Introduction
Energy efficiency improvement is one of the pillars of the energy transition. It is considered as one of the
most cost-effective ways of addressing the growing demand for energy, climate change mitigation, energy
security and increased competitiveness.
Directive 2012/27/EU on energy efficiency defines the term "Energy Performance Contracting" as “a
contractual arrangement between the beneficiary and the provider of an energy efficiency improvement
measure, verified and monitored during the whole term of the contract, where investments (work, supply
or service) in that measure are paid for in relation to a contractually agreed level of energy efficiency
improvement or other agreed energy performance criterion, such as financial savings”.
NOTE Sometimes in English the term "Energy Performance Contracting" is used with the same meaning of
"Energy Performance Contract" although "contracting" can refer to the process of establishing and delivering an
energy performance contract.
The new energy efficiency directive (EU) 2018/2002 highlights that reaching an ambitious energy
efficiency target requires barriers to be removed to facilitate investment in energy performance
improvement actions (EPIAs). One step in that direction is the clarification provided by Eurostat on how
to record energy performance contracts for the public sector in national accounts, which offers
opportunities to remove uncertainties and facilitate the use of such contracts.
The lack of broadly accepted best practices or guidelines for Energy Performance Contracts (EPCs)
demands the development of a standard specifying the minimum requirements of the contractual
agreement that matches the needs of:
• policy makers to provide tools for quality, transparency and effectiveness in EPIAs;
• building owners, public or private organizations and energy service providers to adopt a contractual
framework for energy services that provides clear and transparent risk allocation and guaranteed
energy efficiency improvement and other agreed energy performance criteria;
• financial institutions and banks to have a reference contractual framework between user and energy
service provider that clearly specify value generation (including multiple benefits or co-benefits of
energy efficiency improvements) and risk allocation;
• property valuators to help assessing the value of the asset in relation to its energy efficiency and
sustainability performance for the project lifetime.
This standard addresses the multiple domains of the EPCs: technical, financial, legal and provides a
common framework of methods to integrate the minimum requirements of energy efficiency
improvement.
Because an EPC usually has an impact on the risk allocation between the energy service provider, the
financial institution and the beneficiary of the energy efficiency improvement services, the requirements
have implication on the economic evaluation, legal, fiscal and accounting procedures for both public and
private organizations.
This document can be used in conjunction with the following:
• management system standards,
• energy management standards,
• risk management standards,
• asset management standards,

---------------------- Page: 6 ----------------------
SIST EN 17669:2023
EN 17669:2022 (E)
• underwriting procedures of financial institutions (European Bank Authority – EBA),
• international accounting standards (International Financial Reporting Standards - IFRS),
• Eurostat statistical treatment of EPC,
• Environmental Social and Governance (ESG) requirements, or
• Action plan for Sustainable Finance.
The production of renewable energy on site does not necessarily achieve energy efficiency improvement.
Even if energy consumption across the boundary decreases, there may be no measurable improvement
in energy efficiency related to the energy use as a result of the change.
However, renewable energy production may be a component of an EPC and is therefore considered to be
in the scope of this document when combined with an EPIA.

1 Scope
This document specifies the minimum requirements for Energy Performance Contracts (EPCs). The
energy performance improvement actions (EPIAs) are intended to achieve a guaranteed level of energy
efficiency improvement and other agreed energy performance related criteria irrespective of the
quantity, use, or types of energy consumed.
This document is applicable to EPIA(s) on existing assets.
The requirements are set in order to provide:
• transparency throughout the whole process of establishing an EPC,
• cost effectiveness in relation to the benefits generated by the EPIA,
• a quality assurance, risk mitigation, and risk allocation toolkit,
• material information necessary for financial and technical calculations for both the beneficiary and
the energy service provider.
The document is applicable to energy service providers and beneficiaries regardless of their type, size,
complexity, or geographical location.
This document may be used by financial institutions and other stakeholders of the process.
NOTE This document could be used in conjunction with Eurostat or International Accounting Standards Board
(IASB) guidance or other standards to comply with taxonomy and non-financial reporting directive or Corporate
Sustainability reporting if applicable.

