Passive House is the most rigorous building energy standard in the world
Bensonwood building enclosure systems have been capable of meeting these uncompromising standards of Passive House for over a decade.
High-Performance & Comfort
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
AIRTIGHTNESS
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.
MOISTURE MANAGEMENT
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.
FLASHING DETAILS
High-performance tapes used for flashing ensure that no water enters our panels. Roofing is weather tight upon installation with ZIP sheathing.
HEAT/ENERGY RECOVERY VENTILATION
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.
LOW/NO VOC MATERIALS
All materials in our homes are screened from an indoor air quality perspective, to avoid unhealthy materials and off-gassing.
CONTINUOUS INSULATION OPTIONS
Levels and material customization to your project requirements. Options for your climate, project design and structural requirements.
HIGH-PERFORMANCE WINDOWS
Save energy and increase comfort with triple glazed window options that meet the thermal requirements of Passive House.
HIGH-PERFORMANCE HEATING AND COOLING
Fossil fuel free, highly efficient, electric heating and cooling systems powered by renewable energy to achieve zero source energy consumption.

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.
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.
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.
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
