European foreword
This document (CEN/TR 16798-2:2019) has been prepared by Technical Committee CEN/TC 156
“Ventilation for buildings”, the secretariat of which is held by BSI.
Attention is drawn to the possibility that some of the elements of this document may be the
subject of patent rights. CEN shall not be held responsible for identifying any or all such patent
rights.
This document is part of the set of standards and accompanying Technical Reports on the energy
performance of buildings and has been prepared under the Mandate M 480 given to CEN by the
European Commission and the European Free Trade Association,
see Bibliographical Reference [35]).
Directive 2010/31/EU recasting the Directive 2002/91/EC on energy performance of buildings
(EPBD, [36]) 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.
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 CEN EPBD standards (M/343, [34]), to support the
first edition of the EPBD ([33]) resulted in the successful publication of all EPBD related CEN
standards in 2007-2008.
The Mandate M/480 was issued to review the Mandate M/343 as the recast of the EPBD raised
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 set of CEN-EPBD standards
published in 2007-2008 had to be improved and expanded on the basis of the recast of the EPBD.
The EPB standards are flexible enough to allow for necessary national and regional differentiation
and facilitate Member States implementation and the setting of requirements by the Member
States.
Further target groups are users of the voluntary common European Union certification scheme
for the energy performance of non-residential buildings (EPBD art.11.9) and any other regional

(e.g. Pan European) parties wanting to motivate their assumptions by classifying the building
energy performance for a dedicated building stock.
For the convenience of Standards users CEN/TC 156, together with responsible Working Group
Conveners, have prepared a simple table below relating, where appropriate, the relationship
between the ‘EPBD’ and ‘recast EPBD’ standard numbers prepared by Technical Committee

Introduction
This document is a guide to EN 16798-1 and can help the user in application of the standard and
give additional background information. Besides this document describes and recommends
additional topics related to the evaluation of the indoor environmental quality and new
possibilities to improve the indoor environmental quality and reduce energy use of buildings like
personalized systems, air cleaning technologies, consideration of adapted persons, etc.
This document explains how design criteria can be established and used for dimensioning of
systems. It explains how to establish and define the main parameters to be used as input for
building energy calculation and long term evaluation of the indoor environment. This document
also describes how gas phase air cleaning in the future can improve the indoor air quality and
partly substitute for outside air. Finally it will identify parameters to be used for monitoring and
displaying of the indoor environment. Different categories of criteria can be used depending on
type of building, type of occupants, type of climate and national differences. The report explains
how these different categories of indoor environment can be individually selected as national
criteria, be used in project agreement for design criteria and for displaying the yearly building
performance in relation to indoor environmental quality. The designer can also define other
categories using the principles from EN 16798-1 and this document.

European foreword
This document (FprCEN/TR 16798-2:2016) has been prepared by Technical Committee
CEN/TC 156 “Ventilation for buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the Vote on TR.
This document has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association.
This document is part of the set of standards and accompanying Technical Reports on the
energy performance of buildings and has been prepared under the Mandate M 480 given to CEN
by the European Commission and the European Free Trade Association,
see Bibliographical Reference [35]).
Directive 2010/31/EU recasting the Directive 2002/91/EC on energy performance of buildings
(EPBD, [36]) 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.
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 CEN EPBD standards (M/343, [34]), to support the
first edition of the EPBD ([33]) resulted in the successful publication of all EPBD related CEN
standards in 2007-2008.
The Mandate M/480 was issued to review the Mandate M/343 as the recast of the EPBD raised
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 set of CEN-EPBD
standards published in 2007-2008 had to be improved and expanded on the basis of the recast
of the EPBD.
The EPB standards are flexible enough to allow for necessary national and regional
differentiation and facilitate Member States implementation and the setting of requirements by
the Member States.

Further target groups are users of the voluntary common European Union certification scheme
for the energy performance of non-residential buildings (EPBD art.11.9) and any other regional
(e.g. Pan European) parties wanting to motivate their assumptions by classifying the building
energy performance for a dedicated building stock.
For the convenience of Standards users CEN/TC 156, together with responsible Working Group
Conveners, have prepared a simple table below relating, where appropriate, the relationship
between the ‘EPBD’ and ‘recast EPBD’ standard numbers prepared by Technical Committee
CEN/TC 156 “Ventilation for buildings”.
