Proposer Additional Info
My career in the building trades started in high school in my hometown of Bristol, VT. For twenty-odd years I wore a belt as a frame-to-finish carpenter (with a couple trips around the world and a college degree in Sustainable Agriculture thrown in there for good measure). I began swinging a hammer for Silver Maple Construction in 2012 and five years later I began installing AeroBarrier and also received BPI certifications as a Building Analyst and Envelope Professional. Hundreds and hundreds of blower door tests later I started my own company, Green Mountain Enclosure Consulting llc where I keep busy as a building envelope consultant and certified Building Enclosure Commissioning (BECx) provider, offering services including: design review; specification writing assistance; residential and commercial whole-building airtightness testing; qualitative thermal imaging; on-site progress testing and field verifications; envelope failure forensics; existing building envelope assessments; and building science teaching and presentations. I’m a voting member of ASTM Committee E06 and am very happy to say that I also serve on the Board of Directors for the Vermont Green Building Network. I play the banjo sometimes, and hunt whenever I can.

Full Description
Whole Building Airtightness Testing (AKA blower door testing) is now commonplace on both residential and commercial construction projects across New England. It is often required by building codes, and the associated metrics and acronyms will likely come up in conversation throughout every phase of a project, from pre-design to substantial completion. Knowing and understanding the relevant methods, metrics, and meanings that are common to whole-building airtightness testing will benefit all members of a building project.
