European foreword

This document (prEN 17669:2021) has been prepared by Technical Committee CEN/CLC/JTC 14 “Energy

management and energy efficiency in the framework of energy transition”, the secretariat of which is held

by UNI.
This document is currently submitted to the CEN Enquiry.

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);

---------------------- Page: 6 ----------------------
oSIST prEN 17669:2021
prEN 17669:2021 (E)
• 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.

• deliver material information for the due diligence and underwriting procedures of financial

institutions to support financeability;

• provide material information for statistical treatment and financial accounting;

• define reporting guidelines for financial, non financial, sustainability disclosure and property

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 EPC shall be demonstrated through measurement

and verification.
5 EPC’s Energy Targets

The EPC shall define 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 defined in the baseline. The

change of EnPI value can be expressed as absolute values or percentage.

The energy targets shall include the level of service and/or comfort to be achieved.

The EPC can also include other objectives such as:
• environmental: CO or other emissions reduction objectives;
• costs reduction;
• safety measures improvement;
• improvement of earthquake building code.

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 level of energy

efficiency improvement or other agreed energy performance criterion or financial savings.

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.

---------------------- 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,

12. a description of economic, financial or other compensation bonuses in case of savings in excess to

the annual guaranteed energy saving,

13. the definition and beneficiary of any kind and form of applicable incentives (economic, financial,

fiscal, etc.),

14. the identification of EPIA’s implementation risks and their mitigation and allocation,

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;
---------------------- 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):

---------------------- Page: 13 ----------------------
oSIST prEN 17669:2021
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

setting, etc.);

d) improved maintenance (Maintenance planning, Internet of things, training instruction of the

operation and maintenance staff, etc.)

e) deployment of behavioral change programs (Energy efficiency awareness campaign, training,

etc.).

Note: general description refers to the kind of EPIAs that is going to be implemented.

iii.) the specific description of the action:
a) technical specification and energy performance of the asset(s);
b) number of units;
c) maintenance requirements;

d) expected interaction with existing equipment and use of additional resources (water, land,

emissions, etc);
e) expected energy efficiency improvement;

f) other expected benefits or improvement (qualitative and measurable benefits may include

environmental benefits, waste reduction, circular economy, comfort)
g) permitting requirements;
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.);

---------------------- Page: 14 ----------------------
oSIST prEN 17669:2021
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.

The methodology may refer to applicable standard to the specific EPIA implementation such as

ISO 50015, ISO 50047, EVO IMPV, or other publicly available standards.
9 Methodology for the evaluation of other improvement measures (ex post)
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;

NOTE 1 In case of behavioural changes EPIA, the engineering activities refer to the implementation plan

(communication plan, training program, etc.).
