The National Institute of Building Sciences (NIBS) describes Building Enclosure Commissioning (BECx) as a process which validates that the performance of materials, components, assemblies, systems, and design achieve the objectives and requirements as established by the Owner. 

BECx is woven into the project timeline with the purpose of reducing the cost of delivering construction projects and increasing value to owners, occupants, and users.

The following standard practices and guidelines provide detailed information on BECx and the Commissioning process.  Consistently following these published guidelines can ensure the commissioned building enclosure has been carefully planned and constructed in a way that meets the needs and expectations of the Owner.


    Pre-Design Services

    • The focus is on defining project expectations
    • Develop/assist in Owner’s Project Requirements (OPR) Document

    Occupancy and Operations Services

    • The focus switches to Owner training and maintenance
    • Review of close-out report
    • Training of facility maintenance personnel
    • Pre-expiration of warranty review
    • Review of Current Facility Requirements (CFR)
    • Re-commissioning and on-going commissioning

    Define Project Expectations

    Pre-Design is a preparatory phase of the project delivery process in which the Owner’s Project Requirements (OPR) are established and general information about the overall project is gathered

    Quality Assurance

    The Design Phase is comprised of tasks that verify the Owner’s Project Requirements (OPR) are comprehensively outlined, detailed and specified in the Contract Documents

    Quality Control and Verification

    During the Construction Phase, the project is validated through observations and testing, to verify it meets the criteria established during the Design Phases   

    Owner Training and Maintenance

    During the Occupancy and Operations Phase, the on-going operation, maintenance, and modification of the facility systems and assemblies, and their associated documentation, are verified against the OPR.
