Water – Rainwater harvesCng

Energy – Solar PV InstallaCon

Po;y Power – Ecosan Toilet

Home – Solar Passive Home

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

Design

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.

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

Design Process

ImplementaCon Materials •  Bamboo (split and wound in a basket) •  Chicken wire (for reinforcing the cement) •  Cement •  Jute (for tying bamboo together) Construc:on •  Bamboo frame for base •  VerCcal bamboo posts weaved through base frame •  VerCcal posts li[ed and Ced with jute •  Chicken wire fixed on interior and exterior of basket •  Concrete base poured (basin shape for basket to rest) •  Cement hand-‐ rendered onto chicken wire to form Ferro-‐

cement

Building

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.

Energy Audit

Hands-‐on Building

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.

Hands-‐on Building

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.

Hands on building

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.
