Sustainable lighting with LED
Not only does the technological
revolution of the LED mark a major
step towards energy efficiency,
it also drives an intelligent implementation of new products and
lighting concepts that, in turn,
deliver new standards of quality –
for sustainable architectural lighting based on human perception
– such as here at Bosch Siemens
Hausgeräte in Hoofddorp, where
ERCO’s LED light was used to create
the first “Cradle to Cradle” office
building in the Netherlands.

Planning practice with LED:
“100% LED is a realistic vision”
Renovations at the town hall in Schorndorf near Stuttgart, a project ­involving
LED lighting supplied by ERCO, are nearing completion. In September 2012, we
talked to architect Gunter Fleitz (Ippolito
Fleitz Group) and lighting designer Prof.
Stefan Hofmann (Lichtwerke) about their
experiences and deductions regarding
the use of LED lighting in a real-life situation.

“100% LED” has now become common practice
in many projects. This Lichtbericht is entirely
focused on LEDs and provides an overview of
the diversity of applications for this new technology. It shows, without a doubt, that the LED
has now advanced well beyond its initial applications and has replaced conventional sources
in many projects.
ERCO embraces this change in technology,
and, as in the past year, our 2013 innovations
are 100% LED. Pages 14 to 17 offer an introduction to these new products – they have followed
the same path of deploying LEDs whenever
possible, thereby satisfying our ­clients’ interest
in using superb, ground-breaking LED technology in a wide range of performance levels and a
multitude of applications.
The projects described in this Lichtbericht
are designed to give you an impression of the
many different uses of LED lighting. It starts off
with the headquarters of Bosch Siemens Hausgeräte (BSH) in the Netherlands from page 6
– an office and showroom project based entirely
on the “Cradle to Cradle” concept; from the
moment of architectural planning and design,
its whole object is to promote both ecology and
sustainability. The outcome is a building that
combines modern aspects with ecology into a
dynamic symbiosis of modern relevance.
A first-hand report on lighting at the town
hall in Schorndorf, using LED lighting tools,
is provided from page 10 onwards. Architect
Gunter Fleitz from Studio Ippolito Fleitz in
Stuttgart and lighting designer Stefan Hofmann from Lichtwerke in Cologne recall, in
great detail, their experiences of planning and
implementing LED lighting for the renovation
of the town hall – a project they sum up as one
that will pave the way for 100% LED solutions
in architecture.
Duvetica – still a young fashion concept
for down jackets – has now opened its fourth
showroom in Milan based on designs by Japanese architect Tadao Ando. Light as a feather,
the down jackets are displayed in trendy colours
in a space of 220m2 and stand in delightful
contrast to the minimalist severity of the concrete architecture devised by Tadao Ando. The
store is illuminated entirely with Logotec LED
spotlights and Quintessence LED recessed luminaires. All in all, a showroom concept in which
the sophistication lies in its clear simplicity.
In a ranking of the 100 top hospitals in the
Netherlands, the Ikazia hospital in Rotterdam
took second place. This high medical standard
is equally evident in the hospital’s architecture.
The new main entrance suggests the ambience of the foyer of a elegant, modern hotel.
The pleasant atmosphere is underscored by an
LED lighting concept that helps visitors find
their bearings, as warm white light adds to the
friendly reception in the building.
LED light in the historic rooms of the Palazzo
Anguissola in Milan was used with impressive
effects in an application that pays respect to
the building’s fabric. Here, the light is designed
primarily to serve and so should harmonise
discreetly with architecture – this was a prom­
inent aspect for this project. The Optec LED
spotlights accentuate the works of art inconspicuously, but are equally effective in illuminating the architecture, thereby forging an
elegant link that extends from the past to the
future of light.

BSH headquarters Netherlands, Hoofddorp
Cradle to Cradle, a concept for sustainable
and ecological architecture. As a company,
BSH Bosch Siemens Hausgeräte has consistently implemented this concept in its new
sales office building in the Netherlands
– right down to the aspect of efficient and
comfortable lighting using ERCO’s LED
technology.
If it can be said that every nation has certain
characteristics, these are no doubt shaped by
their respective environments. The Nether­lands
owe large parts of the Dutch territory today to
its age-old wrestle with the North Sea. Many
people in this small, yet densely populated and
highly productive country maintain a pragmatic
attitude to nature, a clear commitment to environmental and climate protection and – as many
parts of the land are, after all, below sea level
– an appreciation of good design as a means of
popularising technical and social innovations for
acceptance.
It should therefore come as no surprise that
German chemist and environmental ­visionary
Michael Baumgart successfully set up a “Cradle
to Cradle” (C2C)* chair at the Erasmus University in Rotterdam, where he conducts further
research into this approach to ecological production, which he developed in partnership
with American architect William McDonough.
McDonough has now put the C2C concept into
practice at the first office park of its kind in the
Netherlands – in Hoofddorp, a town founded
in the 19th century in the Polderlands, south of
Amsterdam. An anchor point of the site dubbed
“Park 20/20” is an office building designed by
McDonough, which serves as the Dutch sales
office of German home appliance group Bosch
Siemens (BSH), but also as a showroom and an
interpretive experience of the company’s Bosch,
Siemens, Neff and Gaggenau brands.
Sustainability has long since been a corporate
objective of BSH, yet the new building takes it
a step further still with C2C. Here, the aim is to
recycle all used materials or return them to the
natural environment. With features such as
high efficiency, long life and easy recyclability,
ERCO’s LED lighting tools qualify for illumination of this project – but equally because of
their superior light quality. This, in turn, helps to
drive greater acceptance of ecologically sound
solutions among the building users.
The interior design was devised by D/Dock
in Amsterdam. Its design concept combines the
ultimate experience of the BSH brand with a
unique work environment, themed around the

