Energy performance of buildings - Building management system - Part 1: Module M10-12 (ISO 52127-1: 2021)

This European Standard specifies operational activities, overall alarming, fault detection and diagnostics, reporting, monitoring, energy management functions, functional interlocks and optimizations to set and maintain energy performance of buildings.
Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in prEN ISO 52000 1:2015.
NOTE 1   In FprCEN ISO/TR 52000 2:2014 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 may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively.

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).

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.

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

optimisation,
— sequencing of multiple generators,

— 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.

— “Function 1 – setpoints”, is meant for setpoint definition and set back. This function refers to
