Proving and Restoring Building Envelope Performance
BEPG helps owners, architects, engineers, and contractors verify performance, solve problems, and protect building envelope integrity through impartial, data-driven testing and assessments.
From design validation to problem diagnostics, BEPG delivers independent building envelope testing and consulting that proves performance before problems occur — and restores it when they do.
Prove Performance Before Problems Occur
BEPG provides design and construction administration, commissioning, and functional performance testing that verify building envelope systems meet project requirements before occupancy. Using our custom dynamic testing equipment, we confirm real-world performance so every enclosure performs as intended from the start.
Find and Resolve Problems Accurately and Safely
BEPG pinpoints and resolves building envelope problems through diagnostic testing, inspection, and assessment — enhanced by drone technology and 3D laser scanning. We deliver clear, actionable data that leads to lasting solutions.
What Real-World Testing Reveals
Dynamic testing exposes how buildings actually perform under wind and water pressures — not just how they’re designed to. The results provide data to improve design details, verify installation quality, and guide durable repairs. BEPG turns that data into confident decisions for owners, architects, engineers, and contractors.
Why Every Building Needs a Building Envelope Consultant
Wind, water, and time will test every building. The question isn’t if — it’s when. BEPG provides the real-world proof that design intent holds up under actual conditions. Our impartial testing and diagnostics ensure your building performs as expected, before problems occur or after they appear.
