5.1 This guide provides recommendations for the enclosure commissioning process from its project planning through design, construction and occupancy and operation phases. This guide is intended for various building types. Although Practice E2813 defines two levels of enclosure commissioning, fundamental and enhanced, complex buildings and Owners seeking a higher level of assurance may require more intensified enclosure commissioning than the minimum requirements described in this guide and Practice E2813.135.2 The process uses performance-oriented practices and procedures to verify that the project is achieving the expectations described in the OPR and defined by the contract documents throughout the delivery of the project.5.3 The BECx process is recommended to begin during the pre-design phase and continues through the occupancy and operations phase. The process includes specific tasks during each project phase.5.4 The commissioning process is outlined in ANSI/ASHRAE/IES Standard 202. It is recommended that the reader understand the process provided in that document. This standard guide and Practice E2813 provide a specific process related to the building enclosure commissioning.5.5 Note that the enclosure commissioning process should not infringe upon the authority or responsibility of the Owner, the project’s designers or contractors. The CxG and BECxG can identify areas of concern relative to the OPR, which are discussed with the Owner and other stakeholders; however it is the Owner who directs the project, Cx team, and BECx team. It is recommended that the BECxP be engaged in pre-design phase to define the scope of BECx so that the Owner’s agreements with the project team (including the contractor) clearly define the scope of contracted tasks that interface with BECx process.5.6 BECx does not replace a traditional design/construction process but is meant to enhance and be an integral part of that process by validating the design and verifying the construction meets the requirements described in the OPR and defined by the contract documents.5.7 In this guide, the performance objectives for attributes of the building enclosure as required by an Owner are considered. Enclosure attributes to be considered include the control of moisture, condensation, heat flow, air flow, water vapor flow, noise, fire, vibrations, energy, light, infrared radiation (IR), ultraviolet radiation (UV), as well as the structural performance, durability, resiliency, security, reliability, aesthetics, value, constructability, maintainability over its life cycle, and sustainability of the enclosure elements to meet or exceed the expectations described in the OPR and defined by the contract documents. The commissioning objectives for a building’s enclosure may vary by the Owner’s requirements. The objectives contained in the OPR may vary by occupancy, use, size, and the project requirements, which may include other requirements across these or other variables.5.7.1 Note that this guide is not a one-size-fits-all “how to” standard guide on avoiding poorly performing building enclosures.5.8 Approach: 5.8.1 The sequence of work for the BECx team commences by assembling the documentation of the OPR at the inception of a project. The sequence continues with the conveyance and interpretation of this information by the BECxG throughout the building delivery process. Throughout the process, the BECxP verifies that the BECxG’s work product is consistent with this guide and Practice E2813. The BECx process has been structured to coincide with the phases of a generic project with pre-design, design, bidding and negotiation, construction, occupancy, and operations phases. If circumstances require Owners to adopt the BECx process during the design or construction phase of a project, implementation at that point in time shall capture the information that would have been developed had the BECx process begun at project inception. Beginning the BECx process at project inception will maximize benefits to the project.5.8.2 Although this guide focuses upon building enclosure systems, a successful whole building commissioning process should carefully document and verify interfaces between interdependent building systems. Even if the building enclosure is the singular focus of this Cx process, coordination among disciplines is essential for overall building project success.1.1 Purpose—This guide provides procedures, methods and documentation techniques that may be used in the application of the building enclosure commissioning (BECx) process. This guide is complementary to Practice E2813 and is aligned with ANSI/ASHRAE/IES Standard 202 and ASHRAE Guideline 0.1.2 Extent—The process outlined in this standard guide applies to each building delivery phase from pre-design through occupancy and operation. The specific application of this guide may vary to suit the Owner, the project delivery method and the building project as described in the Owner’s Project Requirements (OPR), and as defined by the contract documents.1.3 Primary Focus—The primary focus of this process includes, but may not be limited to, new construction of building enclosures, existing building enclosures undergoing substantial renovation or alteration, and continuous commissioning of enclosure systems.1.4 Contractual and Regulatory Obligations—The methods described in this guide 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 to alter the roles, responsibilities and duties that may otherwise be assigned to those parties by applicable regulatory or statutory law.1.5 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.1.6 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 This test method is intended to provide only comparative measurements of surface flame spread and smoke density measurements with that of select grade red oak and fiber-cement board surfaces under the specific fire exposure conditions described herein.4.2 This test method exposes a nominal 24-ft (7.32 m) long by 20-in. (508 mm) wide specimen to a controlled air flow and flaming fire exposure adjusted to spread the flame along the entire length of the select grade red oak specimen in 5 1/2 min.4.3 This test method does not provide for the following:4.3.1 Measurement of heat transmission through the tested surface.4.3.2 The effect of aggravated flame spread behavior of an assembly resulting from the proximity of combustible walls and ceilings.4.3.3 Classifying or defining a material as noncombustible, by means of a flame spread index by itself.1.1 This fire-test-response standard for the comparative surface burning