Building Envelope Commissioning

Building Envelope Commissioning (Cx), or also known as Exterior Enclosure Commissioning is intended as “a quality-oriented process for achieving, verifying, and documenting that the performance of facilities, systems, and assemblies meets the owner’s defined objectives and criteria" (NIBS Guideline 3-2006).  The Building Envelope Commissioning Process assists in the design and construction phases to increase the overall quality of the building.  The result is verification that the owner’s project requirements (OPR) are accurately recorded, represented, and translated through the design, construction, and operation phases of the project.


Building Envelope Commissioning benefits the Owner, Occupants, Builder and Designer:

  • U.S. Green Building Council LEED Scoring Program - Eligible for Exemplary Performance Point under Energy and Atmosphere - Enhanced Commissioning (EAc3).
  • Increased Energy Efficiency
  • Coordinated design between inter-related building systems to achieve optimum performance of the building’s components.
  • Increased efficiency of Design phase activities through a structured work flow
  • Reduced construction phase delays caused by missing details or coordination issues with defined Pre-Construction conferences and Construction Checklists.
  • Field Inspections to verify correct installation of the exterior enclosure systems and tracking issues to resolution.
  • Field Testing of the building envelope for potential water and air intrusion.
  • Verification of Warranties, Training and Maintenance Manuals.


Building Envelope Commissioning involves several phases: Pre-Design Phase, Design Phase, Construction Phase, Testing and the Occupancy Phase.

Criterium Engineers will collaboratively work together with your team from the project inception to help determine the priorities of the Owner, Designer and Contractor, as well as assist in developing a scope and budget to accomplish the stated goals agreed upon during the Pre-Design Phase

Our experience with Constructability and Peer Review of construction documents, combined with highly certified field staff around the country, make Criterium Engineers a valuable contributor to your Design Phase efforts.

With a 50-plus year history of inspecting buildings, Criterium Engineers has developed unique knowledge of how buildings, systems and assemblies succeed or fail.  This expertise has led us to develop quality assurance services for new construction in addition to our inspection services of existing buildings.  These skills are used to train, document, inspect and conduct testing during the Construction Phase of your project and transition smoothly into the Operations and Occupancy of the building.


The Building Envelope Commissioning responsibility can be handled in many different contractual scenarios.  With the Commissioning process intended to be flexible and project specific, the role, responsibilities, and reporting process of the Building Envelope Commissioning Agent can vary as needed for each project/client.

Criterium Engineers has experience as the Building Commissioning Authority (CxA) responsible for the entire Building Envelope Commissioning process, while on other projects we have functioned as the Building Envelope Commissioning Agent under a different Building Commissioning Authority, or directly to the owner.  In all cases the reporting remains as an independent 3rd party, thus allowing the contract for Building Envelope Commissioning to be held by whomever the Owner deems appropriate.


Building Envelope Commissioning combines varied skills and expertise to assure that the building envelope will perform as designed and expected.  Current and past projects as diverse as an outpatient clinic for the Veterans Administration and a landmark expansion to a major metropolitan airport are part of our corporate resume making Criterium Engineers a premier candidate for your next Building Envelope Commissioning opportunity.
