Office work is uncommonly
varied. Communicating with
your team, advising customers,
reading documents, writing
bids on your PC or by hand on
paper each of these activities
places different requirements
on room lighting. Trend-settinglighting solutions focus on the
diversity of activities and the
corresponding specific visual
tasks. Criteria such as reducing
glare and reflections, shadow,
detail and brightness distribution
play just as important a role as
fostering a lively atmosphere
and cutting operating and main-
tenance costs. A wide variety
of needs can be encountered in
a single building or even on a
single storey. Concepts that aregeared towards needs focus light
on individual areas and, hence,
particular visual tasks. The TASK
AREA concept goes one step
further. It exploits the freedom
given within the latest lighting
design recommendations in
such a way that vertically illumi-
nated planes are considered in
addition to traditionally used
horizontal ones, while also inclu-
ding aspects of dynamism, utili-
sing intelligent lighting controls.According to Zumtobel Staf fs
TASK AREA concept, the room,
luminaire and lighting manage-
ment system are seen as an
integrated whole. If buildings are
planned in a holistic way and
planning to requirements is
carried out in detail, there is
every likelihood that this will
result in lighting installations
related to task areas and their
associated visual tasks, also
taking factors such as con-venience, flexibility, economic
efficiency and creative design
into account.

Trend-setting lighting technology
must aim to create opt imum
working conditions on the one
hand and visual experienceson the other hand in order to
make staf f members feel good
in thei r working envi ronment.
The Licht und Mensch [Light and
People] study by the German Insti-
tute for Applied Lighting Engineering
(Deutsches Institut fr Angewandte
Lichttechnik [DIAL]) confirms the
considerable potential offered by
multidimensional lighting to improve
working and living conditions.
More convenience
The focusing of light provides
creative and financial freedom
to make investments in conve-
nience and dynamism. The right
light for specific visual tasks is
but one of the many aspects
involved in optimum lighting
solutions. Vertical lighting and
accents in the room enhance
users sense of well-being.
Setting goals,meeting requirements
Designing a lighting system
according to the areas in which
visual tasks are performed
opens up additional flexibility.
The more precisely a TASK
AREA can be defined, the
more accurately the amount
and quality of the lighting
can be adjusted. This also
provides greater flexibility for
implementing outstanding
lighting solutions.
More quality
TASK AREA concepts are based
on specific lighting tasks. The
right quantity of light, in the
optimum quality, is provided at
the visual task area. Uniformity,
reduction of glare and reflec-
tions, contrast rendition and
shadow detail are adjusted to
the respective task. The lighting
is not matched just to the room,
but to what users need.
Room-related lighting concepts are
based neither on task areas nor on
different visual tasks. The lighting is
designed for the most demanding
task to be performed in the room.
The position of the workstation is
not defined; an accordingly high
lighting quality is provided for the
entire room.

Optimum energy efficiency
There is huge potential for opti-
misation, especially in spacious
buildings. The more the lighting
is focused on the TASK AREA,
the more significantly the mean
illuminance level, and thus
energy costs for the visual task
areas, are reduced.

Focusing of light opens up new hori-
zons. It provides freedom to light
surrounding areas to achieve diver-
sity. Vertically lit surfaces make a
room more open and welcoming,
dynamic changes in colour enhance
visual quality.
TASK AREA concepts focus the
lighting onto individual visual task
areas. Precise definition of visual
tasks enables accurate realisation of
lighting quality according to specific,
locally restricted requirements.

The perfect conceptfor modern office landscapes
TASK AREA concepts are more
than just a response to current
trends. They provide evidence
of these trends and offer inno-
vative ways of implementation.
Modular axial flexibility
The wish to provide a property
with fittings suitable for both
current and future requirements
has resulted in the trend towards
axis-based room design. Accor-
ding to a Gallup poll, 75 % of
businesses have responded to
changes in work processes by
reorganising the layout of their
office premises in recent years.
Demand for modularity in spe-
culative properties is even more
striking. Developers must expect
tenants to change continuously
and must rely on variable room
fittings and layouts. Modern
systems enable and increase
axial flexibility.
TASK AREA concepts take the
following into account:
New models of building planningand room design
The use of new screen technologies
Lifecycle management and optimum
ratio of operating costs to invest-
ment costs
Peoples desire to deal responsibly
with energy issues and personnel

