**9. Case study in Malaysia**

The Malaysia Industrial Energy Efficiency Improvement Project (MIEEIP) was developed to remove barriers to efficient industrial energy use. The project is also designed to facilitate the reduction in greenhouse gas emission by the industrial sector [41]. The following programmers were implemented:

a. Energy used bench marking

The overall objective of this component is to establish and develop energy use benchmark for the eight industrial sectors that can be used by the industries as a guide in their energy efficient and energy conservation efforts.

b. Energy Audit

The overall objective of this component is to improve the energy efficiency levels in industries by promoting the practices of energy auditing.

c. Energy Rating

The overall objective of this component is to introduce activities that will inform industries about energy efficient equipment energy rating programmers including cost technical specification, economic and energy performance.

d. Energy Efficiency Promotion

The main objective of this component is to disseminate information on energy efficient practices and technology application to the industries

e. Energy Services Companies (ESCO) Support

The overall objectives of this component are to provide engineering services or consultancies, providing financial solution as well as risk mitigation for energy efficiency activities to industries/client.

#### *Case study 1: Tritex Containers Sdn Bhd (Malaysia)*

For more than 20 years the management thought that it was okay to have big boiler for its production process. Little did they realize that oversized boiler was causing inefficient use of energy which eventually meant the company was losing money? Initial finding by the audit team showed that the company had the potential for energy saving as high as USD50,000 a year. The MIEEIP team discovered that most of the energy losses occurred because of uninsulated pipes in the boiler and leakage in the compressed air system and main distribution loops [41].

the designers is to design the software using accurate measurement tools and a proper automated reporting system within an acceptable price. This should include the report of data either hourly or monthly basis so that the verification of the software could be check and in line with historical data. The other important feature that had to be considered in future is the data sharing within the software. Based on the experience it is worth to use the appropriate energy efficient tools as part of energy management for our future sustainability plan. Not only it preserves our environment by reducing the GHG emission but also save

Little did they realize that oversized boiler was causing inefficient use of energy which eventually meant the company was losing money? Initial finding by the audit team showed that the company had the potential for energy saving as high as The measures that were recommended involving no-cost and low cost investment included:


With an initial investment of only USD15,000 the company put in place a more efficient system that resulted in an annual energy saving of USD30,000. Table 3 shows the estimated annual savings from the measures implemented practices.

#### *Case Study 2: Pan Century Edible Oil (PCEO) Sdn Bhd (Malaysia)*

It's total manufacturing capacity of oil refinery product and special product is about one million tones. The factory recorded an annual turnover of USD250 million in 2002. More than 550 tones of steam are generated daily for physical refining, making soap noodles, tank farm heating and fractionation.

During the audit, the team identified significant steam leakages and analyzed the respective losses. With an investment on USD343,000 on the steam optimization programmed, resulted in an annual energy saving of USD229,300. Modification to the factory's cooling towers, replacement of standard high efficient motor, steam conversation scheme, heat recovery scheme and monitoring, which produce another total energy saving

of USD100,000. Table 4 shows the estimate annual saving from the implemented measure practices.

Energy efficiency has become one of the main tasks in energy management. Technical systems and solutions that can save energy and keep the costs down gain an importance decision. At present in buildings, equipment like air-condition, pumps and lighting had consumed high amounts of energy. A small adjustment through energy practices and energy audit can lead to a significant reduced of energy used. It is found that the available commercial tool for analyzing energy consumption and implements energy conserving measures could be a solution to minimize energy utilization. Practices of energy audit and energy efficiency activities in industries had shown a potential saving. An improvement of energy efficiency in building will be among the top priorities in the energy management

#### **Table 3.** Estimate annual energy saving

#### *Case Study 3: JG Container Sdn Bhd*

This company had commenced operation in Malaysia since1970 and total energy costs representing 20% of it turnover. By applying energy efficiency practices 57,300 GJ annual energy saves from the new furnace and 2,800 GJ/annum from improvements in two annealing lehr, saving in fuel cost of more than 33% from heat recovery system for the glass furnace. It is found that by total investment of USD2.5 million made a saving of USD0.6 million per year. Table 6 shows the energy efficient measure and the saving affected.

#### *Case Study 4: HeveaBoard Bhd (Malaysia)*

Saves USD180,000 on annual energy costs, saves 37,000 GJ in fossil fuels and decreases CO2 emissions by nearly 3,000 tonnes each year. Following an energy audit, HeveaBoard, a particleboard manufacturer, replaced its fuel oil fired thermal heater with a wood dust fired thermal oil heater. This allowed the company to capitalize on a cheap source of energy, namely the excessive wood waste left over from production. HeveaBoard also engaged the services of an Energy Service Company (ESCO) to install the system which guarantees results and payment based on energy savings achieved.

#### *Case Study 5: Globalmas Sdn. Bhd. (Malaysia)*

A manufacturer of canned food based in Sarawak recorded an annual turnover of USD1.4 million in 2002 and found ways to slash its operating costs. The company identified the best use of energy consumption during various plant processes by reanalyzing electric, gas, and fuel or steam resources. Globalmas discovered that with a total capital expenditure of USD42,000, the factory could reduce its energy costs by nearly half and recover the investment within a period of 18 months.
