Introduction

Light allows us to see visual tasks and their surrounding area effectively and efficiently in comfort,

safety and security, in all conditions. Furthermore light affects our circadian rhythms, mood, improves

our performance and well-being. A good lighting design will deliver light where and when it is required

at the right level, direction and quality over the required time.

Illumination can be provided by daylight, electric light or by a combination of these two sources

through a well-designed, installed and operated lighting system.

The lighting system design process is an iterative process and this technical specification describes the

key design considerations in the process for a good quality, energy efficient and effective lighting

system for major projects in the tertiary lighting sectors listed in the scope. The final designed lighting

system should provide efficient and effective good quality lighting for the user needs. Good lighting

quality improves quality of life, human health, productivity, comfort and function. The design should

include safety/emergency lighting based on risk assessment or legislation identified during

consultation. Elements of this design process can also be used for smaller lighting schemes.

The full lighting system design process will support implementation of regulatory measures and the

development of verification requirements. In this way it will ensure that the anticipated energy savings

will be met without jeopardising the required lighting conditions.

The lighting system design process is a tool that can be regulated by legislation.

Lighting systems are often subject to input from other design disciplines and shall respect and take into

account the intrinsic requirements and tolerances of other components.
The complete design of a lighting system typically consists of:
— the lighting system design;

— design of the electrical system and structures of the system, as regulated by the legislation in force

and by the applicable International, European and National standards.

This document sets out the general frame of a lighting system design process that can be applied to

lighting of any projects including smart buildings.

4 Design approach
A well-designed lighting system brings together:
— the requirements of the visual task(s), carried out by the users of the space;
— the requirements of people, moving through the space;
— the requirements for escape lighting where needed;

— the acceptance of constraints imposed by the client or physical nature of the space;

— the requirements for the environment and sustainability;
— the opportunities provided by the space, for example:
— possibilities to ease and simplify installation and maintenance;
— availability of daylight;
— occupancy patterns;
— surface finishes;
— issues of form, composition and style;
— consideration of different options for the space;

— the requirements of the human concerning non-visual, emotional and biological aspects of light.

By combining the best choice of luminaires and available daylight with the best control strategy to

match the space and tasks, and by providing flexibility in the lighting scheme to allow the lighting to be

varied according to user requirements, energy savings may be made whilst providing a safe and

comfortable environment. In buildings the designer has to consider the options for daylight supply

through suitably located windows and/or rooflights and appropriate shading to avoid glare and

overheating.

A well-designed lighting system should be simple to use and maintain. If the users of the space are well

trained in its operation and use and simple maintenance routines set out then the potential energy

savings through the life of the installation will be realized.
---------------------- Page: 12 ----------------------
SIST-TS CEN/TS 17165:2019
CEN/TS 17165:2018 (E)

For this to happen it is necessary to determine energy efficiency based upon energy usage throughout a

year (LENI according to EN 15193-1 and AECI according to EN 13201-5) as opposed to installed load or

equivalent, as installed load does not correctly account for dimming and switching in response to

available daylight, occupant needs and occupancy patterns.
A well-designed lighting system should include:

— lighting of the task and surroundings to ensure efficient and effective performance;

— lighting of the space to ensure a comfortable and pleasant environment to work, stay and live in;

— lighting of the space to ensure safety, health and well-being at all material times i.e. during normal

occupancy or emergency conditions;

— minimizing lighting energy requirements through life. The energy requirements should be

minimized through prudent design, installation, operation and maintenance;

— control of the life-cycle-costs of the lighting system. Minimizing capital and operational costs

through cost effective design, equipment selection, installation, operation and maintenance

procedures.

In all cases European standards shall be used where they exist as a basis to allow verification of claims.