SIST EN 17669:2023
EN 17669:2022 (E)
f) meet the beneficiary energy performance requirements related to the expected service.
The scope and boundaries of the EPC shall be defined.
The scope of the EPC shall be described in an exhaustive and unequivocal way.
The boundaries within which the EPIAs shall be implemented shall be described including the energy
types for each energy use and the detail of each individual action.
The energy efficiency improvement achieved by the implementation of the EPC shall be demonstrated
through measurement and verification.
5 Energy targets of the EPC
The EPC shall specify the guaranteed energy targets to be achieved during the contract duration. Energy
targets shall be measurable and associated to relevant EnPIs. Each EnPI should be related to a
contractually agreed baseline.
Energy targets shall be expressed in the same units as the relevant EnPIs specified in the baseline. The
change in an EnPIv can be expressed as an absolute value or as a percentage.
The energy targets shall include the service level to be achieved.
The EPC can also include other objectives such as (non-exhaustive example list):
• environmental: GHG emissions or other emissions reduction objectives;
• reduction in costs;
• improvement in safety measures;
• improvement of earthquake building code implementation.
EPC investments, operational costs, and economic profit for the energy service provider are paid for in
relation to a contractually agreed level of energy efficiency improvement or other agreed energy
performance criteria or financial savings.
The economic evaluation of an EPC is assessed using a global valuation method and over the long term
(for example using EN 17463 Valuation of Energy Related Investments (VALERI)).
NOTE Additional objectives set in the EPC and that do not lead to savings directly connected to energy
efficiency savings are generally paid in relation to other criteria specified in the EPC.
An EPC shall include, as a minimum:
a) a description of the EPIA(s);
b) the ex-ante EnPI related to the boundary of the EPIA(s);
c) the relevant variables and static factors and a statement on the need to update them during the
contract lifetime;
d) an algorithm that correlates the EnPI(s) with the relevant variables and static factors;
e) the guaranteed energy efficiency improvement in relation to relevant variables and static factors
for the whole contract duration;
f) the methodology for measurement and verification and the frequency (at least annually) and
content of the reporting to assess the energy efficiency improvement over time;
10
---------------------- Page: 12 ----------------------
SIST EN 17669:2023
EN 17669:2022 (E)
g) the value of the investment committed for the implementation of the EPIA(s);
h) the responsibilities and payment allocation for the energy supply;
i) the ownership of the EPIA(s) asset(s);
j) the responsibilities and the allocation of costs for operation, maintenance and repairs for the
whole contract duration of the EPC;
k) a description of compensations, penalties or remedies (financial, technical or other) where
achieved savings fall short of the annual guaranteed energy saving, and one or more clauses
dealing with any eventual early termination of the contract;
l) a description of bonuses or other benefits where achieved savings exceed the annual guaranteed
energy saving;
m) the definition and beneficiary of any kind and form of applicable incentives (economic, financial,
fiscal, etc.);
n) the identification of EPIA’s implementation risks and their mitigation and allocation;
o) the contract duration;
p) a clause that allows the parties to manage justified changes in one or more of the previous items,
if required.
6 Contractual energy baseline
The contractual energy baseline is a value for a reference period that appropriately represents the range
of operating conditions ex-ante implementation of the EPIA(s). This enables changes in energy
performance to be accurately represented by comparing EnPIv(s) for the reporting and baseline periods.
The type of information needed to establish an energy baseline is determined by the specific purpose of
the EPIA(s), and by the effect of relevant variables on energy performance.
The EPC shall specify an exhaustive, qualitative, and quantitative assessment of the ex-ante energy
efficiency performance within the scope of the agreement, indicating:
a. boundaries of the energy system;
b. period and duration of the measurement of the energy consumption. The period, frequency of
measurement and number of measurements taken shall be representative and significative to
compare energy performance in the reporting period.
The energy service providers and the beneficiary shall select an adequate data collection
frequency (e.g. hourly, daily, weekly) for each energy consumption and relevant variable included
in the EnPI and the corresponding contractual energy baseline.
The data collection period and frequency should be sufficient to capture operating conditions and
provide an adequate number of data points for statistical analysis. For statistical analysis it is
critical that energy consumption and associated relevant variables have the same time intervals.
An example of statistical analysis to determine EnPI and EnPIv is reported in the informative
Annex A;
c. measured energy consumption (direct or indirect measurement);
11
---------------------- Page: 13 ----------------------
SIST EN 17669:2023
EN 17669:2022 (E)
d. energy drivers and adjustment / normalizations factors (relevant variables and static factors);
e. definition of significant EnPI and EnPIv. Values are accurate and material within the
measurement intervals used to calculate them.
In some cases, the energy baseline, EnPI and EnPIv are provided by the beneficiary or a third party
selected by the beneficiary. In these cases, it is important that:
• the energy service provider agrees to the adoption of the EnPI and EnPIv, or
• provisions are specified in the EPC (grace period, additional measurement plan, etc.) to reach, in a
defined period of time, the agreement on the provided metric and values or to a new set of indicators
and values.
Baseline for other “non-energy” related indicators are outside the scope of this standard. Nevertheless,
the same methodology can be applied.
The EPC shall identify and allocate the responsibilities to resolve:
• uncertainties in the measurement (or lack of measurements) and calculations of EnPI(s) in the
baseline, leading to inaccuracy of energy efficiency improvement evaluation;
• project risks linked to any influencing factors such as market conditions, impacts resulting from
climate change, changes of use and more widely every exogenous factor non attributable to the
energy services provider making an impact on energy consumption within the boundary of the EPIA.
NOTE 1 EN 17267 specifies the requirements and principles for the design and implementation of an energy
measurement and monitoring plan. This document can be considered as a tool to facilitate the data collection.
NOTE 2 ISO 50006 can be considered as a tool to facilitate the identification of baseline and EnPI.
7 Specification and description of the EPIA(s)
For each EPIA the following shall be specified and made transparent and verifiable for the beneficiary:
a) the reasons used to select the EPIA, unless chosen by the beneficiary;
b) the general description/category(ies) of the action:
1) measures to reduce the energy consumption (Installing building insulation, reduction of
leakage of compressed air, etc.);
2) replacement, modification or addition of equipment (Combined heat and power generation,
high efficiency boilers, variable speed motors, energy efficient lighting, connection to a
heating or cooling network, etc.);
3) more efficient operation (Building automation, logistic and layout optimization, parameter
setting, etc.);
4) improved maintenance (Maintenance planning, Internet of things, training instruction of the
operation and maintenance staff, etc.);
5) deployment of behavioral change programs (Energy efficiency awareness campaign, training,
etc.);