All-round glare control for
sloping TFT display screens
New developments in telecom-
munications call for progressive
lighting concepts. Increasing
numbers of laptops and orga-
nisers with steeply inclined dis-
plays are now in use and a
larger number of workstations
than ever must be ready to meet
these special requirements.
In particular, the arrangement
of luminaires directly above
workstations, dependent on
room axis orientation, makes it
necessary to reduce luminance
levels at steep angles in order
to minimise annoying reflections
on the screen.
Cutting operating costs
Over a buildings entire lifecycle,
the operating costs to the ten-
nant are anything up to three
times the original amount in-
vested. This, in itself, is suffi-
cient reason to make sure, from
the outset, that operating costs
are given due consideration.
According to analyses carr ied
out by the Hypo Vereinsbank in
Austria, 15 to 20 % of the total
costs of a tennant are spent on
facility management. These
costs include the operation and
maintenance of lighting systems.
In addition, there will be increa-
sing pressure to categorize buil-
dings according to their energy
use. By making it possible to
concentrate on actual visual
tasks and by providing mainte-
nance-friendly luminaire systems,
TASK AREA concepts make it
possible to keep these costs
low. Efficiency can be further
boosted by the use of intelligent
lighting controls.
Exploiting the design freedom
afforded by EN 12464
The TASK AREA concept is
backed up by the recently pub-
lished EN 12464 standard. This
standard specifies quality crite-
ria for the respective visual task
area, thereby allowing rooms to
be designed and fitted with
equipment in a differentiated
manner. The revised European
standard supports the TASK
AREA concept and prov ides
approaches to lighting design
that are more in line with the
real needs of the individuals
working in those spaces.

Individual TASK AREA
Selective, task-oriented lighting
of individual workstations is the
most original type of task-area
related design. A prerequisite is
precise definition of the position
and size of the visual task areas.
Detailed assignment provides for
maximum focusing of quantity
and quality of light.
Once individual workstations
have been defined as TASK
AREAs, the lighting scene can
be adjusted completely individu-
ally. The lighting is matched to
the individual requirements of
office users.
Surrounding area
Not only the visual task but
also requirements in terms of
convenience and spatial effect
in accordance with peoples
needs determine the lighting
technology deployed in the
surrounding area. There are
almost no limits on design free-
dom. Wallwashers, spots, light
walls, uplights and downlights
provide a wealth of options for
individual lighting solutions for
corridors and break-out areas.
TASK AREAstrip
Flexibility is increased by extend-
ing the TASK AREA to comprise
several workstations. Desks can
be rearranged within a TASK
AREA strip and can subsequently
be regrouped or sub-divided.
Combined with modern lighting
control systems, no major in-
stallation work is needed to re-
address luminaires, in order to
adapt to changes in the office
structure. A buildings flexibility
and modular character is de-
fined by its axes. Axis-based
design is exploited by TASK
AREA concepts which focus on
visual tasks for lighting design.
Despite this, they do not reduce
options for change within the
axes of the room.
TASK AREA room conceptsfrom individual workstations to modularstructures
TASK AREA strip: several workstations are grouped
together into a TASK AREA strip to achieve opti-
mum balance between modular axial flexibility and
focusing.
Individual TASK AREA:
if the area and nature
of the visual task have
been defined exactly,
the potential for con-
centration will be fully
utilised.

Intelligent luminairesneed-driven lighting management
Straightforward instal-
lation, flexible use of TASK
AREA thanks to LUXMATE
TASK AREA concepts focus on
individual task areas. Flexibility
can be retained and both TASK
AREAs and surrounding areas
can be modified with the help of
DALI.
Deploying DALI technology mini-
mises effort in terms of design
and installation. In contrast to
conventional installations, no
switched phase conductors are
needed for each luminaire in
the case of DALI-addressable
luminaires. Predefined lighting
levels for TASK AREAs, shelf
surfaces and surrounding areas
also speed up commissioning
significantly.
This flexibi lity is evident through-
out the entire lifecycle of the
system. Using LUXMATE Flexis,
a product in the new LUXMATE
LITENET product family, lumi-
naires located anywhere can be
grouped together into TASK
AREAs or room areas, without
any intervention in the installa-
tion.
This system boasts the same
functionality as conventional
DALI lighting control but is
significantly more affordable.
Whereas in the past only
dimmable luminaires could be
managed individually, now
switchable lighting systems, too,
can be adapted quickly and fle-
xibly in response to changed
requirements or new tenants.
Application benefits:
Change of TASK AREAs in the
space
Adaptation of TASK AREAs to
changed room sizes according
to building axes
Re-organisation at the click of
a mouse
Graphical user interface for
easy use of software
Facility to settle accounts re-
lating to specific customers
Simultaneous blinds manage-
ment, if required
Before: conventional
installation using bus
relay involved consider-
able effort in terms of
design and installation.
After : DALI-a ddressable
luminaires significantly
reduce effort in terms of
design and installation
further benefits include
lower fire loads and
switching loads.
The first steps towards
an innovative lighting
solution: definition of
ambient areas and
assignment of lumi-
naires to several TASK
AREAs.
Migration takes place
without any intervention
in the installation. Using
LUXMATE Flexis, a
product from the new
LUXMATE LITENET
product family, rooms
and TASK AREAs can
be adapted at the click
of a mouse.