5 Requirements for design

The lighting system should be designed by the lighting system designer usually appointed by the client

and/or their representative. The designed lighting system will:

— fulfil the clients brief, unless this is varied with their agreement during design development;

— conform to the criteria set by the relevant lighting application standards;

— shall consider both the task(s) being performed and the age and ability profile(s) of expected

occupants and conform to the lighting criteria set for surrounding areas around tasks;

— meet all legal requirements including the selection of approved products fit for purpose;

— shall take into account the risks associated with health and safety during installation and

installation should be according to EU Directive 92/57/EEC;

— the designer shall cooperate with other designers to ensure coordination of harmonized design and

agree compromises of product selections and locations in the desired installed places;

— the designer shall include recommendation for a maintenance regime based on the criteria used to

select the maintenance factors used when designing the lighting systems;

— the designer should ensure that any necessary variation to the initial design do not adversely or

materially affect the quality of the lighting design and should agree to these changes or seek a

deviation document listing the changes.

In addition the designer shall consider how to fulfil these requirements in a manner that provides a

comfortable and appropriate visual environment.

The client brief can contain other instructions for the project completion such as deliverables,

verification processes and approval criteria. It is recommended, that in some cases the maintenance

---------------------- Page: 13 ----------------------
SIST-TS CEN/TS 17165:2019
CEN/TS 17165:2018 (E)

factor is defined in cooperation with persons responsible for maintenance and cleaning according to

their requirements.

The lighting system designer can also agree a brief with the client to set out the requirements of the

users of the space, time scales, etc. as needed.

The criteria for the required illumination for places in the tertiary lighting sector are well defined in the

various European lighting application standards. A list of relevant lighting standards is given in

Annex C. In lighting design the latest published versions shall be used.

The lighting system designer shall work to the standard of good practice. The designer should ensure

that the right lighting is provided by the lighting system that is energy efficient, economic and fit for

purpose. For energy efficient lighting system the luminaires should be combined with lighting controls

to form an integral solution. Such solutions will allow the delivered light output, particularly in

multipurpose rooms or areas, to be configured to the task or environment requirements.

The lighting design of a multi-disciplinary project should be carried out at the same time as the design

of the project as a whole.
6 Design process

The complete lighting system design is an iterative process in which inputs may change such as:

— the client’s brief;
— the feasibility study and concept options;
— design assumptions;

— data on the physical project location including any specific design constraints;

— the selection of the lighting criteria;

— lighting solution options including the provision of emergency lighting where required.

The project completion documentation and recorded working files should include:
— project documents;
— design assumptions (of the lighting system designer);
— the summary statement of the concept philosophy;
— lighting scheme drawings;

— all necessary information of the specified products of the lighting system (luminaires, lamps,

sensors, controls and performance data, etc.);
— lighting/energy/economic calculations in accordance with relevant standards;
— instructions for installation, commissioning, operation and maintenance.

An example of a comprehensive design process and accompanied listing of documentation for indoor

work place lighting is provided in Annex A. For other sectors a similar set of steps and documentation to

the model listing of lighting design documentation shown in Annex A can be produced.

---------------------- Page: 14 ----------------------
SIST-TS CEN/TS 17165:2019
CEN/TS 17165:2018 (E)

The design assumptions whilst treated as an input into the system design shall also be documented as

an output if they are defined by the lighting system designer. Some information can be provided by the

product supplier and the installing contractor.
The completion documents shall form the Product of the lighting system design.
Figure 1 — Lighting system design process and documentation

In general the client defines the project content and provides architectural drawings and the type of

working conditions of the site and facilities. The designer should identify the constraints such as local

regulations, health and occupational legislations and fixed items. For refurbishment projects the

information may be dated so the lighting system designer may also have to make site surveys and

prepare initial site drawings.

The project may consist of a single element such as an open plan office or may be a building complex

having many diverse activity areas such as found in a hospital. In the execution of the lighting system

design for the project the lighting designer can deal with each element separately and can sum up the

solutions and the energy requirements of the elements of the project and conclude the design with the

production of a comprehensive project information document as indicated in Figure 1.
