Providing contrasts and diversity in spaces so as to hold visitors interest.

Easy organization and layout of spaces for easy orientation.

Provision of rest areas to change of pace activities.LightingLighting is of primary importance in visual oriented buildings like museum.The following guidelines may be followed in creating luminous environment. Theamount of light to view exhibits in less than to perform tasks. Both daylight andartificial light must be taken into account. Colour temperatures must beconsidered and need for natural light must be explored.Qualitative aspect of light must be considered, glares should be avoided.Natural light must be controlled by using louvers, blinds etc, use of high levellighting for even light and more display diffuse. Point source of artificial light cancreate exception glare, hence careful choice must be done(most applicabletungsten halogen and florescent). Design Thesis- ILLUSION MUSEUM Data Collection 27Even in well day lit room electrical lighting is to be used on winterafternoons when daylight fades. When side lit room deep enough for workrequiring luminance 500 to be carried out at a distance from window greater thanheight of window head above working place, electrical light required for more than15% of the working year as day light factor will probably be less than 10%. Iftinted glazing is used these depths are greatly reduced. Therefore the generallighting luminaries should be arranged in rows parallel to window wall and eachrow should have separate switches. The switches should be located so that theycan be conveniently operated by occupants. Florescent lamps should be chosenfrom intermediate colour range compatible with the colour rendering requirementsand with warmth of lighting required at night.For maximum conservation if energy automatic control should be installedin a new building to switch off or preferably dim those rows of luminaries lightingthe work areas which are not required when daylight rises to provide luminance atthat depth such that full electrical lighting is not necessary. In top lit interiors withsufficient glazing to provide an average daylight factor of 10% over working yearfor tasks on which 500lx required and for longer than this where higher luminancerequired or DI provided. The whole installation can be linked to a photo electricswitch or photo electric dimming contol where florescent lighting is used.Different methods of admitting natural light from above.

The system which is flexible and gives large unobstructed spaces should beadopted in galleries.

Easy integration of services such as air conditioning ducts, lighting fixtures andfans should be there.

The building should be secured against vibrations, damp rising from ground,fire and theft etc.
