What is ISO 21105‑1 – Performance of buildings about?
ISO 21105‑1 is the first part of the ISO 21105 that discusses building performance.
ISO 21105‑1 describes a building enclosure commissioning process to achieve a well-performing, durable and maintainable building enclosure. ISO 21105‑1 includes procedures, methods and documentation requirements describing the application of the commissioning process to a building enclosure at each phase of a project. These project phases span from predesign through owner occupancy and operation. This process is referred to throughout ISO 21105‑1 as building enclosure commissioning (BECx).
ISO 21105‑1 applies to new building construction and building re-commissioning. ISO 21105‑1 identifies steps necessary to perform a building enclosure risk analysis. The analysis will result in tasks that define the level of BECx, commensurate with the owner’s tolerance for risk associated with building enclosure performance.
The BECx process covered by ISO 21105‑1 is applicable to an individual assembly, a combination of assemblies or a whole enclosure assembly.
ISO 21105‑1 describes requirements for any third-party consultants and/or building enclosure commissioning providers (BECxP) to document their technical qualifications, independence and knowledge of the BECx process, including their education, training, and experience
Who is ISO 21105‑1 – Performance of buildings for?
ISO 21105‑1 on verification and commissioning of thermal performance of building enclosures is useful for:
- Building owners
- Commissioning providers
- Building developers
- Building owner’s representatives
- Construction managers
- Architects
- Contractors/consultants
Why should you use ISO 21105‑1 – Performance of buildings?
The commissioning process is developed on behalf of the owner. The process facilitates the owner’s transfer of their expectations for the building to the design and construction team. The process is founded in collaboration among all parties comprising the commissioning team. The commissioning process is the most successful when the owner takes an active role in the process.
ISO 21105‑1 empowers your (building owners) engagement in commissioning by defining the tasks associated with the process that specifically serve your needs and add value to the project. ISO 21105‑1 provides a performance verification process to achieve a durable building enclosure that performs in accordance with the contract documents and owner’s project requirements.
The process described in ISO 21105‑1 assists you in developing the client’s project requirements, defining system performance and acceptance attributes, design and construction activities and verifying the building enclosure’s performance.
