Food
Design Brief
In order to sustain a household during Cmes of disaster design a space to retrofit under constraints of local available resources and a construcCon Cme frame of 10 days to feed two adults (4000 calories daily) allowing for self-‐sustainable food producCon.
Research Different systems a. Roo[op garden b. Indoor gardening c. Aquaponics d. Stacked gardening e. Grey water irrigaCon
Considered a. Soil depth, available space, irrigaCon needs for fruits and vegetables in a hot and humid climate b. The orientaCon towards the sun c. Which types of vegetables can benefit from urine irrigaCon and grey water? d. The types and costs of necessary materials to construct food producCon systems

What did we learn? • The importance of effecCve cooperaCon and communicaCon within and between working groups
• The usefulness of sharing ideas and knowledge and criCquing each other
• The extent of integraCon of plumbing system i.e. the treated grey water for irrigaCon and urine as a nutrient provider for closed loop system.
• How to design and implement a stacked gardening system • Plant types that grow well in hot and humid climate. • Process of planCng. Soaking, type of soil, use of old twigs, leaves etc. as mulch, amount of water and Cme, exposure to sunlight and requirement of humidity for different plants.
Water
Design Brief
To design a water system for a sustainable home built for a family of four. Issues that need to be considered are water harvesCng, storage, pumping, irrigaCon, purificaCon and recycling. A daily amount of 280 litres is needed assuming that each person consumes 70 litres per day.
Research Purifica:on:
Grey water purificaCon (e.g. plants, fish)
Visit to Centre for ScienCfic Research regarding DeWa;s purificaCon system
Tank:
Overhead tank
Ground level tank
ConstrucCon methods (e.g. masonry, Ferro-‐cement, pre-‐manufactured tank)
Rain water Harves:ng:
Roof form for collecCon (e.g. gabled roof, hipped roof)
Plumbing (closed loop circulaCon, green wall irrigaCon)
Pumping methods
Mechanical (e.g. treadle pump, dynamo)
Electric pump

What did we learn? • Teamwork and management • Listening to others • Discussing opCons together • Time management • Problem solving • Researching a topic in depth • Working within a given set of restricCons/constants • Hands-‐on construcCon skills • Cement mixing, pouring, rendering • Tank • Bamboo joinery • Roof construcCon
Energy
Design Brief
Design a cost-‐effecCve, self-‐sufficient energy system for a residence that is capable of conserving as well as harnessing energy in normal condiCons and is able to provide for basic necessiCes in the case of a calamity. The design should be funcConal and realizable within the Cme limit of 10 days.

What did we learn?
• InnovaCon to another level, with ideas such as converCng mechanical energy from the push o a door into electricity! However, in the end we decided to sCck with solar cells, solar cooker and building our own fridge.
• We learned about our energy needs in our daily lives and how much resource is spent in actually meeCng those needs.
• We learned not to give up when things get tough and believe in our ideas and go on even though its not convenConal.
Po;y Poopers
Design Brief
To design a modular sanitaCon system for a retrofit house for two people under the given constraints of money and Cme (10 days) that is efficient with minimum usage of water and energy.

TYPES OF ECO-‐SAN SYSTEMS
Design Process
For its use as a seaCng toilet, we incorporated three steps that would raise the toilet seat to a height of 0.45m which is the standard dimension for a human seaCng posture . also the steps could be used to access the plajorm if people preferred to squat.
Design Process
we also looked into methods of pouring saw dust over the solid waste which would be more efficient and hygienic to use. Thus coming up with a more mechanical soluCon to it.

What did we learn? • Solid waste produces odour when mixed with water.
• Urine is a good nutrient because it comprises of nitrogen and phosphate.
• It is more economical. • Eco-‐ san is more hygienic because there is no handling of unsaniCzed waste faeces.
• Requires low maintainance.
Solar Passive Home -‐ Aria
Design Brief Design a cost effecCve comfortable cooling prototype for 4 people in hot and humid climate condiCon in 10 days that resist calamiCes. The design parameters were: 1. Cost: The prototype should be constructed within the budget of 1,80,000 INR. The total esCmate includes the material and the construcCon cost. 2. Time: The period of the construcCon was restricted to 10days. 3. Labour: The team for the design and construcCon were unskilled 22 people from various backgrounds.

What did we learn? • Importance of available building materials and the cost • Planning and building the structure later, gave us a different
perspecCve • We addiConally gained a lot of respect for builders.
