Habitat for Humanity - Freeport, Maine
Nicknamed “Green Bean,” this new energy efficient Habitat for Humanity home boasts an R66 roof and R25 wall system.

A few weeks ago ReVision staffers Josh Baston and Geoff Sparrow helped with our second Habitat for Humanity project.

They installed and vented a 95% efficient condensing gas boiler for a new home that will house a single mother and child. These boilers achieve this high rate of efficiency by condensing exhaust gases as water vapor and recovering additional heat from them.

The home is nicknamed “Green Bean” by Habitat for Humanity, as it represents the 5th home in their green building efforts and was originally owned by LL Bean.

LL Bean found they needed to expand their parking lot to where the house was located, and rather than demolishing it they donated the house along with some funds to Habitat for Humanity.

Habitat took the house to its new location, and started greening the 1930s-era house in earnest.

Using a product called Nailbase, Habitat achieved an amazing R66 rating in the roof, and built up the walls to R25. The house is now so tight that they needed to install an HRV! The gas boiler that ReVision installed will be used for heating and domestic hot water.

ReVision’s first Habitat for Humanity project was a solar hot water system for a LEED home, installed in Portland. See the blog archives for a write-up or see more project photos.
