2、ms. ASABE Standards are consensus documents developed and adopted by the American Society of Agricultural and Biological Engineers to meet standardization needs within the scope of the Society; principally agricultural field equipment, farmstead equipment, structures, soil and water resource managem

3、ent, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management. NOTE: ASABE Standards, Engineering Practices, and Data are informational and advisory only. Their use by anyone engaged in industry or

4、 trade is entirely voluntary. The ASABE assumes no responsibility for results attributable to the application of ASABE Standards, Engineering Practices, and Data. Conformity does not ensure compliance with applicable ordinances, laws and regulations. Prospective users are responsible for protecting

5、themselves against liability for infringement of patents. ASABE Standards, Engineering Practices, and Data initially approved prior to the society name change in July of 2005 are designated as “ASAE“, regardless of the revision approval date. Newly developed Standards, Engineering Practices and Data

6、 approved after July of 2005 are designated as “ASABE“. Standards designated as “ANSI“ are American National Standards as are all ISO adoptions published by ASABE. Adoption as an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other crit

7、eria for approval have been met by ASABE. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unan

8、imity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at any time. Additionally, procedures of ASABE require that action be taken periodically to reaffir

9、m, revise, or withdraw each standard. Copyright American Society of Agricultural and Biological Engineers. All rights reserved.

10、cultural and Biological Engineers 1 ANSI/ASABE S612 JUL2009 (R2015) Approved July 2009 as an American National Standard Performing On-farm Energy Audits Developed by ASABE with the cooperation of USDA NRCS. Approved by cross division representation of the society under the guidance of T-11, Energy,

11、and approval of T-01, Standards (Policy reaffirmed December 2015; reaffirmed by ANSI December 2015. Keywords: Audit, Costs, Efficiency, Energy, Management 1 Purpose 1.1 This Standard establishes procedures for performing on-farm audits to determine and document current energy usage, and to provide a

12、n estimation of energy savings from alternatives in the cultivation, protection, harvesting, processing and storage of agricultural commodities and in the feeding, housing and processing of farm animals and animal products. This Standard is provided to guide the reporting of data and the preparation

13、 of specific recommendations for energy reduction and conservation with estimates of energy savings. 2 Scope 2.1 This Standard is intended to support energy audits of all types of farming operations (which includes ranching) typically found in North America. Energy audits shall exclude the farm resi

14、dence, except where it is not practical to separate base line data. 2.2 This Standard does not address secondary (off-farm) energy savings in the development and evaluation of alternatives. For example, reduction in the amount of fertilizer used on a farm would represent a reduction of the associate

15、d energy needed to produce fertilizer for the farm at a fertilizer production facility (off-farm). This type of energy savings is not addressed as a part of this Standard. 3 Definitions 3.1 energy: For the purposes of this Standard energy is the resource used to power equipment to do mechanical work

16、 or to generate heat, light or cooling. 3.2 energy resource: Source from which energy is obtained, including gasoline, diesel fuel, biofuel, propane, natural gas, electricity, solar, wind, wood, biomass, geothermal, etc. 3.3 farm enterprise: Production category of a farm. For example, a farm may inc

17、lude a field crop enterprise and a livestock enterprise (see Table 1). 3.4 major activity: A discrete activity associated with a farm enterprise that utilizes an energy resource, or that heavily impacts energy resource use. For example, a cropping enterprise may include grain drying, crop planting,

18、tilling, and harvesting activities (see Table 1). 3.5 component: Individual parts of a major activity. For example: lighting systems include lamps, ballasts, timers, sensors, etc. (see Table 1). 3.6 energy auditor: A licensed professional engineer or other technically qualified individual who will c

19、ertify that the audit report provided to the farmer/rancher meets the requirements outlined in ASABE S612.

38、t reports shall contain a certification statement that the auditor(s) possess the technical expertise and experience to perform on-farm energy audits, and that the audit report meets all requirements in ASABE Standard S612. (See informative annex A.) Annex A (informative) Commentary This Annex provi

39、des additional information and explanation of considerations used in developing this Standard. Documentation: The Standard provides flexibility in how audit reports are developed and documented. The Standard only addresses the minimum requirements for documentation that would provide for sufficient

40、information from which the farm operator could make informed decisions. However, greater documentation is encouraged to provide as complete a supporting case file as is practical. This documentation may not be included in the report provided the farm operator, but should be maintained in a case file

41、. It is suggested that for each alternative major activity component an appropriate reference be included that would support recommendations for improving energy efficiency. Assessments: In determining the economy of various energy use activities on a farm, it is important to consider potential incr

42、eases in product as part of the benefit used in the analysis. It is recognized that sometimes an increase in energy use will facilitate greater production on-farm (i.e., larger ventilation fans in poultry houses, that provide for healthier bird production), thereby increasing the benefit to cost rel

43、ationship. Therefore, it could be appropriate to consider these factors in the energy use assessment and determinations of changes in efficiency. This evaluation is sometimes referred to as “energy density unit calculations.” Also, it was assumed in the crafting of paragraph 5.3.2 that changes in en

44、ergy management (i.e., timing of power demand to off-peak times; or sequential starting of large motors) should be addressed as a “savings of energy cost” even though it does not necessarily represent a saving in overall energy consumption. Furthermore, it is recognized that the standard does not id

45、entify specific procedures for performing various audit functions associated with the major activities and their associated components. Other standards exist that provide this function, that were too numerous to reference specifically; however, it is recommended that recognized standards (ASABE, AWW

46、A, ASTM, etc.) be used whenever possible. Renewable Energy: The developers of this Standard recognize that in some situations conversion to a renewable energy resource may be a practical alternative to present to a farm operator. It is also recognized that the use of renewable energy resources shoul

47、d be encouraged whenever possible. However, the intent of this Standard is not to facilitate a reduction in non-renewable energy resources, but rather to provide a method to facilitate increased efficiency in the use of whatever energy resources are being used. Certification: Ideally, there would be

48、 a process in-place, provided by non-profit, State, or National entities, for certification of on-farm energy auditors. This certification could be referenced as a requirement for performing on-farm energy audits to add credibility to individuals wishing to perform such audits. There are certificati

49、ons and licensing processes that do provide a level of assurance that an individual is qualified, if only ethically bound, to perform the audits described in this Standard, such as licensed engineers, Association of Energy Engineers ANSI/ASABE S612 JUL2009 (R2015) Copyright American Society of Agricultural and Biological Engineers 5 (AEE) Certified Energy Managers (CEM), the Association of Energy Engineers Certified Energy Auditor (CEA), or state certified/licensed farm energy auditors.