aspects of ecology. This aesthetic union results
in a welcoming place for visitors that radiates
a sense of calm and openness. Optimal ­lighting,
tactile materials, soft colours and flexible design
elements throughout underline this approach
– clarity on the whole, with attention to detail.
The cooking school in the building shows just
how flexible this concept really is. Here, the different brand appliances can be swapped with
each other in next to no time, so that the facility can be shared by all brands. Flexible lighting
tool, such as spotlight and track systems, are
integrated effortlessly into this environment.
At the centre of the office is a four-storey
atrium with an indoor/outdoor Living Green
Wall and a building-integrated photovoltaic
glass roof which satisfies the goal of renewable
energy.
In the public areas and showrooms of BSH
brands Bosch, Siemens, Gaggenau and Neff,
the effective lighting concept used by BSH in
Hoofddorp is oriented around accent lighting.
Here, the designers opted for Logotec LED spotlights for track mounting. They can be flexibly
positioned and aligned, while their Spherolit
lenses – which are easily replaced without tools
– provide beam characteristics ranging from
spot and wide flood to oval flood or wallwash.
Other efficient lighting tools, used alongside
different types of LED spotlights, include LED
recessed luminaires from the Quintessence
range, but also luminaires from the Compact
100 range with compact fluorescent lamps.
Their purpose is to provide situation and
­perception-oriented lighting. Efficient visual
comfort as a leading principle maintained at
ERCO fits ideally in this project with the cradleto-cradle concept of the building, helping
to present the BSH brands and products in an
attractive and future-oriented light.

atrium contribute to the
open, inviting character
of the building.

A Living Green Wall across
the four storeys of the
atrium is a symbol of the
ecological nature of the
architecture. Common
areas such as conference
rooms or staff cafeterias
are positioned around
this sector. Mounted on
track systems freely suspended in the room, the
­narrow-beam Logotec
LED ­spotlights bridge even
large distances between
luminaire and target sur­
face.
Oval flood
ERCO’s LED lens systems
with Spherolit technol­
ogy produce an oval flood
beam as one option,
which is suitable for the
efficient illumination of
long objects or surfaces,
but also produce light
strips for wide luminaire
spacing.
The auditorium is used
both for internal purposes
and for public events –
from marketing training
through to jazz concerts.
In this area, Logotec LED
spotlights with oval flood
characteristic help to
model the physical makeup of the wall panelling
without causing glare.

Planning practice with LED:
“100% LED is a realistic vision”
Renovations at the town hall in Schorndorf near Stuttgart, a project ­involving
LED lighting supplied by ERCO, are nearing completion. In September 2012, we
talked to architect Gunter Fleitz (­Ippolito
Fleitz Group) and lighting designer Prof.
Stefan Hofmann (Lichtwerke) about their
experiences and deductions regarding the
use of LED lighting in a real-life ­situation.
again for its energy-efficient refurbishment.
The last restoration in the 1980s had left it
with many features in dark wood as well as
terracotta-coloured flooring. We wanted
to get rid of these and have a more open
façade again to create transparency from the
marketplace into the building. The Wedding
Chamber now sits, as it were, as a glass struc­
ture inside the building. Separated by glass
walls, the foyer and chamber converge into a
single room differentiated by filters such as
curtains and point grids printed on the glass.
The acoustic ceiling throughout is curved
around the perimeter and has continuous
holes to maintain this space continuum.
Gunter Fleitz:
We had already worked on a restaurant pro­
ject together. We had urged our clients to
hire a lighting designer. Our basic interior
design concept included initial ideas on
lighting, which we expanded together. We
often use 3D software for our designs, so
very early on we had visual simulations of
the room to hand. At the same time, when
we got to the detailed lighting design with
Stefan Hofmann, all options were still open
in terms of exact definition.
Martin Krautter:
Mr Hofmann, what was your first impression?
Stefan Hofmann:
I knew from our previous project how the
architects worked, what was important to
them, and how they approached things.
The lighting is always only as good as the
architecture and in the best-case scenario
it reduces itself to enhancing superb archi­

