Principal Building Scientist

Figures out how heat, air, and water move through buildings and why some rot, leak, or grow mold.

A day in the life

You cut open a wall in a five-year-old condo to find out why it is rotting, take moisture readings, and trace the problem to a missing flashing. Then you testify as an expert witness.
