Pro Tour: Affordable Passive Multifamily in Maine

Brewer Passive House

Event Date:

Brewer, ME

On a sunny spring Friday, approximately 40 members of the NESEA community came together to tour the Village Centre Apartments in Brewer, ME. While the Village Centre housing project will be one of the largest passive housing projects in the United States when completed, perhaps its most impressive feature is its budget. Village Centre was able to meet the Maine State Housing Authority's aggressive affordable housing cost cap. The tour featured a walk-through of some of the tips and tricks that made this possible, as well as a review of some large scale multifamily air-sealing measures. The host of this Pro Tour was NESEA business member Thornton Tomasetti.

Member registration: $25 | Non-member registration: $35
