7. Introduction
▪ The perception of space is directly
connected to the way light integrates with it.
▪ What we see, what we experience and
how we interpret the architectural elements
is affected by lights.
▪ Regarding architecture, either as space, as
material or as color, it is essentially
dependant on the lighting situation.
▪ The dynamic daylight and artificial lighting
are able to instigate and provoke different
visual experiences and moods.
▪ Due to the light, it is possible to perceive
different atmospheres in the same
physical environment.

8. What Is Light?
▪ Light is the soul of architecture design.
▪ Light allows us to see, to know where we
are and what around us.
▪ Light models those objects to enhance
visual and to help us define the physical
world.
▪ Nothing would be visible without light.
▪ To redefine the relationships of people
with the environment and with themselves.
▪ It is divided into natural light and artificial
light.
▪ Natural light is a gift of nature.
▪ Artificial light sources free people from
total dependence on daylight during the
day as well as after dark.

9. Relationship Between Light, Space and
Human
▪ Light is fundamental for space and essential for
human well-being and it is the success of any building.
▪ Light quality affects human behaviour, health, comfort
and mood.
"Space and light and order. Those are the things that men
need just as much as they need bread or a place to sleep"
- Le Corbusier
▪ Light, space and human they effect and work with each
other.
▪ Space needs light to illuminate; light needs space to
receive it, light within the space change human
experience.

10. Relationship Between Light And Architecture
▪ Most of the architectures like to amplify use of
natural light.
▪ Natural light makes architectural more
harmony between exterior, interior, nature and
human.
▪ Light work with some element like colours, can
make space more dynamic and beautifier.
▪ Vision is most important sense through which we
experience architecture, and light is the medium
that reveals space, form, texture and colour to
our eyes.
▪ Light can be employed through design to evoke
an emotional response to increased sensibilities.
▪ Architecture and light have close relation.

11. Natural Light And Architecture
▪ Natural light keeps changing through
times.
▪ Architects cannot control natural light, from
morning to night, day after day changes.
▪ Its existence gives life to space, modelling
the spatial sensibility.
▪ Natural light for the space, like the air for
life, these two have symbiotic relationship.
▪ Natural light into interior design have many
positive effects, including the considerable
financial savings in energy.
▪ Natural light is considered a beneficial
design for many reasons: human health,
comfort and satisfaction, energy
conservation, view. 11

12. Light Influence Mood
▪ The psychological
factors should not
be overlooked.
▪ People need to
change
perspective in
order to relax the
eyes and mood.
▪ Lack of natural
light makes
people feel
depressed and
tensed

13. Light Create Atmosphere
▪ Light creates atmosphere.
▪ Many factors affect the building
atmosphere.
▪ Natural light is one of the most important
factors.
▪ Architect needs to use light to create a
different order and rhythm change the
spatial effect gives different atmosphere.

14. Natural Lighting
▪ Lighting or illumination is the deliberate use of light
to achieve a practical or aesthetic effect.
▪ Lighting includes the use of both artificial light as
well as natural illumination by capturing daylight.
▪ Daylight as two distinct sources of light:
▫ Sunlight – That part of solar radiation that
reaches the earth’s surface as parallel rays
after selective attenuation by the
atmosphere.
▫ Skylight – That part of solar radiation that
reaches the earth’s surface as a result of
scattering in the atmosphere.
▪ Sunlight and skylight may therefore be considered
as the direct and diffuse components of daylight.
▪ Day lighting is sometimes used as the main
source of light during daytime in buildings.
14
15. Daylight
▪ Daylight, or the light of day, is the combination of all direct
and indirect sunlight during the daytime.
▪ This includes direct sunlight, diffuse sky radiation and
(often) both of these reflected from the Earth and terrestrial
objects.
▪ Daylight (both sunlight and skylight) is usually admitted into
a building by the means of windows and skylights.
▪ The quantity of daylight obtained within a room will be
dependent upon:
▫ the orientation, geometry and space planning of
the spaces to be lit.
▫ the location and surface properties of any internal
partitions which may reflect and distribute the
daylight.
▫ the location, form and dimensions of any shading
devices which will provide protection from too much
light and glare.

16. Lightwell
▪ Light well or air shaft is an unroofed external space
provided within the volume of a large building to allow
light and air to reach a dark or unventilated area.
▪ Lightwells may be lined with glazed bricks to increase
the reflection of sunlight within the space
▪ Lightwells serve to reduce the necessity for electric
lighting, add a central space within the building, and
provide an internal open space for windows to give an
illusion of having a view outside.
▪ Use of the light well was known in ancient civilizations,
including Egypt and Romans at the Palace of Knossos on
Minoan Crete.
16
17. Clerestory Windows
▪ Another important element in creating daylighting is the
use of clerestory windows.
▪ These are high, vertically placed windows.
▪ They can be used to increase direct solar gain when
oriented towards the equator.
▪ When facing toward the sun, clerestories and other
windows may admit unacceptable glare.
▪ Clerestories can be used to admit diffuse daylight
that evenly illuminates a space such as a classroom or
office.
▪ It also shine onto interior wall surfaces painted white or
another light colour to reflect indirect light to interior
areas where it is needed.
▪ This method has the advantage of reducing the
directionality of light to make it softer and more
diffuse, reducing shadows.
17
18. Skylights
▪ Skylights are light transmitting fenestration
forming all, or a portion of, the roof of a
building space.
▪ Skylights are widely used in daylighting
design in residential and commercial
buildings
▪ An alternative to a skylight is a roof lantern.
▪ A roof lantern is a daylighting cupola that
sits above a roof, as opposed to a skylight
which is fitted into a roof's construction.
▪ Roof lanterns serve as both an architectural
feature and a method of introducing natural
light into a space, and are typically wooden
or metal structures with a number of glazed
glass panels. 18

19. Atrium
▪ Atrium is a large open space located within buildings.
▪ It is often used to light a central circulation or public
area by daylight admitted through a glass roof or wall.
▪ Atrium provides some daylight to adjacent working
areas, but the amount is often small and does not
penetrate very far.
▪ The main function of an atrium is to provide a visual
experience and a degree of contact with the outside for
people in the working areas.
▪ The daylighting of successive storeys of rooms adjoining
an atrium is interdependent and requires a balanced
approach.
▪ Light from the sky can easily penetrate the upper storeys
but not the lower, which rely primarily on light reflected
from internal surfaces of the atrium such as floor-reflected
light.

20. Is Natural Light Better Than Artificial Light?
▪ Using as much natural light in interior
spaces as much as possible has many
advantage over using artificial light.
▪ Artificial light is unable to replace
some effect of natural light.
▪ Natural produces positive effects,
both physiological and psychological.
▪ Making good use of natural light cuts
the need of artificial lighting and
energy consumption as well as helps
provide a feeling of well being to our
everyday life.