Introduction
Energy efficiency improvement is one of the pillars of the energy transition. It is considered as one of the
most cost-effective ways of addressing the growing demand for energy, climate change mitigation, energy
security and increased competitiveness.
Directive 2012/27/EU on energy efficiency defines Energy Performance Contracting (EPC) as
“contractual agreement between the beneficiary and the provider of an energy efficiency measure
verified and monitored during the whole term of the contract, where investment (work supply or service)
in that measure are paid for in relation to a contractually agreed level of energy efficiency improvement
or other agreed energy performance criteria, such as financial savings”.
The new energy efficiency directive (EU) 2018/2002 highlights that reaching an ambitious energy
efficiency target requires barriers to be removed to facilitate investment in energy efficiency measures.
One step in that direction is the clarification provided by Eurostat on how to record energy performance
contracts in national accounts, which removes uncertainties and facilitates the use of such contracts.
The lack of broadly accepted best practices or guidelines for EPC demands the development of a standard
defining the minimum requirements of the contractual agreement that matches the needs of:
• Policy Makers to provide tools for quality, transparency and effectiveness in Energy Performance
Improvement Actions (EPIA);
• Building owners, public or private organizations and energy service providers to adopt a contractual
framework for energy services that provides clear and transparent risk allocation and guaranteed
energy efficiency improvement and other agreed energy performance criteria;
• Financial institution and banks to have a reference contractual framework between user and energy
service provider that clearly define value generation (including multiple benefits or co-benefits of
energy efficiency) and risks allocation;
• Property valuators to help assessing the value of the asset in relation to its energy efficiency and
sustainability performance for the project lifetime.
The standard addresses the multiple domains of the contractual agreement: technical, financial, legal and
provides a common framework of methods to integrate the minimum requirements of energy efficiency
improvement
Because EPC usually has an impact on the risk allocation between the energy service provider, the
financial institution and the beneficiary of the energy efficiency improvement services, the requirements
have implication on the economic evaluation, legal, fiscal and accounting procedures for both public and
private organizations.
This document can be used in conjunction with the following
• management system standards,
• energy management standard,
• risk management standards,
• asset management standards,
• underwriting procedures of financial institutions (European Bank Authority – EBA),
• international accounting standards (International Financial Reporting Standards - IFRS);

