Welcome to Barrier Sciences Group
A new approach to building envelope solutions

Barrier Sciences Group is a building envelope consulting firm that specializes in deep energy retrofit for residential, industrial, commercial and institutional buildings.  The professionals at BSG have over three decades of experience and expertise working with building envelopes. 

We offer our clients an accomplished team of skilled and seasoned specialists:  building science technologists, thermographers, field investigators, energy auditors, and engineers. 

Traditionally, energy retrofits are based on a “shotgun” model, where solutions are executed en masse, and at the same time.  But at Barrier Sciences Group we have a much better approach - we employ an “incremental” model, which allows us to properly assess the value added by a specific retrofit solution.

Implementing retrofits incrementally allows BSG to conduct ongoing, real-world evaluation of the effect of each retrofit on building performance.
