Energijsko učinkovite storitve - Definicije in bistvene zahteve

Ta evropski standard določa definicije in minimalne zahteve za energijsko učinkovite storitve. Energijsko učinkovite storitve igrajo zelo pomembno vlogo pri nadzoru porabe energije in izboljšavi energijske učinkovitosti. Veljajo za vse sektorje. Izboljšana energijska učinkovitost se lahko doseže zlasti s povečevanjem razpoložljivosti in uporabo energijsko učinkovitih storitev. Ta standard se lahko uporabi kot referenčni dokument za ustrezne kvalifikacijske, akreditacijske in/ali certifikacijske sheme za ponudnike energijsko učinkovitih storitev, kot je navedeno v členu 8 Direktive 2006/32/ES.

Overview

EN 15900:2010 is a key European Standard developed by CEN that establishes clear definitions and minimum requirements for energy efficiency services. It aims to support energy savings and promote more efficient energy use across various sectors by providing a framework for the delivery and verification of these services. EN 15900:2010 plays an essential role in enabling service providers and customers to collaborate on improving energy performance, aligning with EU Directive 2006/32/EC on energy end-use efficiency and energy services.

This standard enhances transparency and trust in energy efficiency services by specifying procedures for service delivery, energy audits, improvement actions, and performance verification. It helps accelerate the market development for energy efficiency by defining terms, responsibilities, and best practices.

Key Topics

• Energy Efficiency Service Definition
  An energy efficiency service is a set of agreed tasks designed to achieve a quantifiable improvement in energy efficiency, potentially including guarantees on minimum performance improvement.

• General Requirements
  Services must aim at measurable energy efficiency improvements and other performance metrics such as comfort, safety, or productivity. They should be based on collected data and include energy audits, implementation of improvement actions, and monitoring.

• Energy Efficiency Improvement Actions
  These may involve:

  • Reduction of energy consumption (e.g., insulation, reducing leakage)
  • Equipment upgrades (e.g., combined heat and power, efficient lighting)
  • Enhanced operations (e.g., automation, process optimization)
  • Continuous optimization and maintenance improvements
  • Behavioral change programs (training, awareness campaigns)
  • Implementation of energy management systems (e.g., compliant with EN 16001)

• Verification and Measurement
  The standard requires documented baselines and adjustment factors to allow consistent comparisons of energy consumption before and after interventions. Verification includes measurement plans, agreed procedures, and regular reporting.

• Framework and Follow-Up
  A documented framework should define baseline energy use, planned actions, expected improvements, contractual guarantees, responsibilities, verification methods, and timelines.

---

Applications

EN 15900:2010 is applicable across multiple industries and services where control of energy consumption is critical, including:

• Industrial and Manufacturing Sectors
  Optimizing processes, integrating high-efficiency equipment, and maintaining systems for better energy performance.

• Buildings and Facilities Management
  Implementing insulation, HVAC optimization, and building automation to reduce energy waste.

• Energy Service Companies (ESCOs)
  Facilitating contractual energy savings projects with guaranteed or measured energy efficiency improvements.

• Public and Private Sectors
  Helping organizations meet regulatory requirements and sustainability goals through standardized energy efficiency services.

• Consultants and Auditors
  Providing clear methodologies for audits, baseline setting, and energy savings verification to support credible energy service offerings.

• CEN/CLC TR 16103 – Energy management and energy efficiency - Glossary of terms
  Clarifies terminology used in energy efficiency services and management.

• International Performance Measurement and Verification Protocol (IPMVP)
  Provides additional guidance on quantifying energy and water savings.

• Relevant EU Directives:

  • Directive 2006/32/EC on energy end-use efficiency and energy services
  • Directive 2002/91/EC on the energy performance of buildings
  • Directive 2004/8/EC promoting cogeneration with useful heat demand

EN 15900:2010 establishes a rigorous foundation to improve the quality, accountability, and market trust of energy efficiency services, thereby supporting Europe’s energy efficiency targets and sustainability commitments. Organizations adopting this standard benefit from clear processes for energy audits, improvement action delivery, and results verification, ensuring continuous energy performance enhancements and cost savings.

Example of an energy efficiency service provision process .8Bibliography .9 SIST EN 15900:2011

This standard may be used as a reference document for appropriate qualification, accreditation and/or certification schemes for providers of energy efficiency services, as mentioned in Article 8 of Directive 2006/32/EC. This standard is written to provide guidance to both customers and providers of energy efficiency services, as mentioned in Article 1 of Directive 2006/32/EC, and to contribute to the development of a market for energy efficiency services.
Figure 1 — Diagram illustrating a typical energy efficiency service provision process A diagram illustrating a typical energy efficiency service provision process is shown in Figure 1, where upper shapes represent "activities" and lower shapes represent "deliverables", according with Table A.1 in Annex A. The process steps may be performed by different parties although the responsibility for the energy efficiency improvement is generally taken by one single party.
The service provider(s) and the customer should strive to implement a continuous improvement in energy efficiency.
adjustment factor quantifiable parameter affecting energy consumption
EXAMPLES Weather conditions, behaviour related parameters (indoor temperature, light level), working hours, production throughput, etc. 3.2
baseline energy consumption calculated or measured over a period of time normalized by adjustment factors 3.3
energy audit systematic inspection and analysis of energy use and energy consumption of a system or organisation with the object of identifying energy flows and the potential for energy efficiency improvements NOTE "Energy audit" is the normal expression in English but can cause confusion when translated due to the word "audit" having multiple meanings. Suitable expressions can be used when translating into other languages, for example: "diagnosi" in Italian, "diagnostic" in French.