• Eurostat statistical treatment of EPC,
• Environmental Social and Governance (ESG) requirements, or
• Action plan for Sustainable Finance.
The production of renewable energy on site does not necessarily achieve energy efficiency improvement.
Even if energy consumption across the boundary decreases, there may be no measurable improvement
in energy efficiency related to the energy use as a result of the change.
However, renewable energy production may be a component of an EPC and is therefore considered to be
in the scope of this document when delivered in combination with an EPIA.

1 Scope
This document defines the minimum requirements for an energy performance contracting (EPC). The
energy performance improvement actions (EPIAs) are meant to achieve a guaranteed level of energy
efficiency improvement and other agreed energy performance related criteria irrespective of the
quantity, use, or types of energy consumed.
This document is intended to be applied to EPIA(s) on existing assets.
The requirements are set in order to provide:
• transparency throughout the whole process that will result in the Energy Performance Contract,
• cost effectiveness in relation to the benefits generated by the energy efficiency measure,
• a quality assurance, risk mitigation and risk allocation toolkit,
• material information necessary for financial and technical calculations for both beneficiary and
energy service provider.
The document is applicable to energy service providers and beneficiaries regardless of their type, size,
complexity or geographical location.
This document may be used by financial institutions and other stakeholders of the process.
NOTE This document can be used in conjunction with Eurostat and International Accounting Standards Board
(IASB) guidance.

NOTE Additional objectives set in the EPC and that do not lead to savings directly connected to energy
efficiency savings are generally paid in relation to other criteria defined in the contractual agreement.
9
---------------------- Page: 11 ----------------------
oSIST prEN 17669:2021
prEN 17669:2021 (E)
An EPC shall include, as a minimum:
1. the EPIA(s) description,
2. the ex-ante EnPI related to the boundary of the EPIA(s),
3. the relevant variables and static factors,
4. an algorithm that correlates the EnPI(s) with the relevant variables and static factors,
5. the guaranteed energy efficiency improvement in relation to relevant variables and static factors for
the whole contract duration,
6. the methodology for measurement & verification and the reporting plan to assess (at least annually)
the energy efficiency improvement over time,
7. the value of the investment committed for the EPIA(s) implementation,
8. the responsibilities and payment allocation for the energy supply,
9. the ownership of the EPIA(s) asset(s),
10. the responsibilities and the allocation of costs for operation, maintenance and repairs for the whole
contract duration of the EPC,
11. a description of the economic, financial or other remedies and compensations (penalties) in case of
failing to achieve the annual guaranteed energy saving,

