Energy performance of buildings - Sensible and latent heat loads and internal temperatures - Part 1: Generic calculation procedures (ISO 52017-1:2017)
This new international standard will, in two parts, integrate EN 15265, EN 15255, EN-ISO 13791 and EN-ISO 13792.
Depending on the development, the split between part 1 and part 3 will be between a detailed method(s) (part 1) and simple method(s) (part 3).
This standard will contain a consistent and integrated set of requirements and additional descriptions of the thermal balance model for the hourly calculation of the energy needs for heating and cooling, the heating and cooling loads and indoor temperature in a thermal zone of a building. It will be directly usable by ISO 52016-1 for the calculation of the energy needs and by other EPB standards (e.g. from CEN/TC 156) dealing with needs, loads or indoor (e.g. summer) temperature calculations.
Energieeffiziens von Gebäuden - Fühlbare und latente Wärmelasten und Innentemperaturen - Teil 1: Allgemeine Berechnungsverfahren (ISO 52017-1:2017)
Dieses Dokument legt die allgemeinen Annahmen, Randbedingungen und Gleichungen für die Berechnung in stündlichen oder noch kürzeren Abständen der Innentemperaturen (Luft- und operative Temperatur) und/oder der Heiz- und Kühllast sowie der Be- und Entfeuchtungslast zur Aufrechterhaltung eines spezifischen Sollwerts (Temperatur, Feuchte) in einer einzelnen Gebäudezone fest. In diesem Dokument werden keine konkreten numerischen Verfahren vorgeschrieben.
Spezielle Berechnungsverfahren ausgehend von den allgemeinen Berechnungsverfahren in diesem Dokument sind in ISO 52016-1 angegeben. Die konkreten Vereinfachungen, Annahmen und Randbedingungen aus ISO 52016-1 sind auf die jeweiligen Anwendungsgebiete wie den Energiebedarf zum Heizen und Kühlen sowie zum Be- und Entfeuchten, die stündliche Innentemperatur, die konstruktionsmäßige Heiz-, Kühl-, Befeuchtungs- und Entfeuchtungslast zugeschnitten.
Performance énergétique des bâtiments - Charges thermiques latentes et sensibles et températures intérieures - Partie 1: Méthodes de calcul génériques (ISO 52017-1:2017)
L'ISO 52017-1:2017 spécifie les hypothèses, conditions aux limites et équations générales pour le calcul, en régime transitoire horaire ou subhoraire, des températures intérieures (de l'air et opérative) et/ou des charges calorifique, frigorifique et d'humidification et de déshumidification pour maintenir un point de consigne spécifique (température, humidité) au sein d'une zone de bâtiment unique. L'ISO 52017-1:2017 n'impose aucune technique numérique particulière.
Des méthodes de calcul spécifiques basées sur les méthodes de calcul génériques de l'ISO 52017-1:2017 sont données dans l'ISO 52016‑1. Les simplifications, hypothèses et conditions aux limites spécifiques de l'ISO 52016‑1 sont adaptées aux domaines d'application respectifs, tels que les besoins énergétiques pour le chauffage, le refroidissement et l'humidification et la déshumidification, la température intérieure horaire, et les charges calorifique, frigorifique et d'humidification et de déshumidification nominales.
NOTE Le Tableau 1 de l'Introduction indique la position relative de l'ISO 52017-1:2017 dans la série de normes PEB dans le contexte de la structure modulaire définie dans l'ISO 52000‑1.
Energetska učinkovitost stavb - Zaznavne in latentne toplotne obremenitve ter notranje temperature - 1. del: Splošni računski postopki (ISO 52017-1:2017)
Ta novi mednarodni standard bo v dveh delih integriral standarde EN 15265, EN 15255, EN-ISO 13791 in EN-ISO 13792. Odvisno od razvoja se bo razdelitev med deloma 1 in 3 odražala v razdelitvi med podrobno opisanimi metodami (del 1) in preprostimi metodami (del 3). Ta standard bo vseboval dosleden in integriran nabor zahtev ter dodatnih opisov modela toplotnega ravnovesja za urni izračun potrebne energije za ogrevanje in hlajenje, ogrevalne in hladilne obremenitve ter notranje temperature v toplotnem območju stavbe. Ta standard bo neposredno uporabljen v okviru standarda ISO 52016-1 za izračun potrebne energije in v okviru drugih standardov EPB (npr. iz CEN/TC 156), ki obravnavajo izračune potreb, obremenitev ali notranjih temperatur (npr. poleti).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

Introduction
This document is part of a series aimed at the international harmonization of the methodology for
assessing the energy performance of buildings. Throughout, this series is referred to as a “set of EPB
standards”.
All EPB standards follow specific rules to ensure overall consistency, unambiguity and transparency.
All EPB standards provide a certain flexibility with regard to the methods, the required input data and
references to other EPB standards, by the introduction of a normative template in Annex A and Annex B
with informative default choices.
