About The Handbook China has an ambitious goal of cutting energy consumption per GDP by 20 percent of levels by The scheme is directed at large enterprises in key industries such as power generation and construction materials. Improving energy management of SME scan significantly help China achieve its energy conservation and emissions reduction goals. This energy management handbook was created by BSR, a leader in sustainability management, after a series of studies on manufacturing SMEs. The studies examined the challenges faced by these companies, and explored costeffective energy-saving methods. This booklet teaches SMEs how to establish energy management systems, explains the concepts and procedures of an energy audit, and introduces methods of energy efficiency diagnostics as well as energy efficiency technologies and best practices.
The number of companies employing professionally trained energy managers is large and growing. For some of these people, energy management will be their primary duty, and they will need to acquire in-depth skills in energy analysis as well as knowledge about existing and new energy using equipment and technologies. For others—such as maintenance managers—energy management skills are simply one more area to cover in an already full plate of duties and expectations.
The authors are writing this Energy Management Handbook for both of these groups of readers and users. Reply Toggle Dropdown Quote.

Are you sure you want to Yes No. Be the first to like this. No Downloads. List of Energy Measuring Instruments Location of installation workshop. To be done effetively a manager needs to: Designating staff members to implement energy measurement is important to creating an effective system.
Equipment is problematic if it: Companies should measure energy consumption by taking into account: The tests should be carried out on as many pieces of equipment as possible so managers can gauge the overall energy needs of the company. Energy consumption of power lines and departments Energy consumption of office and production equipment. It is important for managers to hire experts to conduct regular energy efficiency tests on equipment that uses high amounts of energy See Table Table Limits of power consumption or power of main energy-consuming equipment Energy type Unit Limit Crude oil.
Systems require modification to make them more energy efficient. Improper service maintenance and operation. Managers may be biased if low equipment efficiency is due to bad management yet it is difficult to evaluate the investment return of such tests.
Managers should also evaluate equipment that is not yet outdated to determine its energy efficiency based on national and international standards. Low operating efficiency is caused by: Potential challenges to conducting energy efficiency tests Tests are expensive because they have to be conducted by experts and senior executives might be reluctant to replace equipment if there is insufficient data.
Energy Diagnosis Methods 3. Many companies are unwilling to retire old and outdated equipment. Conduct a systematic production process analysis. This will save the company kWh of power RMB every day. Auxiliary energy consumption energy-saving solutions: Case study of an electronics factory At an assembly workshop in an electronics factory. Maintain higher productivity levels with the aim of completing production in six hours rather than eight.
Improve energy management. Reducing any of these three types of consumption would reduce overall energy consumption. The remaining hours can be used to train operators. To correct efficiency problems managers should: This is largely because the workshop runs 8-hour shifts even though productivity is low and there are insufficient orders. Common energy-saving solutions: Switch to night shifts as this could help reduce air-conditioning costs. After the valve was fully opened.
A patrol team can be set up to identify energy waste throughout the company.
For example. The investment was paid back in half a year. The aim is to identify energy-saving opportunities by identifying how different sets of electrical systems function together. From an efficiency point of view. Equipment that consumes energy during non-working hours. The disadvantage of using this method is that testing requires advanced technical equipment and high-level technical expertise.
Although appearing stable. How can companies reduce energy waste through better management? Case study: Waste water Treatment Plant Pump A pump in a wastewater treatment plant motor power: Please see the case study below. All kinds of leakage. Times when production capacity falls below equipment capacity. They can do this by using a classification method. Equipment manufacturers often fail to consider energy saving in their designs.
This aims to optimize production processes by measuring areas where the company wastes energy. Why process energy saving has the highest effect: To reach the terminal. A food processing plant. Excessive use of heat or pressure. Unnecessarily low temperatures.
Philosophy for process energy savings: Any energy supply with unnecessary output. To implement this process. Use a team of engineers to control energy flows through production systems. As energy flows from higher temperatures to lower temperatures. One well-known company. In most cases. Process energy saving is a low cost way of improving the quality of products. This is where frequency conversion technology comes in to play.
To enhance energy saving on equipment. Equipment maintenance is thus vital and should take place on a regular basis. Frequency Conversion Devices Equipment that has a driver motor can reach its intrinsic efficiency only when it runs under conditions for which it was ideally designed.
The example below demonstrates this point. As an alternative to replacing equipment. One company found a filter in a compressed air system was blocked. Although doing this saves energy to some extent. When selecting equipment. Consider adding a frequency converter see side bar to increase the frequency cycle of fans or pumps operating in alow efficiency zone. Frequency conversion technology can make fluid machines run close to their design efficiency. The air generated by the compressor.
