#Definition building envelope code

In a metal building, the building envelope is comprised of several elements that differ from the conventional construction materials previously mentioned.

This is much more involved than the IECC codes and ASHRAE 90.1 Standard. ASHRAE, for example, has the 189.1 High-Performance Green Buildings. There are also above-code programs that designers can use for more reduced energy overall. However, some states have code-specific requirements that may not allow this. Building designers can choose either option in most cases.

The International Energy Conservation Code (IECC) is another 3-year cycle of the same basic parts: thermal, lighting, and mechanicals. ASHRAE 90.1 covers the thermal envelope, lighting systems, and mechanical systems. Each cycle has changes that need to be addressed. The building envelope design has evolved over the years based on the code cycles. Building envelope has many construction types for both commercial and residential applications. It’s crucial that all these materials are compatible and installed in a manner that ensures the building envelope performs as designed. The materials in the building envelope join the foundation, wall, and roof assemblies, and any glazing (windows), doors, and any other component installed within these assemblies. With the addition of an insulating layer, the masonry wall “assembly” becomes the entire thermal envelope. As an example, a conventional building framed from unit masonry with veneers of stucco or exterior insulation and finish system (EIFS) provides physical structural support and air barrier functions within the masonry itself. It also improves thermal performance and can serve a structural function. It is a combination of materials serving several functions, including serving as weather barrier, air barrier, sound barrier, and a natural light and wind barrier. The envelope, however, does more than separate spaces.

His position with Therm-All pulls from a wide range of experience: project management, design build, pre-engineered building sales, thermal envelope design, energy code compliance, and value engineering. Olver started in the pre-engineered building industry working as a project manager for a Design build/Butler builder and has served as a District Sales Manager with Nucor and NCI. Tom Olver is a District Sales Manager for Therm-All (and has 27 years of construction experience from the general construction and pre-engineered realms. Beals has contributed to many articles and reference guides, and authors bi-monthly commercial energy codes blog called “The Code Man.” He can be reached at Tom Olver

Beals also belongs to the International Code Council (ICC) and is often invited to share his extensive energy code knowledge through presentations at industry conferences. Bill Beals, District Manager of Therm-All Insulation (is a 28-year veteran of the metal building industry and a contributing member of several committees, including the Metal Building Manufacturers Association (MBMA) Energy Committee and NIA’s Metal Building Insulation Laminators Committee.