Martin Krautter:
Mr Fleitz, why don’t you start by telling us a
bit about Schorndorf’s town hall?
Gunter Fleitz:
The town hall dominates the historic market­
place in the heart of the old town and is the
town’s “landmark”, built around 1730, and
is now a listed building. The semi-basement
with its distinctive arcade windows used to
be an open hall where the market took place.
The arcades were later closed to produce a
foyer that is now used for many purposes
including tourist information and events.
There are also two multifunctional rooms –
the large Council Chamber is used for events
such as technical committee meetings and
seminars. Above it lies the built-in Wedding
Chamber, which also serves as the session
room for the Lord Mayor and his team.
Martin Krautter:
What state was the town hall in when you
first saw it?
Gunter Fleitz:
When we started the project in 2007, the
building was in desperate need of renovation
due to significant shortcomings in terms of
fire protection and building infrastructure.
The young Lord Mayor was also keen for
the town hall to get a makeover that would
give it, and so the town itself, a new image.
When the economic crisis hit in 2008, the
project was put on hold until funds came in
10 ERCO Lichtbericht 95
Martin Krautter:
What specifically were your clients looking
for?
Gunter Fleitz:
The functional requirements did not change
substantially. We have a variety of complex
uses, but we did not want to design a mul­
tifunctional room as a sort of “jack of all
trades and master of none”. Special focus
was given to creating a stately entrance and
transparency, also to the Chamber. Closed
sessions required the option of appropriate
discretion. Relatively early on, we presented
a visual concept that would considerably
change the character of the room. Our c­ lients
were highly enthusiastic about it, and it
allowed us to show them what the concept
could offer.
Martin Krautter:
Which brings us right to the point – trans­
parency always has a lot to do with lighting.
How did you come to cooperate with Stefan
Hofmann as a lighting designer?
Martin Krautter:
You actually calculated these costs?
­ esktop of a single workplace precisely? The
d
result shows that yes, it is possible. Glare
control is ensured using a completely differ­
ent technology, but it is available. There are
areas, however, where we could not install
LED technology because the right lumi­
naires here simply don’t exist yet – ceiling
washlights, for example, or recessed floor
uplights.
Stefan Hofmann:
Yes, and compared them to the acquisition
costs. In 2010, LED lighting systems cost
around a third more than conventional light­
ing. We presented these figures with the
architect to the Lord Mayor. We were quite
frank and said it may take a few years to pay
off these additional costs, but he would have
a building that demonstrates responsibility
and progressiveness. It didn’t take long for
him to decide on LED lighting for the whole
project.
Martin Krautter:
Did you ever, at any point during the plan­
ning, feel that LEDs would compromise on
quality?
Martin Krautter:
How did the contract come about, was there
a competition?
Gunter Fleitz:
No, we were directly contracted for the
project. We had a number of projects in
Schorndorf, the most recent ones a radiol­
ogy practice and a care home. At the open­
ing, we were introduced to the Lord Mayor.
He ­wanted to renovate the town hall with
­external experience and a new, uninhibited
attitude. The good thing was that the Lord
Mayor, the Town Councillor for Building and
Construction and the head of the Building
Department all knew what to expect and
were all on the same page.
lighting move in the same forward-looking
direction? At the end of the day, we con­
ducted an analysis calculating the energy
and maintenance costs for two lighting con­
cepts – one for conventional light sources
using metal halide lamps or dimmable halo­
gen lamps and the other for LED.
Gunter Fleitz:
No, but I must admit I have never really seen
the light at night. What really impressed me
was the colour rendering and the very agree­
able light colour everywhere.
tecture. As lighting designers, it helps us, of
course, when the architect communicates his
philosophy, what room is to have which func­
tion, and how you move through the rooms.
Gunter Fleitz:
We had a strong design vision that we were
able to work on together.
Martin Krautter:
When was the first time that you entertained
LEDs during the discussions?
Stefan Hofmann:
It was when we designed the sculpture-like
ring pendant luminaires in the foyer, which
were only feasible with LED lamps.
Gunter Fleitz:
We knew here that it would boil down to
using LEDs, yet not initially for the room’s
overall lighting concept. The issue then arose
in meetings with the client, who was open
to the idea, so Stefan Hofmann explored it in
more detail.
Stefan Hofmann:
It was obvious, for some areas, that we
would use LEDs – for vertical illuminance,
for instance, specifically for effective illu­
mination of the curtains. The next question
was how we would handle the lighting in
general. Should we use conventional lamps
or opt for modern LED technology? We have
open, transparent architecture – would the
Stefan Hofmann:
Similar to low-voltage halogen lamps, LEDs
are point light sources. Their superb integra­
tion into optical systems produces intense
and brilliant light exactly where it is needed.
You can see under the Wedding Chamber, for
instance, that it works really well now with
LED lighting.
Martin Krautter:
What is the light quality of the LED like in
terms of visual comfort or glare?
Stefan Hofmann:
A single, finger-sized lamp previously
­produced a very high lumen package. To
achieve the same luminous flux you would
need a grid of several light-emitting diodes.
Only in conjunction with a sophisticated
lens technology, such as ERCO’s, would you
get the result you are looking for. We ques­
tioned various scenarios with LED spotlights
in this project. For instance, is it possible,
from a height of 10m, to illuminate the
Martin Krautter:
But how do you ultimately decide on
one specific supplier, a specific brand like
ERCO?
Gunter Fleitz:
We were completely open when we started,
but Stefan Hofmann recommended your
products for many situations, as they are
simply ideal here. But with so many specific
lighting situations, you can’t get it all from
one source.
Stefan Hofmann:
It was relatively simple. Apart from the odd
decorative and functional exception, most
of the lighting comes as point light sources
from the ceiling. As a lighting designer, I
prefer to use a manufacturer that offers a
range, a complete portfolio. ERCO provides
LED downlights, wallwashers and directional
luminaires all with an exact and consistent
design, and these are the very luminaires we
needed: with the same diameters and a uni­
fied appearance.
Martin Krautter:
So there are design aspects and technical
aspects. Was it also a question of service?
Stefan Hofmann:
Initially it was a question of portfolio. For
the Chamber we needed LED directional
luminaires with a narrow beam angle of 10°.
The market, in this segment, is relatively
ERCO Lichtbericht 95 11
underdeveloped. ERCO was the pioneer, and
that ultimately tipped the scale for us. Fortu­
nately ERCO also quite recently changed the
light colour from warm white to really warm
white.
Martin Krautter:
That means we use LEDs with a colour tem­
perature of 3000K in the project?
A new image for Schorndorf’s “landmark”: Located
in the heart of the town,
the historic town hall with
its multifunctional rooms
on the ground floor plays
a crucial role in public
life – this is where visitors
are welcomed, medals are
awarded, election victories
are celebrated, marriage
ceremonies are conducted.
Gunter Fleitz:
Yes, this significantly increases acceptance.
I don’t believe our architectural style is plain
and sober, we use coloured, albeit quite dark,
textiles, complemented by natural stone.
Nonetheless, the unusual stylistic features,
the modernity of the glass architecture – the
warm light makes it easier, it simply feels
nice.
Stefan Hofmann:
Yes, and you get ideas what the next step
could be. We already have custom-built
lumi­naires in the project that are fitted with
a mix of LEDs in 3000K and 4000K. We can
therefore either produce warm light or com­
plement daylight with neutral white light as
needed. We want to see the same for down­
lights and wallwashers, that they can easily
be switched between these light colours.
Finally, a directional luminaire with a light
colour of 3000K that gets warmer still when
dimmed – that would be perfect for restau­
rants, for instance.
Gunter Fleitz:
I think it’s only nuances that are currently
still missing. When we had a recent tour of
the project with the Lord Mayor and the
Town Councillor for Building and Construc­
tion, we could still sense some nervousness
about the generally half-finished work, but
they did say, “The light is superb, sensational,
let’s hope the rest is the same...”
Martin Krautter:
That’s what one likes to hear!
Gunter Fleitz:
It’s true, there were still things not quite
­finished yet, but you could sense the ceremo­
nious atmosphere already.
Hendrik Schumacher:
The colour rendering properties are also
excellent. The colour scale with its beige and
brown tones is well-served with this colour
temperature.
Martin Krautter:
The town hall has not been officially opened
yet, what phase are we currently in?
Gunter Fleitz:
The offices on the upper floors are now
­moving back in. Official business in the town
hall will resume on Monday, but not on
the ground floor yet. The grand opening is
scheduled for 8 October.
Martin Krautter:
Mr Hofmann, you have already seen the
lighting at night – what is your opinion?
Ippolito Fleitz works
intensively with 3D software from the design
stage. The strong visual
concepts produced as a
result are designed to win
over the clients (top). It
speaks to the quality of
the architects that the
concepts lose none of the
fascination after implementation.

