### Energy conservation ppt 23.9.11

1. 1. ENERGY EFFICIENCY FOR HOTELS By Raghunath Patil CE ROC
2. 2. Energy conservation activities be carried out by employees Save Electricity bill by using Electrical equipments within Low rate time zone. At present Rates are as shown in table ( 2011) Turning off lights and air-conditioning in the rooms not in use Energy conservation during room cleaning Switch OFF unwanted lights during day time Instructions and procedures to save energy RD PATIL CE ROC 18.00-22.00 ZONE D Rs 7.45 + 1.10 per unit + TAXES 09.00-12.00 ZONE C Rs 7.45 + 0.85 per unit + TAXES 06.00-09.00 12.00-18.00 ZONE B Rs 7.45 per unit + TAXES 22.00-06.00 ZONE A Rs 7.45 - 0.85 per unit + TAXES
3. 3. How to figure Kilowatt Hours ( UNITS ) For Single Phase : Watts = Volts x Amps. X cos Φ KW = Volts x Amps x1000 For Three Phase : Watts = 1.73 x Volts x Amps. X cost Φ KW = 1.73 Volts x Amps /1000 x X cos Φ Simple thumb rule: 1) 100 wh = 100 Paisa / hr for commercial rate 2) 1 KWH = 1 unit = 1000 wh = 1000 paisa/ Hr = Rs 10 per Hr RD PATIL CE ROC
4. 4. Refrigrator – 165 Ltr = 800 Watts Well Pump ½ HP= 400 Watts Well Pump 1HP= 800 Watts Microwave Oven 1200 Watts Coffee Maker= 900 Watts Dishwasher= 1400 Watts Toaster= 900 Watts Computer= 250 Watts Electric Range-1Burner= 1400 Watts Electric Range Oven= 7500 Watts RD PATIL CE ROC
5. 5. TV - 13&quot; Color= 70 Watts TV - 32&quot; Color= 170 Watts Stereo System= 140 Watts Clothes Iron= 1100 Watts Electric Clothes Dryer= 6000 Watts Washing Machine= 1000 Watts Hair Dryer= 1600 Watts Air Conditioning 1 Ton= 2000 Watts Air Conditioning 2 Ton= 3000 Watts Air Conditioning 3 Ton= 4500 Watts Window A/C= 2000 Watts Ceiling Fan= 100 Watts Vacuum Cleaner= 780 Watts RD PATIL CE ROC
6. 6. FOOD & BEVERAGE DEPARTMENT This department consumes approximately 25% of the total energy cost FOOD PREPARATION - KITCHEN <ul><li>Preheating time for ovens, grills, boilers, fryers & other cooking equipments. 10 to 20 minutes should be sufficient. </li></ul><ul><li>When preheating ovens, set thermostat at the desired temperature. </li></ul><ul><li>U se smaller or more energy efficient oven when possible. </li></ul><ul><li>Use additional fry units, boilers, oven etc. only for peak business hours. </li></ul><ul><li>Load & unload ovens quickly. If an oven door is kept open for a second, it losses about 1% of its heat. </li></ul><ul><li>Oven should not be opened during operation </li></ul>RD PATIL CE ROC
7. 7. <ul><li>Cover pots while cooking. </li></ul><ul><li>Turn off cooking & heating units that are not needed </li></ul><ul><li>Frozen food should be thawed in refrigerators. It will thaw easily & reduce power demand on the refrigerator. </li></ul><ul><li>When using gas range for full heat condition, the tip of the flame should just touch the bottom of the pan or kettle. Yellow flame is the indication of inefficient, incomplete combustion and wastage of gas. Clean burners, pilot light regularly. If flames are still yellow, have gas-air mixture adjusted. </li></ul>RD PATIL CE ROC
8. 8. RD PATIL CE ROC <ul><li>A blue flame with a distinct inner cone is best. Adjust flame until it is entirely blue. </li></ul><ul><li>Thoroughly clean pot & pans to ensure there is no carbon build up at the bottom. </li></ul><ul><li>Fryers need to be cleaned & oil filtered at least </li></ul><ul><li>once a day. </li></ul><ul><li>Cooking rang burners should always be smaller than the kettle or pot place on it. </li></ul><ul><li>Turn off Rotary Toaster when not in use. Use pop up toasters on lean timings. </li></ul><ul><li>Shut off steam Heater on dishwasher when dishwasher in not in use </li></ul>
9. 9. <ul><li>In pot washing area fill sink for washing utensils instead of running water. </li></ul><ul><li>Do not use dishwasher till full load of soiled dishes is available. </li></ul><ul><li>Turn off lights in the walk – in refrigerators and freezers when not required. Lights not only waste energy but add load to the box. </li></ul><ul><li>Close tightly all walk-in doors after operating them. </li></ul><ul><li>Avoid frequent opening of door </li></ul>RD PATIL CE ROC
10. 10. <ul><li>Allow hot foods to air cool before placing in refrigerators </li></ul><ul><li>Do not store items in front of the refrigerant coils or fans in a manner that restricts air circulation. </li></ul><ul><li>Fully stored refrigerators and walk-ins use energy more efficiently than partially stored ones. </li></ul><ul><li>Turn off supply and exhaust fans in kitchens stores etc. when areas are not in use. </li></ul><ul><li>Report and leakage of gas immediately. </li></ul>RD PATIL CE ROC
11. 11. RD PATIL CE ROC <ul><li>Keep records of all break down of equipments to find out accident prone/uneconomical equipment. </li></ul><ul><li>Turn on equipment only as needed. Make sure they are turn off at night. </li></ul><ul><li>Keep equipment and door seals clean and free of debris to prevent energy waste </li></ul><ul><li>Try to avoid use of electrical appliances at high rate time zone (18.00- 22.00) . It will help you to reduce electricity bill </li></ul><ul><li>Avoid to turn on gas burners until you are ready to cook. </li></ul>K eeping the flame of the larger burner burning unnecessarily in a gas stove, results Even a few paise saved everyday
12. 12. <ul><li>Use flat bottom pots and pans for maximum heat transfer. </li></ul><ul><li>Do not leave water taps running. </li></ul><ul><li>Keep an eye on the preventive maintenance schedule of all quipments to ensure timely compliance. </li></ul><ul><li>Close & preferably lock ice cuber bins after removing ice for use. </li></ul>RD PATIL CE ROC
13. 13. BANQUETS / BOARD ROOM <ul><li>While air conditioning is on, try to avoid using candles on the table. They add a tremendous heat load. </li></ul><ul><li>When setting up for a function, make certain that AC and lighting are off until ½ hour before function starts. Turn off systems as soon as the function is over. In fact, air conditioning can be turned off even ½ hours before function finishes. </li></ul><ul><li>If you have a choice, try to avoid function that requires the addition of many spotlight or other heat producing equipment. </li></ul>RD PATIL CE ROC
14. 14. RD PATIL CE ROC <ul><li>Assign an individual responsible for turning lights on and off. </li></ul><ul><li>Keep the light off whenever any function area is vacant or unoccupied. </li></ul><ul><li>ensure that all doors and windows are properly closed. </li></ul><ul><li>During winter season try to use outside air for cooling. </li></ul>RD PATIL CE ROC
15. 15. <ul><li>Do not rent a 300 person hall room to 50 people . </li></ul><ul><li>Lighting control in banquet halls </li></ul>RD PATIL CE ROC

17. 17. FRONT OFFICE AND LOBBY MANAGERS <ul><li>When occupancy is unfortunately not high, front office should block complete floors This would certainly help reduce air conditioning load and result in saving of energy </li></ul><ul><li>Front office should make sure that the rooms which are not to be rented out during lean period are not air conditioned or ventilated unnecessarily. If any one of these is to be rented. out, air conditioning or ventilation can be started ½ hour before the guest moves in. </li></ul><ul><li>Switch OFF all lighting during late night and day light hours. Turn off all lights , computer in offices when these are closed. </li></ul><ul><li>Lobby, managers should ensure that Lobby Main Entrance doors are not unduly kept opened. A door opening will result in ingress of heat from outside and adversely effect air conditioning. </li></ul>RD PATIL CE ROC
