As with most construction and renovation work, there is no replacement for experience. There is also great value in becoming educated in subjects like the physics of materials and fundamentals of building science.

From a practical point of view, a Building Envelope Specialist is someone who has broad experience in new construction and renovations, both on the ground installing and in the planning and management of projects. This specialist will also have a working knowledge of materials used as control layers and the proper sequencing for maximum effectiveness.

This person will also understand the main principles of building science: how heat, air and moisture behave in a structure and how they should be managed. They will know how to communicate with other experts in building performance, such as Energy Advisors and HVAC technicians, in order to create the optimal conditions for comfort and energy efficiency.

A Building Envelope Specialist may have the following attributes and experience:

• 3 to 5 years experience installing air barriers, insulation, flashing and windows and doors;
• 5+ years experience in construction and renovation;
• Specific manufacturer certifications for installing air barrier, insulation and sealant products;
  
• Understanding of performance targets such as airtightness, optimized R-value and indoor air quality;
• Experience working with other trades and technicians to achieve performance goals.
