Air Barrier Continuity Failures: Where Buildings Hemorrhage Energy and Why

Understanding Air Leakage Path Identification

In the building envelope consulting industry, understanding air leakage path identification is essential for preventing costly failures and protecting building investments. ACE Building Envelope Design brings decades of forensic investigation experience to every project across our seven-state Western U.S. service territory — California, Arizona, Nevada, Idaho, Oregon, Utah, and Washington. Our work spans affordable housing, market-rate multifamily, commercial, institutional, and custom residential developments.

The challenge with air barrier continuity is that problems are often invisible until significant damage has occurred. Water can travel through concealed pathways within building assemblies for months before becoming visible, and by the time symptoms appear, the underlying damage is typically far more extensive than what’s visible on the surface. Early identification and expert assessment are critical to minimizing remediation scope and cost.

According to industry research from DOE, building envelope failures represent one of the largest categories of construction-related losses in the United States. The Western U.S. faces unique challenges including atmospheric rivers in coastal California, extreme heat in Arizona and Nevada, and freeze-thaw cycling in Idaho and Utah — all of which stress building envelope systems in ways that require climate-specific expertise.

Critical Factors in Energy Loss Through Envelope Gaps

ACE’s forensic investigation experience across thousands of projects has identified consistent patterns in air barrier continuity situations. Understanding these patterns allows our Air & Thermal Barriers team to diagnose problems accurately and design solutions that address root causes rather than symptoms.

Design-Phase Considerations

The most effective time to prevent air barrier continuity failures is during the design phase, when corrections cost dollars instead of thousands. ACE’s Air Leakage Problems identifies vulnerabilities in design documents before they become field problems. This includes reviewing material selections, detail configurations, integration sequences, and compatibility between adjacent building systems.

Construction-Phase Verification

Even well-designed details can be compromised during construction if installation doesn’t match design intent. ACE’s ASTM E783 Air Testing provides observation at critical milestones to verify that field conditions match design requirements. Our scope-appropriate turnaround report turnaround ensures that identified issues are documented and correctable before subsequent work conceals them.

Climate-Specific Considerations

The Western U.S. presents unique challenges for air barrier continuity. Coastal California’s atmospheric rivers produce sustained, high-intensity rainfall. Arizona’s extreme heat accelerates material degradation. Idaho’s freeze-thaw cycles stress connections and sealants. Each climate zone requires specific design responses that generic details from manufacturer literature may not address. The ASHRAE provides standards that ACE applies to every project’s specific climate exposure.

ACE’s Approach to Continuous Air Barrier Design

When air barrier continuity issues are identified in existing buildings, ACE’s Air Barrier Solutions follows a systematic forensic methodology that identifies the true root cause of the failure — not just the visible symptom.

Our diagnostic process combines non-destructive assessment methods (infrared thermography, calibrated moisture meters, visual assessment) with targeted testing per published ASTM E783 standards to build a complete picture of what’s happening within the building assembly. This evidence-based approach eliminates guesswork and produces findings that are both technically accurate and legally defensible.

ACE’s FGIA/AAMA accreditation ensures that all testing results meet the highest recognized industry standards for accuracy, methodology, and documentation. This accreditation is particularly important for projects where testing results may be used in warranty claims, construction defect litigation, or code compliance verification.

Preventing Astm E783 Air Testing in New Construction

For developers, architects, and contractors working on new construction projects, prevention is orders of magnitude less expensive than remediation. ACE’s integrated service model — spanning envelope design, construction administration, accredited testing, and forensic investigation — means that a single team manages building envelope quality from design through occupancy.

This continuity eliminates the coordination gaps that occur when different firms handle design review, construction observation, and testing. The design team that reviewed the details is the same team observing installation and testing performance — ensuring that design intent is maintained through every phase of construction.

ACE’s leadership — CEO Conor Meyers, President John Harris, Director Jedidiah Brandman, and Kevin Moultrie — are directly accessible to every client through individual online booking links. This means you speak with senior decision-makers from the first consultation through project completion, not junior staff who must escalate questions through bureaucratic approval chains.
