A net zero home is a house that produces as much energy as it consumes each year. Because Net Zero Homes are tied to the grid, they can draw electricity when their renewable source can’t meet demand and sell it back to the grid when...

The snow melted and the timber frame crew jumped to work. The entire frame was hand cut off site by Hardwick Post and Beam. The crew worked quickly and raised the frame in less than a week. Here the first of four bents, or sections...

Our weatherization crew does a lot of work on roofs. Whether it is installing a roof flapper for a bath vent or creating a ridge vent to get moisture out of the attic, crew members find themselves climbing and working on steep roofs that can...

What do you feel you are born to do? Is it to Run? In his popular bestseller, Born to Run, Christopher McDougall marshals evidence from anthropological studies, from a hidden tribe in Mexico and from an elite group of superathletes to argue that as a species...

We are in the design phase of constructing our first Zero Net Energy capable home. In our last new home construction project our goals were more modest: we wanted to meet the unofficial standard for a super-insulated home as defined by the Building Science Corporation; and we...

It is made from 85% post consumer recycled materials (essentially shredded newspapers and pulp fiction). It has compelling r-values and it is completely inflammable (the 15% non-recycled content is a borate mix serves as a fire retardant and moldicide).

I am a member of Bottom Lines, a peer review network of builders and architects sponsored by NESEA. The fundamental mission of Bottom Lines is to support companies in their efforts to attend to a triple bottom line: profits, people and planet. The group has...
