THE ACADEMY OF ATHENS
OUTDOOR LIGHTING
LiDe 2013
Mathilde Bourbouze – Adrian Fratean – Marcel Neberich
Analysis of the existing lighting
First approach
From the
pavement to the
Academy :
Path
Vegetation on its
sides
Stairs and statues

These elements have been forgotten in the existing lighting design
The façade
Columns are
uplit with Metal
Halide
projectors

Their beam
angle is
adapted to the
columns

The pediment
isn’t lit


These lighting equipments don’t emphasize the pediment sculptures
The entrance
Behind the first
row of column,
there is a
decorated and
colorful ceiling,
which is lit with
CFLs, (CCT
3000K)
•
The back wall
and the second
column row are
not lit
•
The CFLs are placed in the ceiling itself, so it is glaring when we look at it.
Nevertheless it produces a warm and pleasant yellow colour
The sides
The sides of
the building
are less
sculpted than
the central part
•
The upper part
of the wall is lit
with projectors
•
These projectors are too closed to the wall and the beam are not adapted,
therefore the bases of the columns are overlit and the beam doesn’t reach
much of the columns
Analysis of precedents
Museum of fine arts, Budapest, HUNGARY
The elements of
the foreground
(columns, pediment,
basements, stairs)
are uniformly lit

Some shades of
yellow are used

The background
(wall and ceiling) is
lit in a cooler CCT

All the foreground elements receive almost the same amount of light, no particular
part is emphasize.
The foreground emerges from the background thanks to the difference in CCT
US Supreme Court
The elements of
the foreground
(statues, columns
and pediment)
are not lit

Only the wall in
the background is
lit

Only one color
temperature is
used

As the columns on the foreground are not lit, we are looking against the light
when we look at them.
Moreover, we hardly see the details on the pediment.
Parliament, Vienna, AUSTRIA
Same architect as for
the Academy of Athens

The foreground isn’t lit
(columns and pediment)

The background is lit
(ceiling and wall)


Flexible lighting design
As the columns on the foreground are not lit, we are looking against the light
when we look at them, but the warm color invites us inside.
We hardly see the details on the pediment, whereas the painted ceiling is
emphasized
Keeping the best practices





Link the lighting design of the building
with its environment
Use accent lighting to emphasize only
the most relevant details
Choose the source and its beam angle
accordingly to the enlightened shape
Choose the lamp position wisely
Adapt the color temperature to the
application
Proposition of a new lighting design
The permanent installation
The aims

To bring the pedestrian from the
pavement to the Academy

To reveal the beauty of the building

To focus on the entrance
Lighting plan
Tree lighting
•Guide lines
•
Pediment lighting
Ceiling lighting
Gradient of
light on the
façade
•
From the pavement to the Academy
Guide lines
•
Placed in the
ground
With120 Strip
LEDs 6x 1W
having a
luminous flux of
540 lm from
TRILUX
These guide lines are aimed to catch the eyes of the pedestrian walking on the pavement or near
the bus stop. They are lit with strip LEDs, integrated to the ground. This path is dark with a bright
target.
From the pavement to the Academy
Tree lighting
With LED 26 W
floodlight from
BEGA and inground LED 44
W luminaire
from BEGA
Colder light
color 5000K
To create diffuse light we also install some luminaires behind the plants. That is why there will be
subdued light, formed by the leaves of every tree.
The beauty of the building
Pediment
lighting
Wall luminaire
from BEGA with
symmetrical
light having
LED 44 W and
a luminous flux
of 4000 lm
The statues are backlit to make them emerging from the background. Only the
shapes are visible. There is no need for details by night.
Focus on the entrance
Guiding
stripes
With wall
mounted
luminaires from
PHILIPS with
LED 48 W and
a luminous flux
of 2000 lm
Luminaires in form of straight stripes will be installed on the bottom site of the walls to the left and
to the right. They are used to focus on the entrance and to guide through the area.
Focus on the entrance
Columns
lightened from
the front with
in-ground
luminaires
having
asymmetrical
light distribution
with halogen
100 W
To fulfill the concept in a whole, in this part the brightness of the columns
increases to the middle. The luminaires are located in front of the objects to
make this difference visible.

Proposition of a new lighting design
The temporary installation
The aims

Create an attraction in front of the Academy

Bring people from the pavement to the building

Highlight the change in lighting design

Reveal an interesting detail of the site
Temporary Installation
A reactive
installation
•
Use of a
motion sensor
•
At the time when a pedestrian is nearby, a motion control will switch on some
text to make them rest for a couple of seconds.
Temporary Installation
Up-lighting the
statues from 3
(2 permanent
& 1 temporary)
directions with
in-ground
luminaires
mounted in
front of them
and with LED
projectors from
lateral
…after the pedestrians are stopped, the text will disappear. In addition all of
the four statues, looking at this place will be up-lit.

Technical data

Total luminous flux: 609794 lm

Total electrical load: 10581 W

179 luminaires from 2 manufactures

DALI controlled lighting
Conclusion

2 lighting installations :

A temporary, to create an attraction

A permanent, to highlight the beauty of the building

Aimed at drawing the attention on the Academy

Using new technologies...

…While respecting its neo-classical style
And for further improvements…



Add flexibility to our lighting design, to enable
different lighting scenarios
Design a lighting solution for the sides of the
building, avoiding the degradations
Take into account the other 2 buildings of the
Trilogy, in order to design their lighting as a whole
Thank you for your attention!
