Energy performance of buildings - Energy requirements for lighting - Part 1: Specifications, Module M9

This standard specifies the methodology for evaluating the energy performance of lighting systems for providing general illumination in residential and non-residential buildings and for calculating or measuring the amount of energy required or used for lighting in buildings. The method may be applied to new, existing or refurbished buildings. It also provides a methodology (LENI) as the measure of the energy efficiency of the lighting installations in buildings.
This standard does not cover lighting requirements, the design of lighting systems, the planning of lighting installations, the characteristics of lighting equipment (lamps, control gear and luminaires) and systems used for display lighting, desk lighting or luminaires built into furniture. This standard does not provide any procedure for the dynamic simulation of lighting scene setting.
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 EN ISO 52000-1.
NOTE   In CEN 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.
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. See also Clause 2.

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 “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 standard a normative template is given in Annex A to specify these choices.

Informative default choices are provided in Annex B.

The main target groups of this standard are all the users of the set of EPB standards (e.g. architects,

engineers, regulators).

Use by or for regulators: In case the standard 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 this Annex A) can be made available

as national annex or as separate (e.g. legal) document (national data sheet).
NOTE So in this case:
— the regulators will specify the choices;

— the individual user will apply the standard to assess the energy performance of a building, and thereby use

the choices made by the regulators.

Topics addressed in this standard 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 standard. 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 the national annex (e.g. NA) refers to this

text;

— 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 standard (CEN/TR 15193-2

[5]).

CEN/TC 169 deals with light and lighting and the subjects covered by committee are:

— Lighting criteria for indoor and outdoor activities;
— Photometry of lighting systems;
---------------------- Page: 8 ----------------------
SIST EN 15193-1:2017+A1:2021
EN 15193-1:2017+A1:2021 (E)
— Lighting terminology;
— Energy efficiency of lighting systems.

This standard specifies three methods for evaluating the energy performance of lighting systems.

It is of paramount importance that correct lighting is provided in buildings. The convention and

procedures in this standard assumes that the designed and installed lighting scheme conforms to good

lighting practices. For new and refurbished installations in the non-residential building sector the

design of the lighting system should conform to the requirements in the lighting applications standards

EN 12464-1 for indoor workplaces, EN 12193 for sports buildings and EN 1838 for emergency escape

lighting. For residential buildings the lighting system should be designed to fulfil the needs of the rooms

in the buildings. Guidance on the requirements is provided in the supporting Technical Report

CEN/TR 15193-2 [5]).

This standard also assumes that the buildings can have access to daylight to provide all or some of the

illumination required in the rooms and that in addition there will be an adequate amount of electric

lighting installed to provide the required illumination in the absence of daylight or with a reduced

daylight contribution.

This standard defines the methods for estimating or measuring the amount of energy required or used

for lighting in buildings. The method of separate metering of the energy used for lighting will also give

regular feedback on the effectiveness of the lighting control.

The methodology of energy estimation not only provides values for the Lighting Energy Numeric

Indicator (LENI) but it will also provide input for the heating and cooling load estimations for the

combined total energy performance of building indicator.

Figure 1 gives an overview of the methodology and the flow of the processes involved.

NOTE The dotted line in Figure 1 linking preliminary annual LENI to the comprehensive lighting design

indicates the requirement to follow-up the budget calculation with a comprehensive calculation during the

detailed lighting design process.

This standard was developed during the first EPBD mandate and the first edition was published in

2007.

The revision for inclusion in the second mandate package was performed during 2013-2016.

The most important changes are:
— extension of calculation methods,
— inclusion of lighting for residential buildings,
— substantial editorial changes.

1 Scope

This standard specifies the methodology for evaluating the energy performance of lighting systems for

providing general illumination in residential and non-residential buildings and for calculating or

measuring the amount of energy required or used for lighting in buildings. The method may be applied

to new, existing or refurbished buildings. It also provides a methodology (LENI) as the measure of the

energy efficiency of the lighting installations in buildings.

This standard does not cover lighting requirements, the design of lighting systems, the planning of

lighting installations, the characteristics of lighting equipment (lamps, control gear and luminaires) and

systems used for display lighting, desk lighting or luminaires built into furniture. This standard does not

provide any procedure for the dynamic simulation of lighting scene setting
