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.

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.
