Potential motor-driven system energy savings can be realized by using mature, proven, and cost-effective technologies. Improved energy efficiency also leads to reduced environmental emissions. This paper promotes a systems approach to increase the energy efficiency in mine ventilation.

Several energy management standards currently exist (Denmark, Ireland, Sweden, United States) and others are planned (China). This issues paper presents the current status of energy management standards development internationally, including an analysis of their shared features and differences, in terms of content, promulgation, and implementation. The purpose of the analysis is to describe the current state of "best practices" for this emerging area of energy efficiency policymaking and to suggest next steps toward the creation of a truly international energy management standard that is consistent with the ISO principles of measurement, documentation, and continuous improvement.

The International Energy Agency estimates thatoptimizing motor systems results in an improvement of 20-25 percent,which is well-supported by experience in both the U.S. and China.Compressed air systems in China use 9.4 percent of all electricity.Compressed air use in China is growing rapidly, as new industrial plantsare built and the production processes of existing plants expand andchange. Most of these systems, whether existing or new, are not optimizedfor energy efficiency. This paper will present a practitioner'sperspective on theemergence of compressed air auditing services inChina, specifically as it pertains to Shanghai and surrounding areas.Both the methodology used and the market development of these compressedair system services will be addressed.

The Challenge began as a voluntary collaboration managed by a sponsor, the Energy Center of Wisconsin, that included 15 sponsors from equipment manufacturers and distributors ’ associations, utilities, state research and development agencies, energy efficiency organizations, and the USDOE. The mission of the CAC is to develop and provide resources that educate industry on the opportunities and benefits attainable through compressed air system optimization. In 2000, the CAC became an independent not-for-profit organization that continues a development and deployment model based on shared interests and shared costs among public, private, and not-for-profit organizations that serve industrial customers. Since the first CAC training session in 1999, approximately 3900 people have been trained by CAC qualified instructors- both end users and suppliers. Using the CAC cost-share model has allowed sponsors to offer a very high-quality training product at a relatively low cost. For instance, USDOE typically spends 1foreach1 for each 1foreach10 spent to offer a CAC training session. This paper will summarize the findings of two recent independent evaluations were conducted by USDOE to assess the impact of CAC training and the market for compressed air efficiency services. One significant

Pumping systems account for an estimated25 percent of this electrical motor consumption, while pumping systems inuse in US chemical facilities consume over 37,000 GWh/year, based on USDepartment of Energy (DOE) data.

If optimized, the efficiency of most industrial motors systems in China could be improved by 20% or more. In response to this opportunity, China established the China Motor Systems Energy Conservation Program in late 2001 in cooperation with the United Nations Industrial Development Organization, the US Department of Energy, and the Energy Foun- dation. A previous paper described progress at the mid-point of this 3-year pilot program in Jiangsu and Shanghai provinces. This paper presents the final results of the pilot program, as documented in case studies, completed projects, plant assessments, and training activities and through a final independent program evaluation. The focus is on the overall efficacy of transferring complex sys- tem optimization techniques across languages and cultures using the pilot program model of class- room instructi...

To reduce energy consumption, steam system energy assessments have been conducted on a wide range of industry types over the course of 5 years through the Energy Savings Assessment (ESA) program administered by the US Department of Energy (US DOE). ESA energy assessments result in energy efficiency measure recommendations that are given potential energy and energy cost savings and potential implementation cost values. Saving and cost metrics that measure the impact recommended measures will have at facilities, described as percentages of facility baseline energy and energy cost, are developed from ESA data and used in analyses. Developed savings and cost metrics are examined along with implementation and rejection rates of recommended steam system energy efficiency measures. Based on analyses, implementation of steam system energy efficiency measures is driven primarily by cost metrics: payback period and measure implementation cost as a percentage of facility baseline energy cost (implementation cost percentage). Stated reasons for rejecting recommended measures are primarily based upon economic concerns. Additionally, implementation rates of measures are not only functions of savings and cost metrics, but time as well.

These systems account for nearly 20 percent of theworld's industrial electrical energy demand and range from 25-50 percentof the energy usage in certain industrial plant operations. Purchasedecisions for a pump and its related system components are typicallybased upon a low bid, rather than the cost to operate the system over itslifetime.

Despite these opportunities, many industrial facilities continue to have unrealized system optimization potential. A significant barrier to realizing this potential is the lack of market definition for system energy efficiency assessment services. This creates problems for service providers in establishing market value for their services and problems for consumers in determining the relative quality of assessment service offerings. Achieving certification for energy efficiency will require industrial facilities to document a specified reduction in energy intensity. Application of System Assessment Standards will offer industrial facilities seeking certification a well-defined path toward improved energy intensity. System Assessment Standards will help define the market for both users and providers of industrial system assessment services. Use of t...
