Building Envelope vs. Building Envelope Commissioning

How can we assist you in achieving your goals?

What is the difference between building envelope (BE) and building envelope commissioning (BECx)?

A building envelope is the physical separator between the conditioned and unconditioned environment of a building including the resistance to air, water, heat, light, and noise transfer.

We specialize in Building Envelope Commissioning, a strict quality-focused process wherein the energy performance of a facility, system, or assembly is evaluated and verified against defined objectives and criteria. Commissioning starts in the earliest phases of a project and continues until after the project is complete.
