1. INTRODUCTION
A museum is an institution which assembles, studies and conserves the objects, in order to set them before public for communication and knowledge supported by them.
The true conception of a museum is an institution with educational uses.
The principle is presentation i.e. to exhibit the objects belonging to the collection.
Visual and tactile experience is used to sharpen the encounter between the object and the observer.
Hence also serve as an inspiration for personal growth.
The success of museums depend on three circumstances:
Firstly, their connection with modern ideas of progress and evolution.
Secondly, their optimistic approach for authenticity.
Thirdly, their aim of reflecting history on basis of documents .
They present natural phenomena, technology innovations and scientific ideas.
The experience motivates children and adults to become more inquisite.

2. ENTRANCE HALL
There must be only one public entrance, placed quite separately from the others.
It should be attractive even to the casual passes and should interest them.
It should provide an easy introduction to the visitor from outside.
There should be adequate museum service zones in which packages are left, guide books, notices are displayed and security checks carried out.
The entrance acts an transition area, they help to the eyes to adapt to the eye level difference.
A social gathering place.
An orientation space.
The size of the entrance hall varies on
The number of visitors.
Architectural expression of the place.
Functions for the space.
Functions of the entrance hall are:
Cloak Room: For placing visitor’s baggage for security reasons.
Enquiry and Sales Counter
Lobby Space

3. EXHIBITION SPACES
The main objective of displaying exhibits is to get their message across the visitors.
The gallery must create an environment conductive for the purpose.
The spatial character of the gallery must provide a spontaneous and unconscious stimulus.
The visitor must be able to have an overall view of the space and should be able to locate himself in relation to some known point.
The general principles considered while designing shall be:
People enjoy surprises and visual excitement.
Change in scale, lighting and layout make the journey short.
People are curious in nature, hence crowds and queue attracts them.
Paths: Routes of movement.
Spaces left between exhibits can be channelised by screens.
Relationship between path and object determines viewing sequence.
Edges: the linear elements and boundaries between paths. An edge defines, separates yet brings out cohesion.
District: points of reference which remain external and unlike nodes are not entered.
May be equally distant objects or small signs that give clue of position.
These are sections which can be grasped mentally, provide pause and make each section more graspable.

4. EXHIBITION SPACES
Nodes: These are focal points where paths converge and these act as a hub of activity.
Pictorial Walk Through: While moving through a gallery or planning door openings, it should be considered that a visual continuity is ensured –as you some out of the gallery, something interesting must invite you.
Giving the Eye Rest: Exhibits in a gallery must be sensitively placed so as to attract the attention of the viewer.
In an observation, the eye stars off at the top and sees everything they can.
Soon they begin to tire and select, in self defense they cease to observe
aggressive colours and strange shapes.
Hence, the familiar shapes like the disc, the ring, the square and the rectangular are easily seen and held in vision.
Hence, to make sure that the visitor does not lose his initial elation, it is essential to have more rest than movement in the general design pattern.

5. EXHIBITION SPACES Pacing :
Pacing is the means of both reducing mental fatigue and physical fatigue.
They result from object satiation, disorientation, lack of contrast as well as discomfort.
Pacing is achieved by:
Visual Relationship of Spaces: Allow simultaneous view of spaces to create a sequence of serial viewing to provide easy orientation.
Relief Areas: If the visitor walks through a number of galleries at a stretch then he tends to lose interest.
Contrast and Diversity of Spaces: Variety in spatial character prevents monotony and stimulates the spirit of enquiry.
After every couple of galleries there should be visual and physical areas to keep the visitor alert for further communication with the exhibits.

6. EXHIBITION SPACES The Viewing:
The first and foremost criteria is seeing
Pacing is the means of both reducing mental and physical fatigue.

7. CIRCULATION
Owing to their communicative and imprehensive nature, visitors can easily acknowledge and comprehend models.
The circulation of a space establish the sequence of its sensed realization.
The space is judge by the flow of impressions .
When in motion one sees a image of series blending into an espanding visual realization of objects, sense and space.
The three main group of circulation are:
Public Circulation: Both for visitors and students.
good and exhibits circulation.
Administrative Circulation.
Ideally the visitor entering the museum should sense the disposition of public services exhibits with minimum help from signs and displays.
Reception facilities should be visible from the entrance and then the architecture should lead the way.
Non exhibits area should be next to the entrance.

