TECHNICAL WORKING GROUP III : Energy Efficiency Master Plan
Hotel Grand Candi, 10-11 July 2011
Background
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.
Background
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.
Background
Presidential Instruction No. 9 of 1982 .The steps of energy conservation through:
a) The energy-saving campaignb) Training of conservationc) Demonstration and examples of energy-efficient appliancesd) conservation technology R & De) Development of energy audit, identify potential efficiency improvements f) Standardization

For the one month:With the light bulb uses = 27 kWhWith 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 = 704.892.794,40Total saving cost = Rp.
19.264.916.568,60
Save: 20,7 kWh
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)
For three classes (450, 900, 1300 VA)
We can see that the payback will be got after almost only two-half months.

Business Sector
Increasing the awareness of costumer’s electrical usage
Replacing the conventional tools with the energy saving one
TIME MANAGINGAccording 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.

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.

Industrial Sector
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.