18. 18. <ul><li>During day light hours reduce electric lighting load in Lobby etc. to minimum to make full use of natural light. </li></ul><ul><li>Front office can play an important role in energy conservation. When occupancy is unfortunately not high, front office should rent room by virtue of their location. Top floor rooms must be warmer. Rooms close to heat source should be avoided if possible. This would certainly help reduce air conditioning load and result in saving of energy. </li></ul><ul><li>As soon as guest checks out, Front office should inform Housekeeping so that all lights of the vacant room is switched off at the earliest. </li></ul>RD PATIL CE ROC
19. 19. <ul><li>Report broken windowpanes to stop ingress of air. </li></ul><ul><li>Inspect public toilets periodically and report leading W.C. and faucets top stop water unnecessary illumination. </li></ul>RD PATIL CE ROC
20. 20. HOUSE KEEPING DEAPRTMENT The major space in a hotel is devoted to guest rooms and corridors. Although the energy conserved in one room or corridor does not seem significant, but when multiplied by 115 or so rooms, it does become significant. Some of the opportunities for Housekeeping Department where they can significantly contribute to energy saving listed below:- <ul><li>Turn off guest room lights when rooms are not physically occupied. </li></ul><ul><li>Use minimum lighting when making up and cleaning rooms. Use natural light whenever possible. </li></ul><ul><li>Turn off corridor lights, or reduce it to 50% when natural light is available. </li></ul><ul><li>Turn off lights in linen rooms, storage room and maids closets when not in use. </li></ul>RD PATIL CE ROC
21. 21. <ul><li>Check your areas for light level. Reduce number of lights if possible. Use lower wattage bulbs wherever possible. </li></ul><ul><li>Have lamp shades cleaned at once. Bulb gives more light with clean lampshades. </li></ul><ul><li>Keep walls and ceiling walls cleaned for better light reflection. </li></ul><ul><li>Report water leaks immediately </li></ul><ul><li>Keep windows closed and curtain on. The ingress of hot air in summer and cold air during winter contribute to very large waste or energy. For example 6’ wide window opened just one inch would allow hot air necessitating 1.76 kwh to cool. This in terms of monetary value, will cost approx. Rs. 17.60 </li></ul>RD PATIL CE ROC
22. 22. <ul><li>Keep room hot water temperature at lowest acceptable limit. </li></ul><ul><li>Leave only such lights on which are actually needed by the guest while leaving the room. </li></ul>RD PATIL CE ROC
23. 23. LAUNDARY <ul><li>Operate washing machines at full load, partial loads may require same amount water as full loads. </li></ul><ul><li>Do not leave water taps running. </li></ul><ul><li>All steam line values should be checked for leaks. That is, you should be able to shut off steam to any machine not in use keeping steam supply main open. </li></ul><ul><li>If possible use final rinse water for 1st wash. </li></ul><ul><li>Periodically clean exhaust duct and blower of lint and dust. </li></ul>RD PATIL CE ROC
24. 24. <ul><li>Keep steam pressure at lowest possible level. </li></ul><ul><li>Shut off steam valve whenever machine is not being utilised </li></ul><ul><li>Keep radiator coils and fins free from dirt all the times. </li></ul><ul><li>Ensure that Drying tumblers and washing machines are kept clean and free from scale at all times. </li></ul><ul><li>Switch off laundry exhaust fans when laundry is closed. </li></ul><ul><li>Reschedule machine operation to reduce peak demand charges. </li></ul><ul><li>Inform boiler room when steam is not required so that boilers can be shut down to save fuel. </li></ul>RD PATIL CE ROC
