Experienced Passive House Builders

By following the Passive House standard, we create buildings that use less energy, provide healthy and quiet indoor environments, and cost less to operate. Our Passive House design build projects include office buildings, multifamily buildings, and custom homes and communities. 

Passive Houses typically include the following features:

  • Continuous insulation (no thermal bridging)

  • High-performance windows and doors

  • Mechanical ventilation with heat recovery  

  • An airtight building building envelope 

  • High-quality insulation

  • Passive solar orientation

Passive House Benefits

Increased thermal comfort. High-quality insulation and airtight construction leads to fewer drafts and more even, consistent temperatures. 

Superior indoor air quality. Airtight floors, roofs and walls have the potential to nearly eliminate air leakage and drifting toxics, including dust, pollen and indoor air pollutants. Meanwhile, efficient ventilation systems ensure continuous, fresh filtered air is brought into the building, while stale air is taken out. 

Noise reduction. Many people appreciate above all else the peace and quiet that comes with living and working in a Passive House. 

Low energy expenses. Passive Houses require a fraction of the energy that a typical home requires, resulting in low energy bills. 

Low Maintenance. Buildings designed to meet the Passive House standard are designed to endure for generations. The components we use, such as triple-pane windows and doors, are extremely durable.