15. the contract duration,
16. in case of availability of incentives (economic, financial, fiscal, etc.) who is the beneficiary.
6 Contractual energy baseline
The contractual energy baseline is a value for a reference period that appropriately represents the range
of operating conditions ex-ante implementation of the EPIA(s). This enables changes in energy
performance to be accurately represented by comparing EnPI values for the reporting and baseline
periods.
The type of information needed to establish an energy baseline is determined by the specific purpose of
the EPIA(s), and by the effect of relevant variables on energy performance.
The EPC shall define an exhaustive, qualitative and quantitative assessment of the ex-ante energy
efficiency performance within the scope of the agreement, indicating:
• boundaries of the energy system;
10
---------------------- Page: 12 ----------------------
oSIST prEN 17669:2021
prEN 17669:2021 (E)
• period and duration of the measurement of the energy consumption. The period, frequency of
measurement and number of measurements taken shall be representative and significative to
compare energy performance in the reporting period.
The energy service providers and the beneficiary shall select an adequate data collection frequency
(e.g. hourly, daily, weekly) for each energy consumption and relevant variable included in the EnPI
and the corresponding contractual energy baseline.
In case of default of data collection, a method to assess the result shall be defined.
The data collection period and frequency should be sufficient to capture operating conditions and
provide an adequate number of data points for statistical analysis. For statistical analysis it is critical
that energy consumption and associated relevant variables have the same time intervals. An example
of statistical analysis to determine EnPI and EnPI value is reported in the informative Annex A.
• measured energy consumption (direct or indirect measurement);
• energy drivers and adjustment / normalizations factors (relevant variables and static factors”,);
• definition of significant EnPI and EnPI value. EnPI value are accurate and material within the
measurement intervals used to calculate them.
In some cases, the energy baseline, EnPI and EnPI value are provided by the beneficiary or a third party
selected by the beneficiary. In these cases, it is important that:
• the energy service provider agrees on the adoption of the EnPI and EnPI value or
• provisions are defined in the EPC (grace period, additional measurement plan, etc.) to reach, in a
defined period of time, the agreement of previous point a) on the provided metric and values or on a
new set of indicators and values.
Baseline for other “non-energy” related indicators are outside the scope of this standard. Nevertheless,
the same methodology can be applied.
The EPC shall identify and allocate the responsibilities to resolve:
• uncertainties in the measurement (or lack of measurements) and calculations of EnPI(s) of baseline,
leading to a volatility of energy efficiency improvement evaluation;
• project risks linked to undefined (uncertain, unsettled) EPIA(s) or any other influencing factors such
as market condition, climate changes, etc having impact on energy consumption within the boundary
of the EPIA.
NOTE EN 17267 specifies the requirements and principles for the design and implementation of an energy
measurement and monitoring plan. This document can be considered as a tool to facilitate the data collection.
7 Definition and description of the EPIA(s)
For each EPIA shall be defined and made transparent for the beneficiary:
i.) the reasons used to select the EPIA, unless chosen by the beneficiary;
ii.) the general description/category(ies) of the action (according with EN 15900:2009 Clause 4.2):
11

prEN 17669:2021 (E)
a) measures to reduce the energy consumption (Installing building insulation, reduction of leakage
of compressed air, etc.)
b) replacement, modification or addition of equipment (Combined heat and power generation, high
efficiency boilers, variable speed motors, energy efficient lighting, etc.);
c) more efficient operation (Building automation, logistic and layout optimization, parameter

h) expected technical lifetime;
i) beneficiary duties, obligation and needed/useful actions to be performed at the end of or after
the EPC duration (example maintenance requirements, insurance obligations, reimbursement of
the guaranties, etc.);
j) end of life disposal requirements.
8 Methodology for the evaluation of the energy efficiency improvement (ex-
post)
The methodology to evaluate the energy efficiency improvement is based on a measurement and
monitoring plan for example using ISO 50015.
The methodology shall be characterized by materiality (i), simplicity (ii), transparency (iii) and
traceablility (iv):
i.) the assessment shall undertake on measurements. The quality of data shall not be less than what
defined in paragraph 6 ii.). All meters relevant to the measurement and monitor plan are defined
(tags, position in the P&I diagram, serial number, accuracy, periodic calibration certificates, etc.);

prEN 17669:2021 (E)
ii.) the algorithm to calculate the energy efficiency improvement over a defined period shall include the
ex post energy consumption and EnPI value versus baseline considering adjustment / normalization
factors and the level of service as appropriate. All elements of the algorithm are clearly defined;
iii.) the measurement and figures used in the algorithm are available and can be audited and used
without ambiguity by any nominated third party to verify energy efficiency improvement;
iv.) the information is available over time with the use of technology and is possible to determine its
origination.

EPC scope may include other binding obligations (Clause 5) and objectives.
The methodology for the evaluation of other improvement measures shall refer to the general
requirements of materiality, simplicity, transparency and traceability of Clause 8.
The specific measurement and monitor plan has to be developed on a case by case approach and it may
include a one-time acceptance test during the commissioning of the implemented measure.
NOTE 1 As example in case of measures to reduce environmental impact (e.g.: emissions, noise) the methodology
can refer to EN ISO 14007 “Environmental management – Guidelines for determining environmental costs and
benefits”.
NOTE 2 in case of retrofitting, upgrading measures to repair and bring up to standards existing assets the
compliance test undertaken during commissioning can be accepted as evaluation of the implemented measure(s).
10 Energy service provider obligations
The energy service provider is responsible for each EPIA(s) of:
• permitting procedures;
• engineering activities in accordance with relevant laws, industry standards and best practices;
