TECHNICAL WORKING GROUP III Energy Efficiency Master Plan

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 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

PLAN TARGET OF ENERGY EFFICIENCY 1 The details and profile of energy use in the household sector, industrial, and commercial buildings in Central Java. 2 Identification of energy waste and potential savings in the household sector, industrial and commercial buildings. 3 4 5 Recommendations of energy saving measures. The priority or order of application of energy conservation based on the technical, financial and environmental. The feasibility study recommended Energy Conservation Projects which require a fee (medium / high cost).

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

TIME MANAGING 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.

Replacing solar-fuel boiler with heat exchanger 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.