Stefan Hofmann:
It is exactly as we had hoped it would be.
The light of the downlights illumi­nating
the various areas is intense and brilliant, but
also highly uniform. The same goes for the
directed light. The change from conventional
­lighting to LED sources was a success – it
works. It was a rewarding project and helped
us gain further experience. We will know in
future projects what wattages, what charac­
teristics, what systems to use.
Hendrik Schumacher:
You are starting to get a feel for LEDs?
Stefan Hofmann:
It only works when you have good architec­
ture. When you trust each other, listen to
one another – then you can work in fruitful
partnership.
Gunter Fleitz:
It also helped that we weren’t too short of
time. The dry construction work on the float­
ing ceiling panels was time critical. The lumi­
naires and the mounting rings needed to be
available on time here. It all worked out fine
though. Or, when we were talking beam char­
acteristics, you said, “I had actually imagined
it a little softer”...
Stefan Hofmann:
The 10° option was simply too narrow in a
few places, where the ceiling was much lower
because of ceiling joists. There were, how­
ever, other lens options, from spot and flood
through to wide flood. We tried these and
ended up changing them.
Martin Krautter:
We are definitely taking a close look at
all these issues. The sector at the moment
is indeed undergoing enormous changes.
Would you say that the LED has become
a focal point in lighting design, and also
believe LEDs to be the way into the future,
as other lamps will cease to be available or
be banned?
Gunter Fleitz:
What I have seen in Schorndorf, so far, has
really encouraged me and shows me that we
can choose LED for future projects without
hesitation. The project will reach a new
standard of quality.
Martin Krautter:
The Spherolit lenses actually do make LEDs
more flexible than conventional lamps –
does that make it easier for the designer?
Stefan Hofmann:
Same from my side – this experience makes
me optimistic. If the beam of the LED direc­
tional luminaire is too narrow, you simply
exchange the lens and don’t need to install
new luminaires. This flexibility gives you
­certainty. I have a good feeling about this.
Martin Krautter:
So you believe architecture with 100% LED
is a positive, realistic vision?
Stefan Hofmann:
That was an interesting experience –
I phoned ERCO on Wednesday, the lenses
arrived by 10 a.m. on Thursday, and on
­Friday, I was in Schorndorf to replace them.
That’s what I call stellar service.
Stefan Hofmann:
Absolutely, yes.
Martin Krautter:
Mr Hofmann, is there anything else you
would like to see in terms of product infor­
mation, product documentation for LED
products?
Martin Krautter:
Thank you both for the interview and for
the nice closing comment!
Stefan Hofmann:
Clear standards for technical data and meas­
urements would be helpful for designers
and manufacturers. With ERCO, I know that
such data as luminous flux or luminance on
the target surface are realistic. At the same
time, I guess it will take a few years yet for a
standardisation of data. Another issue, if I
may, is the enormous price pressure because
of a changed market situation with alto­
gether new providers. Not all clients are pre­
pared to spend a third more initially on LED
solutions.
Hendrik Schumacher:
We all know what it’s like – new technolo­
gies cost more at the start before the price
comes down. The expectations for LED
technology are the same, and, as suppliers,
we need to deal with that.
Stefan Hofmann:
Well, conventional lighting systems will ­likely
soon be replaced by LED systems, but the
market setup here is completely different.
That makes the question of price and prod­
uct portfolio a legitimate one. Of course, it
would be nice to get a simple LED downlight
at a reasonable price – with ERCO’s quality.
Gunter Fleitz:
This project has certainly paved the way
here.
Ippolito Fleitz Group, Stuttgart
The multidisciplinary, ­internationally
active design studio sees its role as
­"identity architects” – together with its
clients, the team develops architecture,
products and communication always as
part of the whole and yet as something
entirely unique. Its two managing partners, Peter Ippolito and Gunter Fleitz,
set up the studio in 2002, after they had
already been working together at zipherspaceworks since 1999. Their work has
earned them many design awards – outstanding projects include the new canteen
for the German magazine DER SPIEGEL,
the exhibition stand for Burkhardt Leitner
constructiv and the Palace of International Forums in Uzbekistan.

