Pioneer Valley Habitat for Humanity: "Not only is this build our first Easthampton home, but it is also our first ever Women Build home and our first zero net energy potential house! That's a lot of firsts!" This is a fitting project to be the MJ Adams Legacy Build, in honor of the chapter's first director.
This project aimed to raise the bar in a lot of areas where PV Habitat has been gaining ground in the past decade. Energy efficiency and waste reduction were getting more and more successful, and we thought a bold goal would be a great way to stretch capabilities.
The cottage-style two-story home is the west side of a zero-lot-line project, where each family independently owns their land and home even though they share a wall, which helps reduce envelope exposure. A 4-bedroom, 2-bath home, it will be occupied by a single mother with three children. Due to a generous donation from PV Squared of a huge array--over 7kW--the home has the potential to reach net zero depending on the family's use patterns.
