What is a building envelope?

Building Envelope Illustration: An Open envelope that looks like a house with the outside elements around it

A building envelope is all the external systems that keep out the elements (air, water, heat, light, weather, and noise) and keep in energy.

The primary exterior systems are roofing, waterproofing (below-grade), and exterior walls. An excellent design addresses these areas to ensure the structure operates as designed, meets code, and is energy efficient.

Where do problems usually occur?

Think of the different components of a building’s exterior as puzzle pieces. In our experience, most problems happen when the puzzle pieces don’t fit together correctly. In other words, most issues occur where the roof, exterior walls, and below-grade waterproofing intersect.

An inspection or assessment of building envelope function looks at the materials and designs of external systems and their relationships with other exterior systems and the activities within these buildings to identify and resolve issues. Applying building science to analyze the enclosure includes looking at:

  • vapor barriers,
  • air barriers,
  • air quality,
  • heating & cooling,
  • climate control, 
  • and much more.

Building envelope consultants focus on the completed puzzle and how well the pieces fit together to keep the elements out versus a contractor responsible for implementing just one part. The ultimate goal is to create a safe, healthy, and comfortable environment!

What is the value of a building envelope consultant?

A building envelope consultant's value lies in mastering the building science, systems, and materials associated with a building's exterior shell or enclosure.

We provide independent, expert, and impartial services because we're not contractors. We don't sell materials or services based on sales or commissions, nor are we confined to specific product lines due to contracts, deals, or commissions. This independence allows us to focus on our client's needs fully. 

Furthermore, we excel in conflict resolution, particularly when building envelope problems that often occur when transitioning from one material or system to another. These transitions typically involve 3-5 different envelope systems, each backed by separate contractors and warranty interests, leading to potential complexities and blame games. However, we strive to navigate these intricate situations, saving our clients from unnecessary stress and enabling them to concentrate on their core activities.

What types of buildings do you work on?

We work on all types and ages of buildings, including schools, universities, churches, government, commercial, industrial, and other commercial facilities.

We do not work on residential properties.
