Foreword
This document (CEN/TS 16629:2014) has been prepared by Technical Committee CEN/TC 371 “Energy
Performance of Buildings Project Group”, the secretariat of which is held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association (Mandate M/480, [2]).
This document supports requirements of EU Directive 2010/31/EC on the energy performance of buildings
(EPBD). It forms part of a series of standards aimed at European harmonization of the methodology for the
calculation of the energy performance of buildings.
Directive 2010/31/EU recasting the Directive 2002/91/EC on energy performance of buildings (EPBD) [1]
promotes the improvement of the energy performance of buildings within the European Union, taking into
account all types of energy uses (heating, lighting, cooling, air conditioning, ventilation) and outdoor climatic
and local conditions, as well as indoor climate requirements and cost effectiveness (Article 1).
The Directive requires Member States to adopt measures and tools to achieve the prudent and rational use of
energy resources. In order to achieve those goals, the EPBD requires increasing energy efficiency and the
enhanced use of renewable energies in both new and existing buildings. One tool for this is the application by
Member States of minimum requirements on the energy performance of new buildings and for existing
buildings that are subject to major renovation, as well as for minimum performance requirements for the
building envelope if energy-relevant parts are replaced or retrofitted. Other tools are energy certification of
buildings, inspection of boilers and air-conditioning systems.
NOTE The use of European Standards increases the accessibility, transparency and objectivity of the energy
performance assessment in the Member States facilitating the comparison of best practices and supporting the internal
market for construction products. The use of EPB-standards for calculating energy performance, as well as for energy
performance certification and the inspection of heating systems and boilers, ventilation and air-conditioning systems will
reduce costs compared to developing different standards at national level.
The first mandate to CEN to develop a set of standards to support the EPBD (M/343) resulted in the
successful publication of several EPBD related CEN standards in 2007-2008. The second mandate to CEN
(M/480, [2]) was issued to review the Mandate M/343 as the recast of the EPBD raises the need to revisit the
standards and reformulate and add standards so that they become on the one hand unambiguous and
compatible, and on the other hand a clear and explicit overview of the choices, boundary conditions and input
data that need to be defined at national or regional level. Such national or regional choices remain necessary,
due to differences in climate, culture and building tradition, policy and legal frameworks. Consequently, the
current set of EPBD related standards had to be improved and expanded on the basis of the recast of the
EPBD. EPB-standards should be flexible enough to allow for necessary national and regional differentiation
and facilitate Member States implementation and the setting of requirements by the Member States.
The set of EBP-standards should consist of a comprehensive package of Technical Specifications and
European Standards that are manageable and user-friendly for regulators, product Technical Specification
drafters, drafters of European Technical Approval Guidelines/Common Understanding Assessment
Procedures (ETAGs/CUAPs), producers, notified bodies and users.
The set-up of a coherent set EPB-standards under Mandate M/480 was split into two phases:
— the development of (and agreement on) the underlying basic principles and detailed technical rules for
drafting EPB-standards providing a coherent modular structure and an overarching EPB-standard
following these rules and principles;
4

---------------------- Page: 6 ----------------------

SIST-TS CEN/TS 16629:2014
CEN/TS 16629:2014 (E)
— on the basis of the results of phase 1: the preparation/revision of the complete set of EPB- standards.
The basic principles and technical rules were developed to ensure the necessary overall consistency in
terminology, approach, input/output relations and formats in all EPB-standards In these rules and
specifications requirements from competent national legal authorities of EU and EFTA Member States
(aggregated by the CAP-EDMC liaison committee) were taken into account.
It is anticipated that during phase 2 additions or modifications of the overarching EPB-standard and/or basic
principles and detailed technical rules might be needed.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus,
Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany,
Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland,
Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

6.2 Coordination of EPB-standards
6.2.1 General
EPB-standards are required for technologies specified in the Technical Report accompanying FprEN 15603.
These standards have to be set up/maintained by respective competent TCs.
The modular structure defined in the overarching EPB-standard (FprEN 15603) shall be used to identify these
standards. Each individual EPB-standard may cover one module, part of it or a number of modules defined in
FprEN 15603:2014, Clause 6.
In order to maintain coherence between EPB-standards, coordination considering the use of terms, symbols,
and time steps is essential. For this, standard developers should contact CEN/TC 371 prior to publishing the
draft EPB-standard for public enquiry. CEN/TC 371 is the horizontal TC responsible for the coherence of EPB-
standards. In order to safeguard whether the terms for accepting a standard within the EPB-standard
package, checking by CEN/TC 371 is essential.
In order to safeguard the coherence between EPB-standards, coordination between the competent TC(s) and
CEN/TC 371 is required if one of the calculation procedures in the set of EPB-standards requires one of the
following:
— data that is not defined by a product standard;
— data for which no standardized measurement procedure is available;
1)
— data that is not consistent with requirements from related EU Directives .
6.2.2 Coordination with product standards
In defining calculation procedures, product data already defined in the relevant CEN/TC shall be used
whenever appropriate. Each WG shall check the availability of appropriate input data in the relevant EN
product standards.
6.2.3 Coordination between CEN and ISO
NOTE 1 See CEN/TS 16628 for the basic principles for developing EN ISO EPB standards.
Having different CEN and ISO standards would harm both CEN and ISO as well as the users of the
