Get expert guidance on a wall assembly’s moisture durability and energy efficiency.

The Building Science Advisor (BSA) Tool, is provided by Oakridge National Laboratories. BSA is a no-cost, web-based tool that provides expert guidance on the moisture durability and energy efficiency of new and retrofit wall assembly designs.  Click here to watch a CEU webinar on the benefits of this tool and how to navigate it.

Building Science Advisor (BSA) allows users to compare the performance of different combinations of wall components, providing rapid feedback and guidance on the design of a wall assembly based on expert knowledge and thousands of pre-simulated hygrothermal models.

Assess a wall assembly

Get estimates of the thermal efficiency, mold resistance, and moisture durability of different wall assemblies within different climate zones in the United States. Additionally, gain insights into what type of retrofit and what retrofit components will be most beneficial in any chosen climate zone.
