1.1 Purpose—The purpose of this standard is to define a commercially useful practice in the United States of America for conducting a building energy performance assessment (BEPA) on a building involved in a commercial real estate transaction and subsequent reporting of the building energy performance information. The practice is intended to provide a methodology to the user for the collection, compilation, analysis, and reporting of building energy performance information associated with a commercial building. The practice may be used independently or as a voluntary supplement to Guide E2018 for property condition assessments or Practice E1527 for Phase I environmental site assessments. Utilization of this practice and performance of a BEPA is voluntary. If the property owner (for example, the seller) is unwilling or unable to provide building energy consumption and cost information, a BEPA cannot be performed.

1.2 Building Energy Performance—This practice defines building energy performance as the building’s total annual energy consumption and cost for heating, cooling, electricity, and other related uses. Energy consumption, for example, includes total electricity purchased; purchased or delivered steam, hot water, or chilled water; natural gas; fuel oil; coal; propane; biomass; or any other matter consumed as fuel and any electricity generated on site from renewable/alternative energy systems (for example, wind energy generator technology, fuel cells, microturbines or solar photovoltaic systems).

1.3 Objectives—Objectives in the development of this practice are to: (1) define a commercially useful practice for collecting, compiling, and analyzing building energy performance information associated with a building involved in a commercial real estate transaction; (2) facilitate consistency in the collection, compilation, analysis, and reporting of building energy performance information as may be required under building benchmarking, labeling, disclosure, or mandatory auditing regulations; (3) supplement as needed a property condition assessment conducted in accordance with Guide E2018 or an environmental site assessment conducted in accordance with Practice E1527; (4) provide that the process for building energy performance data collection, compilation, analysis, and reporting is consistent, transparent, practical and reasonable; and (5) provide an industry standard for the conduct of a BEPA on a building involved in a commercial real estate transaction, subject to existing statutes and regulations which may differ in terms of scope and practice.

1.4 Documentation—The scope of this practice includes data collection, compilation and reporting requirements. Documentation of all sources, records, and resources relied upon in the investigation is provided in the report.

1.5 Considerations Outside the Scope—The use of this practice is limited to the collection, compilation, and analysis of building energy performance information as defined by this practice for real estate transactions in the United States of America. While this information may be used to facilitate building benchmarking, labeling, rating or ranking, reporting of building energy performance information between a seller and a buyer or a landlord and a tenant on a voluntary basis or as may be required by building benchmarking, labeling, disclosure or mandatory auditing regulations applicable to the building, or any other use, such use is beyond the scope of this practice. This ASTM Standard Practice does not supersede existing statutes and regulations.

1.6 Organization of This Practice—This practice has 13 sections and 11 appendices. The appendices are included for informational purposes only and are not part of the procedures prescribed in this practice.

1.7 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.8 This practice cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard practice is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this practice be applied without consideration of a building’s many unique aspects. The word “standard” in the title means only that the practice has been approved through the ASTM consensus process.

1.9 Nothing in this practice is intended to create or imply the existence of a legal obligation for reporting of energy, performance, or other building-related information. Any consideration of whether such an obligation exists under any federal, state, local, or common law is beyond the scope of this practice.

1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Uses—This practice is intended for use on a voluntary basis by parties who wish to conduct a BEPA on a building. The process defined in this practice involves the collection of building energy consumption information, some of which may be collected as part of E2018 PCA or E1527 ESA. The practice is intended primarily as an approach to conducting a standardized inquiry designed to identify representative building energy performance in connection with a commercial property involved in a real estate transaction. This practice is intended to reflect a commercially practical and reasonable inquiry.

4.2 Clarifications on Use: 

4.3 Who May Conduct—A BEPA shall be performed by a qualified consultant or individual (hereafter referred to as the “Consultant”) with the education, training and experience necessary to perform the requirements of this practice (see Appendix X4). No practical approach can be designed to eliminate the role of professional judgment and the value and need for experience in the individual performing the inquiry. The professional experience of the Consultant is, consequently, important to the performance of this BEPA.

4.4 Additional Services—As set forth in Section 13, additional services may be contracted for between the user and the Consultant. Such additional services may include issues not included within the scope of this practice. For example, the user or Consultant may wish to benchmark the building against similar buildings in the portfolio or in the same geographical area or identify select green building attributes that may contribute to the energy efficiency performance and/or the building’s valuation.

4.5 Principles—The following principles are an integral part of this practice and are intended to be referred to in resolving any ambiguity or exercising such discretion as is accorded the user or Consultant in performing a BEPA.

4.6 Rules of Engagement—The contractual and legal obligations between a Consultant and a user (and other parties, if any) are outside the scope of this practice. No specific legal relationship between the Consultant and user was considered during the preparation of this practice.
