The building envelope is the unsung hero of construction—and we’re not just saying that because we’re biased and love our field. It provides protection against the elements, plays a critical role in energy efficiency, and maintains the overall integrity of the building. It’s also usually one of the most prominent features of a building’s architecture.
There are several misconceptions related to the building envelope, however, which can lead to unnecessary headaches and costs. In this post, we’re aiming to debunk some of the more common myths we hear about building envelopes.
MYTH #1: The building envelope is the same as the facade.
“Facade” usually refers to a building’s exterior walls. While the walls certainly play crucial roles, they’re just part of a bigger picture.
The building envelope includes all components that separate what is “inside” from what is “outside”. We often say that the building envelope includes “all six sides” of the building, imagining a simplified building as a cube shape.
The building envelope includes the roof, windows, doors, foundation walls, insulation, and even the sealants and caulking that fill gaps between other components. Ignoring the interconnectedness of these elements can lead to a range of issues including moisture problems, occupant discomfort, and structural damage.
MYTH #2: New buildings don’t have building envelope issues.
Newly constructed buildings often experience building envelope problems. In fact, they’re quite common.
One dynamic that often plays out in new construction is a building project development team will undervalue the risks posed by typical building envelope design and construction practices. When strong incentives to keep cost down combine with idealized marketing messages from product and material manufacturers, the result is often a project viewed through rose-colored glasses.
It is all too easy for stakeholders to optimistically hope that things will work out, rather than realistically plan for inevitable imperfection.
MYTH #3: Once built, building envelopes require minimal attention.
It’s a common misconception that once a building is constructed, the work on its building envelope is done. Especially with roofing, it is often “out of sight, out of mind”—but even visible components like exterior walls typically go unnoticed until there is a problem.
Building envelopes are not a set-and-forget aspect of construction. Regular inspections and maintenance are crucial to identify and address potential issues before they escalate. Ignoring routine upkeep can lead to compounding issues such as water infiltration or structural damage.
Proactive care improves the longevity and functionality of the building envelope, while reducing the overall cost of ownership. See our post on The Importance of Maintenance Planning for more.
MYTH #4: Building envelope repairs are always invasive and costly.
Building envelope repairs can take various forms, and the right approach depends on the specific needs of the building and its stakeholders. The key to choosing the right path lies in a thorough assessment by an unbiased expert who can recommend practical, project-specific solutions that address the root cause of the problem, thereby enhancing the building’s performance and longevity in a cost-effective manner.
Costly and invasive building envelope repairs are often the result of a problem that has been allowed to fester. Most of the time, catching a problem early opens up a wider range of options and allows stakeholders to develop a plan to reliably address the issue on a timeline and budget that works for them.
MYTH #5: Building envelope consulting is a commodity service.
We are often asked to submit a “bid” for project opportunities; we always politely decline. We prefer to form a collaborative partnership with our clients based on mutual trust and shared goals. One of these goals should be to generate a significant return on the client’s investment in our expertise.
Building envelope consultants offer a range of services, and their expertise can vary. Some may specialize in specific types of buildings, climates, or construction materials. Consultants have different education, training, and certifications. The client experience working with one firm is different than when working with another.
All of these factors, and more, mean that building envelope consulting is a specialty service that is best engaged based on a nuanced review of one’s own specific needs. We would be pleased to talk with you to see if we might be a good fit to help you achieve your project goals.
