TWO TYPES OF SOLAR WATER HEATERS
ARE AVAILABLE IN THE MARKET. ONE WITH FLAT

EVACUATEDTUBECOLLECTORS(ETC).
FPC BASED SYSTEMS ARE OF METALLIC TYPE AND
HAVE LONGER LIFE AS COMPARED TO ETC BASED
SYSTEM WHERE TUBES ARE MADE OF GLASS
WHICH ARE OF FRAGILE IN NATURE. ETC BASED
SYSTEMS ARE, THEREFORE, CHEAPER THAN FPC
BASED SYSTEM.
HENCE, WE WOULD SUGGESTFPC BASED SYSTEMS BE INSTALLED FOR
LONGER LIFE.
200L FPC BASED SYSTEMS REQUIRE MAXIMUM SOLAR COLLECTOR AREA OF 4
SQ.M. AND COST ABOUT 42000/- PER SYSTEM.
THEREFORE, 23 SYSTEMS WILL COST ABOUT 9,66,000/-

CARD KEY SWITCH IS THE ONE-OF-A-KIND SWITCH ACTIVATED BY KEY CARDS AND TURNS ELECTRICAL CIRCUITS ON OR OFF WHEN A KEY CARD IS INSERTED OR REMOVED FROM ITS SLOT.
ENERGY-EFFICIENT CARD KEY SWITCH, HELPING THE CAMPUS REDUCE ENERGY CONSUMPTIONIN EMPTY HOSTEL ROOMS OR EVEN HOUSES.
• REDUCES THE AMOUNT OF ENERGY EXHAUSTED ON LIGHTING, HEATING AND COOLING UNOCCUPIED ROOMS
• UP TO 30% REDUCTION IN ENERGY CONSUMPTION
• INITIAL INSTALLATION COSTS CAN BE RECOUPED IN LESS THAN FOUR YEARS
• RUNNING WIRES TO THE CONTROLS NOT REQUIRED FOR INSTALLATION OF THE SYSTEM
• THE SWITCH IS EASILY PROGRAMMED TO THE CONTROLLER
• KEY SYSTEM LIKE THOSE IN HOTELS..WHERE TAKING OUT KEY TURNS OFF EVERYTHING INSIDE THE ROOM..PROBABLY LEAVE ONE PLUG POINT
TO CHARGE THINGS
• A NORMAL KEY WOULD BE ATTACHED DIRECTLY TO THE CARD. THE KEY WOULD OPEN AN ORDINARY LOCK ON THE DOOR AND THE CARD WILL SERVE ONLY AS A CIRCUIT BREAKER.

DELHI
THE NATIONAL CAPITAL TERRITORY, (NCT), OF DELHI RECEIVES 611 MM OF RAINFALL ON AN AVERAGE ANNUALLY AND THE NUMBER OF RAINY DAYS ARE
AS LOW AS 20-30. (A RAINY DAY IS SPECIFIED AS A DAY WITH MORE THAN OR EQUAL TO 2.5 MM OF RAINFALL). THE GEOLOGY OF DELHI COMPRISES
ALWAR QUARTZITES AND ALLUVIUM WHOSE VERTICAL HYDRAULIC CONDUCTIVITY, (PERMEABILITY), IS HIGH COMPARED TO THE HORIZONTAL
PERMEABILITY. THIS MAKES THE CONDITIONS FAVOURABLE FOR ARTIFICIAL RECHARGE.THUS MOST OF THE URBAN RAINWATER HARVESTING EFFORTS
REVOLVE AROUND RECHARGE OF AQUIFERS WHICH IS THE BEST OPTION AVAILABLE TAKING INTO CONSIDERATION THE RAINFALL PATTERN AND
AVAILABILITY.
ARCHITECTURAL INTERVENTION
FOR CRYSTALLINE AND AMORPHOUS SILICON MODULES
THE AVERAGE IRRADIATION IS IN KWH/M2
, AND THE ELECTRICAL OUTPUT IS IN MEGA WATT HOUR.
ROOF AREA OF THE HOSTEL- 2100 SQM
APPROX AMOUNT OF RAINFALL- 1281000 LITRES
QUANTITY OF WATER AVAILABLE FOR HARVESTING- 769860 LITRES
THESE PANELS WILL HELP IN
HARVESTING RAINWATER AND
GENERATING SOLAR POWER. THEY ALSO
GIVE SHADE TO THE ROOF WHICH GETS
EXCESSIVELY HEATED UP DURING ANY
SUNNY DAY. THEY GIVE A SENSE OF
ENCLOSURE TO THE SPACE ON THE
ROOF WHICH MIGHT BE OF SOME USE
AFTER THESE PANELS ARE SET UP. THESE
ATTRIBUTES MAKE THIS APPARATUS A
HUGE ENERGY CONSERVATOR.
UNDER CLEAR SKIES AND GOOD SUNSHINE EACH SQUARE METER IS RECEIVING ABOUT 1000 WATTS OF SOLAR ENERGY. AT TYPICAL 15% PANEL
EFFICIENCY, A 10 SQ M AREA WILL GENERATE 1 KILOWATT OF POWER. AFTER LEAVING SOME FREE SPACE, ABOUT 10-12 SQ M CLEAR ROOF AREA
WILL BE REQUIRED.
ROOF AREA- 2100 SQ M
NO OF KILO WATTS WE CAN PRODUCE ( ASSUMING HALF OF THE ROOF WILL BE PRODUCTIVE)- 105 KW/HOUR
THAT AMOUNTS TO AROUND RS.700 PER HOUR.

