27、trols,manufacturers can reduce their overall energy consumption,resulting in lower utility bills.In addition,energy-efficient machines often last longer and require less maintenance,reducing downtime and costs for repairs.According to IEA,most EEMs in its Net Zero Scenario are already cost-effective
28、,meaning that the energy cost savings are greater than the investment required.6 According to the US Department of Energy,the average energy cost savings identified by an energy-efficiency audit of a single energy-intensive system within a manufacturing company is US$1.4 million;for small and midsiz

64、h systems and processes will be evaluated is essential for a successful energy audit.Depending on the facilitys needs,energy assessments can vary in scope and depth,ranging from quick assessments that identify major opportunities,to detailed assessments of specific systems(e.g.,HVAC,CDA,lighting),or
65、 comprehensive plant-wide audits.While quick or system-specific assessments may be appropriate in certain situations,a plant-wide energy audit is highly recommended whenever possible.This comprehensive approach not only measures the energy consumption of individual systems but also maps the energy f
66、low between different components within the facility,uncovering broader opportunities for efficiency improvements.By analyzing the interactions between systems,the audit can identify additional energy-saving opportunities that might otherwise be overlooked.For instance,assessing the potential for he
67、at recovery and reuse between production processes and HVAC systems can reveal significant efficiency gains that would be missed if the HVAC or production systems were audited separately.A facility-wide audit also ensures that energy losses at system boundaries are captured and that the potential sy
68、nergies among various processes such as using waste heat from CDA systems for water heating are fully realized.In addition,after completing the energy audit,it is essential to establish clear,actionable goals for the energy-efficiency project.These goals should be designed to not only achieve energy
69、 and cost savings but also to deliver broader,lasting benefits to the facility and organization.Key advantages of such goals include enhancing the companys financial stability and improving its competitive position.Moreover,the energy-efficiency project should be implemented in a manner that maintai

77、)the potential energy savings of each measure,(2)the payback period to determine whether the investment is financially viable,and(3)the operational impact to ensure that the measures minimally affect the production processes.By carefully evaluating these aspects,FATP facility owners can make informe

97、e HVAC system is another major energy consumer in FATP facilities,typically accounting for approximately 30%of total electricity consumption.This figure can escalate considerably if the system is not properly configured and controlled.The HVAC system is crucial for maintaining optimal environmental
98、conditions within the facility,such as temperature,humidity,and air quality,which are essential for ensuring the reliability and quality of production processes.Given the HVAC systems significant energy use and critical role in production,it is important to implement key EEMs for each subsystem(see
99、Exhibit 8,page 16).1.Chiller:The chiller is a pivotal component of the HVAC system,significantly influencing overall energy efficiency.Upgrading from low-efficiency to high-efficiency chillers can substantially improve system performance,although the initial investment may result in a payback period
100、 ranging from two to over ten years.Conversely,regular cleaning of heat exchangers is a cost-effective measure that generally yields a payback period of less than two years.Additionally,selecting chillers with low global warming potential and ozone-depleting potential helps reduce life-cycle environ
101、mental impacts.2.Chilled and cooling water system:Over 20%of HVAC energy consumption is allocated to water transmission.Implementing straightforward and economical EEMs,such as insulating pipelines,increasing chilled water temperatures,and making hydraulic adjustments,can enhance efficiency.Addition
102、ally,using cooling towers for free cooling during colder months proves to be highly cost-effective,with a payback period of under two years.Upgrading to efficient VFDs for pumps typically results in a payback period of less than three years.3.Air-handling system:The air-handling system is particular
103、ly energy-intensive because of the stringent air-quality requirements necessary for electronics manufacturing.Cost-effective EEMs,including adjusting fresh air intake,regularly cleaning or replacing coils,and upgrading fan-filter units(FFUs)from AC to DC motors,usually offer a payback period of less
104、 than two years.Although exhaust-air heat recovery can be highly beneficial,the payback period may extend to four years or more,depending on specific conditions.Replacing steam humidifiers with spray or ultrasonic humidifiers is another effective measure,with a payback period of less than three year
105、s.4.Control system:In FATP facilities,where cooling demands fluctuate and system interactions are complex,the control system is essential for optimizing component efficiency and adapting to real-time needs.Installing VFDs on pumps and fans and employing time switches to reduce operational hours are
106、straightforward measures with a typical payback period of under three years.Although implementing centralized control through an EMS involves a higher level of complexity,it can greatly optimize HVAC operations across the facility,offering a payback period of less than two years because of significa
107、nt energy savings.5.Boilers:FATP facilities in colder climates often use boilers for space and water heating.Recovering waste heat from these systems can result in significant energy savings,provided that suitable heat sinks,such as dormitories or low-temperature processes,are identified for effecti
108、ve use.Other EEMs for boilers include installing flue gas sensors and controls to optimize combustion and replacing leaking steam traps.Improving boiler efficiency can reduce energy consumption by up to 30%,with payback periods of less than two years.Furthermore,transitioning from fossil-fueled boil
109、ers to electric heat pumps can significantly lower direct CO2 emissions and provide additional benefits,such as reduced local air pollution(SOx,NOx)and lower insurance costs.Thanks to the excellent energy efficiency of heat pumps and the decreasing electricity prices relative to fossil fuels,the ini

116、ciency in manufacturing facilitiesProduction systemThe production process accounts for approximately 30%of total electricity consumption for FATP facilities.This process is critical as it has a direct impact on the manufacture of electronic components and the overall efficiency of manufacturing oper
117、ations.However,the implementation of EEMs in this area is often driven by OEM specifications,which limit the flexibility of suppliers to make changes.In addition,because much of the energy consumption in this process is closely tied to production activities,introducing EEMs could disrupt operations
118、or introduce uncertainty.Despite these challenges,several strategies can improve energy efficiency in the manufacturing process(see Exhibit 9,page 18).Standby mode optimization:Production processes are not continuous,and research shows that 30%of energy consumption by machine tools comes from standb
119、y operation during production pauses or equipment idle periods.9 Optimized energy-saving modes can help avoid unnecessary energy waste by automatically reducing power consumption when equipment is not in active use.This measure is highly cost-effective,as it typically requires little to no up-front
120、investment while delivering immediate energy savings.Insulation:Many production processes generate excess heat that is often lost to the environment.Properly insulating equipment and heat-emitting areas helps retain this heat,reducing the workload on HVAC systems.This measure requires minimal up-fro
121、nt investment while delivering considerable energy savings;the payback period is typically less than six months.Process automation:Process automation can enhance overall efficiency by optimizing workflows,reducing manual intervention,and minimizing energy use across various stages of production.For
122、instance,replacing pneumatic systems with servo motors could offer greater precision and efficiency,as well as reduce the CDA systems energy consumption.Although automation requires up-front investment,the energy savings,along with improved productivity and reduced manual labor costs,result in a hig

142、 on the following three key aspects:Strategically sequence the EEMs:Start by implementing simple and proven measures that are typically easy and cost-effective,providing quick wins and establishing a solid foundation for more complex upgrades.Find the right time for hard-to-implement projects:Schedu
143、le EEMs that require longer installation times and may disrupt production during periods that minimize production downtime,such as public holidays.Introducing high-efficiency equipment toward the end of the current product life cycle can maximize economic returns.Aligning new product introductions w