Fascinated by the subject of light, Stefan
Hofmann has spent his time since his studies of scenography and exhibition design
working with this medium in the context
of theatre and architecture. Alongside
well-known lighting designers, he gained
experience as a project manager in such
undertakings as the Jahrhunderthalle in
Bochum or the Uniqa Tower in Vienna.
Many of his projects have won international awards. In 2008, after various university teaching positions, he accepted a
chair of lighting design at the University
of Applied Sciences in Kaiserslautern. In
2009 he set up his own office – “Lichtwerke” – to design light projects individ­
ually from start to finish.

Advice and logistics for perfect light
Contact
The global ERCO team
looks forward to getting
to know you. You will
find the addresses of our
offices and showrooms
at:
www.erco.com/contact
Light in space
The effect of light in
space is difficult to
express in words – it
must be experienced.
The ERCO showrooms
provide ideal, flexible
facilities for such demonstrations.
Anyone who starts a project will usually be aiming to find the best solutions. The material has
to be just right, the design must be optimal, the
lighting perfect. The end result should be unique
and distinctive, bearing the hallmarks of the
creative mind behind it, the one who fought so
passionately for his or her ideal. Achieving this
goal for architects and lighting designers often
means involving ERCO and its products in the
planning.
The most obvious place to start today –
­accessible anywhere and that 24/7 – is the Light
Scout at www.erco.com. ERCO’s website provides
an overview of products, projects, specifications and also gives quick access to the contact
data of the many competent regional experts
in ERCO’s worldwide lighting network. Trained
employees in 35 cities are at hand to answer
personally and competently all question clients
may have right from the point of planning. They
are there to provide advice during the planning
stage, assist with lighting aspects throughout
construction, and ensure the familiar high quality standards as an after-sales service.
For clients, the major advantage of this sales
network is to be able to see products in action on
site, to experience light in the showroom or in
existing architecture. Designers no longer need
to trust catalogue data blindly; rather, the lighting effect can be observed and compared first
hand. ERCO will even stand up to a comparison
with competing products in mixed sampling
inspections – these, after all, illustrate most viv­idly the superior performance of ERCO’s own
products.
18 ERCO Lichtbericht 95
Once the decision has been made in favour of
ERCO, there are many other services available to
the client including advice in the construction
phase or the provision of facilities for planning
and other project meetings. This allows architects to concentrate on the core aspects of their
work, while availing themselves of the expertise
and in-depth know-how of our highly trained
team.
As well as giving technical support, ERCO
also lends a helping hand in the lighting design.
Our lighting advisers in the offices and showrooms see their role as being “consultants to
the consultant” – providing professional advice
to designers in all matters relating to ­lighting
technology and in each individual project phase.
If challenges are encountered, there are also
many experts available at ERCO’s head office
who can be consulted to work out a quick solution – always with a view to ensuring the success of the whole project.
Visualisations and simulations are increasingly instrumental in the planning process.
Reliability of the manufacturer’s data is crucial
to the designer. To this end, ERCO attaches great
importance to exact and reliable values from
its laboratories for all photometric data made
available for use in DIALux and other software
with specific formats such as IES.
ERCO’s mission is to provide solutions in the
project process. This includes helping clients
with luminaire focussing, commission a lighting
control system, or with maintenance aspects.
This service to the client ensures that the promised performance of the luminaires and the
control system, and with it, the effect in the
room, is guaranteed at all times in every respect.
A further important aspect in the building process is the logistics. Nothing is worse in project
planning than when planned materials are not
available at the agreed time or when they are
constantly in the way because they have been
delivered too early. ERCO can help plan delivery
dates to the day. Planning and delivery as a
result mesh seamlessly – minimising logistical
problems.
Irrespective of the specific project, our
regional teams see it as their role to embed
the issue of architectural lighting in the minds
of architects and lighting designers, but also
contractors and owners, through seminars
and other events. Many ERCO showrooms and ­
offices around the globe have, as a result,
become meeting places for local lighting and
architectural specialists.
Project management
The offices provide
ideal facilities for project
meetings. Your ERCO
contact is trained to support clients through all
the stages of a project.
Light qualities
A wide variety of ready
mounted, operable
luminaires ­individually
addressable through
connection to a lighting
control system allows
demonstration of even
subtle light qualities in
the showroom.
On-site support
ERCO employees on
site lend a helping hand
when it comes to focussing the luminaires correctly and commissioning
the lighting control system. This ensures that all
components are perfectly
coordinated.
Events and seminars
These turn ERCO showrooms into meeting
­places for the local light
and architecture scene.
The showroom is designed
to make it possible to
explain the concept of
“tune the light”: to design
the qualities of light in
terms of time and space.
ERCO Lichtbericht 95 19
Focus
Efficient LED lens systems for
downlights: Technology
In developing the new LED lens
system for general lighting, ERCO
focused specifically on factors
such as compact functional style,
­shallow depth, simple system
design, efficiency and visual com­
fort. To provide optimum glare
control in downlights for conventional lamps, the lamp is recessed
from the mounting surface in an
almost concealed position – with a
corre­sponding height of the lumi­
naire. The much smaller dimensions of LED packaging are already
advantageous, and combined with
the new lens system and glare control, this makes for exceptionally
compact, yet highly efficient luminaires with good visual comfort. In
order to minimise loss due to the
the refractive index for reflections
as well as the transitions between
several lenses and air, the lens
system combines two components
– the collimator to focus the LED
light and the lens for the required
light intensity distribution. The
very principle of the one-piece lens
­system enhances the effi­ciency
even in contrast to other LED
downlights with light mixer and
Darklight reflector or a two-piece
system with collimators. While
the flexi­bility of ­interchangeable
Spherolit lenses is a crucial advan­tage in spotlights, it is less signifi­
cant in downlights meaning that
efficiency can become the ­primary
goal. Glare control is ensured
through a flat cross baffle. It reduces the view of the LED with its high
luminance and improves the visual
comfort.
Double focus
Efficiency with compact
lighting technology
A light output ratio (LOR)
of up to 87% illustrates
the efficiency of the new
LED lens system compared
to conventional recessed
luminaire designs. At
ERCO, the entire optical
system – from the calculation and design to the dies
and tools in production –
is produced in-house.
Precise lighting
­technology
The one-piece lens system
made of optical polymer
is notable for its high efficiency and striation-free
beam for general lighting.
It lends a distinct and
attractive appearance to
products fitted with it.
Lens system wide flood
The collimator functions
by aligning the light into
a parallel beam. The upper
circular lens then creates
a rotationally symmetrical
light distribution.
Lens system oval flood
The upper parallel ribs
of the lens system bend
the rays of light to pro­
duce an axially symmet­
rical light distribution.
The oval beam is aligned
as required by turning
the luminaire insert in
the mounting ring.
Efficient LED lens systems for
downlights: Application
The size of a luminaire factors as
highly in its efficiency as does its
price and operating costs, since
compact luminaires save space
and ease the planning process.
Earlier luminaires with a very flat
design had occasional issues with
glare control due to their depth.
The cross baffle of the Compact
LED has a cut-off angle of 30°
resulting in good visual comfort
despite the reduced depth. Direct
glare is minimised and the attention of the observer is directed
onto the illuminated surface.
The two different light distributions of Compact LED solve
different lighting tasks. The wide,
round beam is used for the efficient general lighting of surfaces
and spatial zones, particularly for
product presentations. The oval
beam, on the other hand, is suitable for the illumination of rows
of tables, counters or pathways
with wide luminaire spacings. The
system design of the compact
LED recessed luminaires presents
a variety of options from medium
to high lumen packages thanks to
­different luminaire sizes and technical adaptation to suit the architecture. Round luminaire apertures
feature in Compact LED and square
ones mark Quadra. Compact LED
is also available with an increased
IP rating for outdoor or damp
­environments.
Good visual comfort
for workplaces
The cut-off angle of 30°
in recessed luminaires
ensures good visual
comfort when used for
general lighting of traffic
zones and workplaces.
Wide flood
The wide, rotationally
symmetrical distribution
is suitable for the general
lighting of outdoor areas
such as arcades, passages
and traffic zones.
Thomas Schielke
Oval flood
The axially symmetrical
light distribution is ideal
for efficient and uniform
illumination of pathways.

The business idea to focus a fashion label solely
on down jackets took a detour via Japan to bring
with it architecture designed by Tadao Ando – so
goes the story of Duvetica in a nutshell. In 2005
Giampiero Vagliano and Stefano Rovoletto,
two experienced fashion designers, lauched the
label and started sales in Asia with great success.
The recipe: superior European quality of material and workmanship, ethically correct origin of
the raw down material from the Périgord – and
trendy, unusually figure-hugging cuts that have
revolutionised the conventional image of voluminous down. Duvetica now operates four shops
in Tokyo, Kitzbühel, Courmayeur and Milan, each
designed by Tadao Ando, the Japanese master
of architectural minimalism. Special feature of
the latest store in Milan’s Via Santo Spirito, a side
street of the Via Montenapoleone fashion mile
– the premises are illuminated throughout using
LED technology supplied by ERCO – as a sustainable investment with optimum light quality.
The premises spread across two levels, each
having around 220m2 of space, placing the
store on the ground floor and a showroom for
resellers in the basement. No design would be
complete without Tadao Ando’s trademark –
immaculate exposed concrete in Tatami grid
style. Two side walls made of this material divide
the room and together with light plastered ceil­
ings and dark grey cement flooring provide a
neutral background for the brightly coloured
jackets, which are displayed effectively in backlit
shelved niches. The grazing light added by Nadir
recessed floor luminaires brings the otherwise
clinical concrete surfaces to life, as brilliant light
accents produced by the Logotec LED spotlights
give prominence to the shiny material of the
down jackets. Technical details such as the large
flat screen monitors, track and recessed ceiling
luminaires integrate seamlessly with the architecture. In this way, the interior masters a delicate balancing act expertly – the atmosphere
even in summer is cool enough to create the
mood for down jackets; it is, on the other hand,
so fascinating in terms of clarity and precision
that the brand image is firmly implanted in the
mind of shoppers.

Calling card of an insti­
tution: After dark, the
new main entrance presents itself to the city as
a ­shining glass cube. To
produce this effect, the
designers used uniform
wallwashing inside the
building.
www.ikazia.nl
Get well soon: In a ranking of the 100 top hospi­
tals released by the Dutch daily newspaper “AD”,
the Ikazia hospital in Rotterdam took second
place in 2011. The rating reflects purely the
hospital’s medical merits, yet it scores equally
­highly on patient satisfaction. This may well
have something to do with the fact that great
importance is placed here on architecture and
interior design. As early as the 80s the hospital
began to cooperate closely with the architec­
tural firm EGM based in Dordrecht, one of the
largest Dutch firms with special focus on healthcare facilities. In the 90s, EGM planned renova­
tions and extensions including new wards,
an auditorium and a chapel. The most recent
­building project involved the urbanistic calling
card of the hospital – the main entrance with
the accident and emergency department, both
of which were opened on 31 October 2011.
It is clear how the image of hospital architecture has changed over the last few years:
the new entrance suggests more of a modern
hotel lobby than the dark portals of old hospitals with their linoleum flooring and distinct
smell of disinfectant. Even from afar, the glass
façade grants insight into the foyer; wall surfaces inside are illuminated by wallwashers for
an attractive effect in the dark, creating the
impression of a transparent cube shining from
within. Bright room surfaces not only make for
a pleasant appearance; their high reflectance
also contributes as much to energy efficiency as
does the use throughout of ERCO’s LED recessed
luminaires from the Quintessence system.

Royal rooms with opulent ceiling frescoes,
marble fireplaces, elaborate stuccowork and
polished terrazzo floors – Milan’s Palazzo
­Anguissola at Piazza Scala is a neo-baroque
­palace hailing from the early 19th century. It is
also a prime example of the wealth of historic
architecture worthy of preservation in Italy, a
country with a rich cultural heritage. As luck
would have it, the building today is used as a
museum of art. The Gallerie d’Italia is hosted
here in these rooms as well as in the adjoining
Palazzo ­Brentani – presenting masterpieces of
19th century Italian art from the collections of
the Intesa Sanpaolo bank and the cultural foundation of banking origin, Fondazione Cariplo.
Drawing on a rich stock of thousands of masterpieces from various collections, the gallery’s
curator Fernando Mazzocca ­selected around
200 works for the exhibition. Now, a wider audience can rediscover masters such as Antonio
Canova, Francesco Hayez, Angelo Inganni or
Giovanni Boldini, who were primarily known
better to specialists of the era.
Milan-based architect and designer Michele
de Lucchi and his office aMDL took the opportunity to renovate and redesign the facility. Out
of respect for the building’s fabric, de Lucchi
placed many of the works on movable walls or
stands reminding of easels. Even the lighting
submits to considerations of preserving cultural
heritage; at the same time, lighting designer
Adriano Caputo was able to convince the clients of opting for a future-proof and energyefficient LED lighting solution. The result proves,
once again, just how well ERCO’s LED technol-
ogy integrates even in historic structures while
perfectly performing its functional tasks – alone
and in combination with original chandeliers or
other decorative luminaires. As is often found
in historic buildings, many of the rooms in the
Gallerie d'Italia have all-round stucco friezes at
the upper wall end, ideal for the inconspicuous
mounting of track. In harmony with the room’s
geometry and the exhibition concept, the track
is flexibly equipped with Optec LED spotlights.
Producing different beam characteristics, these
accentuate the works of art, but also ensure
uniform illumination of the decorated ceilings
to provide soft ambient lighting and lend an airy
feeling to the room. In terms of controls, ERCO’s
LED spotlights are usually available either with
DALI interface or for connection to trailing edge
dimmers. Highly efficient LED luminaires thus
offer even more energy savings while providing
the museum technicians with greater scope for
meeting the requirements of both conservation
and scenographic effects.

He knows Scandinavia’s art market like the
back of his hand, but he is just as much at home
in the international art scene – Kaj Forsblom,
founder and senior director of Helsinki’s gallery
of the same name. Since its opening in 1977,
the ­Forsblom Gallery has transformed into
the leading exhibition venue in Finland and a
major centre for contemporary arts in Northern
­Europe. Forsblom represents such well-known
international artists as Julian Schnabel, Tony
Oursler, Joel Shapiro, Günther Förg and ­Stephan

Balkenhol, but draws equal attention to its
forum for Finland’s own art scene. Forsblom
is of course found at all major art fairs around
the world – whether the Art Paris, the Armory
Show in New York or the Art Cologne. Yet the
centre of his art galaxy is and remains Helsinki,
a city voted “World Design Capital 2012” and
increasingly the focus of attention among artists and creative minds. The new premises in
which ­Forsblom opened his gallery here reflect
his standards and ideals – offering exhibition
space of more than 600m2 and accommodating
as many as 500 guests at vernissages, Forsblom
is playing in the Champions League.
These uncompromising standards were simi­
larly applied to the gallery’s architecture. The
new premises are housed on the ground floor
of a prestigious office palace built in 1911 by
Finnish architects Armas Lindgren and Onni
Tarjanne. The monumental building clad in red
granite originally served as the headquarters
of the “Suomi” insurance company. Today, the
dark vestibule of the building opens into a light
28 ERCO Lichtbericht 95
gallery with glass front. Along with a reception
area, offices and storage rooms, it also offers two
exhibition sections. A former atrium was transformed into a high room with natural ­lighting,
followed by a succession of cabinet-style gallery
rooms. The interior design was placed in the
hands of Gluckman Mayner Architects, an office
whose founders are well described as absolute
insiders of the art and gallery scene. The New
York-based firm had already worked with legendary gallery owners such as Larry Gagosian
creating charismatic exhibition rooms and
designed museums including the Dia Center
for the Arts in Chelsea or the Museo Picasso in
Malaga.
To provide a neutral background for the ten
or so changing exhibitions offered by the gallery
during a year, the interior follows the modern
tradition of the “white cube”. Gluckman Mayner
devised a space with extremely reduced detailing and clear, white wall areas complemented
by light Douglas fir timber provided by ­Danish
specialist Dinesen for the floorboards and
the built-in furniture. In terms of lighting, the
interior designers were convinced of ERCO’s
approach to opt straight for future-proof LED
technology as an energy-efficient solution in
museum quality throughout the premises. The
gallery’s lighting concept makes intensive use
of the space-defining effect of wallwashing,
applied in traffic zones, as an example, or to
the back wall of the reception area. The curatorial requirements in the exhibition rooms are
­efficiently and flexibly met by Optec LED spotlights on 3-circuit track. Thanks to the interchangeable Spherolit lenses, the arrangement
and alignment of the spotlights is as quick and
easy as changing their beam characteristic.

