The document discusses various techniques for lighting building facades at night. It begins by explaining how lighting can give buildings a new identity and personality after dark. Different lighting methods like flood lighting, accent lighting, and dynamic color lighting are described. Considerations for the design of facade lighting include emphasizing the architecture, attracting attention, and conveying emotions. Proper lighting enhances visibility and safety while highlighting distinctive architectural features. The techniques discussed can transform how buildings appear and are experienced at night.

• Anarchitecture’s nighttime “personality” maycreate anentirely new sense of placefor abuilding,

5. • Overthepast 100years electric light has
completelytransformed thepublic realm.
• Beginning withtheillumination ofthe Eiffel
Tower atthe1889World Exhibition inParis,
lighting enabled aneven greater
monumentalityfor such landmarkstructures
andbuildings.

6. • Modernarchitecture, withits large expanses ofglass,redefined a building's interaction wit
its surroundings.
• Windows,whichlet naturallightinside by day,at

Kerry Centre, Shanghai
Architect: Kohn Pedersen Fox, New York
Lighting Designer: Tillotson Design Associates, New York
•The main challenge was how tocreate a sense of
brightness and sparkle that would read both up close
and from adistance without the disturbance of a lot
of glare.
•The façade needs towork both during the dayin
natural lighting conditions and atnight when the
panels are illuminated bytwodifferent grazing
fixtures located atthe top and bottom of the entire
assembly.

•The first fixture typesare 10-
degree 4000KLED grazers that
illuminate the top front,the
bottom front,and the bottomback
of the panels with white light.
•The second are RGB LED
luminaires with a medium beam
distribution that create color-
changing effects, and which sit
behind the bottom grazing fixture.

• Structuring architecture
Light lines define structure and
allow easier orientation :
• The architecture and contours of a
building are visible, even when it is
dark
• Different luminance levels on
various surfaces differentiate the
foreground from the background

15. Emotional lighting
How Building looks different at night :
– Static or dynamic lighting scenarios using colours
replace traditional accent lighting
– Creative lighting patterns and textures reinforce
emotional connection to the building

20. • Thedesign oflighting for an architectureis critical —as
this illumination is what makes it work for nighttime use.
Throughaspects like :
• 1- Hierarchythroughlight intensity
• 2- Materiality throughlighting color and even the useof
lighting direction (with conscientious useofshadow),

21. • 3 -Lighting fixture technologies :
mustworkwell withabuilding’s elements during daylighthours. Thus,selecting proper lighting
is simultaneouslyaboutintegrating beautifullighting fixtures as it is aboutmakingsure those
lighting fixtures present thearchitecture at its fullest potentialat night.

22. Basic consideration that must be taken when designing the lighting of the facades :
- installation methods : must be easy
- does not spoil the overall look of the building
- Power & contact points
- possibility and ease of maintenance in future safety of use
- flow direction

23. Main techniques of facades lighting :
General flood lighting : -
the easiest option of lighting. It is ideal for cultural objects (monuments and churches),
stand-alone facilities, because the grandeur of preservation and holistic visualization. Flood
lighting is characterized by the installation of lights at a certain distance from the
illuminated objects - they are often mounted on poles. But you must keep in mind that the
light aimed at the building will pass through the window, so this kind of lighting is
undesirable for use in buildings that will be full of people at night ( houses, malls, hotels)

The Lincoln Memorial

24. The historically sensitive lighting system used for the relighting of the Lincoln Memorial
brings out many of the Memorial’s long-hidden details, and ensures that the statue of
Lincoln is highly visible. In addition, great care was taken in the lighting of the historic
murals on either side of the inner chamber to allow visibility of the murals without light
levels that would damage the delicate material. The final result is a re-illuminated
Memorial proudly and beautifully

25. Focus Attention to interface elements (window frames, arches, cornices, columns ,balconies) .
In order for the composition to be harmonious, all items must be luminous and skillfully
connected to one composition. In this incarnation, architectural lighting used medium, low-
power lamps and linear shape lighting on the basis of light-emitting diodes. These bulbs are
nowadays becoming increasingly popular
Architect Edward Said explained that the approach appeared to light historic buildings so
as to highlight specific features while leaving others dark.

26. It is a kind of artistic effect, allowing to achieve the shape of the image outline of the object,
but without any details. That is, the silhouette of the object shows the creation of a luminous,
black or dark background ( the essence of the effect) . This creates a clear image and powerful
graphics, and applies a similar effect to highlight the palaces with columns and theaters.

27. Suitable for lighting Modern buildings with fully glazed( shopping and entertainment
centers, office buildings) .
The lighting equipment is installed indoors and draws on the glass - produce a variety of
lighting effects: fixed or variable.
TOD`S

28. A relatively new technique when the perimeter of the building stands out with the help of
linear lighting.
This collective implementation of contour lighting was made possible by the advent of
inexpensive light sources ( flexible neon and LED bars) . They are installed on the front of
hundreds of meters, for example, they illuminate the corners of the cornices

29. A lighting method that use color synthesis
Changing the colors within a certain time and increasing / fading brightness. But the methods
of systems tsvetodinamicheskih application can be anything: fill, tone, imagination. It uses a
variety of tsvetodinamicheskie lighting: floodlights, LED bars and lights.

30. GLARE AND SHADOWING
On the design side, luminaires
strong glare and shadowing can be
problematic. An issue that
manufacturers responded can be
fixed by switching from Device On
Board (DOB) to Chip on Board
(COB). Wallace projected future
lighting trends will include the
gradual replacement of SMT to COB
to reduce shadowing.

31. COMBINING TECHNOLOGY WITH THE RIGHT LOOK AND FEEL
Retailers can’t compromise on
the look and feel of their shops,
and that still presents a
challenge with new lighting
technology. As Dean Laurent,
utilities purchasing manager at
Arcadia, points out: ‘The
customer comes in for the
product, not the lighting. We
need our stores to be bright,
young and we do not want to see
new technology make them
duller.’

32. LACK OF COLOUR AND STANDARDARIZATION MEASUREMENTS
Lack of LED industry standards for Color
Correlated Temperature (CCT) and data
presentation also continue to trouble designers,
when it comes to picking the right bulbs for
projects.
Designers also face difficulties in sorting out
lighting label measurements as manufacturers
use different benchmarks and measurement
criteria. Wallace also pointed out there is currently
no design tool for LEDs and it may take another
four to five years to develop one.

33. THE NEED FOR THERMAL MANAGMENT
The good news for designers is
manufacturers are increasingly
able to control heat dissipation
as LED efficacy improves.
Higher efficiency has resulted in
less heat loss, and make
products better suited for hot
climate applications.
Technological advancements
have enabled innovations in
LEDs that now enable heat sink
free bulbs

34. ENHANCE THE LIFECYCLE OF THE PRODUCTS UDED
Manufacturers of commercial and
industrial lights are faced with
many of the same challenges
seen in the residential market.
Lighting designs must be
functional, attractive, and
lightweight while also delivering
high optical efficiency and light
uniformity and resist the
weathering forces to stay on
service as long as possible .
Examples of different light pulps and their
different service abilities .

35. ACCOMPLISH GOOD BRIGHTNESS AND HIGH OPTICAL CLARITY
In outdoor applications, brightness and high optical
clarity are also critical success factors. While glass
and PMMA achieve higher light transmission,
continuous advances in PC materials have all but
leveled the playing field. At 2.5-mm wall thickness,
improved-clarity PC materials can provide
approximately 90% light transmission, on par with
high-heat PMMA and 2% behind standard PMMA.
