Bensonwood Passive House

Bensonwood’s scalable and PHlexible panelized building enclosure systems are suited for passive house performance. Passive House certification is based on a metric rather than a specific design solution and accounts for factors such as climate zone, orientation, square footage, and size and types of windows. This means that a single passive house solution will not work for all projects. Bensonwood’s customizable PHlex system can be applied to many projects to achieve Passive House levels of performance or certification.

Durability | Air Quality | Energy Efficiency

Our Passive House Components


High-Performance Enclosure Systems

  • air


    Our choice of building materials such as tapes, gaskets, and lumber all contribute to lower air tightness rates which improve the air quality and energy efficiency of the home.

  • Water by Adnen Kadri from the Noun Project


    Our walls manage moisture by utilizing the smart vapor permeance benefits of OSB and the hygroscopic properties of cellulose. A semi-vapor open assembly allows for drying in both directions, making it ideal for all climates, and balanced, continuous mechanical ventilation manages interior humidity reducing the amount of moisture that enters the assembly.

  • weather by Vectorstall from the Noun Project


    High-performance tapes used for flashing ensure that no water enters our panels. Roofing is weather tight upon installation with ZIP sheathing.

Indoor Air Quality

Healthy Homes for Life

  • Air Conditioner by Prettycons from the Noun Project


    Highly efficient energy and heat recovery ventilation systems are a requirement of the passive house, and deliver fresh air to the building while exhausting an equal amount of stale and moist air.

  • Earth Environment by Atif Arshad from the Noun Project


    All materials in our homes are screened from an indoor air quality perspective, to avoid unhealthy materials and off-gassing.

Energy Efficiency

Green Building Materials and Systems

  • insulation by Guillermo Guso from the Noun Project


    Levels and material customization to your project requirements. Options for your climate, project design and structural requirements.

  • window by Jaap Knevel from the Noun Project


    Save energy and increase comfort with triple glazed window options that meet the thermal requirements of Passive House.

  • by sahua d


    Fossil fuel free, highly efficient, electric heating and cooling systems powered by renewable energy to achieve zero source energy consumption.

Off-site fabrication of homes and buildings brings much-needed high technology into the building trades. It introduces career paths for the next generation of the construction workforce. It also fosters new levels of respect for the building trades by introducing sophisticated machinery and processes to an industry that hasn’t seen much real innovation.

How We Build Passive Multifamily Units

Bensonwood building enclosure systems have been capable of meeting the rigorous passive house standards for over a decade. Multifamily projects designed and built with our enclosure systems can easily achieve PHIUS certified performance. A passive house results in long-term comfort for residents, low cost of ownership, and better health for our planet. Designers and developers can take advantage of Bensonwood's Tektoniks panels to incorporate our PHIUS-ready building systems into their designs.

A Better Way to Build

The Prefab Homebuilding of the Future

Prefabricated components are built off-site at our facility and then assembled on-site. This method removes time and costs. Bensonwood began using off-site manufacturing with its timberframe division and applied the best practices to panel fabrication.


Virtual Build

Computer-aided design

All components start out as 3D models and undergo a verification process for accuracy before any manufacturing begins.



Off-site Manufacturing

Our building systems division makes all precision prefab components in a dependable factory environment.


Factory Install

Finsishing Components

Finishing component installation happens in the factory, eliminating costly mistakes at the construction site.



Weatherproof BUndles

Bundles of weatherproof building elements shipped to the construction site arrive safely.

Site Assembly

Building components are easily assembled at the construction site with minimal waste.

Our Manufacturing

Bensonwood | Tektoniks | Unity Homes

Our new 110,000-square-foot production facility in southwestern New Hampshire will better serve the passive house market with our new Tektoniks building components brand. The efficient manufacturing technology of Tektoniks produces panels and air-tight building envelopes using our unique building systems for wall, floor and roof panels.

Our Capacity

Advancing in production and finishing

The production capacity and the amount of finishing involved in the component systems will increase for both Bensonwood and Unity Homes. Soon panels will be sent to job sites with wiring and siding preinstalled, and eventually completed bathrooms will be delivered as prebuilt pod systems.

A Customized Approach

Scalable for PHIUS Certification

All of our standard panel designs can be adapted using greater framing depths and continuous insulation. Our wall, roof, and floor assemblies can be scaled for different insulation values, meaning projects can achieve PHIUS certification or performance.

High-performance prefab wall systems ready to get any project to PHIUS standards.

Why we need more Passive Homes today

Residential and commercial buildings are responsible for an enormous quantity of global energy use, resource consumption, and greenhouse gas emissions. Residential energy use accounts for 20% of the total US energy consumption
