Today building owners are faced with increasingly complex
building enclosure (envelope) design, new construction materials, shrinking schedules,
and code requirements to deliver energy-efficient buildings. The building enclosure
must be constructed to meet the design intent for expected service life and
energy use, and to prevent adverse outcomes that may arise from deficient
workmanship during construction.
Building enclosure commissioning (BECx), from the design to completed construction, fulfills this imperative. The presenters will identify and discuss the procedures that should be included in the building enclosure commissioning process—starting with the OPR, design, submittal reviews, project start-up, and orientation meetings, followed by preparing functional performance testing plans, conducting mock-up testing, on-site quality control, and quality assurance programs. The presentation concludes with how to test airtightness and insulation barriers of the finished building.
Over the past several years CSA and ASTM have published standards and guides outlining procedures for a comprehensive building enclosure commissioning process, and the presenters will discuss these currently available resources.
