1. TECHNICAL WORKING GROUP III : Energy Efficiency Master Plan Hotel Grand Candi, 10-11 July 2011

2. Energy has a very important role and become a basic necessity in national sustainable development. Therefore, energy should be used sparingly, rational, and wisely so that the energy needs in the present and the future can be met.

3. If the policy to conserve energy, encourage use of renewable energy and carbon emission reduction is adopted, the energy requirement would be reduced by 12-16 percent.

4. Presidential Instruction No. 9 of 1982. The steps of energy conservation through: a) The energy-saving campaign b) Training of conservation c) Demonstration and examples of energy-efficient appliances d) conservation technology R & D e) Development of energy audit, identify potential efficiency improvements f) Standardization

14. No Cost. By turning off 2 bulbs in specific time (ex: 5pm – 10pm). Bulb has 60 Watts, every house can saves 600 watts.

15. in one month, every house can save : = Rp. 15.435,- Everymonth saving Rp. 15.435,- x 6002195 = Rp. 92.643.879.830 It saves up to 108 GW LEVEL Price (Rp./kWh) HouseHold Type - 1 (450VA) 495,00 Type - 1 (900VA) 495,00 Type - 1 (1300VA) 790,00 Type - 1 (2200VA) 795,00 Type – 2 890,00 Type – 3 1.300,00 AVERAGE 857,50

19. For three classes (450, 900, 1300 VA) For the one month: With the light bulb uses = 27 kWh With energy saver bulbs = 6,3 kWh 450 VA = 20,7 x 790 x 495 x 3.980.991 = 13.020.229.164,60 900 VA = 5.539.794.609,60 1300VA = 704.892.794,40 Total saving cost = Rp. 19.264.916.568,60 Save: 20,7 kWh

20. For the second month and so on we just need to accumulate of the total saving cost per month. With investment for three category is Rp. 35.000,- x total household customer x 20% = 41.232.317.000,00 / month So NPV can be found as shown in the graphic: For three category (450, 900, 1300 VA)

21. For three classes (450, 900, 1300 VA) We can see that the payback will be got after almost only two-half months.

22. Replacement the refrigerator For general, the old refrigerator: 0,15 kW the new ones: 0,07 kW (single door) Using time is 24 hours and discount rate 12% / year. BEFORE : acc. Energy/month = 0,15 x 24 x 30 days = 108 acc. Energy cost = 108 x Rp 495,- = Rp. 53.460,- With IRR= 0,99 <<, DR = 0,01 Monthly cost = (IRR x DR x acc. Energy cost) = Rp. 52.930,69 AFTER : Rp. 22.936,63

23. Replacement the refrigerator

24. Energy cost saving = Rp. 29.994,06 PER MONTH With the investment to buy new refrigerator is Rp. 1.000.000,- The payback is after 60 month or five year.

26.  Increasing the awareness of costumer’s electrical usage  Replacing the conventional tools with the energy saving one

27. According to survey in a hotel in Central Java, because of time managing, this hotel can save the price up to Rp 62,927.44 a day. It mean, in 1 month, that hotel can save up to Rp.188,782.32. If all hotel in Central Java (106 star hotels) organize a usage of its electrical tools, hotel business in Central Java can save money up to Rp 20 million/month. Just imagine, there’s 1090 not starred hotels in Central Java.

28. With the same calculation with the household, for replacing 20 lamps, we get chart as below:

29. Comparison solar-fuel boiler with heat exchanger BoilerHeat Exchanger Price (Rp.)35,000,00042,000,000 Diesel Oil costRp 4,500- Diesel Oil cost (for 2500 VA)Rp 1,800/kWh- watt hours per days10,000- watt hours per month300,000- kWh per month300.00- Monthly payment540,000.00-

30. From the data above, it can be concluded that the boiler using additional cost per month as a fuel, while the heat exchanger is not. From the data above obtained calculation results that by replacing the heat exchanger obtained BEP (Break Event Point) in the next 11 months from the time of initial purchase.

31. The main factors of energy optimization are as follows:  Settings "on time", just as long as needed only.  Modifications at the time, detector occupancy, building automation systems, and so on.  Optimal speed settings.

33. 11 kW 15 kW 18,5 kW DESIGN = 12,5 kW ACTUAL = 12,5 kW x SAFETY FACTOR = 12,5 kW x 1,3 = 16,25 kW OPTIONAL = 18,5 kW

34. SAVING : - REPLACEMENT MOTOR = 18,5 kW - 15 kW = 3,5 kW - INSTALLATION VARIABLE SPEED DRIVE = 18,5 kW - 12,5 kW = 6 kW VARIABLE SPEED DRIVE WILL USE ENERGY ACCORDING TO THE LOAD CAPACITY NEEDS.

37. The savings on motor done with the installation of temperature sensors and the installation of variable speed drives. Variable speed drives will use energy according to the capacity needs of the load by regulating the speed of the fan motor.
