INTRODUCTION
o This presentation looks into the lighting design for spaces
and its effects in architecture.

o Lighting in a space is a positive force that can motivate

people to be active, relaxed, productive, lively, depressed,
fearful or overactive.

o Lighting provide visibility, character and mood as well as

relate harmoniously to the space in which it is used.

o Materials & interiors are never shown to their fullest without

a good lighting scheme behind them.

o lighting design can be one of the most creative area of

architectural design.

INTRODUCTION
WHAT IS LIGHT…?
Light is a form of radiant energy (Electro Magnetic Radiation) which is visible to
human eye and responsible to the sense of sight.
Lighting within the indoor environment can be considered to have three basic
purposes:
• To enable the occupants to work and move about in safety.
• To enable tasks to be performed.
• To make the interior look pleasant.
There are two principle ways in which a building can be lit :
• Natural Light
• Artificial Light
Natural light is the light generated naturally. The most common source
of natural light on Earth is the Sun.
Artificial light is generated by artificial sources, such as incandescent lamps,
compact fluorescent lamps (CFLs), LEDs, etc.

NATURAL LIGHTING
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.
• 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. Source : elemental.green.com

 architecture
• Light is as much a "building material" as steel or concrete.

• Although such structural components are needed to enclose a space, it has no

real existence for an individual until it is seen and it registers in his
consciousness.

• Light defines space, reveals texture, shows form, indicates scale, separates
functions and Creates mood.

• Good lighting makes a building look and work the way the architect intended at
all hours of day and night. It contributes to the character, to the desired attitude
toward form and space, and to the effective functioning of that space.

• Lighting is dynamic. Change the lighting and the world around us changes.

• Light can make or break a space both functionally and aesthetically.

 LIGHTING DESIGN CONSIDERATION
The factors that should be considered in lighting any space are:

• The most important factor in a space is the people who will occupy it,
use it, live in it.

• The SITUATION

• The FUNCTION

• The QUANTITY AND QUALITY OF LIGHT needed to perform tasks

• The ARCHITECTURE and DECOR.

• The ATMOSPHERE or psychology of the space.

• The RELATIONSHIP to adjacent areas.

 PLANES OF BRIGHTNESS
When brightness occurs in a space establishes the character or
mood of that space.
• A ceiling left in shadow creates a secure, intimate, relaxing
environment suitable for lounges, leisurely dining and board
rooms.

• High brightness on the ceiling creates a bright and cheerful or

efficient and work-like atmosphere good in coffee shops,
classrooms and kitchens.

• With the ceiling in shadow, brightness on the vertical planes of a

space draws attention to the walls, expanding space visually; good
for galleries, merchandising, lobbies.

• A pattern of varying levels of brightness can indicate direction and

lead people through a space.

 LIGHT AND SHADOW
• Highlight provided by accent light creates focal
points that can direct attention or communicate an
idea.

• A lighting scheme should not be so exciting as to

overwhelm or destroy the interior design, nor so
placid as to make a room dull and uninteresting.

• Free standing objects, such as sculpture, lighted

from two directions with different intensities or tints
of color will appear fully three dimensional.

• Shadows are essential for perceiving dimensionality.

• Three dimensional objects lighted from directly in

front appear flat, but when lighted from the side,
assume depth and roundness.

 KINDS OF LIGHTING
AMBIENT LIGHTING :

• Ambient light means the light that is already present in a

scene, before any additional lighting is added.
•
• It usually refers to natural light, either outdoors or coming
through windows etc. It can also mean artificial lights such as
normal room lights.

• Can brighten and enhance the glow of the rooms.

• Lanterns and wall fixtures can render an ambient lighting

effect.

• Using dimmer switches can also change the ambiance of the

room to achieve the desired look and feel.

 KINDS OF LIGHTING
TASK LIGHTING :

• Task Lighting refers to increasing illuminance to better

accomplish a specific activity.
• Task lighting is one of the most important elements of
commercial lighting design. Its point is to provide the
necessary illumination for the worker to perform their
task.

ACCENT LIGHTING :

• Accent lighting focuses light on a particular area or

object. It is often used to highlight art or other artifacts.

• Accent lighting is an important lighting element for the

architect for it allows the right emphasis of a design
element or detail that can enhance or underscore a
theme or essence of their design.

 DAY LIGHTING
• Day lighting is the complete process of designing buildings to
utilize natural light to its fullest. It includes all of the following
activities.
• Always a better source of light with good color rendering
property
• Saves electricity
• Sitting the building—that is, orienting it for optimum solar
exposure
• Massing the building—that is, presenting the optimum building
surfaces toward the sun.
• Choosing fenestration to permit the proper amount of light into
the building,
• Taking into account seasons, weather, and daily solar cycles
• Shading the façade and fenestration from unwanted solar
radiation
• Adding appropriate operable shading devices, such as blinds and
curtains, to permit occupant control over daylight admission .

 AGi32 version 18
INTRODUCTION
• AGi32 is a computational program that performs
numerical point-by-point calculations of incident direct or
reflected light on any real surface or imaginary plane.
Within this scope, it is used to predict or quantify the
distribution of artificial or natural light in any
environment.

FEATURES
• Provides comprehensive lighting calculations, ease of
modeling, and fast, high-quality rendering for almost any
interior or exterior environment, including Daylighting.

 AGi32 version 18
MODELING
• Capable of constructing almost any architectural
environment. Vaults, domes, curves, slopes and
extrusions are easily created, allowing you to
accurately model the architectural elements you
encounter every day
• It can import 3D geometry via DWG, DXF and
through our LAI Data Exchange (LaiDex) as
exported from or SketchUp plugin.
RENDERING
• AGi32 can be used to generate extremely fast and
photometrically accurate color images of the
behavior of light within the environment.
• As the rendering engine is fast enough to be used
on an iterative basis, designers now have the ability
to quickly visualize and share different lighting
scenarios before they are specified, purchased and
installed.

 AGi32 version 18
CALCULATIONS
• AGi32 has two calculation methods to assist with the
computation required in the most efficient manner.
FOR EXTERIOR
For strictly numeric results in an exterior parking, floodlighting,
or roadway application, AGi32 has an extremely fast direct
component calculation engine. The Direct Only calculation
method will consider the shadowing effect of objects in the
scene and produce point-by-point illuminance on any surface or
plane in space.
FOR INTERIOR
For interior or exterior projects where inter reflected light is
important, AGi32’s Full Radiosity calculation method will
compute the interaction between light and surface using its
state-of-the-art calculation engine. In this mode all surfaces can
be assigned a color and reflectance and accurate luminance
levels are computed for the entire environment. An interactive
light-accurate rendering is produced automatically.

BACKGROUND IMAGES
AGi32 can import a series of JPG or PDF images to be used as a background for your lighting work. The images
can be scaled, seamed together and faded to show underneath your lighting layout and calculations. This is
immensely powerful for retrofit work as images can be captured in seconds from Google Earth
