ASTM E779 and E1827 Testing Built for Commercial Projects
Commercial blower-door testing at the whole-building level requires more than just showing up with a fan. We execute per ASTM E779, the primary standard for air leakage testing ASTM E779, reporting results as ACH75 or as an air leakage rate normalized to building envelope area. When project conditions or engineer specifications call for the orifice method, we shift to ASTM E1827 without disrupting your schedule.
Air Barrier Testing for Large and Complex Structures
For large multi-zone buildings where single-setup pressurization isn’t feasible, we apply a sequential sampling approach. Tenant suites, floor zones, or building sections are tested individually, and results are aggregated per your project specifications. This makes whole building air barrier testing practical at scale without sacrificing accuracy or documentation quality. Building codes and LEED requirements are fully supported through this process.
Building Envelope Air Leakage Testing
We’ve completed ASTM E779 blower-door testing at JPMC bank branches across multiple states in the Southeast. Our knowledge of equipment, protocols, and standards also equips us to perform building-envelope air-leakage testing for medical office buildings, government facilities, schools, and mixed-use commercial projects. Every setup prioritizes first-time accuracy so your project timeline stays intact.
Reporting That Supports Owner and Code Review
Every test we run produces clean documentation. Results are formatted to match what your Cx package, AHJ submission, or owner report requires. ACH75 values, normalized leakage rates, and supporting data are clearly presented. Indoor air quality outcomes and test measures are documented so your closeout package is ready without rework.

About Us
Air Tight Solutions grew from hands-on experience in residential construction. While supporting new home builds, we saw a recurring challenge: navigating complex and constantly shifting energy code compliance requirements was slowing builders and contractors down.
We understood that frustration, and we saw an opportunity to simplify the process. With precision as our foundation and a commitment to excellence, we transitioned our expertise into energy efficiency testing and compliance services with a focus on new construction.
Our work extends into affordable housing as well, where we take pride in helping deliver energy-efficient homes for communities that need them. We believe energy efficiency should be accessible to everyone, and we support builders in making that a reality.
Today, Air Tight Solutions is a trusted compliance partner in the construction industry, backing quality, accountability, and sustainability on every project we take on.
