IDEA :

To construct an eco-friendly, energy conserving and self-sustaining hostel

with innovative infrastructural facilities in a flood prone region.

Basic Design :

No. of floors : G + 3

No. of rooms : 500

The shape of many objects moving through air or water is designed in such a

way(with pointed ends) that friction can be reduced between the objects and water

or air(fluid).The shape of the body is called streamlined body.

We know that the flood water would not be static and depending on the rise andfall of the river levels it is highly plausible that the flood water would keepflowing. Hence, since the drag force is immensely less for a curved hexagonalstructure than that for rectangular one, it has been chosen.

This phenomenon can be explained by boundary layer approximations and wehave shown it with the help of fluent model which clearly shows that the dragforce acting is very much high compared for rectangular model as compared tocurve hexagonal model.

Cylindrical Structural Feature in centre :

Storage house

Safer space to house evacuated ground floor residents. Mess and water accessibility. Also Electricity Supply.

Inter-connected to the other parts by corridors to ease the in and

outflow. Has an additional outer protective layer to protect it from an inward

collapse of the main building.

Despite a circular structure having the least drag, it has not been used,taking into consideration the huge construction cost and spacerequirements. Optimizing these factors, the curved Hexagonal shape

was found to be the most optimum as it fits best for both economic

considerations as well as design consideration.


12/25

Other Salient Features :

Height of the ground floor is kept high keeping into account the maximum

probable height that can be reached by floodwaters. The model is based on astatistical evaluation system , which can be continuously updated giving afuturistic.

The ground floor of the hostel would be made of Portland Pozzolana Cementwith the use of adhesives, the same kind used in construction of dams. There

would also be an additional coating of Polyester Epoxy Paint.

Discretizing the electrical supply to each floor, with a cut-off alternative oneach floor in case of an overloading hazard during floods so as to keep otherfloors unaffected.

To lower the intensity of water inside the hostel, we will take advantage of subsurface flow, and not the conventional drainage system which usually leads toopposite flow in case of floods and exacerbate the problems of floods evenfurther.

Apart from this, It will be ensured that water would be stored In anoverhead Sintex tank, so that even in the occasion of power cuts,availability of safe water can be ensured.

As we know that during the case of a flood, the drainage systemcollapses and this is the prime reason for the contamination of water,the water in the overhead tank would be accessed by only one pipeconnected to an emergency tap and would not be used on any otherday.

Sintex tanks are known to preserve potable water for up to 10 days, inthis case, we may have the tank filled with fresh water, every 5 days inorder to ensure that we have safe water for at least 5 days in case of aflash flood.

In order to tap the energy of the subsurface discharge in case offloods, the turbines ( smaller versions ) can be used to tap thedirected flow.


14/25

Eco Sustainability :

Smart Hostel would be supported by ceramic roofing on the top. This is owing to thefact that the insulating and corrosion-resistance properties of these products areexcellent. The ceramic compound with a high quality acrylic binder providesadequate elasticity and a strong adhesion. The reflective ability of the ceramiccompound will reflect as much as 96 per cent of heat waves reaching the surface(where applied), thus lowering the conductive transfer of radiant heat to the inside.

Solar Geyser: Beneficiary has to pay Rs. 12,000 for a solar heating unit costingaround Rs. 20,000

The use of CFLs ( Compact Fluorescent Lamps ) can greatly reduce the powerexpenditure of a hostel. The CFL Lamps ensure adequate lighting as well as arepretty much cost effective.

FLOATING TYPE BIOGAS PLANT:

Smart Electricity for rooms


15/25

BIOGAS PLANT :

In order to cater to energy needs of a large hostel taking into account the

minimization of the waste this is the most efficient and clean-green method.

Floating biogas type plant has a better efficiency than the fixed drum digesters.


16/25

COMPOSTING TOILETS AND ECO-SANS:

A few working examples : KfW Frankfurt , Germany and Guangxi Province inChina.

Often, water used in flush toilets is of drinking quality. Only 1% of global water isdrinkable, therefore, it is a precious resource . Water fit to drink is being used forother purposes that can use lesser quality water, such as toilets. But if we used thewater in toilets to help with the bad water, many lives would be saved.


17/25

UTEC POTABLE WATER GENERATOR :

To Generate Potable water; extremely beneficial in case of a drinking water crisis.

Pure water ( in case of effluent rise in the underground water systems ).

SMART FEATURES :

Apart from the core structural features we plan to incorporate a number ofintriguing smart features :

SMART LOCKS in rooms to judicially use electricity. Motion Sensor Washrooms and bathrooms, ( Both in electricity as well as water

management . ). Ambient Light Sensors to incorporate power sustainability . Guiding Monitors to append hostel maps. CCTV cameras to monitor the in and outflow of people. Central Alarming system to acquaint people of the impending hazard.


20/25

Virtual mobile canteen service :

Usual problem to wait around in the canteen before the dish is prepared.

The proposed virtual canteen service aims to provide an entirely new andinnovative platform to solve the above problem.

Using a computerized system ( similar to the Mess on Cloud initiative ), the

student can place the order sitting in his room thus saving his much precious

time. As a result the proposed system can effectively improve the serviceabilityof the students canteen.

COST ESTIMATION:

For the ground floor, walls would have an extra layer of Polyester Epoxy paintassumed to be 2 mm thick. To cover the entire ground floor, the total quantity

required would be ( 62.5 * 3* 4 *1000* 0.002 + 75*3*2*1000*0.002) = 2500 litres. Which would come about to 3600 litres taking into consideration Windows etc. Cost= 2500*110 = INR 3 lac. Cost of installing solar geyser is minimal as the government subsidies will take

care of the incurred cost.

50% government subsidy also available for biogas plants, hence approximatelycost would come out to be INR 1,00,000.

Motion sensor bulbs10 watt (in worst case)= 300 required.installation cost = 300*500 = INR 1.5 lac.Electricity consumed = 300*5*10*30/1000 = 450 units *4 = INR 1800/month

worst case Total cost in 5 years= 150 000 + 1800*60= INR 159 000 Conventional 15 watts CFL ( Compact Fluorescent Lamps).

Installation cost = 300*120 = 36 000Electricity consumed = 300*12*15*30/1000=1620 units*4 = INR 6480/month

Life of CFL = 1 year

Total cost of CFL in 5years=36000*5+6480*60= INR 568800

Cost analysis of the BIOGAS PLANT :

Steel and plastic are used in some floating-dome plants. These can be pre-fabricated and thus installed very quickly. BIOTECH sells prefabricated plants for

suburban homes with the gas container made of fibreglass-reinforced-plastic andthe slurry container from Ferro cement, and a 1m3 plant costs about US$220 ( per4 residents ). equivalently INR 11954 .

Thus effective cost would be 220/4 * 500 * 54 ~ INR 15 00 000.

The average annual energy savings for a 3m3

plant are about INR 2300 ( net ) .`

RECYCLERS :

The average setting up cost for the recyclers would be around, INR 10,000.


23/25

Overall Feasibility:

As elaborated the proposed model is excellently prepared to tackle floods and ishighly feasible. Necessary medical equipment, storage facilities, independent

electrical connections, along with backups during crisis make it even more viablealternative.


24/25

OUTREACH :

Circular structural instead of the hexagonal.

Using the Bio-Sensors to further improvise on the security issues. Use of Composting Toilets instead of the regular toilet systems. Solar panels. Piezoelectric power.