behavior of building materials is applicable to exposed surfaces such as walls and ceilings. The test is conducted with the specimen in the ceiling position with the surface to be evaluated exposed face down to the ignition source. The material, product, or assembly shall be capable of being mounted in the test position during the test. Thus, the specimen shall either be self-supporting by its own structural quality, held in place by added supports along the test surface, or secured from the back side.1.2 Test Method E84 is a 10-min fire-test response method. The following standards address testing of materials in accordance with test methods that are applications or variations of the test method or apparatus used for Test Method E84:1.2.1 Materials required by the user to meet an extended 30-min duration tunnel test shall be tested in accordance with Test Method E2768.1.2.2 Wires and cables for use in air-handling spaces shall be tested in accordance with NFPA 262.1.2.3 Pneumatic tubing for control systems shall be tested in accordance with UL 1820.1.2.4 Combustible sprinkler piping shall be tested in accordance with UL 1887.1.2.5 Optical fiber and communications raceways for use in air handling spaces shall be tested in accordance with UL 2024.NOTE 1: Annex A13 includes additional information describing a standard other than those listed in this section that also utilizes a modification of the apparatus used for Test Method E84.1.3 The purpose of this test method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. Flame spread and smoke developed index are reported. However, there is not necessarily a relationship between these two measurements.1.4 The use of supporting materials on the underside of the test specimen has the ability to lower the flame spread index from those which might be obtained if the specimen could be tested without such support. These test results do not necessarily relate to indices obtained by testing materials without such support.1.5 Testing of materials that melt, drip, or delaminate to such a degree that the continuity of the flame front is destroyed, results in low flame spread indices that do not relate directly to indices obtained by testing materials that remain in place.1.6 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.7 The text of this standard references notes and footnotes that provide explanatory information. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of the standard.1.8 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions.1.9 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.1.10 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.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.

5.1 The impact strength values obtained on the flat sections of a building product profile are relevant only to the flat section that has been tested and these values do not necessarily indicate the impact resistance of the whole product, which is affected by the configuration of the profile (that is, corners, ribs, etc).5.2 Constant weight and variable height, employed in these test methods, allow the velocity of impact to vary and, therefore, by Procedure B, can determine the energy of ductile-to-brittle transition, which cannot be determined if a variable weight is dropped from a constant height.5.3 These test procedures have been found to be useful elements in rigid poly(vinyl chloride) (PVC) building product characterization. Compound qualification, finished product quality control, environmental and weatherability research and development studies, and fabrication tolerance prediction constitute useful applications.FIG. 2 Impact Tester5.4 Choice of the specific impactor head configuration used is related to a variety of product attributes, such as specimen thickness and product toughness as well as abstract factors, such as the anticipated mode of failure in a specific application. The geometric uniqueness of the impactor head configurations prevents any comparison or correlation of testing results on samples tested with differing impactor head configurations. In general, the conical impactor, C.125, is useful to ensure failure of thicker specimens where the H.25 impactor caused no failure.NOTE 2: Equivalent surface conditions are more likely to occur when specimens are prepared by compression molding or extrusion than by injection molding.5.5 When comparing different samples tested with the same impactor head configuration, impact resistance shall be permitted to be normalized for average specimen thickness over a reasonably broad range (for example, 1 to 3 mm).3 However, this should only be done when the surface conditions listed in 6.1 are essentially equivalent.1.1 These test methods cover the determination of the energy required to crack or break rigid poly(vinyl chloride) (PVC) plastic sheeting and profile flat sections used in building products, as well as extruded or molded test samples, under specified conditions of impact from a freefalling standard weight striking an impactor with either of two configurations in contact with the specimen.1.2 Two test procedures are included:1.2.1 Procedure A, used to determine minimum impact energy required to cause failure (hole, crack, split, shatter, or tear).1.2.2 Procedure B, used to determine minimum impact energy required to cause brittle failure.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.NOTE 1: There is no known ISO equivalent to this standard.1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding, those in tables in figures) shall not be considered as requirements of this standard.1.5 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. Specific precautionary statements are given in Section 8.1.6 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 This classification defines building elements as major components common to most buildings. The classification is the common thread linking activities and participants in a building project from initial planning through operations, maintenance, and disposal.4.2 The users of UNIFORMAT II include owners, developers, facilities programmers, cost planners, estimators, schedulers, architects and engineers, specification writers, operating and maintenance staff, manufacturers, and educators.4.3 Use this classification when doing the following:54.3.1 Structuring costs on an elemental basis for economic evaluations (Practices E917, E964, E1057, E1074, E1121, and E1804) early in the design process. Using UNIFORMAT II helps reduce the cost of early analysis and contributes to substantial design and operational savings before decisions have been made that