAVE platform beyond the life of the project

`Five actions fit for 55: streamlining energy savings calculations´
Views from the EU Commission and the link with Fit-for-55
8 December 2021 Anne Weidenbach, Policy Officer,
Energy Efficiency Unit, DG ENER,
European Commission

Annex V(1) EED 2012/27/EU as amended by Directive 2018/2002
Calculation methods provided
“Obligated, participating or entrusted parties, or
implementing public authorities, may use the following
methods for calculating energy savings:
(a) deemed savings, by reference to the results of
previous independently monitored energy
improvements in similar installations (…)
(b) metered savings (…)
(c) scaled savings (…) This approach may be used
only where establishing robust measured data for a
specific installation is difficult or disproportionately
expensive (…)
(d) surveyed savings (…). This approach may be
used only for savings resulting from changes in
consumer behaviour. It shall not be used for savings
resulting from the installation of physical measures.”
Possibility to use standardised
calculation methods, applied with data
specific to each energy saving action
or project
Standardised energy savings for
standardised action types

Different methods for different purposes
Calculation
method
Deemed savings Scaled savings Metered savings
Cases where
it is
commonly
applied
• Large number of
similar actions (that
can be described in a
standardised way)
• Collecting specific data
for each action could
be difficult or
expensive (compared
to the energy savings
achieved)
• Intermediate number of
actions partly similar /
partly specific
• Collecting energy
consumption data could
be difficult or expensive,
but some specific data
can be collected at a
reasonable cost
• Large actions or projects, that
can be very specific
• Amount of energy savings high
enough (usually >10%) to be
distinguished from other
changes in metered energy
consumption
• (Sub-)metering of energy
consumption doable at a
reasonable cost or needed
anyway
This categorisation might evolve in future

Advantages and limitations of each method
Calculation
method
Deemed savings Scaled savings Metered savings
Advantages • Low monitoring cost
• Visibility to market actors
(values available beforehand;
catalogue of energy saving
actions), for example in
EEOS, voluntary
agreements, …
• Reasonable compromise
between reliability and M&V cost
• Address specific actions
• Useful for M&V of a policy
measure and for project
planning (investment certainty,
e.g. through energy audits)
• Provides results that reflect the
actual energy savings achieved
by each action or project
• Useful for M&V of a policy
measure and for project planning
(investment certainty, e.g.
through energy audits), especially
when (sub-)metering in place
anyway
Limitations • Requires actions that can be
described in a standardised
way
• Requires reliable and
detailed national data to
define the deemed savings
• Average values risk to not
reflect individual cases
• Possible gap between the
average values used to
define the deemed savings
and the average of reported
actions
• Might result in high
administrative costs in case of
large number of actions (or
require a dedicated IT system)
• Costly depending on the data to
be collected
• Requires experts, training or
guidelines to ensure reliable
calculations
• Requires sound verification of
calculations (but possibility in
some cases to use automated
checks)
• Costs might be disproportionate
for small actions / small amount
of energy savings
• Data needs go beyond energy
consumption (e.g. weather
conditions, production volumes)
• Expertise required to verify
energy savings and changes in
energy consumption for other
reasons
• More complex to verify
• Data confidentiality to be ensured

Documentation of deemed savings is key
Annex V(3)(c) EED 2021/27/EU as amended:
`energy savings that are achieved or are to be
achieved are determined in a transparent manner´
Annex V(5) EED 2021/27/EU as amended:
`Notification of methodology
(…) notification shall include details of:
(g) the calculation methodology, including how
additionality and materiality have been determined and
which methodologies and benchmarks are used for
deemed and scaled savings;´
See also point (4) in Annex III of the Governance Regulation
Documentation is key to comply with reporting
obligations and to allow for regular & sound
review and update of the deemed savings
methodology
Example of good practices:
Revise and update
catalogue of deemed savings regularly;
consult stakeholders to ensure legitimacy of
the deemed savings

Objectives of the EED revision
Reap unexploited energy
savings potential across the
economy
Reflect the increased energy
efficiency ambition from the
Climate Target Plan
Provide Member States
with measures compatible
with the increased ambition
towards 2030 climate
target 55%
Energy efficiency is a pre-condition for all decarbonisation scenarios of the Climate Target Plan

Main elements of the EED
Binding EU energy efficiency target & indicative national contributions
‘Energy Efficiency First’ Principle – making it an integral part of policy and
investment decisions
Strengthened energy savings obligation in end-use
Stronger exemplary role of public sector
Increased focus on alleviating energy poverty and consumer empowerment

Real world solutions for electro mobility?
Independent measurement & verifications are rare
Supplier references are useful but not enough
How were the savings calculated, greenwash or IPMVP*
We need a shorthand / reference upon which to base investment decisions
*International Performance Measurement and Verification Protocol (IPMVP)

An industry example; the GLEC* Framework
A global common language for units, factors
and calculations (soon to become ISO14083)
• Use GHG emissions as a metric for
sustainable freight transportation decisions
• Make or influence decisions around supply
chain optimization
• Manage the performance
• Evaluate the impact of measures
• Track progress towards your climate goals
• Inform on emissions reductions achieved
*Global Logistics Emissions Council - https://www.smartfreightcentre.org/en/how-to-implement-items/what-is-glec-framework/58/