8. MICRO-LEVEL
Controlled Circulation :when the exhibits have a story to tell in a definite sequence, the only to ensure that every body sees everything is through controlled circulation.
People are not offered choice of route, it requires careful planning.
This shhould not last more than 100 yards and there should be loosening of layout to avoid the feeling of unbearable consruction.
Each display is carried by every visitor, hence adequate space for stopping and looking must be provided around special displays likely to draw large crowd.
Uncontrolled Circulation: in this public is allowed free choice of things to see.
It may lead to confusion as the visitor may miss out many exhibits.
In children’s gallery , where informal and playful is required , such a layout is suitable.
A good design should ensure freedom for visitors as well as direct them.

9. MODES OF DISPLAY Display is a graphic in 3 dimension.
The arrangement of objects in space, sculptured by light is the strength if displays.
The major modes of display are:
Panels/Screens : Mainly used for 2-D exhibits.
the interactive communication cant be achieved by this mode.
Movies
Models and animation models
Unconventional models.
Display cases.
Model
owing to their communicative and comprehensive nature,all visitors easily acknowledge and comprehend models.
They need to be designed aesthetically to attract the attention of the visitor.
models can be widely used to demonstrate the various facets of science in an interesting manner for young minds.

10. MODES OF DISPLAY ANIMATION MODELS DISPLAY CASES
They are able to capture the attention of the public due to their ability to animate and communicate an application.
They are basically used in exhibiting industrial processes and specula fiction effects.
Though all exhibits can’t be made lucid to all age groups , this mode is effective in communicating in a dynamic manner.
Such models however need specific conditions of environment as well as technical support.
Therefore they are only used for permanent exhibits.
DISPLAY CASES
These are essentially miniature, protected rooms having items meant for display within the confined format of partly or entirely glass enclosed box.
Cases give protection by their showcases.
Theft is made impossible, as it requires forcible entry.
Dust or insects are excluded or minimized.
Local climatic conditions can be controlled or created.

11. LIGHTING NATURAL LIGHTING
In a museum lighting determines how we feel and how we perceive things.
PHYSIOLOGICALLY: the lighting must highlight the object on display.
It must create the right ambience.
There are two types of lighting:
natural and artificial lighting.
NATURAL LIGHTING
Daylight is rarely satisfactory for exhibits as it is too far temperate in cold countries and far too brilliant in tropical countries.
Daylight has daily and seasonal changes with unpredictable patterns depending on cloud cover, atmospheric pollutions and other climatic variations.
Daylight can only be successful in illuminating large areas to stimulate natural external conditions.
However some exhibits need natural daylight like plants, large engineering exhibits and most sculptures.

12. LIGHTING OVERHEAD LIGHTING LATERAL LIGHTING
It provides a steady less liable source of light which least liable to be affected by lateral obstacles.
Wall space is as a result left free for display and exhibits.
However maintenance is a problem.
This type is also difficult to inculcate in multistory.
LATERAL LIGHTING
It is provided either by windows of various shapes and sizes placed at suitable intervals in the walls or by continuous openings
They provide a convenient and economical method of regulating ventilation and temperature.
Acts as an excellent relief by providing pleasant views of the outside natural environment.
However it also causes glare and reflections which impedes the visibility and decreases flexibility of interior layout.
Wall space is also rendered useless comparitively.

13. LIGHTING RIBBON LIGHTING WINDOW LIGHTING CORNER WINDOW LIGHTING
It is a continuous band of window above the eye level on the side extending to the ceiling.
Sun breakers may be used.
WINDOW LIGHTING
Not recommended as reflections and glare where glass is used to protect the exhibits.
Space around the window is rendered useless.
CORNER WINDOW LIGHTING
Glare can be eliminated in this case and there is more freedom in space organization.
MONITORS AND INVERTED MONITORS
Direct light falls on the walls and objects.
Can be used in single storey buildings as the lower floors cannot get top lighting.
Hence, since natural light cannot be avoided, it is best to use it as general light with artificial light over specific exhibits.
It is desirable to have natural light to refresh the visitor’s mind.

14. LIGHTING ARTIFICIAL LIGHTING FLOUROSCENT LAMPS: INCANDESCENT LAMPS:
Ideal exhibition conditions are attained where every aspect of the display is controllable and the light can be focused, moved, colored and all remains independent of weather.
Hence these aspects can be controlled t control interest, mood attention and even pleasure.
It is desirable for an exhibition to have both light and dark areas so that object stand out.
One should be able to achieve light levels to achieve variation in illumination with moderate levels in brightness to connect spaces dramatic and theatrical effects can be sought out by artificial light.
FLOUROSCENT LAMPS:
These are non directional and cannot be focused or used to project a parallel beam.
Reduce glare and used as general lighting.
INCANDESCENT LAMPS:
These are directional and used to highlight on certain spot.
More flexible in use and expensive.
Can be used in conjunctions with reflectors.
