Energy Performance of Buildings - Basic Principles for the set of EPB standards
This Technical Specification describes the basic principles to be followed in the development of standards intended to support the assessment of the energy performance of buildings using a holistic approach. The main goal is to obtain a set of EPB-standards that are a systematic, clear and comprehensive package for the benefit of professionals and government entities.
This Technical Specification gives general, qualitative guidance on the required quality, accuracy, usability and consistency of EPB-standards in order to provide a balance between:
- the accuracy and level of detail, and
- the simplicity and availability of input data.
Hidden complexities are also taken into account, such as the impact of differences in the overall legal frameworks on the national choices and national input data.
The basic principles are the basis for detailed technical rules and for a common overarching structure for the set of EPB-standards.
The basic principles for EPB-standards cover the following aspects:
- the standardization process, including collaborations and consultations;
- the application range of the standards;
- common general organisation of each standard and the national implementation;
- the overarching structure for the energy performance assessment;
- common model(s) and editorial rules for each standard;
- common quality aspects for each standard.
Energieeffizienz von Gebäuden - Grundlagen für das EPB-Normenpaket
Diese Technische Spezifikation beschreibt die Grundsätze, die bei der Entwicklung von Normen für die Bewertung der Gesamtenergieeffizienz von Gebäuden nach einem ganzheitlichen Ansatz zu befolgen sind. Das Hauptziel ist, eine Reihe von Normen zur Gesamtenergieeffizienz von Gebäuden in Form eines syste-matischen, klaren und umfassenden Pakets zu erhalten, das Fachleuten und Regierungsstellen von Nutzen ist.
Die vorliegende Technische Spezifikation enthält allgemeine qualitative Aussagen zur geforderten Qualität, Genauigkeit, Anwendbarkeit und Folgerichtigkeit von Normen zur Gesamtenergieeffizienz von Gebäuden mit dem Ziel, einen Ausgleich zu erreichen zwischen
der Genauigkeit und dem Grad der Detailliertheit und
der Einfachheit und Verfügbarkeit von Eingabedaten.
Auch versteckte Komplikationen wie z. B. die Auswirkungen von Unterschieden zwischen den allgemeinen Rechtsstrukturen auf die nationalen Wahlmöglichkeiten und nationalen Eingabedaten werden berücksichtigt.
Die Grundsätze sind der Ausgangspunkt für ausführliche technische Regeln und für eine allgemeine Struktur der Rahmennorm für die Normenreihe zur Gesamtenergieeffizienz von Gebäuden.
Die Grundsätze für Normen zur Gesamtenergieeffizienz von Gebäuden decken die folgenden Aspekte ab:
- den Normungsprozess einschließlich Zusammenarbeit und Beratung;
- den Anwendungsbereich der Normen;
- die allen diesen Normen gemeinsame allgemeine Gliederung und ihre nationale Umsetzung;
- die Rahmenstruktur für die energetische Bewertung;
- das (die) gemeinsame(n) Modell(e) und Redaktionsregeln für alle diese Normen;
- gemeinsame Qualitätsaspekte für jede Norm.

Energijske lastnosti stavb - Osnovna načela za skupino standardov EPBD
Ta tehnična specifikacija opisuje osnovna načela, ki jih je treba upoštevati pri pripravi standardov, namenjenih podpori ocenjevanja energijskih lastnosti stavb s holističnim pristopom. Glavni cilj je zagotoviti sistematsko, jasno in izčrpno skupino standardov EPB, v korist profesionalcev in vladnih organov. Ta tehnična specifikacija podaja splošna, kvalitativna navodila v zvezi z zahtevano kakovostjo, točnostjo, uporabnostjo in skladnostjo standardov EPB, da bi se zagotovilo ravnovesje med: – točnostjo in podrobnostjo ter – enostavnostjo in razpoložljivostjo vhodnih podatkov. Upoštevajo se tudi skrite kompleksnosti, kot so vpliv razlik v splošnih pravnih okvirih na nacionalne izbire in nacionalne vhodne podatke. Osnovna načela so podlaga za podrobna tehnična pravila in za skupno glavno strukturo za skupino standardov EPB. Osnovna pravila za standarde EPB zajemajo naslednje vidike: – proces standardizacije, vključno s sodelovanjem in posvetovanji; – obseg uporabe standardov; – skupno splošno organizacijo vsakega standarda in nacionalno izvajanje; – glavno strukturo za oceno energetske učinkovitosti; – skupni(-e) model(-e) in uredniška pravila za vsak standard; – splošne vidike glede kakovosti za vsak standard.

This Technical Specification (CEN/TS) was approved by CEN on 10 May 2014 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of 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 United
Kingdom.

Foreword
This document (CEN/TS 16628:2014) 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 th
