About Us

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.

Our incremental approach is a unique, step-by-step model, whereby the most beneficial, cost-effective retrofit is implemented first - then, as necessary, followed by the next most beneficial, cost-effective retrofit, and so on.  Based on each retrofit outcome, and a consequent assessment, Barrier Sciences Group can determine if the implemented retrofit successfully meets expected “performance goals” or if additional retrofits are required.

Barrier Sciences Group believes in a common-sense approach to problem solving, one that is supported by sound building science, and further complimented by best construction practices.  In short, we are committed to being Canada's most trusted name when it comes to deep energy retrofit programs.  In our day-to-day practice, the focus at BSG is on improving and optimizing the energy performance profile of the building envelope.

On the job, the team at Barrier Sciences Group recommends retrofits designed to resolve a wide range of challenges.  And the results are substantial and measurable:  reduced operating costs through improved energy efficiency; diminished potential for building decay over the long run; improved integrity of the building envelope; extended lifespan for building components; and enriched health, safety and well-being for the building’s occupants.

For building envelope issues and concerns of any kind, nothing quite compares with the Barrier Sciences Group approach.  We provide our clients with in-depth investigation and examination – we follow with comprehensive assessment and analysis - and we continue with viable project recommendations.  The bottom line for our clients:  our “incremental” approach to deep energy building envelope retrofit delivers quantifiable results.
