Concept

Cattle Care Sanctuary

Government of Gujarat is contemplating to establish world's first unique cow sanctuary in Gujarat - near Porbandar .

However the Sanctuary that are funded are mainly for the specific breed of the cows, but in the cities the cows have a very different stories, these are the abandoned cows, that serves no direct purpose.

•

It removes the cattle from the road by providing a healthy space for them.

•

A specific space for the people to dump their food waste, thus a natural waste segregation happens over to some extend.

•

The people who wants to feed the cows out of their religious believes now have a specific place to go rather than look go around the city in search of the cows.

•

The Cow Dung collected at the Sanctuary will be used at the Bio Gas plant that serves the fuel to the community Kitchen.

•

The Manure from the Cow Sanctuary will be used at the rooftop organic farming by the families.

In India their are many Aashrams and NGOs providing the shelter of the Abandoned animals, Goshalas, are specially for the Cows due to its Holy Mythological Connections.

Bio Gas Plant

In 2014-15, about 20,700 lakh cubic meters of Biogas is produced in the country (INDIA) which is equivalent to 5% of the total LPG consumption in the country.

•

Biogas Plant will cater fuel to the Community Kitchen to prepare food.

•

Reduce the cost of the production

•

Raw material for the biogas will be taken care by the cows from the cattle sanctuary.

•

Surplus Energy will be consumed by the community

•

The presence of the odour of the cow dung keeps the Mosquitoes away form the environment that reduces the risks of the many diseases. the government of India had set a target to set up 6.5 lakh biogas plants across the nation with a budget of Rs.650 crore under a program called, the National Biogas and Manure Management Program

Community Kitchen

Community Kitchen

Amenities in the area

•

The organic food station for the community

•

The vegetables for the kitchen is fetched from the rooftop farming, where the food is grown organically

•

Catering the food to the nearby Hospital and the elementary schools

•

Behavioural Changes Intervention and Measure  Waste management

School Hospital Bank

 Community Interaction  Reducing the women work at the home •

Healthy and Hygienic food

Community Kitchen- Research

• USA : Soup Kitchen •London : Food Bank •South America : Community Kitchen •India : Langar (Sikh Worship Place Kitchen) - Amma Canteen : Tamil Nadu -Zenkhar Bakhar :Maharashtra - Janta Aahar : Delhi -Aam Aadmi Canteen : Delhi -Daal Baat Kendar : Chhatisgarh, Jarkhand - Guthuk : Ladakh -Bangladesh : Bhoj

Examples from across the globe Community kitchen are popular all across the world and cater services with different motivations and works in different ways, though it works mostly for the serving the hunger and homeless population, where the state funds such programmes.

At the same time it also increases the community interaction, provides job opportunities, as well as ease the workload of the women at home beside providing the healthy and hygienic food.

Rain Water Harvesting •

Harvest 100% of the rain that falls on the building.

Kerala houses some 4.5 million open wells, the largest density of open wells for any place in the world.

Advantages Surat Municipal Corporation has made Rain water harvesting mandatory for new buildings with plot size of 4000 sq. meters or more. 50 % subsidy maximum amount up to Rs. 2000/- is given to the citizens.

Gujarat: Under the Gujarat Development Control Regulations, buildings with area between 500 and 1500 sq. meters, the owner or developer shall have to undertake Rainwater Harvesting as per the Authority Specifications.

•

Low-cost Maintenance

•

Lower Water Bills

•

Great for Irrigation

•

Reduces Ground Water Demand

•

Reduces Soil Erosion and Floods

•

Multi-Purpose

Disadvantages • •

Unreliable rainfall Starting costs

•

High-energy Maintenance

•

Storage limits

Surface runoff water harvesting

•

Seepage into the ground have been installed in pedestrian areas , roads and parking.

•

Artificial method of recharging ground water aquifer.

•

Solves water crisis in dry season

•

Drainage problem

•

Submergence problem in city area

•

Reduction in flood level in rivers

Ahmedabad- Rainfall Pattern

•

Average annual rainfall is about 800 millimetres (31 in)

•

According to the annual rainfall- liters of water that can be collected from roof

top rainwater harvesting and runoff surface water: 40,000 litres

Design-Orientation for maximum day light.

• Rooftop Farming • Food harvest • Green Roof • Natural cooling • Protects heat penetration, cuts down heat-island effect • Midrise : Densify Living units • Easy Access to roof/ground level • Ledge Gardening • Spice Garden/Flower Garden • Filters air • Cools the air

Benefits of Rooftop Farming

Social Increase access to healthy food Engage urban schools and families Inspire citizens to grown their own food Create a productive green space Economical Reduce building energy costs Increase life span of the roof Support the local economy Improve property value

Vertical mixed use

Vertical mixed use •

Courtyard Concept- Natural Ventilation

•

Roof garden  Protects heat penetration, cuts down heat-island effect  Absorbing heat and radiating it into the building. This is minimized through the roof gardens covering 55% of the roof area.

•

The solar panels  eastern side and they are sloping  production of energy throughout the day  a commercial building more amount of energy is consumed during the working hours [day] compared to the evenings

Wind Tower

• The hot ambient air enters the tower through the openings in the tower and is cooled, when it • Comes in contact with the cool tower and thus becomes heavier and sinks down.

• When an inlet is provided to the rooms with an outlet on the other side, there is a draft of cool air.

• Warm surface of wind tower and drop in temperature of ambient air due to buoyancy effect.

• Warm air rises upwards.

• Cooler ambient air is sucked into the room through the window.

• As a by-product of this process, wind tower loses the heat that was collected during the day time and it becomes ready for use in cold condition up to the morning.
