Summary on electrical load studied at LFS :- | Study of Electrical load at LFS | | Sl. No. | Room No. / Area | Light Quantity | Fan Quantity | Regulator to be changed | Sub Total of load for light and Fan in Watt. | Sub Total Load of AC, cooler, Exhust, PC in Watts. | Total load in KW | | 20 W | 36 W | Tolet / Corridor 36W | 36 W on board | 80 W | 50 W | | 1 | Ground floor | 47 | 49 | 70 | 70 | 55 | 83 | 92 | 16,294 | 16,850 | 33 | | 2 | 1st.

(Few Rooms not checked ) | | 400 | 200 | 70 | 200 | 140 | 250 | 50 | 80 | 130 | | | Percentage | | 60% | 30% | 10% | 59% | | 74% | 38% | 62% | | Action on other than lights and fans 
- For operating 21 nos. AC 20% power is being consumed
Need following action:- - Need to keep door and windows close, including door for attached toilet.
- Better to put auto door closer.
- Need study of gap beside door and window and eliminate them.
- Need to switch off 15 min. in advance before leaving / closing room.
- Use AC , when really it required. Try to manage with Ceiling fan.
Our initial Recommendation for Savings of Electricity at LFS , Jamshedpur | Sl. No. | Observation | Recommendation | Benefit | | 1 | Old Resistance type Fan regulators in use in 74% rooms | Need to put electronics type regulators in all rooms | Saving of energy | | 2 | Tube light 36 W / 40 W fitted in 100% classes | Can be replace by T5 ( 28 W ) electrical efficient light | Savings of energy | | 3 | Tube light 36 W / 40 W fitted in 13 nos. Toilets | 15 W CFL is sufficient in existing point | Savings of energy | | 4 | 59% Ceiling fans are of old type ( 80 W) in most of the classes | 50 W Ceiling fan can be fitted | Savings of energy | | 5 | Tube light 36 W fitted in corridor | Can be replaced by 15 W CFL. | Savings of energy | | 6 | In black board 4 nos. tube light 36 W / 40 W fitted in all classes | Can be replaced by CFL 11 Watt. | Savings of energy | | 7 | In 80% class room many room 8 nos. tube light fitted on top of the roof, resulted poor illumination and vibration of fan blades. | The number of light can be reduced to 4 nos. and height can be lowered down | For better illumination | | 8 | Observed Curtain used in many room , which is obstructing entry of natural light | The curtail can be removed mainly from class room , library, | For natural illumination | | 9 | The hazy glasses in the window found in nos. room , obstructing entry of sun light | Can be replaced by transparent glasses for entry of sun light. | Entry of sun light through window | | 10 | Most of fans are fitted at 14 ft. height , resulted lesser effectiveness of spreading of air | The fan position can be lowered down to 10ft ( light at 9ft) by putting extension pipe. | Improvement in efficiency in air flow | Our initial Recommendation for Savings of Electricity at LFS , Jamshedpur | Sl. No. | Observation | Recommendation | Benefit | | 11 | Due to putting of multiple switches , putting of so many lights and fans are trouble some for the students and found not put off in many occasions. | Need main switches in every class | | | 12 | 3 nos. Exhaust fan in class – V C | The exhaust fan can be removed from the room | | | 13 | External lighting system off / on system under manual operation. | Timer can be fitted for auto switch off. | | | 14 | Position of switch board not nearer to entry door in many classes / laboratory resulted fan / lights are not being put off. | Need shifting of switch board beside entry door only at suitable height | | | 15 | In few rooms natural light is unable to entry due to wall | Where ever is possible window can be made for entry of natural light and air | | | 16 | The socket of the 3 pin plugs is found connected with electric board | The plug to be kept in remove condition where ever not in use. | | | 17 | Gaps in the doors and windows in AC room | Sealing of room to be studied and reduced accordingly. | | | 18 | Gap beside exhaust fan | | | | | | | | | | | | | 
Leaning for the project - What is electricity and their difference appliances.
- Which consume more power, What is old , what is new, etc.
- How to calculate power consumption.
- Option available related to electrical appliances.
- How to calculate recovery period.
- What is safe and what is not safe for school children .
- How to do safety audit and record observation.
Further plan / Future Project - Same learning will be shared with other schools of the Jamshedpur city.
- Try to reduce electrical bill of the others 6 schools within 2012.
