So grateful to Lew Harriman & Cynthia Harriman for the opportunity to attend Joe Lstiburek & Betsy Pettit ‘s Building Science Symposium.
A lot to say in one post so this one will be about Lew & his wife Cynthia.
They are a most generous, nerdiest power couple (as are Joe & Betsy).
Over the past few days I was immersed in the landscape of Portsmouth, NH & northern MA.
I learned way more about dehumidification & HVAC than I ever have before & it turns out when it is taught with kindness & jokes, it sticks better!
Also learned that Cynthia’s grandfather was a rival influencer of FLW! Those drawings!