The secret to the culinary success of pizza all
across the world may well be its integrative
power – everyone joining in eating the same
thing, and yet the choice of different toppings
ensures an almost endless array of customised
versions to suit every taste. With such versatility, the savoury flat pie soon conquered the USA
as Italian immigrants arrived in the country,
only then to be exported from there all over
the world as a logistically perfected product
of system gastronomy. Today, the Pizza Hut
restaurant chain has more than 11,000 outlets
in 95 countries. The company is continuously
developing new products and concepts, further
stimulating the appetite for pizza. The various new-look test restaurants that have been
opening across England since 2011 are just one
example – the first of these was found in the
Touchwood shopping centre in Solihull near
Birmingham.
Launched with a “Prime Time” motto, the
new restaurant concept was devised in partnership with brand agency Checkland Kindleysides.
Similar to prime time television, the aim was to
see families and friends gather, not around the
TV, but a steaming hot pizza, to share and enjoy
time together. The atmosphere – so the briefing
said – was to be both sociable and stimulating
to encourage patrons to try out more unusual
combinations from the new menu modules.
The consultants, designers and interior decorators of Checkland Kindleysides were extremely
thorough in their approach – taking into
account every point of contact between brand
and patron, from the interior throughout the
restaurant and the design of dishes and cutlery,
right down to staff clothing and the menus.
Particular attention was paid to the lighting in
the restaurant. Once again, the agency’s designers did what they had done for the highly successful concept applied to the award-winning
Levi’s store on Regent Street – they called on
the expertise of ERCO’s retail specialists in the
London offices.
The result is a lighting concept that draws
on abundant scenographic resources, offers a
rich dramaturgy and takes account of all three

functions of lighting as coined by Richard
Kelly – ambient luminescence, focal glow and
play of brilliants. Equally, ERCO’s advanced LED
technology ensures sustainability of the lighting system – based on low energy usage, long
maintenance cycles and correspondingly lower
operating costs.
The “play of brilliants” category involves
the intensive use of projections in the form of
lettering or decorative light patterns to draw
attention. The ambient lighting provided by
Quintessence LED downlights with a mere 7W
in the rooms may be somewhat more low-key,
yet is equally as important. The luminaires’
­brightness level is deliberately muted to ­produce
a strong contrast with the accent light using
a contrast ratio of 1:10. Quintessence LED directional luminaires deliver flexible accent light,
their Darklight reflector ensuring a high level
of visual comfort and, in combination with the
downlights, a uniform ceiling appearance. Also
new in the restaurant concept is “free unlimited
salad with every main course” – the salad bar
appropriately highlighted by a ring of ­Logotec
LED spotlights in spot characteristic. Their
brilliant light with excellent colour rendering
ensures that the food looks fresh and appetising: a demonstration of the high standard of
ERCO’s LED technology.

Swedish Lighting Award 2012 for the
Götaplatsen, Gothenburg
The Swedish Lighting Award is an annual event
arranged by Sweden’s lighting organisations
together with the magazine Ljuskultur. As in
the previous two years, ERCO contributed once
more to the success of this year’s winning project, the Götaplatsen in the heart of Gothen­
burg. The redesign of this square had been
hotly debated in Gothenburg for many years.
Despite the fact that prominent public buildings, such as the art museum and the theatre,
surround it, the space offered little in terms of
appeal as a meeting point or sense of security.
The new lighting concept has changed all that
and has been widely welcomed by the general
­public. A central element in the concept devised
by planning services provider Ramböll ­Sweden
AB is vertical illuminance on the façades as
­spatial borders, generated by Tesis wallwashers
for metal halide lamps. Congratulations to all
involved in the project!
100% LED: New ERCO showrooms
Since the Light+Building trade fair last April
at the latest this much is clear – ERCO has a
range of LED lighting tools that is wide and
diverse enough to implement practically any
architectural lighting concept in impressive
quality. A logical conclusion is, therefore, that
the same slogan that was used for the trade
fair stand should now be applied to ERCO’s
showrooms worldwide: 100% LED. The appro­
priately redesigned first showrooms have now
been opened in such cities as Paris, Frankfurt
and London. They demonstrate vividly what
current LED lighting technology can provide
– whether as spotlights, wallwashers, downlights or varychrome luminaires for ­dramatic
coloured accents. Contact your local ERCO
lighting expert to arrange a visit:

Museum Kunstpalast, Düsseldorf:
El Greco and Modernism
More than 180,000 visitors took the ­opportunity
from 28 April – 12 August 2012 to learn about
the inspiring effect which El Greco as a painter born on Crete around 1541 had on artists of
­early Modernism, before he died in Toledo in
1614. Düsseldorf’s Museum Kunstpalast presented around 40 works by El Greco from major
European and American collections. These works
were placed opposite some 100 creations by
modern artists who had studied the pictorial
world of El Greco: Cézanne, Picasso and Delaunay, but also Beckmann, Kokoschka or Franz
Marc told of their great fascination with the
painter. ERCO’s Logotec LED spotlights played
a significant role in the concentrated, ­dramatic
presentation of the artwork, combining sus­
tainability with qualities that are ideal for the
illu­mination of art.