limit options for potential savings.4.3.2 Estimating and controlling costs during planning, design, and construction. Use UNIFORMAT II to prepare budgets and to establish elemental cost plans before design begins. The project manager uses these to control project cost, time, and quality, and to set design-to-cost targets. See Appendix X2 for an example of a UNIFORMAT II building elemental design cost estimate.4.3.3 Conducting value engineering workshops. Use UNIFORMAT II as a checklist to ensure that alternatives for all elements of significant cost in the building project are analyzed in the creativity phase of the job plan. Also, use the elemental cost data to expedite the development of cost models for building systems.4.3.4 Developing initial project master schedules. Since projects are built element by element, UNIFORMAT II is an appropriate basis for preparing construction schedules at the start of the design process.4.3.5 Performing risk analyses. Simulation is one technique (Practice E1369) for developing probability distributions of building costs when evaluating the economic risk in undertaking a building project. Use individual elements and group elements in UNIFORMAT II for developing probability distributions of elemental costs. From these distributions, build up probability distributions of total project costs to establish acceptable project contingencies or to serve as inputs to an economic analysis. (See Practice E1185 for guidance as to what economic method to use.)4.3.6 Structuring cost manuals and recording construction, operating, and maintenance costs in a database. Having a manual or database in an elemental format helps you perform economic analysis early in the design stage and at reasonable cost.FIG. 1 Possible Framework of the Built Environment4.3.7 Structuring preliminary project descriptions during the conceptual design phase. It facilitates the description of the scope of the project for the client in a clear, concise, and logical sequence; it provides the basis for the preparation of more detailed elemental estimates during the early concept and preliminary design phases, and it enhances communications among designers and other building professionals by providing a clear statement of the designer’s intent. See Appendix X3 for a sample preliminary project description (PPD) based on UNIFORMAT II.4.3.8 Coding and referencing standard details in computer-aided design systems. This allows an architect, for example, to reference an exterior wall assembly according to UNIFORMAT II element designations and build up a database of standard details structured according to the classification.4.4 UNIFORMAT II, as described in this classification, includes sitework normally related to buildings but does not apply to major civil works. It is also unsuitable for process applications or for preparing trade estimates.1.1 This classification establishes a classification of building elements and related sitework. Elements, as defined here, are major components common to most buildings. Elements usually perform a given function, regardless of the design specification, construction method, or materials used. The classification serves as a consistent reference for analysis, evaluation, and monitoring during the feasibility, planning, and design stages of buildings. Using UNIFORMAT II ensures consistency in the economic evaluation of buildings projects over time and from project to project. It also enhances reporting at all stages in construction—from feasibility and planning through the preparation of working documents, construction, maintenance, rehabilitation, and disposal.1.2 This classification applies to buildings and related site work. It excludes specialized process equipment related to a building’s functional use but does include furnishings and equipment.1.3 The classification incorporates three hierarchical levels described as Levels 1, 2, and 3. Appendix X1 presents a more detailed suggested Level 4 classification of sub-elements.1.4 UNIFORMAT II is an elemental format similar to the original UNIFORMAT2 elemental classification. UNIFORMAT II differs from the original UNIFORMAT, however, in that it takes into consideration a broader range of building types and has been updated to categorize building elements as they are in current building practice.1.5 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.1.6 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 Historical Overview—Earthen building systems have been used throughout the world for thousands of years. Adobe construction dates back to the walls of Jericho which were built around 8300 B.C. Many extant earthen structures have been functioning for hundreds of years. However, with the development of newer building materials, earthen building systems have fallen into disfavor in parts of the world where they were once commonly used. At the same time, earthen construction is experiencing a revival in the industrialized world, driven by a number of factors.5.2 Sustainability—As world population continues to rise and people continue to address basic shelter requirements, it becomes increasingly necessary to promote construction techniques with less life cycle impact on the earth. Earthen building systems are one type of technique that may have a favorable life cycle impact.5.3 Building Code Impact—Earthen building systems have historically not been engineered, but as of the late 20th Century it is for the first time in history possible to reliably apply rational structural design methods to earthen construction. A large number of earthen building codes, guidelines, and standards have appeared around the world over the past few decades, based upon a considerable amount of research and field observations regarding the seismic, thermal, and moisture durability performance of earthen structures. Some of those standards are:Australian Earth Building HandbookCalifornia Historical Building CodeChinese Building StandardsEcuadorian Earthen Building StandardsGerman Earthen Building StandardsIndian Earthen Building StandardsInternational Building Code / provisions for adobe constructionNew Mexico Earthen Building Materials CodeNew Zealand Earthen Building StandardsPeruvian Earthen Building StandardsThis guide draws from those documents and the global experience to date in providing guidance on earthen construction to engineers, building officials, and regulatory agencies.5.4 Audience—There are two primary and sometimes overlapping markets for earthen construction and for this guide:5.4.1 Areas with Historical or Indigenous Earthen Building Traditions—In