Flooding roofs is not best practice due to the possibility of damage to the structure or roof elements. Roofs also can be tested by spraying or flooding roofs and then investigating the roof system for leaks by thermal or conductance measurements or observations. This is most effective when applied to single transitional elements such as window/wall or door/wall transitions or wall-to-roof or wall-to-footing transitions. Water intrusion testing is done by spraying water against windows, doors, and wall assemblies while the building is under negative pressure to find any water leaks in those assemblies. The technical commissioning process uses the expert commissioning provider process, instead of the contractor quality process, to achieve these results, and uses both testing of the envelope components and installation inspections.

To overcome the lack of effective commissioning of these envelope assemblies, organizations like the National Environmental Balancing Bureau (NEBB) have begun to use the technical commissioning process on building envelopes with improved success. The building envelope consists of an exterior cladding, water channel layer, air barrier, vapor barrier, and an insulation barrier, each of which must be installed correctly without holes or voids in any of the layers to provide the intended performance (see Figure 1). The traditional contractorвЂ™s quality process has not been effectively used on building envelopes due to the fact that the assemblies are field built by multiple contractors at various times during the construction process. Due to the increased interest in high-performance buildings, more attention is being paid to how envelope assemblies affect interior comfort and energy performance.

(BESI) is to provide the highest quality of training and certification programs resources as well as overall knowledge in successfully constructing, maintaining, and restoring building envelope construction investigation and analysis of new products and materials which will further develop and enhance the building envelope construction and continuing the development and formal certification for construction industry practitioners. The course is designed to benefit architects, engineers, inspectors, project managers and other construction industry professionals desiring more knowledge and to develop superior skills.ДЄbout BESI: The mission of Building Envelope Science Institute, Inc.

The Building Envelope Inspector (BEC-2) course, which includes BET-1, is designed to provide qualified industry professionals with enhanced knowledge of the building envelope, inspection methods and techniques, restoration techniques, and much more. The Building Envelope Trained (BET-1) course is designed for any industry professionals such as property managers, manufacturers, realtors, and distributors who desire a greater understanding of how the building envelope components come together to form a single cohesive unit. These are some of the most comprehensive courses offered for building envelope training and certification.