7. BEHAVIOURAL CHANGE IN HOSTEL
STUDENT’S CULTURAL ACTIVITIES CAN APROACHTHE SUBJECT OF CONSERVATION
. AWARENESS MONTH FOCUSSING ON EDUCATING STUDENTS AND STAFF
MOVIES, POSTERS, ARTWORK AND PLAYS CAN BE SPONSORED BY THE COLLEGE TO ENCOURAGE STUDENTS
. FOR EXAMPLE CONDUCTING AN ENERGY AUDIT HAS MADE STUDENTS CONSCIOUS OF THEIR CONSUMPTION
THE AFTER EFFECTS OF SUCH AN AWARENESS CAMPAIGN WILL SLOWLY START CREATING A DIFFERENCE IN THE DAILY HABITS OF PEOPLE
THE FOLLOWING MEASURES CAN BE TAKEN TO BRING ABOUT AN AWARENESS:
• REGULAR MONITORING OF ENERGY CONSUMED BY PARTICULAR SECTIONS OF THE HOSTEL
A COMPARISON OF DIFFERENT SECTIONS ON PUBLIC DISPLAY AND AWARDING THE LEAST CONSUMERS WOULD COMPEL STUDENTS TO USE LESS
IN ORDER TO GAIN PERKS. INSTALLING SUB METERS IN EACH CORRIDOR TO MONITOR ELECTICITY USAGE BY EACH CORRIDOR. THE CORRIDOR
WHICH CONSUMESTHE LEST ENERGY SHALL BE AWARDED.
WINDOWS SHOULD CLEANED MONTHLY
STUDENTS SHOULD BE ENCOURAGED TO CLEAN WINDOWS REGULARLY
HOSTEL CLEANING DRIVES CAN BE ORGANISED MONTHLY OR EVERY TWO
MONTHS
STAFF CAN BE GIVEN INCENTIVES ONCE A MONTH TO PARTICIPATE IN THESE
CLEANINGDRIVES
FIXTURES CAN ALSO BE CLEANED SO

9. THERE ARE A NUMBER OF THINGS THAT ALL HOMEOWNERS CAN
DO TO MAKE SIGNIFICANT REDUCTIONS IN THEIR ENERGY
CONSUMPTION. THE FOLLOWING STEPS CAN BE TAKEN BY THE
OWNERS OF THE HOUSE TO REDUCE THEIR ENERGY USE AND
THAT IN TURN CONTRIBUTE TO THE OVERALL ENERGY EFFICIENCY
OF THE HOUSE :
CHOOSEENERGYSTARAPPLIANCES
LABELED PRODUCTS REDUCE THE
AMOUNT OF ENERGY CONSUMED BY
EITHER AUTOMATICALLY SWITCHING TO A
‘SLEEP’ MODE WHEN NOT IN USE AND/OR
REDUCING THE AMOUNT OF POWER USED
WHEN IN ‘STANDBY’ MODE
USE LESSWATER
REPLACING AN OLD TOILET WITH A 6 LPF
TOILET CAN SAVE AN AVERAGE OF 40 LITRES OF
WATER PER PERSON PER DAY. THE KEY
FEATURE OF THESE TOILETS IS A 3/6-LITRES
TWO-BUTTON FLUSHING SYSTEM---ONE BUTTON
FOR LIQUID WASTE AND THE OTHER FOR SOLID
WASTE.
USE WINDOW TREATMENTS TO CONTROL HEAT LOSS AND HEAT
GAIN.
• REGULAR CLEANING OF WINDOWS TO INCREASE THEIR
EFFICIENCY, ESPECIALLY FOR WINTER SUN.
• LOUVERS OR SHADES ON WINDOWS - BLOCK UNWANTED
HEAT GAIN. (HUNTER DOUGLAS DUETTE SHADES)
• DRAUGHT PROOFING WINDOWS
TO DRAUGHT-PROOF YOUR HOME YOU SHOULD BLOCK UP
UNWANTED GAPS THAT LET COLD AIR IN AND WARM AIR
OUT. SAVING WARM AIR MEANS YOU’LL USE LESS ENERGY
TO HEAT YOUR HOME, SO YOU'LL SAVE MONEY AS WELL AS
MAKING YOUR HOME SNUG AND PLEASANT.
SWITCH APPLIANCES OFF
WHILE WE MAY SWITCH OFF APPLIANCES, THEY
CONTINUE USING ENERGY WHILE THEY ARE ON
STANDBY. YOU CAN SAVE ENERGY BY TURNING
APPLIANCES OFF AT THE POWER POINT WHEN
THEY ARE NOT IN USE.
10. LIGHTS OFF
REMIND YOURSELF AND OTHERS IN YOUR
HOUSEHOLD TO TURN LIGHTS OFF WHEN YOU
EXIT A ROOM, EVERY TIME
USE LESS AIR-CONDITIONING
AIR-CONDITIONING MAKES UP 40% OF ALL
ELECTRICITY USED IN SUMMER. AND THOUGH IT
MAY BE IMPOSSIBLE TO BYPASS USING AIR-
CONDITIONING COMPLETELY, KEEPING THE AIR-
CONDITIONER BETWEEN 23 AND 26 DEGREES WILL
ALLOW YOU TO KEEP COOL WHILE USING LESS
POWER.
DRESS FOR THE CLIMATE
YOU CAN EASILY CUT DOWN ON POWER USED TO HEAT
AND COOL YOUR HOME BY DRESSING MORE
APPROPRIATELY FOR THE CLIMATE.
WASHCLOTHESIN COLD WATER
WASHING CLOTHES IN COLD WATER INSTEAD OF HOT
WATER CAN SAVE A SIGNIFICANT AMOUNT OF ENERGY.
TURN HEATING OFF WHILE YOU SLEEP
WITH BLANKETS AND DOONAS, LEAVING
HEATERS SWITCHED ON WHILE YOU SLEEP IS
UNNECESSARY.