For the correct use of this document, a normative template is given in Annex A to specify these choices.
Informative default choices are provided in Annex B.
The main target groups for this document are architects, engineers and regulators.
Use by or for regulators: In case the document is used in the context of national or regional legal
requirements, mandatory choices may be given at national or regional level for such specific
applications. These choices (either the informative default choices from Annex B or choices adapted to
national/regional needs, but in any case following the template of Annex A) can be made available as
national annex or as separate (e.g. legal) document (national data sheet).
NOTE 1 So in this case:
— the regulators will specify the choices;
— the individual user will apply the document to assess the energy performance of a building, and thereby use
the choices made by the regulators.
Topics addressed in this document can be subject to public regulation. Public regulation on the same
topics can override the default values in Annex B. Public regulation on the same topics can even, for
certain applications, override the use of this document. Legal requirements and choices are in general
not published in standards but in legal documents. In order to avoid double publications and difficult
updating of double documents, a national annex may refer to the legal texts where national choices
have been made by public authorities. Different national annexes or national data sheets are possible,
for different applications.
It is expected, if the default values, choices and references to other EPB standards in Annex B are not
followed due to national regulations, policy or traditions, that:
— national or regional authorities prepare data sheets containing the choices and national or regional
values, according to the model in Annex A. In this case a national annex (e.g. NA) is recommended,
containing a reference to these data sheets;
— or, by default, the national standards body will consider the possibility to add or include a national
annex in agreement with the template of Annex A, in accordance to the legal documents that give
national or regional values and choices.
Further target groups are parties wanting to motivate their assumptions by classifying the building
energy performance for a dedicated building stock.
More information is provided in the Technical Report accompanying this document (ISO/TR 52016-
[3]
2 ) accompanying this document.
The subset of EPB standards prepared under the responsibility of ISO/TC 163/SC 2 cover inter alia:
— calculation procedures on the overall energy use and energy performance of buildings;
— calculation procedures on the internal temperature in buildings (e.g. in case of no space heating or
cooling);

---------------------- Page: 11 ----------------------
SIST EN ISO 52017-1:2017
ISO 52017-1:2017(E)
— indicators for partial EPB requirements related to thermal energy balance and fabric features;
— calculation methods covering the performance and thermal, hygrothermal, solar and visual
characteristics of specific parts of the building and specific building elements and components, such
as opaque envelope elements, ground floor, windows and facades.
ISO/TC 163/SC 2 cooperates with other TC’s for the details on, e.g. appliances, technical building
systems and indoor environment.
This document is intended for use by specialists to develop methods for the hourly or subhourly
calculation of the internal temperatures and/or the heating, cooling and/or the humidification loads of
a thermal zone in a building.
Examples of application of such methods includes the following:
a) assessing the risk of internal overheating;
b) optimizing aspects of building design (building thermal mass, solar protection, ventilation rate,
etc.) to provide thermal comfort conditions;
c) assessing whether a building requires mechanical cooling;
d) assessing the energy needs for heating and cooling and for humidification and dehumidification;
e) assessing the sensible heating and cooling and humidification and dehumidification loads under
system design conditions.
Criteria for building performance are not included. They can be considered at national level. This
document can also be used as a reference to develop more simplified methods for the above and similar
applications.
Specific calculation procedures based on the generic calculation procedures of this document are given
in ISO 52016-1. The specific simplifications, assumptions and boundary conditions in ISO 52016-1 are
tailored to the respective application areas.
The main differences compared to ISO 13791 are the following:
— assumptions or procedures that are not relevant for the generic calculation procedures have been
moved to the standard with specific application and combined with other specific assumptions and
procedures, for example, specification of the convective heat transfer coefficients;
— the calculation of the operative temperature is added. The solution techniques for the calculation of
the operative temperature are not provided in this document, but left up to the specific application
standards (e.g. ISO 52016-1);
— the heat flow rates representing the sensible heating and cooling loads and the humidification and
dehumidification loads to hold a specific (temperature, moisture) set point are added to the formulae.
This widens the application range of the generic calculation procedures without adding complexity.
The solution techniques for the calculation of these loads are not provided in this standard, but
left up to the specific application standards (e.g. ISO 52016-1), because this is highly application
dependent;
— the validation cases have been removed, because there is no need to validate the implementation of
the generic calculation method itself. Conformance criteria and deviation allowances highly depend
[1]
on the application area. Moreover, the reference results of the main validation cases of ISO 13791
were questioned and could not be reproduced. Instead, the “BESTEST” test suite, standardized
[9]
as ANSI/ASHRAE 140 , comprises a number of test cases that are appropriate for (optional)
validation of the calculation methods described in this document. The relevant subset of BESTEST
cases is similar to the test cases of ISO 13791. The most relevant BESTEST cases have been adopted
in ISO 52016-1 for verification of the specific calculation procedures of that standard.