A company invested RMB The new system reduced power consumption by kWh and saved the company RMB 5. In contrast. AC has two kinds of energy: Power Factor The power factor of an alternating current AC electric power system is defined as the ratio of the real power flowing to the load to the apparent power in the circuit. AC is converted into magnetic field energy and then back to electric power. Enhancing equipment and distribution efficiency ensures higher energy savings and reduces power used during the distribution process.
Technical apparatus can be used to test motors and circuits to determine the optimal power factor of each load. It appears redundant when compared with active power. The recommended power factor is below 0. To draw a power triangle requires using apparent power S. It is a dimensionless number between 0 and 1. The unit of reactive power is "var" or "kilovar" and the unit of apparent power is "VA" or "kVA".
Power Distribution Systems 1. Select energy-saving transformers S11 to reduce the amount of no-load currents and reactive power losses. Reducing reactive currents and increasing the power factor of a line is an effective way of reducing energy waste. In the case of a transformer network. This subsequently increased the factor to 0. By increasing voltage by 10 percent.
An increase of the operating voltage helps to improve power quality and reduce line loss. At a constant voltage and current. The load rate of a standalone transformer should be 70 to 80 percent. Considering the large amount of data and calculation required to determine the economic current density.
A chemical factory. To increase the load. The economic current density is closely related to the annual operating hours of cables. Adjust or replace transformers according to the actual load rate. The initial requirements were 1. Improving energy-saving processes.
Over-illumination in office buildings due to poor lighting system design. Under-illumination due to dusty light bulbs. Lighting Systems 2. Identify the best ways to use illumination.
Problems frequently found in lighting systems include: In many cases. Insufficient use of natural light. Decide on the illuminance.
Places requiring medium-level visibility. Work areas. Step 3: Use energy-saving lighting equipment and controls. Places requiring low-level visibility. Places requiring high-level visibility. Step 2: Based on decisions made in Step 1. Spaces before elevators. For instance. Add additional lighting when an illuminance of over lux is required.
But a comparative analysis of different kinds of lamps with the same luminance is essential. The lights in the factory and the corridor and product transfer areas cannot be switched off independently. To reduce the energy consumption of fluorescent lighting. Energy-saving ballasts The energy consumption of a fluorescent lamp equals includes the consumption of ballast.
Management methods include: Reflective covers can reflect light from a lamp to other areas where lighting is needed. Lighting system is in a large-scale electronics factory The production lines in the factory are located close to windows.
Install a switch that controls the lighting of the two lines of lamps close to the windows. Reduce the number of lamps to Install five switches to control the lighting in product transfer areas. A total of lamps are eliminated. Inspection area: Assembly area: Path Assembly Inspection Fig. Electric ballasts have been installed for energy saving 1 Divide the workshop into three functional areas.
Install reflecting covers to compensate for the decrease of illuminance in peripheral areas. Lighting in this area can be switched off when no one is working there. The number of lamps remains the same.
These lamps can be switched off during the day.. Use LED lamps in inspection areas to protect the eyesight of workers. Energy-saving measures include: As one of the most widely used power sources in industrial production.
Compressed Air Systems 3. The figure below illustrates the total cost of compressed air over a 10 year period. In most factories. Examples of air supply equipment include air compressors. Given that the efficiency of motor systems in China is 20 percent lower than that of most developed countries. China-based SMEs have the opportunity to reach energy savings of up to 40 percent. Compressed air is possibly the most expensive form of energy.
If a pipeline is thermo-insulated and it is used at the same level of temperature as when the compressed air leaves the compressor outlet. Note that this calculation is theoretical and does not account for additional losses.
It is difficult to achieve this. In general. In other words. They are usually used as surface filters. Selecting a pipe size: They have the same filtration mechanism as that of other thickParticle filters can be used to remove dust in dry air from outside to inside. Pressure drop occurs in compressed air systems when pressure moving from the compressor outlet to the terminal unit declines.
They are suitable for indepth filtration. Mini-filter Mini-filters can move 0. Any sort of obstruction or roughness in the distribution pipeline will cause resistance to the air flow. Air distribution systems supply air into terminal units. Excessively small pipes result in resistance to the air flow.
Air supply side Operating range of compressor Pressure drop of after cooler. Even a well-designed pipeline can experience a sudden decrease in pressure after the installation of a new terminal unit.
To deal with this problem. Increase of cost:
