ISO 52127-1:2021(E)
Introduction
This document is part of a series of standards aiming at international harmonization of the methodology
for the assessment of the energy performance of buildings called “EPB set of standards”.
As part of the “EPB set of standards”, it complies with the requirements for the set of basic EPB
documents ISO 52000-1 (see Normative references), CEN/TS 16628 and CEN/TS 16629 (see References
[4] and [5]) developed under a mandate given to CEN by the European Commission and the European
Free Trade Association (Mandate M/480), and supports essential requirements of EU Directive
2010/31/EU on the energy performance of buildings (EPBD).
This document is clearly identified in the modular structure developed to ensure a transparent and
coherent EPB standard set in ISO 52000-1. BAC (building automation and control) is identified in the
modular structure as technical building system M10. However, other standards issued by ISO TC 205
deal with control accuracy, control functions and control strategies using standards communications
protocol (these last standards do not belong to the EPB standards set).
To avoid a duplication of calculation due to the BAC (avoid double impact), no calculations are done in
BAC EPB standard set, but in each underlying standard of EPB set of standards (from M1 to M9 in the
modular structure), an identifier, developed and presented in the M10 covered by ISO 52120-1, is used
where appropriate. The way of interaction is described in detail in ISO/TR 52000-2 accompanying the
over-arching standard. As a consequence, the Annex A and Annex B concept as Excel sheets with the
calculation formulas used in the EPB standards are not applicable for this document.
The main target groups of this document are all the users of the set of EPB standards (e.g. architects,
engineers, regulators).
Further target groups are parties wanting to motivate their assumptions by classifying the building
energy performance for a dedicated building stock.
[3]
More information is provided in ISO/TR 52127-2 , the Technical Report accompanying this document.
Table 1 shows the relative position of this document within the set of EPB standards in the context of
the modular structure as set out in ISO 52000-1.
NOTE 1 In ISO/TR 52000-2 the same table can be found, with, for each module, the numbers of the relevant
EPB standards and accompanying Technical Reports that are published or in preparation.
NOTE 2 The modules represent EPB standards, although one EPB standard can cover more than one module
and one module can be covered by more than one EPB standard, for instance a simplified and a detailed method
respectively.

— building energy management and load management with regard to the utilisation of local renewable
energy and local energy production,
— heat recovery and heat shifting,
— smart grid interactions, demand side management, and peak shaving.
Calculation is, in general, independent from the time step chosen but is according to the time step of
the input.
It is important to be aware that the technical building management (TBM) functions not fully automated
will have an impact on energy performance of the building only if they are not only installed but actively
used, i.e. that actions are taken if monitoring results ask for it.
5.2 General description of the method(s)
This document covers several functions of the application of the building management system. These
functions shall be taken from ISO 52120-1. Each function is represented by at least one calculation method.

This document covers six of the functions described in ISO 52120-1:— , Table 4. This list of capabilities
of controls and BMS functions is not exhaustive. Energy efficiency performance of building depends
on the choice of control and BMS functions related to expected performance (following methodology
described in ISO 52000-1), their implementation, commissioning and exploitation. The functions are as
follows.

Introduction
This standard is part of a series of standards aiming at international harmonization of the methodology
for the assessment of the energy performance of buildings, called “EPB set of standards”.
As part of the “EPB set of standards” it complies with the requirements for the set of basic EPB
documents EN ISO 52000-1:2017 (see Normative references), CEN/TS 16628 and CEN/TS 16629 (see
bibliography [2] and [3]) developed under a mandate given to CEN by the European Commission and
the European Free Trade Association (Mandate M/480), and supports essential requirements of EU
Directive 2010/31/EU on the energy performance of buildings (EPBD).
This standard is clearly identified in the modular structure developed to ensure a transparent and
coherent EPB standard set in iso 52000-1. BAC (Building Automation and Control) is identified in the
modular structure as Technical Building System M10. However, other standards issued by ISO TC 205
deal with control accuracy, control functions and control strategies using standards communications
protocol (these last standards do not belong to the EPB standards set).
To avoid a duplication of calculation due to the BAC (avoid double impact), no calculation are done
in BAC EPB standard set, but in each underlying standard of EPB set of standards (from M1 to M9 in
the Modular Structure), an IDENTIFIER developed and present in the M10 covered by ISO 52120-1
is used where appropriate. These way of interaction is described in detailed in the Technical Report
(ISO/TR 52000-2:2017) accompanying the over-arching standard. As consequence, the Annex A and
Annex B concept as EXCEL sheet with the calculation formulas used in the EPB standards are not
applicable for this standard.
The main target groups of this standard are all the users of the set of EPB standards (e.g. architects,
engineers, regulators).
Further target groups are parties wanting to motivate their assumptions by classifying the building
energy performance for a dedicated building stock.

5 Description of the methods
5.1 Output of the method
This method covers the calculation of the building operation data that could be influenced and
optimized by a building management system. Those data are mainly related to:
— setpoint including set back,
— operation times of heating, ventilation, cooling and lighting systems including start-stop-
optimization,
— sequencing of multiple generators,
— building energy management and load management with regard to the utilization of local renewable
energy and local energy production,
— heat recovery and heat shifting,
— smart grid interactions, demand side management, and peak shaving.
Calculation is in general independent from the time step chosen but is according to the time-step of
the input.
It is important to be aware that the TBM functions not fully automated will have an impact on energy
performance of the building only in case if they are not only installed but actively used, i.e. that actions
are taken if monitoring results ask for it.
5.2 General description of the method(s)
This standard covers several functions of the application of the Building management system. Each
function is represented by at least one calculation method.
This standard covers 6 of the functions described in ISO 52120-1, table 4. This list of capabilities of
controls and BMS functions is not exhaustive. Energy efficiency performance of building depends of the
choice of control and BMS functions related to expected performance (following methodology described
in ISO 52000-1), their implementation, commissioning and exploitation. The functions are as follows:
— “Function 1 – set-points”, is meant for set-point definition and set back. This function refers to
function 7.1 in ISO 52120-1, table 4.
— “Function 2 – run-time” is intended for estimating run-times. This function refers to function 7.2 in
ISO 52120-1, table 4.
— “Function 3 – sequencing of generators” is intended for estimating the sequential arrangement of
different generators. This function refers to function 1.9 in ISO 52120-1, table 4.
— “Function 4 – local energy production and renewable energies” is intended for managing local
renewable energy sources and other local energy productions as CHP. This function refers to
function 7.5 in ISO 52120-1, table 4.
