SCIENTRIUM: SCIENCE MUSEUM
Academic Project: Undergraduate Research based Design
Individual Work Teachers: Ar. Simroz Khan, Ar. Sourabh Gour
The aim of this study was to analyse the light pattern in Indore, Madhya Pradesh, India with composite climate and determine effective and comfortable daylight penetration in tropical composite climate of India and designing a science museum with optimised daylight penetration.
The building complex was conceptualised keeping in mind disability discrimination and thus ramps as the only way for vertical circulation were idealised.
Creating boxes according to required volume
Other than providing ‘disability equality’, the ramps have various functions:
2. Deviced to provide shading to fenestrations in exhibition halls
1. Acting as a ‘buffer’ for exhibition rooms to minimise sun heat.
3. Glass walls allow the view of whole site while walking through.
Green Roof
Louvres to allow light in emergency stairway

central public space Arranging the boxes to create smooth circulation Undergroud Auditorium
Lifting boxes to allow wind circulation
Adding ramps and lifts for circulation
THREE LOBED TORUS
Academic Project: Topology Problem
With: E. Galata, J. Robinet Teachers: E. Soriano, G. Bertmeu
Rationalisation
Periodic curve on the discrete mesh, mesh is further subdivided to make stripes,
Detailing
Stripes from periodic curve, splitting curve according to the angle between consecutive faces.
Joining create
smaller stripes to longer stripes.
Nesting
Interlocking flaps for easy assembly, no stapling needed. Stripes start and ends are named by numbers. 1-2, 2-3, 3-4 etc. Ends with the same number connect: 1-1, 2-2, 3-3. Stripes are also named sideways along 4 periodic stripes: B1-B2, B2-B3, B3-B4. Sides with the same name connect: B1-B1, B2-B2, B3-B3.
104 stripes - 42% waste, 6 sheets of 35*96 cm. Total assembly time: 2h 30min.
