This article explores some of the benefits realized through the speed of construction enabled by specifying insulating concrete forms (ICFs)—a technology that combines reinforced concrete with thermal insulation. The piece profiles diverse projects—a school, a multi-family midrise, a big box, and a hotel—in detailing the cost efficiencies. It also looks at ICF design possibilities, installation techniques, and accessory products.

Masonry materials and wall systems, with their inherent thermal mass characteristics, provide designers with many options to achieve energy-efficient designs. This article illustrates examples of wall configurations that exceed national building code requirements and high-performance standards, taking into account factors like increased R-values for non-mass opaque walls (prescriptive design), continuous insulation, requirements for R-value reductions caused by thermal bridging, mandatory continuous air barriers, and options for building energy design.

Metal Wall Panels on the Roof: How to achieve durability and reliability using sheet metal

Some modern architectural designs use newer materials and metal panel assemblies for roofing applications, many of which are not intended to be used as roofing and, therefore, may not be well-suited for it. One such trend is the use of architectural metal wall panels as roofing to create a visually seamless transition between building walls and roof surfaces such as low-slope setbacks in the façade. This can impose unique challenges for the designer and contractor.

This article describes the air barrier performance requirements for the desired wind load design specifications. The performance level is not determined by the type of air barrier material, but by the installation details. Examples of how these details can impact the performance level for a given air barrier system are provided, with special emphasis on mechanically fastened air barriers.