Maintenance Control:
constant illuminance cuts
energy consumption
Automatic i lluminance control
is also an element within the
task area concept. International
standards specify levels of illu-
mination which must be maintai-
ned. Since the light produced
by a luminaire varies over time
(due to build up of dirt on reflec-
tive surfaces and reduction of
lamp output), higher light levels
need to be installed initially to
achieve the stipulated levels
later on. However, it makes bad
economic sens to fully utilise
this excess capacity.
LUXMATE Flexis with Mainte-
nance Control precisely adjusts
the lighting level to the bare
minimum required. The system
takes account of the mainte-
nance factor established by the
Dimming on demand:
addressable meansdimmable
Using TASK AREA concepts,
the quality of lighting can be
optimally matched to users
needs. One essential criterion
is individual dimmability of the
luminaires this enhances the
value of a property. However,
there are various reasons for
not deploying this function from
the outset: lower investment
costs during construction, for
instance. Addressable luminaires
with a dimming on demand
function can easily be upgraded
to become dimmable luminaires
without intervening in the instal-
lation. The upgrade can be
acquired in the form of a dimming
licence thereby allows additional
costs to be billed only to those
tennants who wish to utilise the
additional function.
Longer maintenance
intervals thanks to
higher illuminance
levels
Maintenance intervals
can be prolonged by
over-dimensioning the
system. Up until now,
increased energy con-
sumption made it un-
advisable to do this.

vestment and operating costs.

Summary for a 15-year analysis period
Operating and maintenance costs are a crucial
factor and, in most cases, actually exceed
investment costs.
Every lighting concept has its own performance
profile that may result in preference being given
to it, depending on project-specific priorities.
Factors such as convenience, flexibility and
innovation are difficult to quantify. These criteriaare overlooked if a system is assessed exclusively
in terms of investment costs.

Saving energy
Extra investment in Maintenance Control with automatic
compensation for over-dimensioning and daylight-dependent
lighting control pay for themselves through energy savings
alone. Aspects such as quality of user interaction, room-zone
management, additional monitoring functions and much more
(see pages 12/13) provide added value.

Considerable reduction in operating costs thanks to longer
maintenance intervals
Over-dimensioning a lighting installation ensures that the main-
tenance illuminance levels required in standards are met during
actual operation, not just when the system is new. The extent
of over-dimensioning has a decisive influence on the duration
of the maintenance interval. LUXMATE Flexis with Maintenance
Control compensates for over-dimensioning, thereby reducing
energy consumption. LUXMATE daylight-dependent controlprovides scope for further potential energy savings.
The aim is to strike the optimum balance between luminaires
fitted, number of luminaires and photometric characteristics in
order to minimise the costs of the maintenance work required.

Standards and quality criterialighting design fundamentals
The EN 12464 standard is
changing old design habits. It
allows designers greater freedom
and, above all, dictates that
lighting must be delivered in the
location where people have to
perform their visual tasks. At
the same time, it specifies com-
prehensive quality criteria for
a good lighting solution.
EN 12464 introduces the con-
cept of the visual task area
where photometric quality
criteria must be met. This area
is any surface on which visual
tasks are performed and can be
horizontal, vertical or inclined.
Amaintenance illuminance of
0.7 and uniformity (the mini-
mum-to-mean illuminance ratio
in the area of the visual task)
must be adhered to.
Maintenance factor,
maintenance value and
maintenance intervals
Every lighting installation ages
and illuminance drops off due to
a decrease in the luminous flux
of lamps and the soiling of light
sources, luminaires and the
room. The designer must spe-
cify the particular maintenance
measures and intervals that
must be adhered to in order
to preserve the maintenance
illuminance. This results in a
maintenance factor that ensures
the maintenance illuminance
throughout the duration of the
maintenance interval. If detailed
information is not available,
Zumtobel Staff recommends a
reference maintenance factor of
0.67 inspired by BGI 856 Office
Lighting.
The following maintenance illuminances (excerpt from EN 12464-1 Light
and lighting. Lighting of work places Part 1: Indoor work places) apply for
essential office visual tasks:
Nature of room, visual task or activity Em UGRL Ra
Filing, copying, circulation areas etc. 300 19 80
Writing, reading, data processing 500 19 80
Technical drawing 750 16 80
CAD workstations 500 19 80
Conference and discussion rooms 500 19 80
Reception area 300 22 80
Archives 200 25 80
Em = Maintenance illuminance
UGRL = Unified glare rating
Ra = Lower limit for colour rendition index
This means that the new stand-
ard differs from the old approach
in which the design objective
was to achieve average illumi-
nance throughout the room. In
the surrounding area where visual
tasks are performed less often,
illuminance can drop down to
300 lux. In offices, areas where
visual tasks are performed
essentially include the desk and
the adjacent circulation area.
Zumtobel Staff recommends
compliance with quality criteria
within this task area (see also
BGI 856 Office Lighting, an
informative brochure published
by organisations in charge of
accident insurance and lighting
companies in Germany, Austria
and Switzerland).
Additional qual ity criteria:
Well-balanced luminance
distribution in the visual field
ensures visual performance
and visual comfort. This
means that great importance
is attached to visible vertical
surfaces and how they are lit.
Glare control at workstations
must never exceed the UGR
limit of 19 in order to prevent
annoyance due to direct glare
caused by luminaires.
At visual display terminals,
luminance levels on surfaces
that could be reflected on the
screen must not be too high.
For luminaires, a mean lumi-
nance of 1000 cd/m2 must not
be exceeded above 65 to the
downward vertical.
