intro : the aim

An emergency or a disaster come without an invite and leave the household shattered. Some times it can be resisted many times cannot, with that in mind a disaster shelter has two factors essentially bound to it, time and deployeablity. Besides these as a designer we would like to highlight a slight human centered approach where parallels can be drawn between these functional as well as well psychological aspects during the design of the shelter. The following product is derived after addressing these domains. Key Domains: Ergonomics / Psychology / Disaster Residence / Economy / TIME

psychology

catastrophe

In a disaster situation, an individual is a has to contain trauma as well as deal with important survival decisions. Split with loved ones, destroyed home, shattered lives, chaos all around, are just a few ways describe this suffering. The person is in the most -ve situation, and most crucial choices / challenges thrown, a shelter is a means to ease this out and shall be built over this mind set in head.

A catastrophe on the hand is a matter of seconds, sometimes it comes with a warning. Many times it doesnt. It might come in series so that response help may get caught in, or a resource pile could be struck which leads to delayed supply.

V/S

In addition to this, the aged, women and children are the ones who need alot of care, and protection, so the design should be in response to these users also. (Lowest first principal user)

Key takeaways: Transition, Less time, Disturbed, Crucial decisions, Bare minimum, Lost, Helpless.

Key takeaways: Series, No warning, Supplies could get deteriorated, Simple, Used/Setup by All.

inferences

On the above debate the following inferences are generated to be taken as design guidelines and considerations. Reliance over site.

User friendly.

Reduce hazard.

Basic needs first.

Creating colonies.

Cultural Aspects.

the built

As we move on, its quite clear that none of the above work in a similar fashion. Preparing for an after disaster situation, leaves very little or no available resources and most of them have to sourced from a distance where are response team is available. Hence, ergonomics as well as portablity are an equal challenge as well. The process works in devising a practical configuration at first, which can be fabricated in three phases, essentials only, stable shelter and a permanant structure if required. The design process evolved out of trial and re trials,

experimentation

The below selected forms are a result of constant shortlisting and selection in terms of form finding with practicality terms of the emergency shelters. The parameters are listed below for comparison.

climate + re-useablity

Climate resistence, increases the cost at the same time bulk value of the overall setup. The aim should be adequate and not all luxuries. Hence the consideration is partially done as per priority. The dealing can also be shouldered with site and it is in an essential part in survival scenario.

structuring

permutations + combinations

On the structural part the three resolving patterns were considered and it was found that to reduce the package size, only requisite necessary materials shall be the part of primary relief.

The permutation has an economic as well as configurational attribute attached to it. A highly configureable model might get costly so, preffered outcomes would be satisfying towards both.

bulk The shell hence is not a priority shelter requirement and be procured to the site on the latter run or as per catastrophe.

STAGE 4 Hereby, the final configuration hence is developed in a 2x2x2 fashion to have a same size of component and higher degree of flexiblity and multiplicity. It also ensures sharing of supports and nodes that make the whole colony more stable and reliant on each other for setting up. CONFIGURATION

All the jugglery above, culminates into a design that has a configurational aspect relinked again with practicality and economical stature. The design has to be simple so the cube might not be the most stable form to work with but yes it is easy, it is most functional. A box, A home, An enclosure, best defined. Upgradeablity is also an important aspect too, as these shelters shall be adapteable to various situations. Apart from that use of site as a shouldering element which is a SHEET 1

development

Roof Options

The tarp shelter can be modified using on site material and debris to make enclosure more safe and strong + basic climate resistence.

The following options are in a conceptual idea, to devise other components via on site or by accessories. The usage can vary from site to site but ultimate aim is to show replicablity and adaptivity.

Bow arch type.

Inclined beam type.

Skeleton + Skin + Site (S3A)

In this case if the skeleton is only procured to the site then, there’s skins can be arranged on site this way. This is substandard but one of the most primitive alternatives.

Basic climate resistence + Essential only features.

Skeleton + Skin (S2A)

The following structure uses tarpoline and aluminium fram to create a suitable enclosure for shorter time period. Not applicable to heavy snow areas.

The basic building block of the shelter, the primary skeleton can lead to many possiblities and aims to solve the basic needs of stability and enclosure in a catastrophe scenario.

Skeleton + Shell (S2B)

This shelter is an advanced prototype of the same shelter, with 2m x 1m panels of wall roof or floor systems, as necessary. Design can be variable and mostly intended to procure when things are under control.

A colony is visualised in such a manner where the survival is sparked amongst people who live and share together, colonies have optional and multi configurational ways to make a small rehab settlement. SHEET 2

a spirit of survival together

The best form, in terms of functionality and packing efficiency but lacks the simplicity of a disaster struck man.

A configuration of interdependent shelters, infuses a feeling of dependence, and responsiblity towards one another. It can also be seen that planning can be extremely random, but each shelter owner has to have an access and a ventilation which drives the colony. In addition to these the same shelters can be used to create linear forms of colonies as well. Configurations / Permutations / Adjustments / Accessories, the following proposal is an exploration towards incremental shelters.