places where earthen architecture is embedded in the culture, or there is little practical or economical access to other building systems, this guide can set a framework for increasing life safety and building durability.5.4.2 Areas with a Nascent or Reviving Interest in Earthen Architecture—In places where earth is sometimes chosen over other options as the primary structural material, this guide provides a framework for codification and engineering design.1.1 This standard provides guidance for earthen building systems, also called earthen construction, and addresses both technical requirements and considerations for sustainable development. Earthen building systems include adobe, rammed earth, cob, cast earth, and other earthen building technologies used as structural and non-structural wall systems.NOTE 1: Other earthen building systems not specifically described in these guidelines, as well as domed, vaulted, and arched earthen structures as are common in many areas, can also make use of these guidelines when consistent with successful local building traditions or engineering judgment.1.1.1 There are many decisions in the design and construction of a building that can contribute to the maintenance of ecosystem components and functions for future generations. One such decision is the selection of products for use in the building. This guide addresses sustainability issues related to the use of earthen wall building systems.1.1.2 The considerations for sustainable development relative to earthen wall building systems are categorized as follows: materials (product feedstock), manufacturing process, operational performance (product installed), and indoor environmental quality (IEQ).1.1.3 The technical requirements for earthen building systems are categorized as follows: design criteria, structural and non-structural systems, and structural and non-structural components.1.2 Provisions of this guide do not apply to materials and products used in architectural cast stone (see Specification C1364).1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.4 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.1.5 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.

This specification covers agencies engaged in system analysis and compliance assurance for manufactured building. The administrative agency may utilize the services and facilities of building-evaluation agencies in carrying out its responsibilities for evaluating manufactured building systems. By providing criteria for evaluating these agencies, this standard's objective is to (1) utilize the voluntary standards system to provide a common base for the various regulatory approaches employed by the authorities having jurisdiction, and (2) make provision for varying degrees of optional technical support for the certification of manufactured building. The system analysis agency is responsible for determining whether a building system, including the design, materials, and fabrication process, is in conformance with applicable requirements. The documents of the system analysis function are: product description document, compliance assurance manual, and installation documents. The general procedures for system analysis are presented in details. The tasks of system analysis project manager, technical staff evaluating building systems, technical staff evaluating compliance assurance manuals, and project manager evaluating building systems are presented in details. The requirements and criteria for compliance assurance agencies are presented. The task of compliance assurance agency project manager, technical staff preparing compliance assurance manuals, compliance assurance supervisor of inspection, and compliance assurance inspector are presented in details.1.1 This specification provides the criteria for the administrative agency that has regulatory authority as granted by the authority having jurisdiction AHJ to evaluate the capabilities and qualifications of building evaluation agencies, that performs system analysis or compliance assurance or both for certification of manufactured building on behalf of an authority having jurisdiction (AHJ) that meet the needs of regulatory programs. Administrative agencies and building evaluation agencies (third-party agencies) are the primary users of the standard.1.2 To establish an appropriate degree of intra- and inter-state credibility regarding building system evaluations made through governmental or private agencies, the authorities having jurisdiction should utilize an oversight and approval process for the building-evaluation agencies that provide the services of system analysis or compliance assurance on behalf of the AHJ that may include: approval by the AHJ for both oversight and or auditing of the regulatory body, or approval by the AHJ and oversight, and or auditing by an independent auditor for the regulatory body, or approval with the AHJ and oversight, and auditing by an independent accreditation agency.1.3 Building-evaluation agencies examined under this specification may include governmental or private agencies or both.1.4 Practice E651 may be used to support the evaluation of building-evaluation agencies. Other criteria such as independence, financial stability, and objectivity may need to be considered.NOTE 1: Practice E651 is intended as a companion standard to Specification E541 and includes questions that should be asked of system analysis and compliance assurance agencies in order for the administrative agency to evaluate their competency.1.5 These criteria set forth the minimum personnel requirements and the technical and organizational procedures required for building-evaluation agencies engaged in evaluating manufactured building.1.6 Criteria are included for building-evaluation agencies evaluating innovative as well as conventional building systems, against applicable requirements.1.7 Building-evaluation agencies involved in testing, quality assurance, and evaluating building components can be evaluated by using Specification E699.1.7.1 Specification E699 is used in conjunction with Specification E541 and Practice E651. This specification defines the minimum requirements for agencies engaged in inspections and testing performance in accordance with ASTM standards for factory-built building components and assemblies. The criteria in this specification are provided for assessing the competence of an agency to properly perform designation testing, quality assurance, and inspection.1.8 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.1.9 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.
