Mass Audubon Drumlin Farm Environmental Learning Center passed its final blower door test with flying colors! The amount of air leaking through the building envelope was less than half that allowed by specification. A tight building is a key component of a net zero building. #PathToNetZero 

The siding on the Mass Audubon Drumlin Farm Environmental Learning Center is held off from the moisture resistant air barrier on the sheathing to create a drainage plane and vented air space that allow the walls to breathe and contribute to our #PathToNetZero.

Happy anniversary to all those celebrating their work anniversaries in April! Joe Cahalane – 25 years Jason Grinacoff – 13 years Ken Bumpus  – 12 years Christine Mercier – 12 years Ryan Aghoian – 7 years Ted Stachnick  – 6 years Kevin McGinty  – 4 years Nate Cote – 3 years

At Mass Audubon Drumlin Farm Environmental Learning Center we insulated between the studs and rafters with dense pack cellulose (recycled newsprint) because its Global Warming Potential is more than 95% lower than spray foam. #PathToNetZero
