6.1 This practice is intended to serve as a concise, authoritative, and technically sound practice for Building Enclosure Commissioning (BECx) that is based upon:6.1.1 The Owner Project Requirements;6.1.2 Clearly defined and enforceable levels of BECx; and6.1.3 Minimum core competencies required of the BECxP and associated service-providers28 (see 4.2) to qualify as Fundamental or Enhanced BECx under this practice.6.2 This practice is suitable for use as an independently applied standard for new buildings and structures, or as part of a more broadly based Total (or “Whole”) Building Commissioning Program.1.1 This practice is intended to serve as a concise, authoritative, and technically sound practice for Building Enclosure Commissioning (BECx) that establishes two levels of BECx: Fundamental and Enhanced (refer also to Section 4).1.2 The BECx process as defined in this practice includes the following phases and sub-phases:1.2.1 Pre-design,1.2.2 Design,1.2.2.1 Schematic Design,1.2.2.2 Design Development,1.2.2.3 Construction Documentation,1.2.3 Bidding and Negotiation Phase,1.2.4 Construction,1.2.4.1 Pre-Construction,1.2.4.2 Construction Administration, and1.2.5 Occupancy and Operations.1.3 This practice includes a mandatory OPR Development Guideline (Annex A1) and requires the development of an OPR for both Fundamental and Enhanced BECx that addresses, at a minimum, the performance attributes and metrics included in Annex A1 of this practice.1.4 This practice includes mandatory BECx Performance Testing Requirements (Annex A2) approved for use with this practice to evaluate the performance and durability of enclosure materials, components, systems, and assemblies.1.5 This practice mandates independent design review during the Design Phase of both Fundamental and Enhanced BECx.1.6 This practice recognizes that the OPR for exterior enclosure performance and environmental separation may exceed the baseline requirements of applicable building codes and standards and provides guidance for the development of an OPR based on the following attributes as defined in Annex A1 of this practice:1.6.1 Energy,1.6.2 Environment,1.6.3 Safety,1.6.4 Security,1.6.5 Durability,1.6.6 Sustainability, and1.6.7 Operation.1.7 The terms “building enclosure” and “enclosure” as they appear in this practice refer collectively to all materials, components, systems, and assemblies intended to provide shelter and environmental separation between interior and exterior, or between two or more environmentally distinct interior spaces in a building or structure.1.8 This practice establishes that the Building Enclosure Commissioning Provider (BECxP) refers specifically to the individual retained by the Owner to develop, manage, and be in responsible charge of the BECx process, including individual members and technical specialists that may comprise the BECx group (see 4.2).1.9 The role and responsibilities of the BECxP as defined by this practice are not intended to supersede or otherwise replace the contractual obligations reserved specifically for the parties responsible for the design and construction of a building or structure, nor the duties that may otherwise be assigned to those parties by applicable regulatory or statutory law.1.10 This practice is not intended to warrant or otherwise guarantee the as-built or in-service durability, or both, and performance of enclosure materials, components, systems, and assemblies.1.11 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.1.12 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.1.13 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.

5.1 This guide is meant to be used with and applied to individual trained descriptive assessors.5.2 The procedures recommended in this guide can be used by the panel leader to periodically appraise the performance of individual descriptive assessors.5.3 Tracking assessor performance will provide information as to the quality of the data being generated. Performance information may be used to decide whether to use the data to interpret product profiles.5.4 Monitoring assessor performance will enable the panel leader to identify retraining needs or to identify assessors who are not performing well enough to continue participating on a panel.1.1 This guide provides guidelines for measuring and tracking the performance of individual assessors on a descriptive sensory panel.1.2 This guide provides guidelines to assist sensory professionals in measuring performance for given assessors. Measuring performance will form the basis for (1) determining the reliability of the results, and (2) establishing remedial actions for an individual assessor.1.3 This guide examines various aspects of trained assessor performance; such as repeatability, discrimination, and agreement and demonstrates some ways to measure them. The procedures will help the sensory professional determine areas of good performance as well as those that require improvement.1.4 Individual assessor performance is tracked using established statistical procedures. These procedures depend on whether replicates are collected and if they are collected over multiple sessions or within a single session.1.5 This guide provides suggested procedures, including statistical procedures that can be done using standard statistical software, for evaluating performance and is not meant to exclude other methods that may be effectively used for a similar purpose.1.6 Methods for training and screening assessors are not within the scope of this guide. This guide does not address how to communicate performance feedback information to individual assessors. This monitoring of panel reproducibility, a measure of the panel’s ability to reproduce the results of other panels, is also not within the scope of this guide.1.7 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.1.8 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.
