TWO TYPES OF SOLAR WATER HEATERS
ARE AVAILABLE IN THE MARKET. ONE WITH FLAT
PLATE COLLECTORS (FPC) AND THE OTHER WITH
EVACUATED TUBE COLLECTORS(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 SUGGEST FPC 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 CONSUMPTION IN 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. HENCE ,ONE CAN HAVE THE PRESENT DOOR SYSTEM ALONG WITH THIS NEW KEY CARD SWITCH

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 APROACH THE 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 CONSUMES THE 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 CLEANING DRIVES
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 :
CHOOSE ENERGY STAR
APPLIANCES
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 LESS WATER
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.
WASH CLOTHES IN 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.
