Habitat for Humanity’s vision is simple: A world where everyone has a decent place to live. It’s achieving it that’s the complex part. The team at the Central Vermont Habitat for Humanity (CVHFH) is working hard towards that goal, and an even loftier one – building one of the highest performing Habitat for Humanity homes to date, in Randolph, VT.
Energy Efficiency: an Essential Need
Building to higher energy-efficient standards is an important consideration for any building project. But the impact on personal health and well-being can be even more significant when making ends meet is a struggle.
“The fluctuating price of energy goes beyond what our families can afford”, says Bruce Landry, Affiliate Building Chair, Volunteer and Weatherization Technician, CVHFH. “The families we partner with start out with very tight budgets and every dollar counts. An energy-efficient home gives stability in heating costs and utility payments.”

Not Their First High Performance Rodeo
The home build in Randolph was designed by architect Neil Husher, of Vermont Architects Collaborative. Neil brought three original designs to the table for consideration, which he modified to suit this specific plot of land, and fine-tuned the energy-efficient features for maximum impact.
Although the CVHFH chapter had completed a passive home build in the past, it wasn’t an option for the Randolph home. For instance, there wasn’t enough southern exposure to provide sufficient solar gain. Differences in the wall construction also make this design a bit simpler – building to passive is more detailed, and takes more time. It wasn’t that the volunteer building crew couldn’t handle the technical details and complexity of a passive house, it just wasn’t the right fit for this project.
The High Performance Building Components
The two-story house features 2′ x 8′ wall construction, and an impressive list of high performance building materials including: Rockwool Safe ‘n Sound batt insulation, Partel VeraPlus smart membrane, Advantech sheathing, 2.0″ Dow Blue Board Styrofoam XPS insulation, Typar WRB, ThermalBuck high performance window bucks, Pella 350 Series windows, Stego Wrap Vapor Barrier, and an Amvic ICF Foundation.
2.5″ ThermalBuck was selected to extend the mounting point for the windows and doors, insulate the rough openings, and prevent moisture at the rough openings – traditionally a difficult detail of any building envelope. ThermalBuck helps simplify the challenge of mounting the windows with the exterior insulation, and integrating the WRB.
“ThermalBuck makes it easier to do the high performance seals.”
– Anne Walker, Project Manager, Central VT Habitat for Humanity
Employees of BRINC Building Products, Inc., manufacturer of ThermalBuck, will be volunteering to help the CVHFH chapter with their ThermalBuck installation in September, 2018. Keep informed on the next steps of this high performance home by following ThermalBuck on social media:
Energy Efficiency in Vermont: More Accessible than Ever
One of the reasons this build was possible? Because it was in Vermont. Efficiency Vermont, founded in 2000 as the nation’s first energy-efficient utility, provides Vermonters with technical and financial support to improve the energy efficiency of their homes, businesses, and communities.
For Central Vermont Habitat for Humanity, this meant not only a significant refund for achieving an established list of standards, but also personalized help in the support of a consultant, Jennifer Severidt. Jennifer was assigned to the project, and provided not just a few answers, but guidance throughout the entire project, answering specific questions like “What specific heat pump would work best?”
“We wouldn’t have been able to attempt this without Efficiency Vermont.”

Habitat for Humanity
Habitat’s mission Is based on the premise that affordable housing plays an integral role in building abundant, strong, and stable communities. Habitat for Humanity is one of the most recognizable efforts to support sustainable housing not only in the U.S, but internationally.

Habitat for Humanity is not a giveaway program. They offer partner families a no-interest mortgage for their home. In addition to a down payment and monthly mortgage payments, the homeowners invest hundreds of hours of their own labor (sweat equity) into building their new home. Families selected are those who need simple, decent housing, but who are unable to get a loan through any conventional means. Read more about how a family can apply and be selected here.
