Evidence-Based Diagnostics

If you're dealing with a building envelope performance issue — water intrusion, air leakage, thermal deficiency, or a construction defect dispute — the quality of the outcome depends entirely on the quality of the diagnosis. Building envelope testing transforms speculation into evidence. It replaces assumptions about where water is entering with measured data documenting the exact breach location.

ACE Building Envelope Design is an FGIA/AAMA-accredited testing agency — meaning our testing procedures, equipment calibration, and personnel qualifications have been independently audited and verified. This accreditation ensures that test results are reproducible, defensible in legal proceedings, and accepted by manufacturers, owners, construction attorneys, and courts. Standard testing reports are delivered within one week of site visits.

FGIA/AAMA-accredited building envelope water penetration testing in progress

ASTM E1105 Water Penetration Testing

ASTM E1105 water penetration testing is the standard diagnostic procedure for determining whether installed fenestration and wall assemblies resist water penetration under specified pressure conditions. ACE performs this test applying calibrated water spray to the test area while maintaining a specified air pressure differential across the assembly. This simulates wind-driven rain conditions and reveals whether the as-installed system meets its performance specifications.

ASTM E1105 testing is essential for new construction quality assurance, warranty verification, and forensic investigation of active leaks.

Diagnostic Test Application Frequency by Purpose

ASTM E783 Air Leakage and Infrared Diagnostics

ASTM E783 air leakage testing quantifies the rate of air infiltration through fenestration and wall assemblies under specified pressure conditions. This test produces measurable data that can be compared against ASHRAE standards and contract specifications. For buildings experiencing rising energy costs, ASTM E783 testing provides the evidence needed to determine whether the envelope is meeting performance requirements.

Infrared thermography complements air leakage testing by providing visual documentation of thermal anomalies across the building envelope. ACE deploys both handheld and drone-mounted infrared cameras to survey entire building facades rapidly.

Flood Testing and Electronic Leak Detection

Flood testing evaluates waterproofing membrane integrity on horizontal surfaces — podium decks, plaza systems, green roofs, and below-grade slabs — by maintaining a controlled depth of water over the membrane for a specified duration. This test reveals breaches that may not be apparent during visual inspection.

Electronic leak detection (ELD) uses electrical impedance testing to locate breaches in waterproofing and roofing membranes with pinpoint accuracy. Unlike flood testing, ELD can be performed on membranes that have already been covered with overburden.

AAMA Fenestration Performance Testing

AAMA fenestration performance testing evaluates the installed performance of windows, curtain walls, storefronts, and skylights against standards established by AAMA. ACE performs AAMA 501, 502, and 503 test procedures that assess water penetration resistance, air infiltration rates, and structural wind load performance.

Fenestration testing is particularly important for commercial buildings and high-rise towers where curtain wall systems are the primary weather barrier. ACE's FGIA/AAMA accreditation means that fenestration test results carry the authority of an independently verified testing agency.

Frequently Asked Questions

What diagnostic tests does ACE perform?

ACE performs ASTM E1105 water testing, ASTM E783 air testing, infrared thermography, flood testing, electronic leak detection, and AAMA fenestration testing.

What does FGIA/AAMA accreditation mean for testing?

Accreditation means ACE's procedures are independently verified, and results are reproducible, defensible in legal proceedings, and accepted by manufacturers and courts.

How quickly are test reports delivered?

Standard reports within one week of site visits. Same-day consultation for urgent issues. Field teams deploy from Concord, CA and Nampa, ID.

When should envelope testing be performed?

During construction for QA, at substantial completion for warranty documentation, during forensic investigations, and during condition assessments of existing buildings.

Can ACE test occupied buildings?

Yes. Most procedures work on occupied buildings with minimal disruption. We coordinate with building management to protect interior finishes and schedule testing appropriately.
